| a community-based study of subclinical flavivirus infections in children in an area of tamil nadu, india, where japanese encephalitis is endemic. | a characteristic feature of the epidemiology of japanese encephalitis (je) is the occurrence of a large number of subclinical infections. the reporting of only overt cases underestimates the total level of virus transmission, a knowledge of which is essential for the evolution of control strategies. we carried out a 3-year prospective serological study between 1989 and 1991 in a primary health centre in tamil nadu where je is endemic. each year paired specimens, taken before and after the transm ... | 1995 | 7743596 |

| 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 |

| virulence for guinea pigs of tubercle bacilli isolated from the sputum of participants in the bcg trial, chingleput district, south india. | this study, conducted in madras, india and in madison, wisconsin, usa, was concerned with the virulence of isolates of mycobacterium tuberculosis obtained from the sputum of individuals living in the chingleput district of south india. the following results were obtained. 1. the findings of mitchison with respect to the predominance of low virulence for guinea pigs among isolates from persons living madras, were confirmed on isolates from the sputum of residents of the chingleput district. 2. a ... | 1987 | 3116731 |
| lipids of putative relevance to virulence in mycobacterium tuberculosis: phthiocerol dimycocerosate and the attenuation indicator lipid. | lipid compositions of 40 patient isolates of mycobacterium tuberculosis derived from madras, burma, rangoon, and east africa were studied, and two major populations of tubercle bacilli were distinguished. nearly all of the strains previously designated as attenuated for the guinea pig (d. a. mitchison) are characterized by a specific phenolic phthiocerol diester which is identified with the aglycone moieties of mycosides a and b (and probably g). this lipid (ai) was not seen in any of the more v ... | 1974 | 4271720 |
| japanese encephalitis in south arcot district, tamil nadu, india: a three-year longitudinal study of vector abundance and infection frequency. | in the south arcot district, an area endemic for japanese encephalitis in tamil nadu, culex tritaeniorhynchus giles, culex vishnui theobald, culex gelidus theobald and culex fuscocephala theobald constituted 93.6% of 422,621 adult females representing 27 culicine species collected between august 1991 and july 1994. vector abundance was lowest in the hot and dry season (april-june) and highest in the cool and wet season (october-december). overall, 285,531 adult female mosquitoes (5,710 pools) we ... | 1997 | 9439119 |
| low rate of japanese encephalitis infection in rural children in thanjavur district (tamil nadu), an area with extensive paddy cultivation. | in thanjavur district, the occurrence of japanese encephalitis (je) is very low and the district is free of epidemics. among children aged 5-12 yr, the infection rates for je in two consecutive transmission seasons of 1991-92 and 1992-93, were 1.8 and 5.1 per cent respectively. a high cattle to pigs ratio (400:1) could possibly be an important factor for the low je infection rate in children in the district. | 2000 | 10969489 |

| fasciolopslasis--a re-emerging infection in azamgarh (uttar pradesh). | fasciolopsiasis is endemic in the far east. in india, there have been a few reports of the infection, prior to the 1990's. we report two cases from azamgarh district of uttar pradesh. both the cases were from nearby villages where water chestnuts are cultivated. these may be a source of infection. pigs are commonly observed in these areas and and may be the source of ova. the only missing link is the finding of infected snails. presence of at least three cases (one reported earlier) in the area ... | 2000 | 12583425 |
