epidemiology of brugia malayi infection and its co-existence with wuchereria bancrofti in and around sillaberia phc, district midnapur, west bengal.	of 2186 persons investigated in thirteen villages of sillaberia phc, 19 were found to be infected with brugia malayi and only one person harboured microfilaria (mf) of wuchereria bancrofti. similarly 41 persons exhibited signs and symptoms of chronic filariasis. the mf and disease rates percent worked out to be 0.914 and 1.87 respectively. the earliest ages showing mf and disease manifestations were 3 and 11 respectively. the mean mf density ranged from 2 to 12.2 per 20 cumm of blood. the male a ...	1990	1983013
annual transmission potential of bancroftian filariasis in an urban and a rural area of west bengal, india.	the annual transmission potential of wuchereria bancrofti was calculated from the number of infective larvae found in the number of culex quinquefasciatus expected to bite an individual exposed 24 hr a day for a year in calcutta and in a rural (memari) area. in calcutta, an average of 151 mosquitoes/night/person were collected; it was calculated that 55,028 mosquitoes could bite a person per year, including an average of 177 infective mosquitoes containing 319 infective larvae of w. bancrofti. a ...	1989	2653062
studies on the filariasis vector--culex quinquefasciatus at kanchrapara, west bengal (india).	a nine month entomological and parasitological study was conducted between december 1991 and august 1992, at kanchrapara, a town of the district north 24-parganas, west bengal. the town was found to be endemic for bancroftian filariasis. microfilaria rate among the human population was 1.9 per cent (35 of 1200 persons). average man hour density of c. quinquefasciatus was considerably high (31.10) and a higher vector prevalence was seen in summer. the infection and infectivity rates of the natura ...	1994	8088885
correlation between the preferred biting site of culex quinquefasciatus and the region of the body affected by clinical filariasis.	entomological and filariasis surveys were conducted simultaneously in a rural and an urban environment in west bengal from september 1986 to august 1987. the aim of the surveys was to see if any correlation existed between the preferred biting site of culex quinquefasciatus, the filarial vector, and the region of the body affected by clinical filariasis. significantly more mosquitoes (> 55%) attacked the thighs, legs and feet of human volunteers than other sites on their bodies, whether the volu ...	1993	8250630
prevalence of bancroftian filariasis in burdwan district, west bengal: ii. vector and microfilariae density in colliery and non-colliery areas.	the paper reports the density of culex quinquefasciatus, infection and infectivity rates, microfilariae(mf)- density and microfilaraemic persons in the colliery and non-colliery areas of burdwan district, west bengal. the numbers c. quinquefasciatus were significantly higher in colliery areas, as compared to non-colliery areas. the infection rate and infectivity rates of the vector were found to be higher in colliery areas. the higher vector density in colliery area is one of the major reasons o ...	1995	9163714
lymphatic filariasis in two distinct communities of upper assam.	current status of bancroftian filariasis among two distinct communities of upper assam was evaluated. high prevalence (10.3% mf rate) in tea workers descendents of tribals migrated from endemic states such as orissa, bengal, uttar pradesh and southern states of india, were recorded. among non tea workers (indigenous population) significantly low mf rate was found in spite of the fact that both the communities are living in close vicinity and in similar ecological and mosquitogenic conditions. cu ...	1999	10810596
bancroftian filariasis in bagdogra town, district darjeeling (west bengal).	filaria endemicity is probably gradually increasing over the years in bagdogra town, district darjeeling (west bengal). of 1511 night blood smears examined, 35 were found positive for wuchereria bancrofti (mf rate 2.32%). the microfilaria (mf) rates for males and females were 2.84% and 1.79 % respectively. the age of these positives ranged from 5-45 years. the mf rate was highest (4.46%) in the age group of 20-29 years. all mf carriers were local residents of bagdogra and wuchereria bancrofti wa ...	2002	14768828
treatment of microfilaraemics with dec and its effect on vector infection and infectivity in tribal and non-tribal areas of bankura district, west bengal, india.	single course dec treatment (6 mg/kg body weight/day for 12 days) was administered to 66 tribal and 442 non-tribal microfilaria (mf) carriers detected through a filariasis survey in bankura district, west bengal, india. all the mf carriers remained amicrofilaraemic on 22nd, 180th and 365th post-treatment day. as a result of dec treatment to the mf carriers, vector (culex quinquefasciatus) infection rate in tribal study areas reduced from 2.06% to 1.07%. infectivity rate was "nil" both before and ...	2003	15239303
lymphatic filariasis in the coastal areas of digha, west bengal, india.	the state of west bengal, india, has a long coastline with the bay of bengal. no information exists regarding filarial epidemiology and its vector in these coastal areas. the present study was designed to assess the epidemiology of lymphatic filariasis and the role of available mosquitoes as its vector in eight coastal villages around digha, west bengal. night blood samples of 4016 individuals were collected and each of them was examined clinically for any manifestations of the disease. overall, ...	2007	17716494
effect of single to triple dose dec on microfilaremics up to 5 years.	a 5-year study was conducted with 200 selected microfilaremic subjects bearing mean microfilarial density (mmd) of 11.6 from 16 small foothill villages around susunia hill, bankura, west bengal during june 2001 to may 2002. all of them were treated with a single dose (6 mg/kg body weight) to triple dose diethylcarbamazine (dec). on day 180, 365, 730, 1,095, 1,460, and 1,825, recurrence of microfilaremia were 0.0%, 6.0%, 15.5% (6 + 9.5), 27% (15.5 + 11.5), 42% (27 + 15), and 49% (42 + 7), respect ...	2008	18677655
