In recent years, emerging trend of antibiotic resistance in Vibrio cholerae associated with cholera epidemics is a matter of serious concern for the management of the disease. Indiscriminate use of antibiotics generally results in selection of antibiotic resistant strains. Introduction of newer antibiotics is a challenging task for the researchers as bacteria soon attain resistance. Therefore, identifying natural compounds of medicinal importance for control of cholera would be the best alternative. Garlic (Allium sativum) was recognised for many centuries in early Chinese, Egyptian and Indian civilisations as an herbal or traditional medicine. In present study, garlic was selected for screening of antimicrobial efficacy against V. cholerae. A total of 55 V. cholerae strains isolated from various outbreaks/epidemics were subjected to antimicrobial testing as per CLSI, USA 2010 guidelines. Antimicrobial screening of garlic extract was performed against all the multidrug resistant strains of V. cholerae. The garlic extracts showed antibacterial activity against all the V. cholerae strains tested, irrespective of their origin, multidrug resistance and virulence. Antibacterial efficacy of garlic on V. cholerae was also evident from in vivo study on sealed adult mice model. Thus, the Garlic extract harnesses the potential to control infection of multidrug resistant V. cholerae, especially in outbreak like situations in remote and under developed areas where drug supply itself is a challenge

Vibrio Cholerae O1

The in vivo production of soluble inorganic pyrophosphatases (PPases) was investigated in two strains, namely, Vibrio cholerae EM 004 (environmental strain) and Vibrio cholerae O1 757 (ATCC strain). V. cholerae is known to contain both family I and family II PPase coding sequences. The production of family I and family II PPases were determined by measuring the enzyme activity in cell extracts. The effects of pH, temperature, salinity of the growth medium on the production of soluble PPases were studied. In case of family I PPase, V. cholerae EM 004 gave the highest specific activity at pH 9.0, with 2% NaCl + 0.011% NaF and at 37°C. The strain V. cholerae O1 757 gave the highest specific activity at pH 9.0, with media containing 0% NaCl and at 37°C. On the other hand, under all the conditions family II PPase did not give any significant specific activity, suggesting that the family II PPase was not produced in vivo in either strains of V. cholerae under different experimental conditions.

No período de 1992 a 1994, foram analisadas 2.585 amostras de águas de diferentes ecossistemas, acrescidas de 91 espécimens de alimentos visando ao monitoramento de Vibrio cholerae O1 no Estado de Pernambuco. Nas 2.676 amostras foram detectadas 193 cepas de Vibrio cholerae O1 (7,21%) com predominância do sorovar Inaba (183-94,8%) sobre Ogawa (10-5,1%), todas classificadas no biotipo El Tor e sensíveis à tetraciclina. Numa parcela de setenta amostras selecionadas ao acaso, mas incluindo todas do sorovar Ogawa, foi evidenciada a produção de toxina colérica. A maior incidência do vibrião colérico em águas de rios, canais e de esgoto, representando 86% dos isolados, indicou a contaminação fecal por excretores como a causa preponderante na disseminação da bactéria nos sistemas aquáticos. Assinala-se a discreta ocorrrência de V. cholerae O1 nos alimentos processados (2,1%).
