An Abattoir Survey of Diseases of Feral Goats

Abstract

Caseous lymphadenitis was the most frequently encountered pathological condition in 3,720 feral goats examined during routine meat inspection procedures. Among 9 separate consignments of animals, the prevalence of infection averaged 7.4% (range 0.3% to 18.8%). The majority of lesions were seen in lymph nodes draining superficial body areas although many also occurred in internal nodes and organs. Corynebacterium ovis was isolated from 25 of 32 lesions submitted for bacteriological examination. Other conditions regularly encountered included pneumonia, cysticercosis, sarcosporidiosis and lice infestation, while myonecrosis, pleurisy, pericarditis, nephritis, hepatitis, cirrhosis and mite infestation were only occasionally found. A total of 171 serum samples were collected and tested against 17 antigens. Samples from 57.9% and 51.5% of goats showed positive serological reactions to the antigens for sarcosporidiosis and Q fever respectively.

An abattoir survey of the prevalence of caseous lymphadenitis in feral goats in Western Australia

“…The distribution of lesions in our survey was similar to that reported by Hein and Cargill (1981). Most abscesses (61%) were found only in superficial lymph nodes, predominantly the superficial cervical lymph nodes.…”

“…The prevalence of caseous lymphadenitis determined by the presence of lesions was 3.1% (range of 1.8% to 3.3% Hein and Cargill 1981).…”

“…Murdoch University, V . M. ANDERSON* Murdoch, M. E. NAIRN Western Australia 6150 A survey of Western Australian feral goats, processed through an export abattoir, was undertaken to correlate the prevalence of caseous lymphadenitis in this state with those encountered in previous surveys of feral goats from Queensland (McKenzie et al 1979), New South Wales and South Australia (Hein and Cargill 1981;Williams 1978).…”

Brain and lung cryptococcoma and concurrent corynebacterium pseudotuberculosis infection in a goat: a case report

“…Furthermore, visceral lesions have been described as rare and found only in a minority of animals (7). Additionally, in sheep, visceral lesions, and particularly lung lesions, occur more frequently and in greater numbers than in goats (6,7,10,11). Herein, it seems that primary infection with C.…”

Evaluation of the risk factors influencing the spread of caseous lymphadenitis in goat herds

“…Epidemiological studies carried out in other countries have usually been limited to the disease detection (Connor et al 2000, Chirino-Zarraga et al 2006. Some disease surveys were based on such small samples that results could not be considered reliable (Hein andCargill 1981, Batey 1986). …”
