Use of systemic disease signs to assess disease severity in dairy cows with acute coliform mastitis

OBJECTIVE: To evaluate the use of systemic disease signs for classifying severity of acute coliform mastitis in dairy cows. DESIGN: Prospective cohort study. ANIMALS: 144 dairy cows. PROCEDURE: Cows were examined at the time of initial identification of disease (time 0) and classified as having mild, moderate, or severe disease on the basis of rectal temperature, hydration status, rumen contraction rate, and attitude. A CBC and serum biochemical analyses were performed, and milk samples were submitted for bacterial culture at time 0 and 48 hours later. RESULTS: 69 cows were classified as having mild disease, 44 as having moderate disease, and 31 as having severe disease. Median WBC and neutrophil counts were significantly lower in cows with moderate or severe disease at time 0 than in cows with mild disease. Band neutrophil count was significantly higher at 48 hours and serum calcium concentration was significantly lower at time 0 and at 48 hours in cows with severe or moderate disease, compared with cows with mild disease. Twenty-eight, 51, and 77% of cows with mild, moderate, and severe disease, respectively, had > 100,000 colony-forming units/ml of milk at time 0. The odds that a cow with severe disease would die or be culled were 3.6 times the odds for a cow with moderate disease and 11.2 times the odds for a cow with mild disease. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that a classification scheme based on readily observable systemic disease signs can be used to classify disease severity in cows with acute coliform mastitis.     

COMPARISON OF UPPER GASTROINTESTINAL RADIOGRAPHIC FINDINGS TO HISTOPATHOLOGIC OBSERVATIONS: A RETROSPECTIVE STUDY OF 41 DOGS AND CATS WITH SUSPECTED SMALL BOWEL INFILTRATIVE DISEASE (1985 to 1990)

It was the intent of this study to define which, if any, radiographic observations corresponded with specific causes of diffuse infiltrative small bowel disease and if radiographic findings could differentiate inflammatory disease from neoplastic disease and either of them from normal. Bowel spasticity, luminal narrowing, and thumbprinting tend to indicate the presence of tumor more often than inflammatory disease. Increased bowel gas in cats and barium adhesion in dogs and cats suggest that a component of enteritis is present. Decreased bowel gas in dogs is more often associated with obstructive disease, but is not helpful in differentiating diffuse inflammatory disease from diffuse neoplastic disease. While several observations that can foster differentiation of neoplastic from inflammatory disease were found, this study also indicated that the UGI lacks a high degree of predictive value other than to indicate the presence of infiltrative small bowel disease.     

Annual disease incidence in Colorado cow-calf herds participating in rounds 2 and 3 of the National Animal Health Monitoring System from 1986 to 1988

Thirty-nine and 47 randomly selected Colorado cow-calf operations participated in the National Animal Health Monitoring System (NAHMS) during rounds 2 (October 1986 to September 1987) and 3 (October 1987 to September 1988), respectively. Data on the incidence of disease conditions within each herd were collected by federal and state Veterinary Medical Officers and university veterinarians through monthly visits to the ranches. Annual disease incidence for disease classes and the most frequently reported individual disease conditions were determined and expressed on a per 100 cow basis. The mean annual disease incidences for all diseases in these herds were 48.8 and 47.7 new cases per 100 cows for rounds 2 and 3, respectively. The ranges for herd annual disease incidence were wide in both study years. The enteric disease class had the highest mean annual disease incidence in both years of the study, and this was primarily because of diarrhea of unknown cause in calves. Diarrhea of unknown cause accounted for approximately 25% of all new disease cases in both rounds of the study. The mean annual disease incidences were not different for any disease class between the two rounds. The data indicate that, on the average, diarrhea of unknown cause, pneumonia, dystocia, foot rot (interdigital necrobacillosis), pinkeye (infectious keratoconjunctivitis), respiratory tract infection, death of unknown cause, and nonpregnancy had the highest incidences in these Colorado beef herds during the study period. However, because of the wide variation of the predominant disease problems between herds, a herd's disease history as well as the common disease problems in the geographic area of a herd must be considered in designing a herd health program.

Swine vesicular disease: an overview

Swine vesicular disease (SVD) is a notifiable viral disease of pigs included on the Office International des Epizooties List A. The first outbreak of the disease was recognized in Italy in 1966. Subsequently, the disease has been reported in many European and Asian countries. The causative agent of the disease is SVD virus which is currently classified as a porcine variant of human coxsackievirus B5 and a member of the genus enterovirus in the family picornaviridae. From a clinical point of view, SVD is relatively unimportant, rarely causing deaths and usually only a minor setback to finishing schedules. However, the clinical signs which it produces are indistinguishable from those caused by foot-and-mouth disease, and its presence prevents international trade in pigs and pig products. This article reviews recent findings on all aspects of the virus and the disease which it causes.     

犬牙周病的临床研究进展

牙周病(periodontal disease, PD)是由细菌在牙齿表面聚集形成的牙菌斑和牙结石逐渐侵蚀牙周组织,引发周围组织炎症的一类疾病。根据疾病的发展进程,可分为齿龈炎与牙周炎2个阶段。在小动物临床疾病中牙周病尤为常见,世界范围内约有80%的成年犬患有该病。由于饲主对于犬的口腔保健意识薄弱且该疾病隐秘性较高,患犬就诊时往往已出现牙周支持组织不可逆的损伤,细菌及其毒力因子通过血液循环进入全身从而引发系统性疾病的风险大大提高。但目前犬牙周病的核心致病菌属、菌群失调的原因与发病机制尚不明确。因此,笔者基于高通量测序方法的病原学研究结果,分析与疾病发展相关的微生物群。同时,整合目前世界通用的最新犬牙周病临床诊断分级标准及犬牙周病的中西医防治方案,分析犬牙周病与全身系统性疾病之间的相关性,系统综述犬牙周病在国内外小动物临床领域的研究进展,以期为该类疾病的临床诊疗提供理论参考,推进兽医师在临床实践中更高效地开展该类疾病的诊疗工作,并为犬牙周病相关的临床研究提供思路。

Glomerular disease

Glomerular diseases are a leading cause of chronic kidney disease in dogs but seem to be less common in cats. Glomerular diseases are diverse, and a renal biopsy is needed to determine the specific glomerular disease that is present in any animal. Familial glomerulopathies occur in many breeds of dogs. However, most dogs with glomerular disease have acquired glomerular injury that is either immune-complex mediated or due to systemic factors, both of which are believed to be the result of a disease process elsewhere in the body (i.e., neoplastic, infectious, and noninfectious inflammatory disorders). A thorough clinical evaluation is indicated in all dogs suspected of having glomerular disease and should include an extensive evaluation for potential predisposing disorders. Nonspecific management of dogs with glomerular disease can be divided into 3 major categories: (1) treatment of potential predisposing disorders, (2) management of proteinuria, and (3) management of uremia and other complications of glomerular disease and chronic kidney disease. Specific management of specific glomerular diseases has not been fully studied in dogs. However, it may be reasonable to consider immunosuppressive therapy in dogs that have developed a form of glomerulonephritis secondary to a steroid-responsive disease (e.g., systemic lupus erythematosus) or have immune-mediated lesions that have been documented in renal biopsy specimens. Appropriate patient monitoring during therapy is important for maximizing patient care. The prognosis for dogs and cats with glomerular disease is variable and probably dependent on a combination of factors. The purpose of this article is to discuss the general diagnosis and management of dogs with glomerular disease.     

A neurological syndrome in a free-living population of possums (Trichosurus vulpecula)

AIMS: To determine the clinical and pathological features of a neurological disease syndrome in a free-living possum population in New Zealand and to compare this syndrome with wobbly possum disease. METHODS: An outbreak of a neurological disease in possums in the Rotorua district was investigated in 1994. A variety of tissues was collected and investigated microbiologically and histopathologically. Tissues stored from clinically affected possums were homogenised, clarified and inoculated into healthy possums by the intra-peritoneal route. The clinical signs and histopathological lesions in naturally-infected and in experimentally-inoculated possums were assessed and compared with those of possums affected with wobbly possum disease. RESULTS: Histopathological investigation of three of the naturally-affected possums revealed non-suppurative encephalitis with perivascular cuffing, diffuse non-suppurative meningitis and focal non-suppurative myocarditis. These lesions were suggestive of a viral infection. No pathogenic bacteria were recovered and no viruses were isolated in tissue culture. A neurological disease, indistinguishable from wobbly possum disease, was reproduced in five out of the eight experimentally inoculated possums. In two experimental cases the clinical signs were very mild and, in most cases of the natural and experimental disease, histopathological lesions in the central nervous system were mild in comparison with wobbly possum disease. Possums which did not develop clinical signs of neurological disease or have lesions in the central nervous system did have infiltrations of mononuclear inflammatory cells in the liver and kidney. CONCLUSIONS: This neurological disease, reported for the first time in a free-living population, closely resembles and may be the same as wobbly possum disease. The milder nature of this disease could suggest there may be more than one strain of the aetiological agent.
