| distribution and density of mosquitoes in two endemic areas for bancroftian filariasis in sorsogon, philippines. | mosquito density in rangas where abaca is in abundance is much higher, almost twice, than that of putiao where abaca is absent. the adult density of aedes poecilus over aedes ananae in the two areas combined is 3 to 4 times whereas the larval density of the former is much lower than aedes ananae. the banana axils is a favorite breeding place for aedes poecilus but may also utilize the abaca axils. this finding is very favorable in the transmission of bancroftian filariasis because this species o ... | 1978 | 34889 |
| vector mosquitoes of wuchereria bancrofti at bicol region in the philippines. 1. transmission capability. | mosquitoes were surveyed for the capability of filaria transmission at sitio bacolod and barrio salvacion, in bicol region, luzon, philippines. the results of indoor collections and experimental infections showed that the infective rates and the median density of infective larvae per infected mosquito were significantly higher in aedes poicilius than in culex quinquefasciatus. aedes poicilius was found to be the principal vector of bancroftian filariasis in this region. | 1985 | 3900489 |
| detection of bancroftian filariasis in human blood samples from sorsogon province, the philippines by polymerase chain reaction. | the polymerase chain reaction (pcr) was used for diagnosing wuchereria bancrofti infection in a small village in the province of sorsogon, the philippines. of 54 night-time blood samples collected, 4 (7.4%) were found to be microfilaremic as determined by combined direct blood film examination and membrane filtration of blood followed by blood film examination. however, utilization of the sspi pcr assay to detect repeated w. bancrofti dna sequences in human blood doubled the number of microfilar ... | 2001 | 11511008 |

| sensitivity and specificity of skin reactivity to brugia malayi and dirofilaria immitis antigens in bancroftian and malayan filariasis in the philippines. | saline antigen extracts of microfilariae, adult worms and third-stage larvae of subperiodic brugia malayi maintained in gerbils were prepared for use as skin test reagents. patients were studied on three different islands in the philippines, one endemic for bancroftian filariasis (sorsogon, luzon), another endemic for malayan filariasis (palawan) and the third without endemic filariasis (cebu). a dose-response curve was established initially in patients with bancroftian filariasis: thereafter 1. ... | 1977 | 322516 |
| an epidemiological study of filariasis in sorsogon province, republic of the philippines, with notes on experimental mosquito infection. | an epidemiological survey was conducted on bancroftian filariasis in sorsogon province, the philippines, with special regard to low density microfilaremia (ldf). filtration technique using nuclepore membrane examining 1 ml blood revealed 31% positive rate for microfilaria out of 262 volunteers. out of 82 positives 21 (25.6%) had ldf (less than 10 in 1 ml blood). no conspicuous grouping of ldf was noted in younger age groups or sexes. in three out of 12 clinical filariasis, microfilaria was detec ... | 1983 | 6136616 |
| components of the vectorial capacity of aedes poicilius for wuchereria bancrofti in sorsogon province, philippines. | components of vectorial capacity (biting density, survival, and host preferences) of a population of aedes (finlaya) poicilius, the principal vector of wuchereria bancrofti in the philippines, were studied in 1994-1995 in sorsogon province. aedes poicilius comprised 20.7% of 3243 mosquitoes of 24 species taken in 42 nights of human-biting collections, and 1.4% of 7586 mosquitoes of 27 species taken in 18 concurrent nights of carabao-trap collections. there were, on average, 16 bites by ae. poici ... | 1998 | 9797834 |
