Effect of Experimental Yolk Sac Infection with Escherichia Coli on Immune Status of Broiler Chicks
In this study, 100 day-old broiler chicks were divided into two groups, A and B containing 50 birds each. Experimental infection with E. coli was given intra yolk to group A on day-1 of experiment, while group B was kept as control. Parameters studied were examination of yolk sac, yolk sac:body weight ratio, antibody titer against Newcastle disease virus (NDV) and analysis of fractional serum p...
متن کاملExperimental infection of young chicks with attaching and effacing Escherichia coli.
Young chicks were inoculated with six different strains of attaching and effacing Escherichia coli isolated from the feces of calves, pigs, chicks, and humans. Colibacilli of some serotypes had colonized the cecum of chicks by 7 days after inoculation. The characteristic lesions associated with bacterial attachment were also seen on the mucosal surface of the cecum. Electron microscopy revealed...

more frequently in the spring and the fall, and a relationship to temperature or to changes in temperature may be involved (unpublished observations, Kaufman HE, 1981; Barren BA, 1994). The appearance of fever blisters and clinical herpes during temperature stress in hudans is a well-known clinical phenomenon. Our primate model may provide a way to study this relationship in a laboratory settin...
متن کاملObservations on experimental pneumococcal infection of the rabbit's cornea and on their treatment with penicillin.
T'HE experimental production of infected lesions of the rabbit's cornea by intra-corneal inoculation of suspensions of pneumococci has been described by Ginsberg and Kaufman (1913) and by Robson and Scott (1943a, b). Cole, Hamilton-Paterson and Sorsby (1945) were unable to confirm the findings of Robson and Scott, although they used the same strain of pneumococcus. This divergence of results ha...
متن کاملRole of EspB in experimental human enteropathogenic Escherichia coli infection.
Enteropathogenic Escherichia coli (EPEC), a leading cause of diarrhea among infants in developing countries, induces dramatic alterations in host cell architecture that depend on a type III secretion system. EspB, one of the proteins secreted and translocated to the host cytoplasm via this system, is required for numerous alterations in host cell structure and function. To determine the role of...
