This study was done to evaluate the status of resistance to nematode populations on four major groups of anthelminthics. Nematode faecalegg count reduction tests (FECRT) were conducted on six free grazing small holder goat farms (namely Farms A-F) in Perak.The four drug groups tested in this study were Benzimidazoles, Imidazothiazoles,Macrocyclic Lactones and Salicylanilides. Faecal samples were subjected to the standard procedures of McMaster for worm egg estimation and also larval cultures for third stage larvae identification. Results of Farm A, Farm C and Farm D showed resistance to all 4 drugs groups of anthelminthic that were tested and the major worm population of this farm were Haemonchus contortus (49.75%), Trichostrongylus colubriformis (47.71%) and Cooperia sp. (2.53%). The results of Farm B and Farm F showed resistance to all the 3 groups of anthelminthics except Levamisole and the worm population of this farm was Haemonchus contortus (47.30%), Trichostrongylus sp. (38.44%), Oesophagostomum columbianum (13.50%) and Cooperia sp. (0.76%) Farm E was resistant to Benzimidazoles andsuspected resistance to 3 drugs groups; Levamisole, Macrocyclic Lactones and Closantel. The worm population for Farm E was Haemonchus contortus (71.35%), Trichostrongylus sp. (27.6%) and Oesophagostomum sp. (2%). These farms have a history of using the same anthelminthics over the past few years, thus leading to the severe case of anthelminthic resistance. Recommendations have beenmade to control helminths using alternative approaches such as cut and carry feeding, herbal medication using Neem leaves (Azadirachta indica) and rotational grazing as well as improvement in management of animals to increase their immunity.

Limited information is available regarding gastro-intestinal (GI)parasitic infections in Malaysian swine populations. Hence, the present study aims to determine the prevalence of GI parasites in two swine populations in Malaysia, using formalin-ether concentration technique. In the present study, three helminths and two protozoa were detected in 91 swine rectal fecal samples. The zoonotic transmissible protozoan, Balantidium coli (22.0%) had the highest infection rate, followed by strongyle (4.4%), Entamoeba spp. (2.2%), Fasciolopsis spp. (1.1%) and Trichuris suis (1.1%). The co-infection between T. suis and B. coli was also found in this study.

A case of a cestode parasite (Choanotaenia infundibulum) egg wasfound in the intestine of chicken which was sent to the Veterinary Research Institute, Ipoh in February 2014 for post-mortem. Other parasites found in the intestine were adult tapeworm and oocyst ofcoccidia. The examination of the chicken intestine for helminth ova was undertaken using direct examination of a simple wet smear of the intestinal content which was observed under compound microscope.The cestode parasite was identified based on helminthological keys by Soulsby, 1982.
