Two outbreaks of botulism in sheep and goats are described; in one, 329 out of 900 sheep in a feedlot died within 9 d of the onset of the disease and in the other, 100 sheep and goats out of 330 succumbed over a period of about 3 weeks. Animals were found dead or died suddenly, without exhibiting clinical signs. Others stood with lowered heads and showed drooling of saliva or a stiff gait. Paresis and/or paralysis were frequent signs in the terminal stages of the disease. Gross lesions such as the accumulation of fluids in body cavities, pulmonary oedema, foam in the trachea, epicardial haemorrhages and congestion of the mucosa of the small intestine, suggestive of heart failure, were present in animals from both outbreaks. Botulism was confirmed via the mouse toxicity test, by the demonstration of Type C and Type D toxins in the feed and intestinal contents of sheep from the first outbreak and Type D toxin in intestinal contents of sheep from the second. The clinical signs and macropathology in the outbreaks of botulism in sheep and goats in South Africa may resemble "krimpsiekte" and cardiac glycoside and ionophore poisoning, as well as other conditions causing heart failure.

Nemaline myopathy (NM) is a genetically and clinically heterogeneous muscle disorder, defined by the presence of characteristic nemaline bodies on muscle biopsy. The disease has a wide spectrum of phenotypes, ranging from forms with neonatal onset and fatal outcome to asymptomatic forms. The neonatal form is severe and usually fatal. The clinical variability, with differing age of onset and severity of symptoms makes the diagnosis difficult during infancy. There is no curative treatment. L-tyrosine may prevent aspiration by reducing pharyngeal secretions and drooling. Most of the patients die from respiratory and cardiac failure. This article discusses a newborn infant who presented with generalized weakness and respiratory failure. Partial response to L-tyrosine treatment was noted. The case is worth presenting to remind clinicians of congenital myopathies in the differential diagnosis of floppy infant during neonatal period and to emphasize the importance of muscle biopsy in diagnosis.
