an outbreak of food poisoning suspected to be caused by vibrio fluvialis.a small outbreak of gastroenteritis was reported in june 1981 from arangaon village of maharashtra state, india. of the 34 participants who took lunch in a religious ceremony, 14 became suddenly sick 4 to 6 hours after the meal with clinical manifestations of food poisoning. of the 14 stool samples examined, one from each patient, vibrio fluvialis was isolated from nine without the growth of any other enteropathogenic bacteria. although any left-over portions of food were not available for bacte ...19902081883
a study of v. cholerae strains isolated in bombay.of 935 faecal samples studied over a period of one year, v. cholerae 01 was isolated from 102 samples (10.9%). all the strains were found to be e1 tor ogawa. the strains belonging to the phage types 2 and 4 were encountered in our study, type 2 being the highest (76.5%). the sensitivity pattern of all strains to the commonly used antibiotics was determined. strains sensitive to gentamicin (92.2%), nalidixic acid (85.3%), kanamycin (83.3%), cotrimoxazole (80.4%) and chloramphenicol (75.5%) were o ...19902102910

outbreak due to vibrio cholerae e1 tor & serotype o139 in yavatmal (maharashtra) during june-july, 1994.a total of 65 strains of v. cholerae were isolated during june-july 1994 at yavatmal (maharashtra). of the 65 strains isolated, 62 were 01 el tor vibrios, while three were non 01 serotype 0139. the novel epidemic strain designated as 0139 reported during the outbreak in 1993, has been supplanted by the usual el tor vibrio during the present outbreak while 0139 serotype has remained sporadic.19957729850
changing bacteriological profile of cholera in nagpur, 1991-93.in nagpur (maharashtra) during the period 1991-93, vibrio cholerae serogroup 01 predominated in 1991 (94.7%) and 1992 (86.4%) but significantly declined in 1993 (10.7%). serogroups 02-0138 were infrequently encountered. a new strain v. cholerae serogroup 0139 emerged in 1993 and accounted for 89.3 per cent of the total vibrios isolated in the year. replacement of the endemic 01 strain by the new 0139 strain was observed.19947959972
endemicity of cholera among rural areas of loni, ahmednagar district of maharashtra.a total of 130 vibrio cholerae strains isolated during november 1989 to december 1992 from the rural population of loni areas--ahmednagar district of maharashtra were characterised. of these isolates, 124 were el tor vibrios serotype ogawa, and 6 were el tor vibrios serotype inaba. one hundred twenty two strains belonging to t4 phage, while 8 strains of el tor vibrio serotype ogawa were untypable. all the strains isolated, showing haemolytic and non-haemolytic colony variants of el tor v. choler ...19947959973
cholera outbreak due to vibrio cholerae serogroup 0139 in yavatmal (maharashtra) in march-july, 1993.a total of 34 strains of v. cholerae were isolated during march to july, 1993. of the 34 v. cholerae isolated 26 strains were non 01 and remaining eight were 01 el tor vibrio. non-01 strains were identified as novel epidemic strains designated as 0139. the shift in the relative and absolute prevalence of v. cholera serotype 01 and non 01 was noted.19948063341
characteristics of vibrio cholera 0139 strains isolated in sevagram (maharashtra) during april-august 1993.a total of 44 strains of vibrio 0139 serotype isolated between april and august 1993 at sevagram (wardha) were examined for expression of a number of biochemical and physiological characteristics. all strains fermented lactose within 24 h and belonged to heiberg group iii. salt tolerance to 8 per cent nacl was seen in 22.72 per cent strains. haemolysis of sheep rbcs and haemagglutination of human 'o', chicken and rabbit rbcs was consistently positive. all the strains were sensitive to tetracycli ...19948063342
emerging & re-emerging bacterial pathogens in india.in spite of major successes against infectious diseases in the 20th century, new infectious diseases have emerged and old ones re-emerged in recent decades in different parts of the world. a brief survey of emerging and re-emerging bacterial diseases of public health importance in india is presented in this paper. plague re-appeared in two outbreaks in maharashtra and gujarat in 1994, indicating a breakdown of the public health measures that had prevented its occurrence for several decades. lept ...19968926026
changing pattern of vibrio cholerae serotype el tor and 0139 in yavatmal (maharashtra, india) during 1992 to 1994.during 1992, 1993 and 1994 a total of 65, 123 and 142 faecal samples respectively yielded 9, 54 and 87 strains of v. cholerae. simultaneous occurrence of el tor vibrio and non 01 (i.e. 0139) was noted during 1993 and 1994 with variations in relative and absolute prevalence of each serotype. seasonal incidence is fairly consistent in this region. both v. cholerae serotypes 01 and 0139 showed resistance to one or more drugs.19979354010
re-emergence of vibrio cholerae serogroup o139 during june-august, 1997 in yavatmal (maharashtra).a clone of v. cholerae serogroup o139 which emerged as a novel epidemic strain, was reported from this region in 1993 as from many other parts of india and adjoining countries. the decline in the isolation rate of this organism in subsequent years was followed by a sudden increase in 1997, this requires careful monitoring.19989745210
re-emergence of vibrio cholerae o139 serogroup during 1998 in nagpur (maharashtra), india.in nagpur, maharashtra in 1993, v. cholerae serogroup o139 emerged as a novel epidemic strain. the decline in the isolation rate of this serogroup in subsequent year was followed by its re-emergence during 1998 indicating that this serotype requires careful monitoring.199910489733

quantitative analyses of pollution-indicator and pathogenic bacteria in mumbai waters from ballast water exchange perspective.as large numbers of ships either take in ballast from or discharge their ballast into the mumbai harbor region, it is pertinent to quantify microorganisms of health concerns and suggest on the suitability of water for ballasting purposes. to meet with this main aim, a selected set of general and pathogenic bacterial groups and their seasonal variations were studied from the mumbai harbor area. sampling was carried out during postmonsoon (november 2001), pre-monsoon (april 2002) and monsoon (octo ...200515931993

on the discovery of the nature of cholera toxin in india.this brief account looks at the discovery of the nature of cholera toxin in india. during the late nineteenth and early twentieth centuries research on cholera was being carried out in bombay and calcutta. robert koch visited india in 1883 and isolated and purified vibrio cholera the following year.this paper considers the contribution of dr sambhu nath de, known best as s. n. de, (1915-1985) to cholera toxin discovery and notes the 2009 conference which honoured his memory.201020977152
icevchind5 is prevalent in epidemic vibrio cholerae o1 el tor strains isolated in india.integrative conjugative elements (ices) of the sxt/r391 family are self-transmissible mobile elements mainly involved in antibiotic resistance spread among ?-proteobacteria, including vibrio cholerae. we demonstrated that the recently described icevchind5 is prevailing in v. cholerae o1 clinical strains isolated in wardha province (maharashtra, india) from 1994 to 2005. genetic characterization by ribotyping and multiple-locus ssr analysis proved the same clonal origin for v. cholerae o1 isolate ...201121276749
