Experimental infection of Red Sokoto goats with Salmonella typhimurium

Salmonella typhimurium infection was experimentally induced in goats by administering 2 x 10(10) organisms per os. The disease produced was characterized by pyrexia, diarrhoea and neutrophilia. One goat died from septicaemia. Somatic "0" agglutinins were detected 14 days post infection (p.i.). Excretion of organisms in faeces ceased by 6 weeks p.i. Goats which recovered from primary infection were refractory to a secondary challenge with 2 x 10(11) organisms. The results indicate that in the absence of signs of ill-health, the detection of neutrophilia and "0" agglutinins and isolation of Salmonella organisms from faeces mainly served as evidence of recent infection.
