Ultrasonography was used to diagnose pericardial effusion, atrial dilatation and liver masses in a spur-thighed tortoise which was more than 80 years old and suffering from posthibernation anorexia, lethargy, oedema and pneumonia. The tortoise was treated twice with frusemide and ceftazidime for the pneumonia, resulting each time in a temporary remission for about a month. After a further recurrence, the animal was euthanased and the lesions predicted by ultrasound were confirmed postmortem. It is suggested that ultrasound may be useful for the differentiation of cardiac problems from other causes of posthibernation lethargy in the tortoise.

This paper describes the clinical and laboratory findings from 264 cases of toxic mastitis in cows in Northern Ireland between October 1995 and May 1997. Nearly all the cases occurred during the winter housing period, with 84 per cent occurring between November and March inclusive, and 30 per cent in March. Sixty per cent of the cases occurred within one month of calving, and 29 per cent within four days of calving. The most common clinical signs were lethargy (92 per cent), discoloured milk (90 per cent), anorexia (72 per cent), tachypnoea (23 per cent), diarrhoea (23 per cent), recumbency (18 per cent) and staggering (15 per cent). Severe pyrexia (18 per cent) and clinical dehydration (44 per cent) were relatively common findings. Pure growths of Escherichia coli were isolated from 50 per cent of the milk samples, but 11 per cent yielded no bacterial growth. In vitro sensitivity tests indicated that enrofloxacin was effective against 98 per cent of the bacteria isolated, and framycetin and amoxycillin/clavulanic acid against 91 per cent. Abnormally high blood urea levels were observed in 31 per cent of cases, high blood creatinine levels in 42 per cent, and severe leucopenia in 56 per cent. Of the cases which were followed up, 14 per cent died, 21 per cent were culled early and a further 22 per cent lost milk production from the affected quarter.

A six-year-old Staffordshire bull terrier had a four-week history of progressive lethargy, ascites and exercise intolerance. A mass 3 cm in diameter obliterating the right atrial lumen was detected by echocardiographic examination. There were lactescent pericardial and serosanguineous pleural effusions. Histological and immunochemical examinations showed that the mass was a primary rhabdomyoma.

After being anaesthetised for between one hour 40 minutes and seven hours, five adult horses developed acute neurological signs and extensive cerebrocortical necrosis. Four of them had had abdominal surgery for colic and one had had repeated orthopaedic interventions. Between five hours and seven days after the surgery, all five horses suddenly developed severe signs of a predominantly prosencephalic disturbance: bilateral blindness with normal pupillary light responses, abnormal behaviour varying from propulsive pacing to head pressing profound lethargy and generalised seizures. They were euthanased between 24 hours and three weeks after the onset of these signs. In three of the cases a gross examination of the brain revealed patchy malacia of the cerebral grey matter and some discolouration of the adjacent white matter. Microscopical examination revealed lesions that varied from laminar neuronal necrosis in the grey matter of the cerebral cortex to more diffuse necrosis of the cortex and underlying white matter. Four of the five cases had had a period of hypercapnea while anaesthetised, and two of them (and possibly a third) had also had hypoxaemia.

A distinctive nodular dermatitis induced by Straelensia cynotis, a newly described trombidioid larval mite which resides in hair follicles, was identified in 12 dogs living in France. They all had scattered, small (1 to 3 mm in diameter), pale, firm skin nodules, variable in distribution but always affecting the dorsal regions of the head and trunk; they were distributed over the whole body of seven of the dogs. The animals were otherwise healthy except for three severely infested fox terriers which had a decreased appetite, were lethargic, and whose skin nodules were painful to the touch. The nodules did not induce pruritus. The lesions usually began as erythematous papules which developed into firm pale nodules. The dermatitis resolved within two to 12 months. Topical acaricides were ineffective but the skin nodules regressed after treatments with systemic avermectins. Histologically, each nodule was composed of a dilated follicular ostium containing a well-preserved larval mite, and showed a pseudoepitheliomatous follicular hyperplasia and an abundant perifollicular mucinosis. The larvae were identified as belonging to the genus Straelensia (Acari: Leeuwenhoekiidae). It was clearly established that the three fox terriers had become infested within a fox's den. The nymphs and adults of this species of mite are believed to live in foxes' dens; foxes are considered to be the natural host for the larval stage, and dogs a permissive but occasional host.

Forty-six cats with clinical haemobartonellosis were studied; 75 per cent of the cats of known age were two-and-a-half years old or younger, 50 per cent were intact males and 19.5 per cent were castrated males. The predominant signs of the disease were tachypnoea, lethargy, depression, anorexia, infestation with fleas, pale mucous membranes, icterus, emaciation, dehydration, splenomegaly, anaemia, leucocytosis, increased activities of alanine aminotransferase and aspartate aminotransferase, and azotaemia. Thirty-eight per cent of the cats that were tested for feline leukaemia virus (FeLV) antigen were positive, and 22 per cent of those tested for feline immunodeficiency virus (FIV) antibodies were positive. The prevalence of both FeLV and FIV was much higher than in the general Israeli cat population. The cats infected with both Haemobartonella felis and FeLV had a significantly lower body temperature, were more anaemic and the mean cell volume of their erythrocytes was greater than in the cats with haemobartonellosis alone.

A 12-month prospective study of clinical mastitis was conducted in 482 British dairy herds with a bulk milk somatic cell count (BMSCC) of less than 150,000 cells/ml. The mean proportion of cows in the herd with clinical mastitis was 23.1 per cent (range 0 to 80), with a mean of 1.50 quarter cases per cow. The mean incidence rate of clinical mastitis was 36.7 quarter cases per 100 cow years (range 0 to 208.2). Twelve per cent of the quarter cases showed systemic signs, including inappetence and severe lethargy. Over 22 per cent of quarter cases occurred in the first seven days of lactation and over 50 per cent occurred in the first 90 days of lactation. Cluster analysis indicated that the main difference between herds with a low and average incidence of mastitis was the proportion of clinical cases occurring in the first seven days of lactation, 14 per cent compared with 44 per cent, respectively. The risk of severe clinical mastitis compared with mild clinical mastitis decreased significantly as the individual cow somatic cell count (SCC) in the month before clinical mastitis was diagnosed increased.

Twenty-five weimaraners with recurrent infections or inflammatory disease were investigated; their median age was four months (range two to 36 months), and 11 of them were male and 14 female. Twenty of them showed signs of lethargy, anorexia or pyrexia, 13 had been vomiting or had diarrhoea, 12 had shown signs of pain in the joints or bones and been lame, five had had reactions at the site of an injection, five had generalised lymphadenopathy, three had urinary tract infections and two had recurrent or severe pyoderma. They all had a lower concentration of one or more classes of serum immunoglobulin (IgG, IgM and IgA) than the standard control ranges, and their mean concentration of IgG was significantly lower (P<0.005) than the mean concentration of IgG in 15 clinically normal weimaraners. Of 10 cases for which a complete vaccination history was available, nine had developed clinical signs within five days of being vaccinated. Follow-up data were available from 21 of the 25 dogs for a median period of 24.5 months. One dog died during a symptomatic episode, three were euthanased, six were alive at follow-up but had continued to show clinical signs and 11 had made a full recovery.

An adult male binturong, Arctictis binturong, which had been anorexic and lethargic for seven days became acutely dyspnoeic and died under anaesthesia. A postmortem examination revealed left ventricular hypertrophy with a thrombus occluding the left ventricular chamber. Histological findings included moderate to severe multifocal, vasculocentric myocardial degeneration and necrosis with fibrosis replacing myocardiocytes. Escherichia coli and Proteus mirabilis were grown on cultures. The animal's serum vitamin E and selenium levels were considered adequate. The aetiology of the chronic myocardial changes could not be determined.

Fifteen cats from Italy with Ehrlichia-like inclusion bodies in their neutrophils were studied. They were diagnosed with Anaplasma (Ehrlichia) phagocytophilum infection on the basis of cytological observation of morulae within 1 to 21 per cent of their neutrophils, clinical signs characteristic of ehrlichiosis and their response to doxycycline. The predominant signs of disease were anorexia, lethargy, hyperaesthesia, muscle and joint pain, lameness, neck rigidity, lymphadenomegaly, gingivitis/periodontitis, conjunctivitis, weight loss, incoordination, pale mucous membranes and hyperglobulinaemia. The cat with inclusions in 21 per cent of its neutrophils had suffered arthralgia, tachypnoea, neck rigidity, vomiting and thrombocytopenia for four months, but recovered promptly after treatment with doxycycline.
