145. Intestinal Atresia and Ectopia in a Bovine Fetus.

Author

Lejeune, B., Miclard, J., Stoffel, M. H., and Meylan, M.

Abstract

The article describes a unique form of intestinal atresia with extrafetal ectopia in a Red Holstein cow presented with uterine torsion at 235 days of pregnancy. Information on segmental anomalies of the bovine intestine is provided along with genetic factors that may be involved in the etiopathogenesis of intestinal atresia. The case history is presented including the results of the physical examination and laparotomy that led to the dam and fetus being euthanatized. Necropsy findings are discussed which combined malformation with ectopia and atresia.

Abstract

Background: Infection with Mycobacterium microti can cause chronic disease in animals and threaten human health through its zoonotic potential. Objective: To describe clinical findings, diagnostic investigations, necropsy, and epidemiology results in South American camelids (SAC) infected with M. microti, member of the Mycobacterium tuberculosis complex. Animals: Eleven SAC with tuberculous lesions. Methods: Description of 10 llamas and 1 alpaca, aged 4–18 years, from 6 herds with a history of wasting and weakness admitted to the Vetsuisse-Faculty of Berne over 8 years. Results: Clinical signs included weight loss, recumbency, and anorexia in late stages of the disease. Respiratory problems were seen in 6 animals of 11. No consistent hematologic abnormalities were identified. Suspect animals were examined in detail by abdominal ultrasonography and thoracic radiology. Abnormal findings such as enlarged mediastinal, mesenteric, or hepatic lymph nodes were seen only in animals with advanced disease. Single comparative intradermal tuberculin test with bovine protein purified derivate (PPD) and avian PPD was negative in all animals. At necropsy, typical tuberculous lesions were found, and confirmed by bacteriological smear and culture, molecular methods, or both. Conclusions and Clinical Importance: Infection caused by M. microti should be considered a differential diagnosis in chronic debilitating disease with or without respiratory signs in SAC. Antemortem confirmation of the diagnosis remains challenging at any stage of infection. Because cases of M. microti infection have been reported in immunocompromized human patients, the zoonotic potential of the organism should be kept in mind when dealing with this disease in SAC.

Abstract

The prevalences of Ciyptosporidium parvum, rotavirus, bovine coronavirus (BCV), and enterotoxigenic Escherichia coil (E coil K99) were determined in diarrhoeic dairy calves aged one to 21 days on 71 dairy farms in western Switzerland during the winter of 2005 to 2006. Faecal samples from 147 untreated calves suffering from acute diarrhoea were analysed by standardised diagnostic methods, and the immunoglobulin status of each calf was evaluated. The prevalences of C parvum, rotavirus, BCV and E coil K99 were 55·O per cent, 58·7 per cent, 7·8 per cent and 5·5 per cent, respectively. The proportions of herds positive for the respective pathogens among the herds with diarrhoeic calves were 41·7 per cent, 52·1 per cent, 2·1 per cent and 2·1 per cent. The immunoglobulin concentration in the serum of 90·5 per cent of the diarrhoeic calves was below 8 g/l. [ABSTRACT FROM AUTHOR]
