From Osler to Olafson. The evolution of veterinary pathology in North America

Most branches of biological science in North America developed first in the United States, and later were taught and practiced in Canada. An exception was veterinary pathology, which as a discipline taught in veterinary colleges and as a field of research, developed first in Canada, and from there crossed the border to the United States. Pathology was first taught at the Montreal Veterinary College, founded in 1866 by Duncan McEachran, a graduate of the Edinburgh Veterinary College. From the outset, he formed a close association with the medical faculty of McGill University, permitting his students to attend the same classes in the basic subjects with the medical students. Eventually, the Montreal Veterinary College became formally affiliated with McGill University, as the Faculty of Comparative Medicine and Veterinary Science. The McGill veterinary faculty was forced to close for economic reasons in 1903, but it left an enduring legacy, particularly in the field of veterinary pathology. The legacy, a novel concept in the 1870's, was that pathology was the cornerstone of a veterinary education; the place where anatomy, physiology, chemistry and botany met with the clinical subjects, and gave the latter meaning. This tradition was formed at the Montreal Veterinary College by the world renowned physician William Osler, North America's leading medical teacher, whom McEachran had invited to teach at the College in 1876 in addition to his duties in the faculty of medicine. Osler had studied with Virchow in Berlin and applied his methods of autopsy technique and of scientific inquiry to his teaching of both human and veterinary pathology at McGill. Osler also undertook investigations into various diseases of domestic animals, at the request of McEachran, who doubled as Chief Veterinary Inspector for the Dominion Department of Agriculture. Osler left McGill University in 1884. Only after that year did other North American veterinary schools adopt pathology as a discipline of instruction. However, by 1884, Osler had already left his indelible imprint on the students (both medical and veterinary) he had taught in Montreal, one of whom took over the teaching of pathology in the veterinary college. Another, who followed Osler's example and also studied in Berlin with Virchow, wrote the first book in the English language on veterinary post mortem technique in 1889.(ABSTRACT TRUNCATED AT 400 WORDS)     

"Veterinary genetics" and "Women in veterinary medicine", the main themes of the 31rst WAHVM-congress in Brno (Czech Republic)

The congress, held from 6-10 September 2000 on the campus of the University of Veterinary and Pharmaceutical Sciences in Brno, attracted 102 participants from 23 countries, plus 20 accompanying persons. Next to a report on some special events as visits to the Veterinary Museum and the Mendelianum, after laying a wreath at Mendal's tomb, summaries or annotations are given of the lectures presented. There were five invited speakers in the session on "Veterinary genetics" and one invited speaker in the session devoted to "Women in veterinary medicine". Three guest speakers could be invited thanks to a grant by the "History of Medicine Programme" of The Wellcome Trust in London. The total number of lectures was 34. Besides some historical veterinary films were shown, and 34 posters were on display. The congress was very well organized by a team presided by em.-professor Rudolf B?hm.

WAAVP/Pfizer award for excellence in teaching veterinary parasitology: teaching of veterinary parasitology--quo vadis?

Some thoughts on training and recruitment of academic teachers and future trends in teaching veterinary parasitology are presented with emphasis on the European situation. It is underlined that research is an indispensable basis for academic teaching. Besides a broad scientific background of the teacher, motivation and teaching methods are also important. Many academic teachers do not receive formal training in teaching methods. In order to improve future education, training of staff members in teaching methods should be promoted. Quality control of teaching and research, already established in many schools, should generally be introduced. Teaching is mostly underestimated in relation to research. Therefore, more weight should be placed on the former both in selecting scientists for the career as academic teachers and in evaluating and ranking departments for their academic activities. In the future veterinary medicine will have to cope with profound changes in the society and the veterinary profession, and the progressing European unification will enhance trends for internationalizing teaching curricula. Therefore, veterinary medicine has to reconsider the teaching subjects and methods and to lay more emphasis on flexibility, skills of problem-solving and self-learning and on training for life-long learning. At present there is an ongoing discussion on the question how to teach veterinary medicine, including veterinary parasitology. There are various options, and some of them are discussed, namely, the disciplinary and the problem-based/organ-focussed approaches. It is concluded that for teaching of veterinary parasitology and related disciplines a combined disciplinary and problem-based approach offers the best chances for fulfilling the requirements of teaching for the future. In the curriculum of undergraduate teaching of veterinary medicine at least 70-90 h should be dedicated to veterinary parasitology using a disciplinary and taxonomic approach. Additional hours are required for instructions on clinical cases in approaches focussed on animal species and/or organ diseases. As there is a need for discussing teaching issues, post-graduate specialization, and continuing education in parasitology and related disciplines on national and international levels, it is recommended to WAAVP to include regular workshops on teaching in the programmes of the biannual conferences, and to establish a permanent committee which should collect information and submit proposals for improvement of teaching veterinary parasitology.     

Veterinary medicine protecting and promoting the public's health and well-being

Dr. Calvin Schwabe's vision of "One Medicine" has long inspired many in the public health community to strive toward bringing human and veterinary medicine together to improve the public's health and well-being around the world. In an increasingly human-dominated world, as Dr. Schwabe suggested many years ago, human health provides the most-logical unifying or apical cause in veterinary medicine's hierarchy of values. Veterinarians in all aspects of the profession-have opportunity and responsibility to protect the health and well-being of people in all that they do, including protecting food security and safety; addressing threats to antibiotic sensitivity; preventing and controlling zoonotic emerging infectious diseases; protecting environments and ecosystems; participating in bio- and agro-terrorism preparedness and response; using their skills to confront non-zoonotic diseases (such as malaria, HIV/AIDS, vaccine preventable diseases, chronic diseases and injuries); strengthening the public-health infrastructure; and advancing medical science through research. This article provides an overview of contributions made by veterinarians in each of these areas, and discusses the challenges to be overcome and the need for strategic thinking and action to achieve the vision of "one medicine".     

Methicillin-resistant Staphylococcus aureus (MRSA) in veterinary medicine: a "new emerging pathogen"?

The problem of nosocomial infections is of increasing importance in veterinary medicine. As an example, this review summarizes current knowledge regarding methicillin-resistant Staphylococcus aureus (MRSA) as a typical example, as these pathogens are the most important agents of nosocomial infections in human medicine worldwide and are being increasingly reported in veterinary medicine. MRSA are classified by their ability to be resistant against oxacillin/methicillin, this feature being confered by mecA, a gene which was acquired by horizontal gene transfer of the staphylococcal gene cassette (SCCmec). It is this genetic information that enables MRSA to be resistant against all penicillins, cehalosporins and carbapenems. In addition, MRSA are often resistant against a variety of other antiinfectives, i.e. aminoglycosides, macrolides, lincosamide, streptomycins, tetracyclin, chloramphenicol, but also against fluorquinolones and rifampicin. Presumably, these highly adapted strains are particularly able to acquire resistance genes located on plasmids or transposons.They are also able to develop point mutations, further leading to resistant phenotypes. If these pathogens are leading to infectious diseases, veterinarians may be confronted with a worst-case scenario, being left without any antiinfective therapeutic. As Staphylococcus aureus is highly tenacid, professional hygiene management is of utmost importance. The increasing number of published sporadic MRSA infections, MRSA-infectious diseases as well as MRSA outbreaks in veterinary medicine justifies their recognition as a "New Emerging Pathogen". So far, horses and dogs are mostly affected by MRSA. Although transmission between humans and animals has been reported occasionally, the sources, routes of transmission or the epidemiological relevance of MRSA infections in animals are far from being understood. Therefore, epidemiological investigations utilizing molecular typing tools are mandatory. Typing tools like multilocus-sequence-typing (MLST), pulsefield-gelelectrophoresis (PFGE), sequence analysis of the gene encoding protein A (spa-typing) as well as SCCmec-typing are all at hand.     

Future directions in training veterinarians for careers in toxicological pathology in the United Kingdom

There is currently a global shortage of veterinary pathologists in all sectors of the discipline, and recruitment of toxicological pathologists is a particular problem for the pharmaceutical industry. Efforts to encourage veterinarians to consider alternative career paths to general practice must start at the undergraduate level, with provision of structured career guidance and strong role models from pathology and research disciplines. It is also imperative that both the importance of biomedical research and the role of animal models be clearly understood by both university staff and undergraduates. Traditionally, much post-graduate training in toxicological pathology is done "on the job" in the United Kingdom, but completion of a residency and/or PhD program is recognized as a good foundation for a career in industry and for successful completion of professional pathology examinations. New models of residency training in veterinary pathology must be considered in the United Kingdom to enable a more tailored approach to training toward specific career goals. A modular approach to residency training would allow core skills to be maintained, while additional training would target specific training requirements in toxicological pathology. Exposure to laboratory-animal pathology, toxicology, research methodology, and management skills would all be of benefit as an introduction to a career in toxicological pathology. However, long-term funding for UK residencies remains a problem that must be resolved if future recruitment needs in veterinary pathology are to be met.     

Clinical pathology of amphibians: a review

Amphibian declines and extinctions have worsened in the last 2 decades. Partly because one of the main causes of the declines is infectious disease, veterinary professionals have increasingly become involved in amphibian research, captive husbandry, and management. Health evaluation of amphibians, free‐living or captive, can benefit from employing the tools of clinical pathology, something that is commonly used in veterinary medicine of other vertebrates. The present review compiles what is known of amphibian clinical pathology emphasizing knowledge that may assist with the interpretation of laboratory results, provides diagnostic recommendations for common amphibian diseases, and includes RIs for a few amphibian species estimated based on peer‐reviewed studies. We hope to encourage the incorporation of clinical pathology in amphibian practice and research, and to highlight the importance of applying veterinary medicine principles in furthering our knowledge of amphibian pathophysiology.     

Veterinary pathology in Europe in the light of the congresses of the European Society of Veterinary Pathology in the last decade

This paper presents the main trends in the activity of European veterinary pathologists in the context of their oral presentations (plenary lectures and short presentations) and posters provided during annual meetings of the European Society of Veterinary Pathology (ESVP), in the decade 1997-2006. It was found that the issue that was most often brought up in the meetings was organ pathology (566 presentations). Infectious and parasitical diseases were only slightly less frequent (548 presentations). Oncology was another common issue (404 presentations). During this decade, 52 plenary lectures were presented, 765 oral presentations and 1 072 posters. Altogether, 1 889 presentations were made, which is between 127 and 238 per year. Research by Polish scientists accounted for 3.16% of all presentations. Additionally, the subject matter discussed at the annual meetings is analysed, and the trends in the development of veterinary diagnostic pathology and broad pathology education are indicated. It is shown that veterinary pathology enhances knowledge in the field of veterinary medicine by fulfilling a cognitive and diagnostic role.     

Original procreation or generational change? The investigation of cysticercus and tapeworms

The doctrine of the abiogenesis postulated the origin of human and animal intestinal worms from "not complete digested ingesta". Indeed Peter Simon Pallas (1741-1811) defined already 1760 in his dissertation that endoparasitic worms reproduce themselves by eggs. But he characterised the nature of cysticercus as "pathologically degenerated tail bladder". In 1856 Rudolf Leuckart (1822-1898) paraphrased the alternation of generation with "marvellous metamorphoses and peculiar form of development". The Dane Johannes Japetus Smith Steenstrup (1813-1897) recognised finally the principle of the alternation of generation and Gottlob Friedrich Heinrich Küchenmeister (1821-1890), a physician at the Saxon city Zittau realised the special correlation between the alternate and end host of tapeworms. Both, Leuckart and Küchenmeister proved their insights by animal and human experimentations.     

CLINICAL OSMOMETRY IN VETERINARY MEDICINE

Although the concept of osmosis and osmotic pressure is one which is encountered repeatedly in the many disciplines within veterinary medicine, it is difficult to find a general discussion of the use of osmometry in clinical veterinary medicine. The following is an attempt to provide a summary of present knowledge in this area.     

Legal aspects of the use of footbaths for cattle and sheep

Claw diseases pose a major problem for dairy and sheep farms. As well as systemic treatments of these illnesses by means of drug injection, veterinarians discuss the application of footbaths for the local treatment of dermatitis digitalis or foot rot. On farms footbaths are used with different substances and for various purposes. The author presents the requirements for veterinary medicinal products (marketing authorization and manufacturing authorization) and demonstrates the operation of the "cascade in case of a treatment crisis". In addition, the distinction between veterinary hygiene biocidal products and veterinary medicinal products and substances to care for claws is explained.     

Veterinary medical work of Johann Christian Polycarp Erxleben, the first teacher of veterinary medicine in Germany]

Erxleben could be regarded as the founder of the modern, systematic and scientific training of verterinary surgeons in Germany. Thanks to an open-minded up-bringing and a large interest in other scientific fields beyond his medical studies he acquired the ideal basis to turn veterinary medicine into a subject at university. He acquired his knowledge in veterinary medicine by reading numerous veterinary books and by visiting the Netherlands and France and the expert of horses Johann Baptist von Sind. Since 1770 he started with veterinary lessons. When planning his teaching, he tried to avoid the mistakes made by the first schools in France. In order to do so he attached a great importance to a fundamental but practical training. Erxleben also wrote two volumes about veterinary medicine, which he used as a literary basis for his lessons.     

Historical perspective and future directions in training of veterinary pathologists with an emphasis on zoo and wildlife species

This article discusses the history of the field of zoo and wildlife pathology, training opportunities for veterinary students and graduate veterinarians, and current and future job opportunities. The niches occupied by veterinarians in this field and their contributions to animal and human health are also highlighted. The field of zoo and wildlife, or "non-traditional" species, pathology has its roots in comparative anatomy, zoology, wildlife biology, and medical pathology in the mid- to late nineteenth century. The initial emphasis was on comparisons between animal and human diseases or on management of game animals. Veterinarians became increasingly involved during the twentieth century, gradually changing the emphasis to improvement of conservation strategies, captive care, and elucidation of diseases of concern for the animals themselves. Currently there are several zoos and wildlife agencies in the United States employing full-time veterinary pathologists. Private and government diagnostic laboratories, veterinary schools, and other academic institutions in the United States with pathology departments are other employers. The field requires post-DVM training by means of a residency program leading to board certification, graduate school (MS or PhD degrees), or both. Veterinary students can gain valuable experience in the field through externships and, at some schools, through elective courses in the curriculum. Current concerns about ecosystem health, bioterrorism, and the recognition that captive and free-ranging wildlife can serve as sentinel species will increase the demand for veterinary pathologists choosing this very rewarding career path specializing in non-traditional species.     

Can online conference systems improve veterinary education? A study about the capability of online conferencing and its acceptance

In veterinary medicine, there is an ongoing need for students, educators, and veterinarians to exchange the latest knowledge in their respective fields and to learn about unusual cases, emerging diseases, and treatment. Networking among veterinary faculties is developing rapidly, but conferences and meetings can be difficult to attend because of time limitations and travel costs. The current study examines acceptance of synchronous online conferences, seminars, meetings, and lectures by veterinarians and students. First, an online survey on the use of communication technology in veterinary medicine was made available for 15 weeks to every German-speaking veterinary university and via professional journals and an online veterinary forum. A total of 1,776 persons (620 veterinarians and 1,156 students) participated. Most reported using the Internet at least once per day; more than half reported using instant messengers. Most participants used the Internet for communication, but less than half used Skype. Second, to test the spectrum of tools for online conferences, a variety of "virtual classroom" systems (netucate systems iLinc, Adobe Acrobat Connect Pro, Cisco WebEx, Skype) were used to deliver student lectures, veterinary continuing-education courses, and academic conferences at the University of Veterinary Medicine, Hannover (TiHo). Of 591 participants in 63 online events, 99.4% rated the virtual events as enjoyable, 96.1% found them useful, and 92.4% said that they learned a lot. Participants noted that the courses were not tied to a certain place, and thus saved time and travel costs. Online conference systems thus offer new opportunities to provide information in veterinary medicine.     

Markers of Osteoarthritis: A Review of the Literature

There may be a great potential in the use of diagnostic "markers" of osteoarthritis in synovial fluid to diagnose the disease in an earlier stage and perhaps assess the severity of the disease and monitor the effect of a treatment. In the present study, potential markers are characterized, discussed, and grouped according to the latest knowledge on the etiology, pathogenesis, and pathology of osteoarthritis. They are grouped according to their origin as either cartilage degradation products, or related to the mechanisms of cartilage degradation, or related to chron-drocytic anabolic activity during disease, or related to genetic disorders. Also potential markers that have not yet been studied clinically or experimentally are discussed. Examples of the progress that has been made in human medicine approaching reliable diagnostic markers that should also be tried in veterinary medicine are described.

From horse doctor to cow leech to veterinary manager. Regulation of the market for veterinary services in historical perspective

In the course of the last two centuries veterinarians succeeded in gaining a monopoly with respect to a number of specific tasks within society under the motto "to the benefit of man and animal alike". Today, a veterinary infrastructure exists in the western world, which is usually taken for granted by society. Before the responsibility for maintaining animal resources and protecting both animal and human health were entrusted to veterinarians, both the process of scientific progress and professionalization of veterinary medicine were necessary. In this paper the regulation of the market for veterinary services in The Netherlands is decribed. Until World War II, the military and the colonies represented a major demand for veterinary services. A healthly livestock has always been considered as a main concern by the Dutch government with respect to the domestic food supply as well as exports. State intervention concerning veterinary medicine therefore focused on the organized campaigns against livestock diseases. Early national veterinary legislation originated from this concern, as is still the case today within the EU framework. The protection of human health only became part of the veterinary professional domain at a relatively late stage. Due to a strong economic growth from the 1960s onwards, veterinary practice was extended with the care for an increasing number of companion animals. The veterinary profession and its employment are subject to changes in society, such as the number of animals and the significance that is paid to the different species. In 1900 there were 4 million production animals in The Netherlands, while the human population counted 5 million. One century later, not less than approximately 130 million farm animals and 30 million companion animals are living in this country, which now has about 16 million inhabitants. Consquently, the total number of active vets increased from about 250 to 4,000 in the same period, while the number of group and solo practices both increased.
