Four hundred twenty-nine patients with bacterial meningitis were assigned on a nonselective alternating basis into one of two therapeutic regimens. Patients in Group I received dexamethasone in addition to standard antibacterial chemotherapy of ampicillin and chloramphenicol whereas those in Group II received antibacterial chemotherapy alone. Dexamethasone(More)
Coagglutination tests with Salmonella A, D, Vi, and polyvalent antiserum-sensitized staphylococcal cells were compared with conventional culture methods for detecting salmonellae in ox bile cultures of blood clots from enteric fever patients. The coagglutination tests appeared equally as effective as conventional subculture methods for detecting positive(More)
During a 5-year period, 280 of 2010 patients admitted to the meningitis ward of a referral hospital in Cairo, Egypt, were clinically diagnosed as having tuberculous meningitis and were treated with either antituberculous chemotherapy and dexamethasone or antituberculous chemotherapy alone. Fatality rates and neurologic sequelae were compared for the 2(More)
During a survey examining the causes of diarrhea in the East African country of Djibouti, 140 bacterial pathogens were recovered from 209 diarrheal and 100 control stools. The following pathogens were isolated at comparable frequencies from both diarrheal and control stools: enteroadherent Escherichia coli (EAEC) (10.6 versus 13%), enterotoxigenic E. coli(More)
The frequency-pulsed electron-capture gas-liquid chromatography technique described previously by Brooks et al. was modified and applied to the studies of coded and routine clinical specimens. Uncentrifuged cerebrospinal fluid (2 ml) was extracted under acidic conditions, derivatized, and analyzed by frequency-pulsed electron-capture gas-liquid(More)
It has previously been shown that Salmonella paratyphi A associates with adult Schistosoma mansoni worms in animal models and in patients with schistosomiasis, resulting in Salmonella infections that are difficult to manage unless the helminthic parasite is eliminated. In the present study, characteristics of this association were explored. In vitro, fresh(More)
A study was conducted of travelers' diarrhea in a United States military population on deployment in Cairo, Egypt, during July and August 1987. Acute diarrhea requiring medical attention developed in 183 (4%) of 4,500 troops. A possible etiologic agent was identified in 49% of all diarrhea cases. Enteric pathogens associated with cases of diarrhea included:(More)
The in vitro activity of ciprofloxacin against bacterial enteropathogens isolated from cases of travellers' diarrhea in Egypt was compared to trimethoprim (TMP) and trimethoprim-sulfamethoxazole (SXT). No resistance to ciprofloxacin was noted for any of the Campylobacter jejuni/coli, Shigella spp., and enterotoxigenic Escherichia coli strains examined.(More)
A total of 7,809 patients with meningitis or encephalitis were admitted to the Abbassia Fever Hospital in Cairo, Egypt from November 1, 1966 to April 30, 1989. The etiology was Neisseria meningitidis (mostly group A) in 27.3% of the patients, Mycobacterium tuberculosis in 19.7%, Streptococcus pneumoniae in 7.3%, and Haemophilus influenzae in 4.1%. Almost(More)
A controlled field trial was performed in Egypt to evaluate a whole cell typhoid vaccine prepared with a nonmotile mutant of S. typhi Ty2 (TNM1) devoid of flagellar antigen. This vaccine did not elicit an H antibody response, but significant Vi and O agglutinin responses were observed. There were 34 typhoid cases among 21 063 six- to seven-year-old children(More)
