Abstract
Vibrio cholerae is an enteric pathogen causing an
acute diarrheal disease known as cholera. The
disease is acquired through the consumption of food
or water contaminated by this microorganism.
Antibiotic therapy is recommended in specific
situations to significantly reduce the volume of
watery faeces and duration of diarrhoea, reducing
the transmission of infection. The wide use and
abuse of antibiotics in human and veterinary
medicine, agriculture, and aquaculture systems have
caused the emergence of antimicrobial resistance
(AMR) in V. cholerae. Several epidemics worldwide
were caused by multidrug-resistant (MDR) V.
cholerae. Various resistance patterns are reported
among clinical strains isolated from different parts
of the country and across the globe. The drugresistant
clinical strains are dispersed into the
aquatic environment through faeces/ excreta of
humans, discharge from health care facilities or
contaminated groundwater. In the aquatic environment,
V. cholerae that are susceptible to antibiotics
acquire resistance either by frequent exposure to
antibiotics over a period of time or through the
transfer of resistant genes from other resistant
bacteria. In the aquatic system, genetic exchange
between bacteria is readily facilitated resulting in
the higher frequency of AMR V. cholerae and more
commonly exhibited multiple antibiotic resistance.
