BACKGROUND Mozambique suffers recurrent annual cholera outbreaks especially during the rainy season between October to March. The African Cholera Surveillance Network (Africhol) was implemented in Mozambique in 2011 to generate accurate detailed surveillance data to support appropriate interventions for cholera control and prevention in the country. METHODOLOGY/PRINCIPAL FINDINGS Africhol was...
BACKGROUND The quality of drinking water has an important role in human infection and disease. This study was aimed at comparing polymerase chain reaction and culture in detecting Escherichia coli, Salmonella species and Vibrio cholera in tape water and bottled drinking water in various seasons in Isfahan province, Iran. METHODS A total of 448 water samples from tap water and bottled mineral ...
BACKGROUND Since cholera appeared in Africa during the 1970s, cases have been reported on the continent every year. In Sub-Saharan Africa, cholera outbreaks primarily cluster at certain hotspots including the African Great Lakes Region and West Africa. METHODOLOGY/PRINCIPAL FINDINGS In this study, we applied MLVA (Multi-Locus Variable Number Tandem Repeat Analysis) typing of 337 Vibrio choler...
24 Vibrio cholerae serotype O1 causes diarrhea in many developing countries around the world. In most cases, cholera patients pose some sorts of immunity against the naturally occurring infection. In the present study, the bactericidal activity of the sera of rabbit immunized with whole cell extract of Vibrio cholerae O1 was investigated. The protein profile of the serotype exhibited 20 types o...
We have constructed an overexpression system in which the gene encoding the B subunit of cholera toxin (CTB) was placed under the control of the strong tacP promoter in a wide host range plasmid. Recombinant nontoxigenic classical and E1 Tor Vibrio cholerae strains of different serotypes harboring this plasmid excreted 10- to 100-fold higher amounts of CTB than any other wild-type or recombinan...
OBJECTIVE To study the drug sensitivity pattern of cholera in children. SETTING DTU of Civil Hospital, Karachi. PATIENTS AND METHODS All children age 2 months to 15 years attending Diarrhoea Treatment Unit (DTU) with acute onset of diarrhoea and dehydration were screened for cholera. Stool samples were collected in alkaline peptone and those positive for cholera had their antibiotic sensiti...
Tomb and Maitra (1926) as a result of their investigations concluded that the agglutinable vibrio found in the dejecta of cholera patients, and the non-agglutinable vibrio found in carriers and in natural waters contaminated with human faeces are one and the same organism. They arrived at this conclusion after inseminating tanks* with fresh cholera stools containing large numbers of agglutinabl...
BACKGROUND Cholera is an ancient disease that continues to cause epidemic and pandemic disease despite ongoing efforts to limit its spread. Mathematical models provide one means of assessing the utility of various proposed interventions. However, cholera models that have been developed to date have had limitations, suggesting that there are basic elements of cholera transmission that we still d...
Cholera is a contagious acute diarrheal disease due to ingestion of contaminated water and food with Vibrio cholera, Gram-negative bacterium that naturally inhabits coastal estuarine ecosystems. Millions cholera cases thousands deaths are annually reported worldwide. endemic in Iraq every 3-5 years interval. Meanwhile, outbreaks have been reporting Kurdistan region. However, the epidemiology ha...
Toxin-coregulated pilin A (TcpA) is the main structural subunit of a type IV bundle-forming pilus of Vibrio cholerae, the cause of cholera. Toxin-coregulated pilus is involved in formation of microcolonies of V. cholerae at the intestinal surface, and strains of V. cholerae deficient in TcpA are attenuated and unable to colonize intestinal surfaces. Anti-TcpA immunity is common in humans recove...
