Of the 523 rotavirus-positive stool specimens, 245 were examined for subgroup, serotype, and electropherotype. Of these, 84 isolates were analyzed for their subgroup and RNA electropherotype specificites, 12 (14.3%) were of subgroup 1, 69 (82.1%) were of subgroup II, and 3 (3.6%) were a mixture of subgroup I and II. Of the subgroup 1 specimens, 5 (41.7%) showed long electrophoretic migration patterns and 7 (58.3%) showed short patterns. In subgroup II specimens, 66 (95.7%) were of long patterns and 3 (4.3%) of short patterns. The relationship between HRVS serotypes and electropherotypes was also determined for the same 245 rotavirus specimens. Of these, 36 (14.7%) exhibited short RNA patterns and 209 (85.3%) exhibited long patterns. The short pattern specimens consisted of serotype 1 (8.3%), serotype 2 (63.9%), serotype 3 and serotype 4 (2.8%) each. The long pattern specimens consisted of serotype 1 (60.3%), serotype 2 (1.4%), serotype 3 (7.2%) and serotype 4 (17.7%). Among the previous 245 specimens, subgroup specificities were available for 51 specimens. All subgroup I were of serotype 2, and all subgroup II were of serotype 1, 3 or 4. RNAs of either subgroup showed both long and short electropherotypes. No relationship could be established between subgroups or serotypes and a particular electropherotype. It seems unlikely that electropherotyping of human rotavirus (HRV) can be used for identifying the subgroups or serotypes of strains.","PeriodicalId":77203,"journal":{"name":"Journal of diarrhoeal diseases research","volume":"14 3","pages":"201-6"},"PeriodicalIF":0.0,"publicationDate":"1996-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19979872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epidemiological data of 396 cholera cases were collected before the patients' discharge from IDH. Of the 1528 laboratory-confirmed cholera cases, 46% and 54% were caused by serotype O1 and O139 respectively. Both serotypes appeared and disappeared simultaneously, and peaked during the same time of the year. However, the two serotypes affected persons of different age groups; about 65% of the O1 cases occurred in children aged less than 10 years, whereas this age group accounted for 40% of the cases due to V. cholerae O139. Although there were some focal outbreaks due to serotype O139, both serotypes had almost similar geographical distributions. Important risk factors for transmission of cholera were almost equally prevalent in the majority of both types of cholera cases. Since the seasonality, geographical distribution, and risk factors for transmission were similar for both serotypes, the study indicates that the preventive and control measures are also likely to be similar. The study also shows that the emergence of V. cholerae O139 in 1993 did not affect the incidence, seasonality, and epidemiology of endemic V. cholerae O1 E1 Tor strains in Delhi.","PeriodicalId":77203,"journal":{"name":"Journal of diarrhoeal diseases research","volume":"14 3","pages":"182-6"},"PeriodicalIF":0.0,"publicationDate":"1996-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19977291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, an increase in the number of Shigella sonnei isolates was noticed. A retrospective analysis of 2,710 isolates, obtained from stools of Turkish children between January 1980 and September 1994, revealed that, between 1980 and 1987, S. flexneri was the most common subgroup. The isolation rate of S. sonneri increased steadily from 1987 to 1994 reaching to a peak of 78% of all isolates in 1991. The antibiotic susceptibility of 206 strains isolated in 1994 was also studied. A marked difference between the two species was observed for chloramphenicol (98% susceptibility in S. sonnei versus 20% in S. flexneri, ampicillin (90% vs. 18%), ampicillin-sulbactam (98% vs. 53%), and tetracycline (46% vs. 18%) (p < 0.001). Susceptibility to trimethoprim-sulphamethoxazole was similar between the two groups (42% vs. 38%). All isolates were susceptible to ciprofloxacin and ceftriaxone. Comparing our results with resistance rates in 1989, a marked increase in amplicillin (from 44.1% to 82%), chloramphenicol (from 36.7% to 56%) and trimethoprim-sulphamethoxazole (from 35.8% to 62%) resistance was observed.","PeriodicalId":77203,"journal":{"name":"Journal of diarrhoeal diseases research","volume":"14 3","pages":"187-9"},"PeriodicalIF":0.0,"publicationDate":"1996-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19977292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
