materials and methods from 2004 to 2005, plants were collected from various ecological niches and the roots were used to isolate v. cholera. standard bacteriological, biochemical and serological tests were used for its typification. results in five out of the nine ecological niches explored, we collected either l. minor or e. crassipens, as these specimens cohabited only in two niches. v. chole...
In our investigation, rabbit hyper-immune serum to V.cholerae ogawa was absorbed with V.cholerae inaba whole-cells and vice versa. Applying ammonium sulphate precipitation method, mono-specific g globulins were purified and concentrated from the absorbed whole serum. These antibodies were fixed on staphylococcus cowan 1 NCTC-8325 whole-cells, using different chemical fixatives. It was observed ...
Cholera outbreak is more common in developing countries. The causative agent of the disease is Vibrio cholerae strains O1 and O139. Traditional diagnostic testing for Vibrio is not always reliable, because Vibrio can enter a viable but non cultivable state. Therefore, nucleic acid-based tests have emerged as a useful alternative to traditional enrichment testing. In this investigation, a...
OBJECTIVES An effective vaccine against cholera has been used for public health purposes in Vietnam since the 1990s. This vaccine was reformulated to meet WHO requirements. We assessed the safety and immunogenicity of the reformulated bivalent (Vibrio cholerae 01 and 0139) killed whole cell oral vaccine in a cholera endemic area in Kolkata, India. DESIGN Double-blind, randomized, placebo cont...
We report the synthesis of a series of bivalent 1,2,3-triazole linked galactopyranosides as potential inhibitors of cholera toxin (CT). The inhibitory activity of the bivalent series was examined (ELISA) and the series showed low inhibitory activity (millimolar IC(50)s). Conversely, the monomeric galactotriazole analogues were strong inhibitors of cholera toxin (IC(50) = 71-75 μM).
Abstract Background and objectives: Vibrio Cholera is one of the causative agents that can easily lead to death if the appropriate therapeutic measures are not taken in time. The purpose of this study is to identify the antibiotic sensitivity of the isolated V. choleras from the patients during the outbreak of Cholera in Golestan province, 2005. Materials and Methods: The Subjects were 97 posit...
Background: Cholera disease caused by Vibrio cholerae remains a major cause of morbidity and mortality throughout the world. Various strategies with different proteins as immunogens have been tried for vaccine development, none of which have been sufficiently effective to preclude cholera. Chimeric proteins, with their ability to present multiple antigens at the same time, can play important ro...
The origin of cholera has been elusive, even though scientific evidence clearly shows it is a waterborne disease. However, standard bacteriological procedures for isolation of the cholera vibrio from environmental samples, including water, between epidemics generally were unsuccessful. Vibrio cholerae, a marine vibrio, requiring salt for growth, enters into a dormant, viable but nonculturable s...
Cholera is an epidemic disease and a real public health problem throughout the world, particularly in West Africa. This study provides comprehensive overview of pathogenicity, epidemiology Vibrio cholerae strains’s antibiotics resistance A literature review was conducted online English using keywords “Cholera”, “Vibrio cholerae” “West Africa”, “Epidemiology”, “Antibiotic resistance”. These were...
conclusions our findings suggested a worrying increase in resistance of v. cholerae strains to commonly used antibiotics. differences in patterns of resistance between afghan and iranian patients' samples were observed, which further emphasize a need for constant observation. results a st revealed high levels of resistance to sulfamethoxazole-trimethoprim (89.6%), tetracycline (60.4%), ampicill...
