Abstract
Background and Aim:Lymphatic filariasis (LF) is a lesser-known parasitic disease, which contributes to significant decreases in overall health. This study investigated the presence of Brugia malayi in mosquitoes collected in the South Borneo Province, Indonesia.Materials and Methods:Mosquitoes were collected through bare leg collection methods after sunset in several areas of the Hukai and Gulinggang villages in the Balangan District. The collected mosquitoes were identified based on morphological features and dissected to find microfilaria and then pooled through species for polymerase chain reaction (PCR) microfilaria detection.Results:A total of 837 female mosquitoes consisting of at least 14 species were selected; they were dissected, and no microfilariae were found. Mosquitoes were divided into 69 pools for PCR analysis. PCR revealed that 8.7% (6/69) of the pools were positive for B. malayi, including Mansonia annulifera (4 pools), Aedes albopictus (1 pool), and Culex tritaeniorhynchus (1 pool).Conclusions:These results suggested that mosquito dissection was not an optimum method for finding microfilaria. M. annulifera, C. tritaeniorhynchus, and A. albopictus mosquitoes might play an important role in the transmission of LF in the Balangan District. Information from this study could be used for the prevention of transmission or vector control programs in Indonesia.
Highlights
Lymphatic filariasis (LF) remains a public health problem and possesses a significant morbidity risk to a large proportion of low-income individuals and families in several countries [1,2]

Summary
Lymphatic filariasis (LF) remains a public health problem and possesses a significant morbidity risk to a large proportion of low-income individuals and families in several countries [1,2]. 50% of infections are those who live in Southeast Asia, including Indonesia [3]. Once this parasite enters the host, the worms lodge in the lymphatic vessels of the host and causes swelling of the arms, legs, and genital organs, leading to debilitating impacts and suffering to the patient [4]. The Indonesian Ministry of Health has applied two strategies. Lymphatic filariasis (LF) is a lesser-known parasitic disease, which contributes to significant decreases in overall health. This study investigated the presence of Brugia malayi in mosquitoes collected in the South Borneo Province, Indonesia
