Detection of gyrA mutation among clinical isolates of Campylobacter jejuni isolated in Egypt by MAMA-PCR.

Introduction: Campylobacter spp are the major cause of enteritis in humans and more than 90% of reported infections are caused by Campylobacter jejuni. Fluoroquinolones such as ciprofloxacin are the antibiotics of choice for treatment. An increase in the frequency of ciprofloxacin-resistant Campylobacter has been reported globally due to a single base mutation (C-257 to T) in codon 86 of the quinolone resistance determining region (QRDR) of the gyrA gene altering the amino acid sequence from threonine at position 86 to isoleucine (Thr-86 to Ile).

Isolation of cryptococcus, Candida, Aspergillus, Rhodotorula and nocardia from meningitis patients in egypt.

Meningitis occurs throughout Egypt and is largely attributed to bacterial pathogens, but there is little information on fungal etiologies of meningitis. We, therefore, investigated fungal infections among Egyptian patients with acute and subacute meningitis who tested negative for bacterial and viral agents. A total of 1000 cerebrospinal fluid (CSF) samples collected from nine governorates of Egypt during 1998-2002 were initially stained with Gram's, India ink, and lacto-phenol cotton-blue stains, and examined under light microscope to detect fungal elements.

Concurrent infections in acute febrile illness patients in Egypt.

We report the occurrence of concurrent infections with multiple acute febrile illness (AFI) pathogens during an ongoing prospective laboratory-based surveillance in four infectious disease hospitals in urban and rural areas of Egypt from June 2005 to August 2006. Patients were screened for Leptospira, Rickettsia typhi, Brucella, or Salmonella enterica serogroup Typhi by various methods including serology, culture, and PCR. One hundred eighty-seven of 1,510 patients (12.

Retrospective serosurvey of leptospirosis among patients with acute febrile illness and hepatitis in Egypt.

The epidemiologic status of leptospirosis in Egypt has not been well defined because of difficulties in disease diagnosis. A retrospective study was conducted to detect leptospiral antibodies among undiagnosed acute febrile illness (AFI) and hepatitis cases. Approximately 16% of both AFI (141/886) and acute hepatitis (63/392) cases showed seroreactivity to Leptospira IgM by ELISA and microscopic agglutination test (MAT).

Etiology, antimicrobial susceptibility profiles, and mortality associated with bacterial meningitis among children in Egypt.

Purpose: Surveillance for patients with meningitis is a high priority in order to determine the etiology of disease and design prevention strategies. This study presents data on the causes of bacterial meningitis among children <6 years of age treated in a network of hospitals throughout Egypt.

Methods: Training was provided to standardize the collection of clinical information and optimize recovery of bacterial pathogens.

Trends of multiple-drug resistance among Salmonella serotype Typhi isolates during a 14-year period in Egypt.

A total of 853 isolates of Salmonella serotype Typhi recovered from patients with typhoid fever who were admitted to a major infectious disease hospital in Cairo, Egypt, from 1987 through 2000 underwent antibiotic susceptibility testing to determine multiple-drug resistance. The observed resurgence of chloramphenicol susceptibility (P=.002) may suggest reuse of this drug for the treatment of typhoid fever in Egypt.

Evaluation of dipstick serologic tests for diagnosis of brucellosis and typhoid Fever in egypt.

Two dipstick assays for the detection of Brucella- and typhoid-specific immunoglobulin M, recently developed by the Royal Tropical Institute of The Netherlands, were evaluated by use of 85 plasma samples from Egyptian patients. Both dipsticks were simple and accurate rapid diagnostic assays, and they can be useful adjuncts for the diagnosis of typhoid fever and brucellosis.
