Recent evidence supports the hypothesis that fish and waterbirds may also be intermediate reservoirs and vectors of V. cholerae (Halpern et al., 2008; Halpern and Izhaki, 2010).

By continuing you agree to the use of cookies. Vibrio cholerae, the causing agent of cholera is ubiquitous in marine and freshwater aquatic environments. Copepods (Crustacean) (Colwell and Huq, 2001) and chironomids (Diptera; Chironomidae) (Broza and Halpern, 2001; Halpern et al., 2004, 2006, 2007; Senderovich et al., 2008; Halpern and Senderovich, 2015) were described as natural reservoirs of V. cholerae. Active factors are shown in black, inactivate (repressed) factors are depicted in gray. Vibrio cholerae is a curved, Gram-negative bacilli. Table 1. Kaper, J. Phosphorylated LuxO, together with the alternative sigma factor σ54, promotes the expression of four homologous sRNAs, called Qrr1–4 (Lenz et al., 2004). Vibrio cholerae is a gram-negative, comma-shaped rod belonging to the family Vibrionaceae. In V. cholerae, two AIs, i.e., CAI-1 ((S)-3-hydroxytridecan-4-one) and AI-2 ((2S,4S)-2-methyl-2,3,3,4-tetrahydroxytetrahydrofuran borate), have been extensively studied.

Ecol. Severe dehydration (>10% fluid loss), may require greater than 100 mL/kg of fluid replacement to restore euvolemia, ideally administered within the first 3 to 4 hours of clinical presentation. Pandemic, toxigenic V. cholerae is discussed in a separate article of this encyclopedia. PLoS Negl. V. cholerae O1 serovar Ogawa was identified as the causative agent in all three cases. V. cholerae, which belongs to either serogroup O1 or serogroup O139, has been associated with epidemic cholera. Rep. 8, 30–37. 9:e0003832. However, globally, cholera cases have increased steadily since 2005 and the disease still occurs in many places including Africa, Southeast Asia, and Haiti. Vet. Available online at: http://www.fehd.gov.hk/news/details/01-09-2003-268.html. Successive appearance of classical and El Tor biotypes, emergence of a novel serogroup O139, and acquisition of some of the classical biotype features by the recent El Tor strains are the important events in the changing epidemiology of cholera.
