the fimbriae-like structures on v. cholerae isolated in kenya. | for vibrio cholerae 01 to overcome the normal intestinal clearing mechanisms and facilitate colonization in the host gut, fine filamentous structures covering the surface of all the cell must exist. these fimbriae-like structures were investigated in this study. selection of the k23 v. cholerae 01 biotype el-tor isolated in kisumu, kenya, was based on its proteinase activity and ability to agglutinate 0.2m ammonium sulphate. this strain was cultured in modified tryptone broth ph 8.4, at 37 degre ... | 1992 | 1356750 |
the characterization of vibrio cholerae isolated in kenya in 1983. | a total of 245 strains of vibrio cholerae 01 and two strains of v. cholerae non-01 were isolated and collected from diarrhoeal patients in homa bay district hospital and the other medical facilities in nyanza province, kenya in 1983. the majority of v. cholerae 01 tested were ogawa type (with the exception of nine inaba type), biotype e1 tor (except one untypable strain) and celebes original type (except one cured type). haemolytic activity to sheep red blood cells was detected in 75.5% of isola ... | 1986 | 3795327 |
transmission of epidemic vibrio cholerae o1 in rural western kenya associated with drinking water from lake victoria: an environmental reservoir for cholera? | sub-saharan africa has the highest reported cholera incidence and mortality rates in the world. in 1997, a cholera epidemic occurred in western kenya. between june 1997 and march 1998, 14,275 cholera admissions to hospitals in nyanza province in western kenya were reported. there were 547 deaths (case fatality rate = 4%). of 31 vibrio cholerae o1 isolates tested, all but one were sensitive to tetracycline. we performed a case-control study among 61 cholera patients and age-, sex-, and clinic-mat ... | 1999 | 10072150 |
[cholera++ epidemic in kenya]. | a cholera epidemic in 1997 followed on the heels of the 1992 epidemic that claimed thousands of victims in kenya. this time, it emerged in the migori district near the tanzanian border, when a woman who had married in tanzania brought her five-month-old baby to visit her parents. the infant, who contracted serious diarrhea and vomiting, died before the mother could reach a dispensary. during the funeral, a perfect opportunity for the disease to spread, those attending observed the traditional ri ... | 1999 | 10362941 |
does water hyacinth on east african lakes promote cholera outbreaks? | cholera outbreaks continue to occur regularly in africa. cholera has been associated with proximity to lakes in east africa, and vibrio cholerae has been found experimentally to concentrate on the floating aquatic plant, water hyacinth, which is periodically widespread in east african lakes since the late 1980s. from 1994 to 2008, nyanza province, which is the kenyan province bordering lake victoria, accounted for a larger proportion of cholera cases than expected by its population size (38.7% o ... | 2010 | 20682884 |
prevalence of vibrio cholerae o1 el tor variant in a cholera-endemic zone of kenya. | since 2007, kenya has experienced an increase in cholera outbreaks characterized by a high fatality rate. in this study, we characterized 81 vibrio cholerae isolates from diarrhoeal stool samples in nyanza, a cholera-endemic lake region of kenya, for virulence properties, clonality and antibiotic susceptibility. eighty of these isolates were v. cholerae o1 el tor variants carrying the classical ctxb gene sequence, while one isolate was v. cholerae non-o1/o139. all of the el tor variants were of ... | 2014 | 24396087 |
