BACTERIAL CONJUNCTIVITIS IN ZAHEDAN

Out of 495 patients who referred to the Zahedan Eye Clinic from May 22, 199 1 to October 22, 1992,296 cases were diagnosed as nonbacterial conjunctivitis.

Vi phage-host interaction in Salmonella typhosa.

Since their discovery by Craigie and Yen (1938), the Vi typing phages have been extensively employed in the study of the epidemiology of typhoid fever. Susceptibility to these phages is related to the presence of the Vi antigen, a component found in almost all freshly isolated typhoid cultures. The specific typing preparations, which produce confluent lysis with their homologous typhoid strains...

Chloramphenicol-resistant strains of Salmonella typhosa.

Changes that occur in gram-positive organisms coincident to the acquisition of resistance to such antibiotics as penicillin, streptomycin, and aureomycin are well documented (Gezon, 1948; Gezon and Cryst, 1948; Gezon and Fasan, 1950; Ramsey and Padron, 1954). However, with the exception of studies with Escherichia coli (Coffey et al., 1950; Bergersen, 1953) the changes in such gram-negative ent...
