Vibrio cholerae O1 biovar El Tor strain M893

Vibrio cholerae O1 biovar El Tor strain M893 is a Gram-negative, rod-shaped bacterium notable for its role in causing cholera, a severe diarrheal disease. This strain is classified as a heterotroph, indicating that it derives its energy from organic compounds. It has a facultative anaerobic oxygen requirement, allowing it to thrive in both aerobic and anaerobic environments. M893 is characterized by its single-cell arrangement and the presence of flagella, which contributes to its motility. However, the strain itself does not exhibit mobility, which may suggest reduced movement capabilities under certain conditions. The optimal growth temperature for this strain is around 20°C, placing it within the mesophilic temperature range, which typically spans from approximately 20°C to 45°C. Vibrio cholerae O1 biovar El Tor strain M893 has one replicon and is surrounded by two membranes, consistent with the structural features of Gram-negative bacteria. Its ecological role is that of a free-living organism, indicating its capability to exist independently in various habitats. The health effects of this strain are significant, as it is responsible for cholera outbreaks, which can lead to severe dehydration and mortality if not treated promptly. Understanding the biological and ecological attributes of Vibrio cholerae O1 biovar El Tor strain M893 is crucial for developing effective interventions and public health strategies to combat cholera transmission.
