During the period July, 1980 to June, 1981, 618 samples consisting of mesenteric lymph nodes, spleens and feces, collected from 307 sheep and goats slaughtered in the Riyadh Public Abattoir, were examined for salmonellae. Salmonellae were recovered from 14.7% of 307 lymph nodes, 4.7% of 192 feces and from 0.8% of 119 spleens. Among the 23 serotypes recovered, the most common was Salmonella typhimurium followed by S. newport, S. havana, S. bovismorbificans, S. reading, S. braenderup, S. eastbourne, and S. poona. Other less common serotypes were also encountered. Lymph nodes and feces from slaughtered animals may be a source for contamination of the red meat and other edible parts of the carcase with salmonellae. Consumption of contaminated meat or meat products either raw or undercooked may cause Salmonella food poisoning in man.

The suitability of a radiometric culture medium consisting of BACTEC 12B with PANTA PLUS, mycobactin J, and egg yolk was evaluated for detection of Mycobacterium paratuberculosis in feces, mesenteric lymph nodes, and intestinal walls from cattle, sheep, and goats. In addition, a simple method that would enable the rapid identification of Mycobacterium paratuberculosis by IS900 PCR in the primary cultures was sought so that subculture to secondary egg-free radiometric medium could be avoided. An ethanol extraction followed by differential centrifugation was used to separate M. paratuberculosis from PCR inhibitors in the primary culture. PCR was then undertaken with the pellet, after boiling to lyse the mycobacteria; if this test was negative, the DNA in the lysate was purified with guanidine thiocyanate and silica. Cultures of feces, ilea, and mesenteric lymph nodes from cattle, sheep, and goats known to have or suspected of having Johne’s disease yielded positive PCR results 1 to 7 weeks after inoculation. Similar results were obtained with soil and pasture samples that had been spiked withM. paratuberculosis. The results suggested that radiometric culture was more sensitive than histopathology in detectingM. paratuberculosis infection in sheep and goats and more sensitive than culture on Herrold’s egg yolk medium for the detection of the infection in cattle. Of 259 individual PCR tests with samples from cultures with growth indices of ≥10,237 (91.5%) were positive, with only 28 (11.8%) requiring both ethanol and silica preparation to yield a positive result. Of the 22 negative PCR results for samples from cultures with growth indices of ≥10, 18 were for samples from cultures that had only just developed evidence of growth. PCR-positive cultures tended to remain PCR positive over successive weeks. Flexibility in the timing of the sampling for PCR is thus possible, facilitating batch processing of samples in large-scale disease control programs for ruminants.

SUMMARYTo find out the salmonella carrier rate, 1980 samples comprising faeces, mesenteric lymph nodes, liver and spleen were collected from 812 sheep and 683 goats slaughtered for food. In all 72 salmonella strains from 51 animals (25 sheep and 26 goats) were isolated. These represented 22 salmonella serotypes. The public health significance of these findings is discussed.

A systemic study was done on the pathogenesis of experimentally induced Salmonella typhimurium infection in calves. The present investigation was carried out on sixteen normal colostrum fed friesian calves, ranging in age from 3 to 6 weeks. The calves were divided into two equal groups. Group I inoculated orally with (1.5 x 10'') Salmonella typhimurium and group IA served as control.  • The early ultrastructural alteration in the mesenteric lymph nodes was the presence of many free Salmonella in localized vacuoles. The interaction between the host cells and phagocytized Salmonella was also observed.
