Swinepox--skin disease with sporadic occurrence

Swinepox virus infection results in an acute, mild or subclinical course and is characterised by typical poxvirus skin lesions in affected pigs. Additionally, sporadic vertical swinepox virus transmission leads to congenital generalised infection and subsequent abortion or stillbirth. The present report describes the occurrence of epidermal efflorescences in two piglets after intrauterine natural suipoxvirus infection. No clinical abnormalities of the gilt and littermates as well as in other pigs from this herd were present. One of the affected piglets was stillborn and submitted for necropsy, the other animal was alive at birth, but died 3 days later. Histologically, a proliferative to ulcerative dermatitis with epithelial ballooning degeneration and characteristic intracytoplasmatic inclusion bodies was observed. The pathomorphological and histopathological suspected diagnosis of a poxvirus infection was confirmed by electron microscopy. Furthermore, the agent was identified as suipoxvirus by polymerase chain reaction. As demonstrated here, obvious skin lesions in suipoxvirus infection leads to a suspected diagnosis in newborn piglets on macroscopic examination. However, further post mortem examinations, including electron microscopy as well as molecular techniques are essential for the identification of the aetiology and the exclusion of differential diagnoses. Because the disease only affected two pigs there was only a small economic loss. A valid diagnostic plays an important role in advising farmers and for herd health monitoring.     

Development of the population size, contribution of foreign breeds, inbreeding and degree of relationships of the entire Hanoverian scenthound population registered in the stud book of the kennel club Hirschmann e.V

The entire dog population of Hanoveranian Scenthounds registered since the foundation of the kennel club Hirschmann in the year 1894 was analysed for the development of the inbreeding and relationship coefficient and the contribution of Hanoveranian Scenthound population of foreign countries. The analyses were performed using all available pedigree information. In the history, the breeding of the Hanoveranian Scenthound was difficult because of the low number of breeding dogs which was additionally reduced during World War I and II. The mean coefficient of inbreeding of the entire German population was 6.35%. From 1950 to 1990, the mean coefficient of inbreeding increased from 8.3% to 9.7%. In the birth years from 1990 to 2002, the mean coefficient of inbreeding decreased slightly to 9.2%. The rates of inbreeding decreased since 1950. For the last 8 generations the increase of the coefficients of inbreeding per generation was 0.71%. The mean degree of relationship of the entire population was 7.17%, whereby values higher than 75% were found. Gene contributions of 8 other European stud books for the Hanoveranian Scenthound could be found in the German population. Hereby, the Austrian Hanoveranian Scenthounds had the largest impact on the German population with 24.4%. The proportion of genes from the German stud book amounted to 67%.     

Examination of horses with acute colic: clinical and legal aspects

The article provides hands-on advice and scientific background information regarding the management of the equine acute colic patient. It summarizes essential information on the patient's history, clinical examination, and legal aspects. The scope of the history is based on the clinical appearance of the patient. In horses with violent and barely controllable signs of pain, it is limited to colic-associated information such as onset, course and severity of colic signs, and the last time of defecation, as well as prior therapeutic intervention. In these patients, the clinical examination is focussed primarily on the assessment of cardiovascular parameters, rectal temperature, and the patient's behaviour. The nasogastric intubation is an essential part of the examination of a horse with colic to prevent a gastric rupture due to gastric distension. Transrectal palpation is equally important and should always be performed unless there are important reasons to object to this procedure. In most cases, a thorough patient history and clinical examination of an acute colic patient allows the examining veterinarian to make a tentative diagnosis and a prognostic evaluation. This helps with the decision to start a conservative or a surgical therapy. Due to the existing obligatory documentation requirement and the duty to inform patient owners, it is of utmost importance to promptly document one's findings, therapeutic measures, consultations, and information of the patient owner in written form. This supports further therapy and it can also be of relevance in a potentially resulting lawsuit.     

Versuche mit Herbiziden in Gemeiner Ringelblume (Calendula officinalis L.) in Sachsen-Anhalt und Thüringen

Between 2000 and 2005 12 experiments with 18 herbicides were carried out in marigold in experimental stations and on marigold fields of Thuringian farms. The main objective of the tests was to get the necessary data for the authorization procedure according to the regulations of §?18 a PflSchG. Marigold plants are very susceptible against some herbicides Betanal Progress, Goltix Compact + ?l, Kontakt 320 SC, Lentagran WP und Stefes IPU. These herbicides and cause severe damages on this culture. The use oft the herbicides Bandur, BASTA and further herbicides with the active ingredient Glufosinat was authorized for the application in marigold according the regulations of §?18 a PflSchG in the past. The herbicides Devrinol FL, Fusilade MAX, Goltix 700 SC, Roundup UltraMAX und Targa Super can be used in artichoke according the regulations of §?18 b PflSchG. These herbicides aren??t enough for the chemical control of weeds likeEchinochloa spec.,Galinsoga spec., Polygonum spec. in marigold. In addition to the application of the herbicides mechanical measures are necessary.     

Zur Anwendung von 2,4-Dichlorphenoxyessigsäure (2,4-D) bei Tomaten. Der Metabolismus des 2,4-D in Tomatenfrüchten

Due to 2,4-D-treatments of tomato inflorescences mainly glycosides of 4-Hydroxy-2,3-dichlorophenoxyacetic acid (4-OH-2,3-D) are formed in the fruits, and to a lesser extent of 4-Hydroxy-2,5-dichlorophenoxyacetic acid (4-OH-2,5-D), too. Acid hydrolysis of n-butanol extract also yielded 2,4-D, and in addition an unidentified metabolit. Only very small amounts of unchanged 2,4-D residues were detected (lower than 1 ppb).     

Woher kommen wir und wohin gehen wir? – Analyse des deutschen Erwerbsobstbaus anhand eines Branchenlebenszyklus-Modells

Cassia et al. (2006) claim that each industry develops along a specific industry life cycle with four stages: introduction, growth, maturity and decline. This essay tries to analyze the German fruit-growing industry by the means of the industry life cycle model. The main aspects of the analysis are “consumption and prices”, “competition”, “product innovation” and “process innovation”. In summary, the German professional fruit-growing industry might be classified as to be in the mature stage.
