Vibrio cholerae is an autochthonous inhabitant of riverine and estuarine environments and also is a facultative pathogen for humans. Genotyping can be useful in assessing the risk of contracting cholera, intestinal, or extraintestinal infections via drinking water and/or seafood. In this study, environmental isolates of V. cholerae were examined for the presence of ctxA, hlyA, ompU, stn/sto, tc...
BACKGROUND & OBJECTIVES El Tor Vibrio cholerae O1 carrying ctxB C trait, so-called El Tor variant that causes more severe symptoms than the prototype El Tor strain, first detected in Bangladesh was later shown to have emerged in India in 1992. Subsequently, similar V. cholerae strains were isolated in other countries in Asia and Africa. Thus, it was of interest to investigate the characteristic...
There was an inexplicable upsurge in the incidence of non-O1, non-O139 Vibrio cholerae among hospitalized patients admitted to the Infectious Diseases Hospital, Calcutta, India, between February and March 1996. Of the 18 strains of V. cholerae isolated during this period, 15 belonged to the non-O1, non-O139 serogroups (4 belonged to O144, 3 belonged to O11, 1 each belonged to O6, O8, O12, O19, ...
The aerobic oral and cloacal bacterial microbiota and their antimicrobial resistance were characterized for 64 apparently healthy sea turtles captured at their foraging grounds in Ojo de Liebre Lagoon (OLL), Baja California Sur (BCS), Mexico (Pacific Ocean) and the lagoon system of Navachiste (LSN) and Marine Area of Influence (MAI), Guasave, Sinaloa (Gulf of California). A total of 34 black tu...
Frans Oort \Een zot kan meer vragen \One fool can ask more questions dan tien wijzen kunnen beantwoorden." than ten wise men can answer." Een oud Nederlands spreekwoord. An old Dutch saying. Introduction In June 1995 several mathematicians will gather in Utrecht for a conference on \Arithmetic and geometry of abelian varieties," and this seems a good occasion to share with them some of the ques...
مقدمه: ویبریو کلرا (عامل بیماری وبا) یک پاتوژن مهم در بروز بیماری اسهال در بخش های گسترده ای از آسیا و آفریقا است. این باکتری یک پاتوژن روده ای است که می تواند سبب بروز بیماری همه گیر گردد. درنتیجه تشخیص سریع، حساس و اختصاصی ویبریو کلرا، مورد توجه اکثر آزمایشگاه های تشخیصی است. هدف از این پژوهش، طراحی و توسعه یک روش سنجش سریع ژنوم باکتری ویبریو کلرا بر اساس واکنش زنجیره ای پلیمراز شش گانه (hexa...
Mild, non-acidic cordons used in the n~-~u~us ~~~~ of a 2-~o~n~~~e nu&uside with t-butyi nitrite gave an unexpected ~~~~~~-2~e nuckoside which was not formed when primary a&y1 nitrites were used. The isolated compounds were evaluated for activity against herpesviruses and for cytotoxicity against human foreskin fibroblast cells. Benzimidazoles have demonstrated widespread biological activity ra...
BACKGROUND Cholera has been endemic in Douala, since 1971 when it was first recorded in Cameroon. Outbreaks have often started in slum areas of the city including New Bell. Despite the devastating nature of outbreaks, always resulting in high mortality and morbidity, a paucity of information exists on the reservoirs of the causative agent, V. cholerae, and factors maintaining its persistence. T...
The emergence of Vibrio cholerae O139 Bengal in 1993, its rapid spread in an epidemic form, in which it replaced existing strains of V. cholerae O1 during 1992 and 1993, and the subsequent reemergence of V. cholerae O1 of the El Tor biotype in Bangladesh since 1994 have raised questions regarding the origin of the reemerged El Tor vibrios. We studied 50 El Tor vibrio strains isolated in Banglad...
