Chronic disease may cause pancytopenia, uveitis, glomerulonephritis and neurological signs. <b>Diagnosis:</b> CBC and smear (morulae are insensitive); platelet count is commonly low. Use serology such as IFA/ELISA (including SNAP) plus PCR, ideally before treatment. Assess chemistry, urinalysis and coagulation where bleeding/renal involvement occurs. <b>Treatment:</b> doxycycline 10 mg/kg PO q24h or 5 mg/kg q12h for 28 days is standard.

Scientific reasons [3]','1 Sea water is hypertonic: it draws fluid into alveoli/interstitium and can cause pulmonary oedema. 2 Large trees increase lightning-strike risk; animals should be moved to safe enclosed shelter. 3 Tracheal sounds are louder because turbulent airflow is transmitted directly through a large central airway. 4 Anthrax carcasses are not opened because oxygen exposure allows sporulation and environmental persistence. 5 Colostrum provides maternal antibodies and is the most important protection against neonatal colibacillosis. 6 Creatinine is generally a more specific filtration marker than BUN, which varies with diet, GI bleeding and hydration.') st += [PageBreak()] # paper 3 st += [p('PAPER III: OCTOBER 2025','H1x'),p('SECTION A','H1x')] st += Q('Q1(A).

Anthrax in a 400 kg cow: etiology, findings, diagnosis and treatment [4]','Cause and epidemiology are as above. In cattle, peracute death, high fever, collapse and dark unclotted bleeding from natural openings are key. Do not perform postmortem. Submit peripheral blood smear/PCR via authorized channels, notify and quarantine. In early live cases, penicillin or oxytetracycline may be used under official veterinary direction; treat contacts according to local authority policy.

EPI in dog: investigation and treatment [4]','History of weight loss, polyphagia and large pale malodorous stools suggests EPI. Perform CBC/biochemistry, faecal parasite assessment and serum canine TLI; cTLI ≤5.5 µg/L is diagnostic. Measure cobalamin and folate and investigate concurrent pancreatitis/intestinal disease.

Enterotoxaemia in goats [4]','Usually caused by <i>C. perfringens</i> type D producing epsilon toxin, often after sudden access to high-carbohydrate feed/milk or lush pasture. Rapid deaths, abdominal pain, diarrhoea, neurological signs, opisthotonos/convulsions and sudden collapse may occur; kids are commonly affected. Diagnosis is based on history, lesions, intestinal toxin testing and exclusion of other causes; postmortem may show pulpy kidneys but this is not always present.
