Epidemic waves of cholera in the last two decades in Mozambique.

Introduction: Africa is increasingly affected by cholera. In Mozambique, cholera appeared in the early 1970s when the seventh pandemic entered Africa from the Indian subcontinent. In the following decades, several epidemics were registered in the country, the 1997-1999 epidemic being the most extended.

Molecular characterization of ICEVchVie0 and its disappearance in Vibrio cholerae O1 strains isolated in 2003 in Vietnam.

We analyzed 28 epidemic Vibrio cholerae O1 strains isolated in the region of Thua Thien Hue (Vietnam) in 2003. Ubiquitous amoxicillin, prevalent aminoglycosides and sporadic erythromycin resistances were observed. All were devoid of plasmids, class 1 integrons and ICEs and showed the same BglI ribotype, irrespective of their site of isolation and resistance pattern.

New cluster of plasmid-located class 1 integrons in Vibrio cholerae O1 and a dfrA15 cassette-containing integron in Vibrio parahaemolyticus isolated in Angola.

The resistance profile and its correlation with mobile genetic elements were investigated in 11 Vibrio cholerae O1 and 2 Vibrio parahaemolyticus clinical isolates, as well as in 1 V. cholerae O1 and 1 V. cholerae non-O1 environmental isolate, isolated between 1991 and 1996 in different provinces of Angola.

Pathogenic enteric Escherichia coli in children with and without diarrhea in Maputo, Mozambique.

A study was conducted on the circulation of potentially diarrheagenic Escherichia coli in two groups of children, both under the age of seven. The first group (548 children) suffered from mild diarrhea and attended the Xipamanine Health Center of Maputo, in Mozambique. The second group (380 children) included randomly chosen, asymptomatic, children from the same population.
