Abstract

In addition to the previously known of subperiodic and periodic form, the nonperiodic form of B. malayi Lichtenstein was recently reported from East Kalimantan as a new filarial different subspecies. The morphology or natural habitat of filarial parasite was recently described. This paper reports daytime transmission of the disease found in highly endemic area of Dayak, indigenous inhabitants of Krayan area, Long Ikis district, Pasir regency, East Kalimantan. To show such transmission, the microfilaria carrier was followed by daily activities at daytime. When the carrier was at work in the forest, the wild mosquitoes landing and feeding on him were collected, then reared in a laboratory until 14 days. The remains alive of mosquitoes were then morphologically identified and dissected. Infective larvae were recovered from 2 dissected mosquito species, Mansonia bonnae and Mansonia uniformis. Out of 131 alive mosquitoes dissected, 15 (consisting of 10 Ma.bonneae or 13,0% and 5 Ma. uniformis or 11,6%) were found infectious, from which 23 recovered and 11 filarial larvae respectively. Totally, 34 infective B.malayi larvae recovered: 24 larvae from the head and another 10 from the thorax.Key words: Brugia malayi - nonperiodic form - daytime transmission - Mansonia bonnae - Mansonia uniformis

Abstract

Backgound: The nocturnally periodic form of B.malay/ was reported as health problem both in Cheju, Korea and Bireuen, Aceh, Indonesia. The filarial worm was transmitted respectively by Ae.togoi in Korea and An.barbirostris in Indonesia.Objectives: To know any difference of microfilarial behaviour in peripheral blood by meta-analisis on available data published by previous workers.Methods: Using Aikat and Das formula of statistical analysis.Results: B.malayi s microfilariae tend to present at peripheral blood at day time among cases in Cheju, Korea more than those in Bireuen, Aceh, IndonesiaConclusion: B.malayis microfilariae in Cheju, Korea still had tendency to show                  (nocturnally) subperiodicmore than those in Bireuen, Aceh. Key words: filariasis      - B.ma/ayis microfilaria variant        - nokturnally periodic      - nocturnally subperiodic

Abstract

Background: New filarial worm subspecies, i.e. nonperiodic form of Brugia malayi Lichtenstein, was recently reported from East Kalimantan in addition to the previously known subperiodic and periodic form of the species, which was endemic in some rural areas in Indonesia.Objectives: (1) To search new endemic areas of filariasis in the indigenous people and newcomers. (2) To know current status of the disease among schoolchildren in the study areas.Subjects: Schoolchildren in the settlement of Dayak indigenous people (Krayan and Kayungo villages) and transmigrants (Petung UPT: Girimukti and Petung villages), belonging to Long Ikis and Penajam subdistricts, the district of Pasir.Methods: Based on the microfilarial character of aperiodic, blood examinations by simple or concentration method on schoolchidren were carried out at day time within school hours in 1987/1988.Results: (1) Endemic areas of the B. malayi subspecies were discovered, not only in the villages where the schools were situated, but their vicinities as well, i.e. the school childrens home villages. The other schoolchildrens home villages found as endemic areas were Jemparing, Nipaulo, Olung, Sepingan around the Dayak settlements and Lawe-lawe, Tanjung Jumlai, Salakloang, Tunan around the UPT of Petung. (2) Higher microfilaremia rates were found in schools in Krayan (26,0% or 52/200 children) and Kayungo (14,8% or 16/108 children). In the transmigrant settlement, although the concentration methods of examinations were adopted, lower microfilaremia rates were recorded such in schools in the villages of Girimukti (6,9% or 34/490 children) and Petung (3,5% or 33/950 children).Conclusions: Day-time blood survey at school was proved to be a simple method to discover endemic areas of the nonperiodic form of B. malayi in East Kalimantan.Key words: B.ma/ayi - nonperiodic form - daytime examinations - school children

Abstract

Background: Nonperiodic form of B. malayi of human parasite was recently identified in East Kalimantan by Sudjadi as different subspecies in addition to the previously known periodic and subperiodic form of infraspecific variation.Objectives: To detect any changes in microfilarial periodicity in the intergradation area of Mahakam delta with the subperiodic type from South Sulawesi, genealogically related to local population. Methods: Periodicity examinations were carried out on the microfilarial carriers discovered in the B. malayi endemic area of Mahakam delta. Blood examinations (60 mm3 blood) was carried out every 2 hours, in 24 hour cycles. Result analysis was performed using Aikat and Das statistical formula. Results: Six microfilaria carriers of B. malayi were examined for periodicity study. Cases of the nonharmonic or noncircadian form were predominantly (in 5 cases) recorded and only in one case the microfilariae were showed a harmonic or circadian wave pattern,, but with a peak hour at day time, ie 15.5400". Conclusion: No change of the microfilarial periodicity was recorded in the intergradation zone of Mahakam delta. The B. malayi filarial worm was still showing a nonperiodic wave pattern as different subspecies apart from the subperiodic and periodic form of filarial worm.Key words: B. malayi - microfilarial periodicity - intergradation area - non periodic form - subperiodic form

Abstract

Morphological observations were made on the adult filarial worms of nonperiodic form of B.malayi (32 worms), the new subspecies of the causative agent of filariasis in East Kalimantan (3,4). The filaria parasites were compared to the old subspecies of nocturnally subperiodic form of B.malayi (25 worms) from Kendari and the animal filaria of B.pahangi (20 worms) which were also sympatric in East Kalimantan. The adult filarial worms (originated from human/animal carrier) were available from dissection of artificially infected laboratory animal of Meriones unguiculatus. For the artificial infection, Aedes togoi Theobald mosquito were used as laboratory vector.The observations revealed a morphological gap, between B.malayi (nonperiodic form) and B.pahangi coexisting in East Kalimantan showed a reproductive isolation as a different species. Morphologically, the B.malayi from East Kalimantan should be put in the same species category with the nocturnally subperiodic form of B.malayi from Kendari. Showing more anthropo or zoophilic (cf 1,2) properties of parasite intraspecific variabilities in morphology, were also recorded from the filarial worms with an average of the nonperiodic form shorter than the nocturnally subperiodic form of B.malayi, but longer than the animal parasites of B.pahangi.Key words: B. malayi — morphological gap — reproductive isolation — morphological variabilities

Abstract

Nonperiodic form of B. malayi was recently discovered as a new infraspecific variant (new subspecies) of filarial parasite found among Dayak Indigenous people living scattered in deep forest of East Kalimantan. In this research, clinical or blood (including membrane filter concentration method) examinations were carried out on Bugis or Banjar tribais in kampongs or more open areas in East Kalimantan. The malayan filariasis infections were detected among them, but not in high prevalence nor microfilarial density, such as found in two villages in Mahakam delta or another one In Bontang area, Kutai regency. The clinical manifestations, however, were not severe nor specific.Key words: Brugia malayi - nonperiodic form - Bugis and Banjar settler - natural selection pressure - parasite dispersal.

Abstract

A new subspecies of sylvanic or human filarial worm, i.e. nonperiodic form of Brugia malayi Lichtenstein, was recently discovered in East Kalimantan, which was highly prevalent among Dayak indigenous people living in the deep forest. This paper reports the filarial infections among transmigrants coming from Java who have been resettled for about 30 years in the UPT (unit of transmigration resettlement) of Petung, Penajam district, Pasir regency. Higher filarial infections were recorded among transmigrants living in hilly parts of the UPT, such as those found in Gunungrejo subvillage, with a micro-filarial rate of 6.3%, clinical rate of 8,1% or filariasis rate of 12,9%, out of 520 people examined. In more swampy areas, such as those found in Kedungrejo subvillage, the parasite Infection rate was much lower, and was recorded only 3,1%, out of 578 people examined. The result of blood or clinical examinations carried out in this research also indicated that male and older Inhabitants or transmigrants who have stayed longer in Kalimantan have a higher risk of Infection.Key words: transmigrants - Brugia malayi - nonperiodic form - sylvanic filaria - mansonia
