In the current study, 65 Vibrio spp. were isolated from the Monastir lagoon water, were characterized phenotypically and genotypically. In addition, we looked for the presence of three Vibrio parahaemolyticus virulence genes (tlh, trh and tdh) and ten Vibrio cholerae virulence genes (ctxA, vpi, zot, ace, toxR, toxT, tosS, toxRS, tcpA and cpP). We also investigated the antibiotic susceptibilitie...
Seasonal plankton blooms correlate with occurrence of cholera in Bangladesh, although the mechanism of how dormant Vibrio cholerae, enduring interepidemic period in biofilms and plankton, initiates seasonal cholera is not fully understood. In this study, laboratory microcosms prepared with estuarine Mathbaria water (MW) samples supported active growth of toxigenic V. cholerae O1 up to 7 weeks a...
Cholera has been reported in the state of Orissa, India during the past decades. An outbreak of diarrheal disease occurred during November 1 to November 9, 2000 in Rusipada village near Puri, which was inhabited by a population of approximately 560. During the outbreak, Vibrio cholerae O139 strains were isolated from clinical specimens collected from patients with acute diarrhea admitted to the...
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...
Recognizing cholera cases early, especially in the initial phase of an outbreak and in areas where cholera has not previously circulated, is a high public health priority. Laboratory capacity in such settings is often limited. To address this, we have developed a rapid diagnostic test (RDT) termed Cholkit that is based on an immunochromatographic lateral flow assay for the diagnosis of cholera ...
Currently, no cholera vaccine is available for persons traveling from the United States to areas of high cholera transmission and who for reasons of occupation or host factors are at increased risk for development of the disease. A single-dose oral cholera vaccine with a rapid onset of protection would be particularly useful for such travelers and might also be an adjunct control measure for ch...
BACKGROUND Vibrio cholerae non-O1/ non-O139 serogroups have been reported to cause sporadic diarrhoea in humans. Cholera toxins have been mostly implicated for hypersecretion of ions and water into the small intestine. Though most of the V. cholerae non-O1/ non-O139 strains lack these cholera toxins, several other innate virulence factors contribute towards their pathogenicity. The environmenta...
