| microfilarial periodicity of wuchereria bancrofti in assam, northeast india. | wuchereria bancrofti has shown nocturnal periodicity in india and other endemic countries of the world except pacific regions where non-periodic or diurnal sub-periodic forms have been reported. presence of sub-periodic form of w. bancrofti in andaman and nicobar islands, india and a case report of sub- periodic form of w. bancrofti from mysore, india provide basis for exploring the periodicity pattern of microfilaria of w. bancrofti prevalent in assam, northeastern region of india. state of ass ... | 2015 | 26418650 |
| impact of mda and the prospects of elimination of the lone focus of diurnally sub periodic lymphatic filariasis in nicobar islands, india. | mass drug administration is being carried out in andaman and nicobar islands, india since 2004. cross sectional microfilaria (mf) survey was conducted in nancowry group of islands, the lone foci of diurnally sub periodic form of bancroftian filariasis in nicobar district, to examine its eligibility for transmission assessment survey (tas). a total of 2561 individuals (coverage: 23.9%) were screened from five islands. the overall mf prevalence was 3.28%. except one island, all other islands recor ... | 2014 | 24556139 |
| lymphatic filariasis elimination programme in andaman and nicobar islands, india: drug coverage and compliance post eight rounds of mda. | lymphatic filariasis (lf) is endemic in the andaman and nicobar islands, including the lone foci for a diurnally sub-periodic form of wuchereria bancrofti in the nancowry group of islands. a programme to eliminate lf was launched in 2004 by the directorate of health services, andaman and nicobar administration which involved a single annual mass drug administration (mda) using diethylcarbamazine (dec) with albendazole. so far, eight rounds of mda have been implemented through the public health c ... | 2013 | 23550201 |
| transmission dynamics of diurnally subperiodic lymphatic filariasis transmitted by ochlerotatus (finlaya) niveus in the andaman & nicobar islands. | in india diurnally subperiodic filariasis is prevalent only in the nicobar district of andaman and nicobar islands, with significant health problem. sample surveys indicated that this form of filariasis is restricted to a small region of nancowry group of islands with ochlerotatus niveus as the vector. we therefore carried out a comprehensive study to assess the transmission dynamics of lf in teressa island in nicobar district in view of its control and evaluation of interventions. | 2008 | 18316851 |
| diurnal pattern of human-biting activity and transmission of subperiodic wuchereria bancrofti (filariidea: dipetalonematidae) by ochlerotatus niveus (diptera: culicidae) on the andaman and nicobar islands of india. | we monitored diel-landing periodicity (biting activity/cycle) of ochlerotatus niveus and the infection/infectivity pattern through human-landing collections on teressa island, which is remotely located in the nicobar district of the andaman and nicobar group of islands of india, for a period of one year. the biting activity was seen throughout the day, exhibiting a bimodal peak, the first at dawn (4:00-6:00 am) and the other towards dusk (5:00-6:00 pm). this pattern was similar during all the se ... | 2005 | 15772320 |
| diurnally subperiodic filariasis in india-prospects of elimination: precept to action? | the elimination of lymphatic filariasis in the andaman and nicobar islands provides unique opportunities and challenges at the same time. since these islands are remote, are sparsely populated, and have poor transport networks, mass drug administration programs are likely to be difficult to implement. diurnally subperiodic wuchereria bancrofti vectored by downsiomyia nivea was considered for the scope of vector control options. considering the bioecology of this mosquito, vector control includin ... | 2011 | 21286754 |
| survival of diurnally sub periodic wuchereria bancrofti in downsiomyia nivea (diptera: culicidae): a density dependent factor from andaman & nicobar islands. | in india, diurnally sub periodic wuchereria bancrofti transmitted by downsiomyia nivea is prevalent only in the nicobar district of andaman and nicobar islands. the ongoing lf elimination programme aims at transmission interruption by bringing down the microfilarie (mf) load in the community, which has implication on the parasite load in mosquito vector. therefore, understanding density dependent constraints on transmission assumes significance from control perspective. the present study was und ... | 0 | 24604052 |
| genetic variability of diurnally sub-periodic wuchereria bancrofti in nicobarese tribe of nicobar group of islands, andaman and nicobar islands, india. | sub-periodic form of wuchereria bancrofti occurs in several well-isolated islands of nicobar group of islands of andaman nicobar archipelago, india, presenting an interesting situation to study the genetic variability of its population. microfilariae collected from 40 microfilaria (mf) carriers residing in eight locations on five islands (five carriers from each locality) were studied for genetic variability by generating random-amplified polymorphic dna profiles. phylognetic analysis of the pro ... | 2008 | 18320222 |
| prevalence of diurnally subperiodic bancroftian filariasis among the nicobarese in andaman and nicobar islands, india: effect of age and gender. | we conducted a cross-sectional survey to assess the prevalence of disease and microfilaraemia caused by diurnally subperiodic strain of wuchereria bancrofti transmitted by day biting aedes niveus in teressa island, remotely located in the nicobar district of andaman and nicobar islands. lymphatic filariasis is a considerable public health problem on this island with an overall endemicity rate of 16.2%. there was a gradual increase in microfilaraemia prevalence with age, reaching a plateau above ... | 2002 | 12390601 |
| epidemiology of subperiodic wuchereria bancrofti infection in the nicobar islands, india. | diurnally subperiodic filariasis due to wuchereria bancrofti has been reported from tribal populations in the nancowry group of islands in the andaman and nicobar islands, india. this was confirmed in a survey carried out during the monsoon season in 1993. microfilariae were detected in the peripheral blood throughout a 24 h period with a peak at 18:00. the microfilaria (mf) rate ranged from 1.2% to 18.7%, with a low disease rate (mean = 1.9%). incidence of mf was low in children less than 10 ye ... | 1995 | 7778141 |
