The sensitivity test of vibrio cholerae from isolation of diarrhea case to various type of antibiotics

One of the microbes that causes acute diarrhea is bacteria. Vibrio cholerae is one that causes diarrhea called cholera diarrhea. Cholera diarrhea is caused by enterotoxins produced by these bacterial colonies in the small intestine. Giving antibiotics is still the main choice in the treatment and treatment of diarrhea because it is expected to kill bacteria and will usually stop diarrhea. Irrational use and the existence of abuse and excessive use of antibiotics can be a factor that causes bacterial resistance to antibiotics. Tests carried out to determine the sensitivity of bacteria to an antibiotic. Vibrio cholerae isolate was regrowed in alkaline peptone (APW) water medium and incubated at 37ºC for 18-24 hours, then planted in the thiosulfate-citrate-bile-sucrose (TCBS) medium. The sensitivity test was carried out on V. cholerae bacterial colonies growing on TCBS agar medium with the Disk Diffusion Method from Kirby Bauer. Data were analyzed descriptively. The results showed that most V. cholerae isolates were still sensitive to all types of antibiotics used in the test. Vibrio cholerae has shown resistance to Colistin antibiotics that is equal to 88.2%, Ampicillin at 23.5% and Ceftazidime at 5.9%. The level of resistance to antibiotics that are still low indicates that the antibacterial group can still be used as an alternative in the treatment of cholera diarrhea.

The history, genome and biology of NCTC 30: a non-pandemic Vibrio cholerae isolate from World War One

The sixth global cholera pandemic lasted from 1899 to 1923. However, despite widespread fear of the disease and of its negative effects on troop morale, very few soldiers in the British Expeditionary Forces contracted cholera between 1914 and 1918. Here, we have revived and sequenced the genome of NCTC 30, a 102-year-old Vibrio cholerae isolate, which we believe is the oldest publicly available live V. cholerae strain in existence. NCTC 30 was isolated in 1916 from a British soldier convalescent in Egypt. We found that this strain does not encode cholera toxin, thought to be necessary to cause cholera, and is not part of V. cholerae lineages responsible for the pandemic disease. We also show that NCTC 30, which predates the introduction of penicillin-based antibiotics, harbours a functional β-lactamase antibiotic resistance gene. Our data corroborate and provide molecular explanations for previous phenotypic studies of NCTC 30 and provide a new high-quality genome sequence for historical, non-pandemic V. cholerae .
