Abstract

Anthelmintic resistance to gastrointestinal nematode of sheep and goats has been reported world wide to all of broad spectrum anthelmintic types currently available, such as benzimidazoles, levamizole and ivermectin. In South-East Asia anthelmintic resistance to small ruminants was reported in Malaysia, Thailand and Philippines. In Indonesia resistances to albendazole have been reported from sheep farm in Bogor. With regard to resistance cases, early detection for anthelmintic resistance on sheeps and goats to spesific types of anthelmintic that commonlly used are required to plan rationale strategic control program. Detection methods for anthelmintic resistance are Fecal Egg Count Reduction Test (FECRT), Egg Hatch Assay (EHA) and Larval Development Assay (LDA). LDA is an in vitro assay to detect anthelmintic resistant in the major of gastrointestinal nematodes on sheep and goats that have just been introduced in Indonesia. This paper explains the comparison of three detection methods and goodness of LDA compared with other two methods.   Key words: Anthelmintic resistance, sheep, goat, Fecal Egg Count Reduction Test (FECRT), Egg Hatch Assay (EHA), LarvalDevelopment Assay (LDA)

Abstract

The intensive usage of anthelmintic in most of farms led to resistances of livestock gastrointestinal nematodes against anthelmintic.  Many  reports  of  resistance  that  increased  every  year  happen  following  the  continuing  helminth  control programmes. The succesful implementation of helminth control programmes that designed to minimize the development of resistance in nematode populations depends on the availability of effective and sensitive method for its detection and monitoring. A variety of in vivo and in vitro tests have been developed for detecting nematode population resistance to the main  anthelmintic groups. This paper will discuss the development of detection method of anthelmintic resistance based on conventional and molecular approach according to their strengths and weakness.   Key words: Anthelmintic resistance, detection method, conventional, molecular, nematode

Abstract

Evidence of anthelmintic resistance of Haemonchus contortus to benzimidazole groups based on Larval development assay (LDA) and Fecal egg count reduction test (FECRT) test has been reported in some areas in Indonesia. Studies on sheep parasite H. contortus have shown that resistance to benzimidazole drugs is correlated with selection for individuals in the population possesing a spesific isotype-1 β tubulin gene. The aim of this study was to determine mutation on central part of isotype-1 β tubulin gene of benzimidazole resistant strain H. contortus using Single Strand Conformation Polymorphism (SSCP). H. contortus worms were isolated from four sheep from two government farms that resistance to benzimidazole have been occurred (SPTD Trijaya, Kuningan, West Java and UPTD Pelayanan Kesehatan Hewan, Bantul, Yogyakarta) and one sheep that susceptible from Cicurug, Bogor, West Java as a kontrol. Resistance status to benzimidazole was reexamined individually with LDA and FECRT before sheep slaughtered. DNA was extracted from female H. contortus worms. A fragment of 520 bp isotype- 1 β tubulin gene was amplified using Polymerase chain reaction (PCR) and then analyze using SSCP. The results showed that there were polymorphism in isotype-1 β tubulin gene among H. contortus susceptible (Cicurug, Bogor, Jawa Barat) and two H. contortus resistant strains from SPTD Trijaya, Kuningan, West Java and UPTD Pelayanan Kesehatan Hewan, Bantul, Yogyakarta. Mutation occurred in the different nucleotide of the two resistant strain.     Key Words: Haemonchus contortus, Benzimidazole, Isotype-1 β tubulin gene, SSCP

Abstract

Resistance to benzimidazole at a population of gastrointestinal nematode, especially Haemonchus contortus is a widespread problem. Therefore, anthelmintic will not effective anymore. Benzimidazole resistance in nematode has been shown to be heritable and defined as an increase in frequency of individual worms able to drug tolerate. In Indonesia resistance to anthelmintic albendazole has been reported on sheep in district of Bogor, Kuningan, Kendal and province of Yogyakarta. Molecular mechanism of resistance to benzimidazole on nematode and fungi related to single gene which code ß tubulin. The aim of this research is to determine a genetics variability of isotype-1 ß tubulin genes from Indonesian strain of H. contortus which resistant to benzimidazole. Sequencing were carried out at a 520 bp fragment of the isotipe-1 ß tubulin gene of six H. contortus resistant strain from four sheep from SPTD Trijaya farm, district of Kuningan, West Java; UPTD Pelayanan Kesehatan Hewan farm, district of Bantul, Yogyakarta respectively. One H. contortus susceptible strains as a control come from farmer from Cicurug, district of Sukabumi, West Java. Results indicated that there are genetics variability of  fragment isotype-1 ß tubulin genes from H. contortus from UPTD Pelayanan Kesehatan Hewan farm, Bantul, Yogyakarta (H1, H2, and C2). There are no genetics variability in the fragment gene of H. contortus resistant strain from SPTD Trijaya farm, Kuningan, West Java (Kn1, Kn2 and K1). Genetic variability occur between 2 isolate from different location. Key Words: Haemonchus contortus, Benzimidazole, Isotype 1 β-tubulin Gene, Sequencing

Abstract

Lymphathic filariasis that is also known as elepanthiasis is caused by infestation of 3 species nematode Wuchereria bancrofti, Brugia malayi and Brugia timori. In Indonesia 70% filariasis case caused by Brugia malayi. Mosquito species from genus Anopheles, Aedes, Culex, Mansonia and Armigeres are known as vector of this disease. Microfilaria detection on mosquito is one methode to know infection rate in vector population in endemic area.The objectives of the research were to study the ability of Hha1 repeat applicable to detect microfilaria/larvae in a pool of mosquitoes and to get description of adult mosquito night biting population lived in endemic area of filariasis brugian. Mosquito as positive control used in this research come from laboratory of parasitology of FKUI. Mosquito sample from the field was from Binawara and Kolam Kiri villages, South Kalimantan province. Mosquito were trapped then identified by its species. DNA of mosquitoes was extracted and then run by the PCR using Hha 1 repeat primer. Result of the research indicated that adult mosquitoes night biting from Binawara village consist of Culex, Mansonia, Anopheles genus and from Kolam Kiri village only from Mansonia genus. Hha 1 repeat primer is applicable to detect 1 mosquito infected with microfilaria/larvae in a pool of negative mosquitoes. Mosquito samplesfrom the two villages showing negative PCR.   Key Words: Filariasis, Brugia Malayi, Vector, Microfilaria, Filaria Larve, PCR
