A 16-month-old Charolais bull was examined because of acute onset of scrotal and hind limb edema, fever, tachycardia, tachypnea, anorexia, and lethargy. Scrotal circumference on initial examination was 48 cm. Clinicopathologic abnormalities included microcytic, normochromic anemia and numerous Eperythrozoon organisms in blood smears. Results of immunohistochemical staining of a skin biopsy specimen suggested that the edema was the result of an Arthus-type reaction. Semen quality deteriorated rapidly, and the bull was aspermic within 7 days. The bull was treated with oxytetracycline, and the anemia and edema gradually subsided. Eperythrozoon organisms were not detected in blood smears after 3 days. Six months after initial examination, results of physical examination and semen evaluation were normal. We hypothesize that scrotal edema caused failure of testicular thermoregulation, resulting in transient production of abnormal sperm and infertility.

Medical records of 35 cattle with small-intestinal volvulus were reviewed. Surgical correction was performed on 32 cattle, and 17 of these cattle were discharged from the hospital. Mean duration of clinical signs for survivors was not significantly different from that for nonsurvivors, and the most commonly recorded clinical signs were abdominal pain, anorexia, lethargy, abdominal distention, and dehydration. Physical examination of cattle with intestinal volvulus revealed tachycardia, tachypnea, and normothermia. Rectal examination findings included distended small intestine, scant feces or mucus, and tight bands coursing dorsoventrally in the middle portion of the abdomen. Clinicopathologic testing revealed azotemia, hypocalcemia, hyperglycemia, and leukocytosis with a left shift. Nonsurvivors had significantly lower mean preoperative venous blood pH and mean base excess and higher mean serum potassium concentration than did survivors. A diagnosis of volvulus of the entire small intestine was made during surgery in 25 cattle, whereas volvulus of the distal jejunum and ileum was diagnosed during surgery in 7 cattle. Survival rate following surgical correction of volvulus of the entire small intestine (44%) was not significantly different from survival rate following surgical correction of volvulus of the distal jejunum and ileum (86%). However, survival rate for dairy cattle (63%) was significantly higher than survival rate for beef cattle (22%). To determine potential risk factors for the development of small-intestinal volvulus, epidemiologic data from cattle admitted to veterinary teaching hospitals throughout North America were collected by searching records entered into the Veterinary Medical Data Base.(ABSTRACT TRUNCATED AT 250 WORDS)

We studied 57 infants < or = 14 days of age referred for possible enterovirus (EV) infection to assess the accuracy of that clinical diagnosis and describe the natural history of neonatal EV infection. Twenty-nine neonates proved to have EV infection, 23 had illnesses compatible with (but not proven to be) EV infection, and 5 had alternative diagnoses: bacterial infections (2); herpes simplex virus infection (1); and metabolic disorders (2). Neonates with proved EV infection were generally full term and had uncomplicated immediate postnatal periods but high percentages of ill contacts. Neonatal symptoms and signs included fever, irritability, anorexia, lethargy, hypoperfusion, rash, jaundice and respiratory findings. Laboratory abnormalities included cerebrospinal fluid (CSF) pleocytosis, chest radiograph infiltrates, abnormal urinalyses and elevated transaminases. EVs were most commonly isolated from CSF and rectum/stool but also frequently from serum and urine. Five EV-infected patients had severe multisystem disease (pneumonitis, hepatitis, thrombocytopenia, bleeding and meningitis), requiring supportive care and lengthy hospitalizations. All survived, 2 with residual hepatic dysfunction. Markers of severe disease included: early age of illness onset (especially Day 1 of life); maternal viral symptoms at delivery; absence of fever and irritability; tachypnea; lethargy; abdominal distension; hepatomegaly; and positive serum viral culture. These data support conservative management of ill infants < or = 2 weeks of age and suggest that antiviral therapy for neonatal EV infection would be optimally targeted at infants with early onset illness, multisystem disease and/or viremia.

The Lelystad virus or one of two US isolates (VR2385, VR2431) of porcine reproductive and respiratory syndrome virus were given intranasally to 25 4-week-old cesarian-derived colostrum-deprived pigs. Pigs from these groups were necropsied at 1, 2, 3, 5, 7, 10, 15, 21, or 28 days postinoculation. The Lelystad virus and VR2431 induced mild transient pyrexia, dyspnea, and tachypnea. VR2385 induced labored and rapid abdominal respiration, pyrexia, lethargy, anorexia, and patchy dermal cyanosis. All three isolates induced multifocal tan-mottled consolidation involving 6.8% (n = 9; SEM = 3.4) of the lung for Lelystad, 9.7% (n = 9, SEM = 2.7) of the lung for VR2431, and 54.2% (n = 9, SEM = 4.4) of the lung for VR2385 at 10 days postinoculation. Characteristic microscopic lung lesions consisted of type 2 pneumocyte hypertrophy and hyperplasia, necrotic debris and increased mixed inflammatory cells in alveolar spaces, and alveolar septal infiltration with mononuclear cells. Lymphadenopathy with follicular hypertrophy, hyperplasia, and necrosis was consistently seen. Similar follicular lesions were also seen in Peyer's patches and tonsils. Lymphohistiocytic myocarditis and encephalitis were reproduced with all three isolates. Clinical respiratory disease and gross and microscopic lung lesion scores were considerably and significantly more severe in the VR2385-inoculated pigs. All three viruses were readily isolated from sera, lungs, and tonsils throughout the 28 days of the study. The lymphoid and respiratory systems have the most remarkable lesions and appear to be the major site of replication of these viruses. This work demonstrated a marked difference in pathogenicity of porcine reproductive and respiratory syndrome isolates.

Pigeon breeder's disease is a common form of hypersensitivity pneumonitis, which is rarely diagnosed in children. We report a seven year old boy, who developed cough, easy fatigue, anorexia and weight loss over a period of two months after having contact with pigeons. The findings on physical examination were tachypnoea and reduced thoracic movements. Chest radiograph showed widespread fine nodular shadowing in both lung fields. Pulmonary function tests demonstrated a restrictive defect and an impaired diffusion. Lymphocytes were highly increased in bronchoalveolar lavage (BAL) fluid. Precipitating antibodies against pigeon excreta was found in the serum. Environmental control of pigeon protein and a course of systemic corticosteroids over 4 months resulted in clinical and lung function improvement. However clinical recovery stopped over several months after discontinuation of steroid therapy. Therefore steroid therapy was reinstalled and continued until complete clinical recovery and pulmonary function occurred, that was 20 months after onset of the disease. Essential for the patient was to avoid further contact with birds. However a prolonged steroid therapy was necessary to achieve complete resolution. Lung function tests were useful for follow up and decisions on further treatment.

A 14-month-old shorthaired cat was presented to the Animal Hospital in Skara, Sweden, with a two-day history of lethargy, anorexia and tachypnoea. Clinical examination and laboratory investigations revealed fever, dehydration, tick infestation, neutrophilia with left shift, lymphopenia, hyperglycaemia and intracytoplasmic neutrophilic Ehrlichia inclusions. After treatment with intravenous doxycycline and lactated Ringer's solution the temperature returned to normal. Oral treatment with doxycycline continued for 20 days. The ehrlichiosis diagnosis was confirmed by serology, polymerase chain reaction and DNA sequencing. No relapse was observed during the eight-month follow-up period. The granulocytotropic Ehrlichia strain found in the cat was later characterised by analysis of the 16S rRNA gene sequence which showed 100 per cent identity to DNA sequences found in Swedish canine and equine granulocytotropic Ehrlichia strains. This is, to the best of the authors' knowledge, the first reported case of granulocytic ehrlichiosis in a cat.

A three-year-old weimaraner was presented with lethargy, anorexia, neck pain and a soft fluctuant swelling in the thoracic inlet. A cough had been noted previously. Clinical examination revealed tachycardia, tachypnoea, pallor and a large subcutaneous swelling, with bruising, suggestive of a haematoma in the thoracic inlet. Thoracic radiographs revealed a cranial mediastinal mass which had the ultrasonographic appearance of fluid, and there was also a marked generalised interstitial lung pattern. Routine haematology revealed severe anaemia and thrombocytopenia, although coagulation tests were within normal limits. A diagnosis of immune-mediated thrombocytopenia was however made on the basis of a positive antiplatelet antibody test and a rapid response to prednisolone therapy. Furthermore, a tentative diagnosis of Angiostrongylus vasorum infection was suggested on the basis of clinical and radiographic findings, although no lungworm larvae were identified on faecal analysis. Despite initiating treatment with fenbendazole, the dog died suddenly. Postmortem examination revealed myocarditis, thrombosing arteritis, pneumonia and chronic membranoproliferative glomerulonephritis associated with A vasorum infection.

An 8-year-old male rhesus monkey (Macaca mulatta) died following a 6-day illness consisting of progressive depression, anorexia, labored abdominal breathing, coughing, and tachypnea. Gross necropsy findings included severe multifocal (miliary) granulomatous pneumonia, granulomatous splenitis, and multifocal cerebral abscesses. Histologic examination revealed 10-15-microm broad-based budding organisms within pyogranulomatous inflammatory lesions in the lung, tracheobronchial lymph node, brain, spleen, and liver. The distribution of extrapulmonary lesions was intermediate between that described for dogs and that described for humans. These findings were consistent with blastomycosis, which is previously unreported in nonhuman primates.

Preparturient hypocalcemia was identified in 4 cats in a specific pathogen-free colony between 1995 and 1996. All cats had an acute onset of clinical signs, 3 to 17 days prior to parturition. Signs of depression, weakness, tachypnea, and mild muscle tremors were the most common clinical signs, following by vomiting and anorexia. Additional abnormalities included hypothermia, third eyelid prolapse, dehydration, pallor, lethargy, flaccid paralysis, and hyperexcitability. Hematologic abnormalities included leukocytosis with neutrophilia and lymphopenia. Hypocalcemia was documented in each queen. Common serum biochemical abnormalities included high aspartate aminotransferase and creatine kinase activities. All cats responded to IV or SC administration of 10% calcium gluconate. Queens were then given calcium orally prior to and following parturition. The queens did not have additional complications for the duration of the gestational or lactational periods.

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.
