| mosquito blood feeding patterns as a factor in the epidemiology of japanese encephalitis in southern india. | determinations were made of the source of 16,330 bloodmeals from 10 species of culex mosquitoes, including recognized vectors of japanese encephalitis (je) virus, in two epidemiologically distinct areas in southern india. in madurai, where cases occurred sporadically and pigs were reared only in some villages, cx. tritaeniorhynchus, cx. pseudovishnui, and cx. vishnui had fed predominantly on cattle (89.2-91%), but less frequently on humans (2.1-6.2%) and on pigs and ardeid birds (0-0.1%). in nal ... | 1992 | 1320343 |

| incidence & enteropathogenicity of aeromonas spp in children suffering from acute diarrhoea in chennai. | a total of 200 stool samples from children below 10 yr suffering from diarrhoea were screened for enteric pathogens with special interest on aeromonas. aeromonas spp were isolated from 6.5 per cent of the patients, comprising 4 per cent a. hydrophila, 2 per cent a. sobria and 0.5 per cent a. caviae. among the 13 isolates obtained, 10 isolates produced enterotoxin in ligated rabbit ileal loops, and 11 produced cytotoxin in hep 2 cells. many of the aeromonas isolates exhibited resistance to common ... | 1998 | 9701892 |
| prevalence, in-vitro secretory activity, and cytotoxicity of aeromonas species associated with childhood gastroenteritis in chennai (madras), india. | an investigation on the prevalence of aeromonas in gastrointestinal illnesses of pediatric inpatients 1 month to 3 years of age was conducted from february 1997 through january 1998 in madras. sixteen aeromonas spp. were isolated from 11 male and five female children among the 341 pediatric inpatients suffering from acute diarrhoea. a. caviae, which was isolated from nine cases, was found to be the most predominant isolate, followed by a. veronii biovar sobria, isolated from six cases, and a. hy ... | 1998 | 10211427 |
| biochemical characteristics & secretory activity of aeromonas species isolated from children with gastroenteritis in chennai. | an attempt was made to delineate the phenotypic markers for the detection of enterotoxigenic strains of aeromonas. eighteen aeromonas species comprising one isolate of a. hydrophila, six isolates of a. sobria and 11 isolates of a. caviae were obtained from 379 children suffering from acute diarrhoea in chennai. nine of these isolates inclusive of three a. sobria and six a. caviae were found to produce secretory response in vitro in the rabbit intestinal mucosa mounted in the ussing chambers as r ... | 1999 | 10402760 |
| enterotoxigenicity of klebsiella pneumoniae associated with childhood gastroenteritis in madras, india. | klebsiella pneumoniae was isolated as the predominant growth from 12 of 100 children under 3 years of age suffering from acute diarrhea. of the 12 isolates, sa1, sa2, sa4, sa5, sa6 produced a secretogenic response in the ligated rabbit ileal loop, and one isolate, sa3, induced a diarrheagenic response in suckling mice. two isolates, sa7 and sa8, were diarrheagenic in both assays. strains sa9, sa10, sa11, and sa12 were found to be non-enterotoxigenic. these isolates belonged to serotypes k6, 16, ... | 1999 | 10808254 |
| bacteriological profile of cholera in tamil nadu (1980-2001). | in addition to vibrio cholerae o1, a recently emerged non-o1 serotype, v. cholerae o139 has also been found to be responsible for epidemics of cholera. in the context of the changing etiology of cholera, the occurrence of different serotypes, biotypes and phage types of v. cholerae in tamil nadu is presented. | 2002 | 12807153 |
| enterotoxigenicity screening of viable environmental vibrio cholerae strains from rainwater pools in a university campus in chennai, south india. | vibrio spp., being primarily inhabitants of the aquatic environment, pose a severe health threat to humans. this problem is escalated in developing countries where water-logging after rainfall is very common. therefore, screening of environmental water samples for the presence of clinically important species of vibrio becomes essential. | 2011 | 21231812 |
