A CELLULAR BASIS OF IMMUNITY IN EXPERIMENTAL BRUCELLA INFECTION

A Cellular Basis of Immunity in Experimental Brucella Infection

Brucella suis, Brucella abortus, and Brucella melitensis were shown by microscopic and cultural procedures to multiply extensively within normal rat, mouse, and guinea pig monocytes maintained in vitro in cell cultures for 3 days. Intracellular growth of brucellae had no observable toxic effects on most monocytes, although many of the cells became completely engorged with brucellae within 3 day...

effect of experimental coccidial infection on cellular immunity induced by newcastle disease vaccination in broilers

in order to evaluate the possible immunosuppressive effects of coccidial infection on cell mediated immunity (cmi) of broiler chickens, 640 ross male day old broiler chicks were randomly divided into 4 equal groups of 160 (each consist of 4 replicates of 40). the negative control group remained unchallenged, while the other three groups challenged with 3 different levels of high, medium and low...

Infection-immunity in Experimental Salmonellosis

Salmonella enteritidis is highly virulent for the mouse causing an infection resembling mouse typhoid. Survivors of the infection are completely resistant to reinfection and eliminate a large challenge dose of virulent organisms within 72 hr. The antigenically related Salmonella gallinarum was almost avirulent for the mouse but animals vaccinated with this organism were equally capable of elimi...
