Background Cholera remains a public health issue, especially in developing countries. We report a cholera outbreak in North Delhi. Objective To report the causative agent of outbreak and to characterize, biotype, and analyze antimicrobial resistance pattern of V. cholerae isolated from cholera patients admitted to our hospital. The outbreak occurred from July 2016 to August 2016. Materials and Methods A total of 179 stool samples from pediatrics department were received and processed according to the current Clinical and Laboratory Standards Institute (CLSI) guidelines. Results Out of 179 stool samples received by the laboratory, 26 samples grew Vibrio cholerae O1 Biotype El Tor. Cefotaxime and ceftriaxone were the most sensitive drugs. All isolates were resistant to cotrimoxazole followed by tetracycline. Conclusion According to the World Health Organization (WHO), cholera is becoming endemic in Delhi. Emergence of multiple antibiotic-resistant cholera isolates is a concern. Prompt identification and notification of cholera are the key measures to avert cholera outbreak. Clean water supply and improved sanitation measures should be taken for prevention of cholera.

Six hundred and twenty-four Vibrio cholerae O1 strains, 623 serotype Ogawa and one serotype Inaba, isolated in Romania between 1977–95 were tested to detect all changing traits concerning serogroup, serotype, biotype, phage type and resistotype patterns and subsequently, the possible epidemiological relationship among these strains. Biotyping revealed one classical, 580 eltor strains and 43 intermediary variants. When tested with Mukerjee phages, 546 (87%) strains were sensitive and 78 (13%) resistant. One phage type (M4) dominated during 1977–90, two phage types (M4 and M5) exhibited the same high frequencies during 1991, a diversity of types occurred during 1993–4 whereas in 1995, two phage types (M4 and M5) showed similar distributions again. Five patterns of drug susceptibility were successively described during 1977–95. The most prominent changes in Vibrio cholerae O1 strains were noticed during 1993–4: the highest number of non-typable strains and intermediary variants, the widest spectrum of phage types and of multidrug resistance. In 1995, the strains reverted to the previous typable forms but a new drug resistance pattern was noticed.

Using molecular techniques, we investigated whether the clone of Vibrio cholerae O1 biotype El Tor which appeared in Calcutta, India, in 1994 has spread to other cholera endemic areas in the country. The ribotype of 31 of the 33 strains isolated from different parts of India during 1996 and 1997 was identical to the ribotype displayed by the new clone of V. cholerae O1 which emerged in Calcutta in 1994. Likewise, 12 of the 15 strains examined by pulsed-field gel electrophoresis (PFGE) showed identical profile to that exhibited by the new clone of O1. The restriction fragment length polymorphism (RFLP) of CTX genetic element of these strains also matched with the new clone of O1 which emerged after the outbreak of V. cholerae O139 in Calcutta. However, two strains (AH042 and AH046) isolated from an outbreak in Ahmedabad (western India) showed different CTX RFLP but had the same ribotype and PFGE profile as the new clone, whereas one strain from Goa (G2) showed distinct ribotype and PFGE profile and the CTX RFLP was identical to the O1 strains which prevailed before the genesis of O139 in Calcutta. The drug resistance pattern of most of the O1 strains examined in this study, except strain G2, was similar to that of the new clone of V. cholerae O1. None of the strains in this study carried plasmids. Molecular studies clearly show that the new expanded drug resistant clone of V. cholerae O1 has spread to all cholera endemic areas in India and also provide evidence for the evolution of new clones of the O1 serogroup.

Background: Epidemics of cholera have been reported from various parts of India. We investigated the epidemic of cholera that occurred in and around Yavatmal district in Maharashtra, India 2018, reported during March to July.Methods: 711 stool samples collected from diarrhea patients were bacteriologically analyzed for their identification and antibiogram of Vibrio cholera.Results: The cholera outbreak was caused by V. cholerae O1 Ogawa biotype El Tor. All the V. cholerae isolates from the stool samples were sensitive to tetracycline, doxycycline, ofloxacin, ciprofloxacin gentamycin, cotrimoxazole and resistant to ampicillin and ceftazidime.Conclusions: The present outbreak was due to V. cholerae O1 Ogawa El Tor which seems to have completely replaced O139 serogroup of the previous outbreaks during the last decade.

Since 2007, Kenya has experienced an increase in cholera outbreaks characterized by a high fatality rate. In this study, we characterized 81 Vibrio cholerae isolates from diarrhoeal stool samples in Nyanza, a cholera-endemic lake region of Kenya, for virulence properties, clonality and antibiotic susceptibility. Eighty of these isolates were V. cholerae O1 El Tor variants carrying the classical ctxB gene sequence, while one isolate was V. cholerae non-O1/O139. All of the El Tor variants were of clonal origin, as revealed by PFGE, and were susceptible to ampicillin, tetracycline, ciprofloxacin, fosfomycin, kanamycin and norfloxacin. However, the isolates showed resistance to sulfamethoxazole/trimethoprim and streptomycin, and intermediate resistance to nalidixic acid, chloramphenicol and imipenem. The non-O1/O139 isolate carried the cholix toxin II gene (chxA II) and was susceptible to all antimicrobials tested except ampicillin. We propose that an El Tor variant clone caused the Nyanza cholera outbreak of 2007–2008.
