Antibiotic-Multiresistant Salmonella typhi in Egypt. (Reannouncement with New Availability Information).

摘要

Salmonella typhi resistant to one or more antibiotics has been reported. In 1981 we reported the appearance of a chloramphenicol-resistant strain of S. typhi isolated from the stool of a patient with typhoid fever in Upper Egypt (Sippel et al., 1981). During the past 10 years, we have isolated over a thousand strains of S. typhi from blood and other specimens from patients with typhoid fever and meningitis. All strains were susceptible to ampicillin, chloramphenicol, trimethoprim/sulfamethoxazole and other antibiotics as determined by the disc diffusion method. On 7 June 1988 we isolated S. typhi from the blood of a patient with typhoid fever. This strain was identified by the API-20E commercial system and confirmed by serotyping using MinESS antisera (Difco); it demonstrated the presence of O, H, and Vi antigens.
