Abstract

Introduction: Anopheles mosquito is transmitting malaria, one of the health problems in Indonesia. Understanding Anopheles mosquito behaviour and its breeding preference is one of the crucial keys to prevent malaria transmission. This study aimed to identify the breeding place distribution and bionomics of Anopheles spp. in Runut village, Sikka district, East Nusa Tenggara. Methods: A descriptive observational study was conducted in Runut village, Waigete sub- district, in April 2018. Anopheles spp. larvae were collected in 7 suspected breeding places consisting of 2 rice fields, 3 fish ponds, and 2 puddles. Mosquitos behaviour was observed using bed-net traps located inside and outside the house from 7.15 PM to 1.15 AM after obtaining informed consent. Mosquito collection using bed-net trap were performed for 40 minutes then followed by resting mosquito collection for 10 minutes. Results: Anopheles spp. larvae were found in most of the suspected aquatic habitats, presenting different densities and together with larvae of the other mosquito species. Relatively high number of Anopheles spp. larvae was obtained from a puddle. Only one female mosquito of Anopheles spp. resting on the wall inside house was found around 00.55 – 01.05 AM and resulted in low mosquito density determination. Conclusion: Anopheles spp. larvae were harbouring in most of the aquatic habitats and one puddle contained moderately abundant larvae of Anopheles in Runut village, Sikka district, East Nusa Tenggara, Indonesia. Even only one Anopheles spp. mosquito was detected inside the house, residents in Runut village should regular use insecticide-treated bed nets and continuous observation of mosquito breeding places especially puddles to prevent malaria and other mosquito-borne diseases.

Abstract

Pregnant women are highly vulnerable to malaria infection in its endemic areas, particularly infection by Plasmodium falciparum that can cause premature, low birth weight, severe anemia in pregnant women, and death. Sulfadoxine-pyrimethamine (SP) for Intermittent Preventive Treatment for pregnant (IPTp) is used for malaria control in pregnancy recommended by the World Health Organization that has already been implemented in Africa. The P. falciparum resistance to SP has been reported in several malarial endemic areas, and mutations in the genes of Plasmodium falciparum Dihydrofolate Reductase (Pfdhfr) and Dihydropteroate Synthase (Pfdhps) are shown to be associated with parasite resistance to SP treatment. Genetic analysis of Pfdhfr and Pfdhps genes in pregnant women infected with P. falciparum has not yet been examined in Indonesia. The cross-sectional study was conducted at two subdistricts, Sungai Pinang and Peramasan, in Banjar district of South Kalimantan Province, where 127 pregnant women were recruited from 2008 to April 2010. Two important mutations in Pfdhfr gene (amino acid positions at N51 and S108) and three in Pfdhps gene (A437, K540 and A581) were analyzed by nested PCR-RFLP method. All of the seven pregnant women samples infected with P. falciparum presented PfDHFR 108N and PfDHPS 437G mutations. One of the samples had the additional mutation at PfDHPS 540, in which Lys is substituted by Glu. These results suggested that P. falciparum might present only some resistance to SP at Sungai Pinang and Peramasan subdistricts, Banjar District, South Kalimantan province, Indonesia. Although there were limited number of samples, this study showed only few mutations of Pfdhfr and Pfdhps genes in P. falciparum at Banjar district, South Kalimantan Province, that suggests SP might be effective for IPTp in this area. Thus, further analysis of the other mutation sites in Pfdhfr and Pfdhps genes and in vivo efficacy study of SP with more sufficient sample numbers will be necessary to confirm this preliminarily result.Keywords: PfDHFR and PfDHPS genes, Pregnant women, Falciparum malaria
