Proventricular dilatation disease (PDD) is caused by avian bornavirus (ABV) has been identified in psittacine, non-psittacine birds and waterfowl. Birds may show signs of gastrointestinal tract deficit or neurological dysfunction or even both. The objectives of this study were to determine the molecular prevalence, risk factors and public awareness of ABV and PDD among captive and non-captive birds in Peninsular Malaysia.

Schmallenberg virus (SBV) is an emerging arthropod-borne pathogen of domestic and wild ruminants responsible for devasting economic losses in European countries with a potential for spreading across boundaries. Three hundred sixty-two (362) serum samples were randomly collected from 7 selected sheep and goat farms from January to October 2019 to investigate the seroprevalence of SBV among small ruminants in Negeri Sembilan and Terengganu states. Seroprevalence of SBV was determined using commercial ID vet® SBV multispecies cELISA test. The farmers completed a structured questionnaire to furnish farm management data to evaluate the risk factors associated with the seroprevalence of SBV among individual animals. A Chi-square test was performed to determine the association between seroprevalence of SBV and putative risk factors of individual animals. Based on the ELISA test, a total of 78 individual animals were seropositive with an overall prevalence of 21.5% and the true prevalence of 22.1% (95% CI:18.06-26.71). Multivariable logistic regression analysis further revealed that Negeri Sembilan state (p<0.001; OR=14.290; 95% CI=5.384-37.930), Breed: Malin sheep (p<0.001; OR=20.453; 95% CI=4.807-87.022), Barbados Black Belly sheep (p<0.01; OR=69.947; 95% CI=16.819-290.901), Boer goat (p<0.001; OR=9.108; 95% CI=3.191-25.997) and crossbred goat (p=0.001; OR=4.964; 95% CI=1.905-12.934) are risk factors of SBV among individual animals. This study highlights the prevalence of a new transboundary disease among small ruminants in Malaysia. The result obtained here provides preliminary data that could guide livestock producers and policy makers in designing suitable prevention and control measures.

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.

A study carried out on the presence of parasites, both internal andexternal, in 29 stray and 38 pet dogs in Ipoh, Perak indicated that four species of ectoparasites and four species of endoparasites were identified. Samples collected were diagnosed at the VeterinaryResearch Institute (VRI) whereby it was found that a higher percentage of stray dogs were infected (76%) with parasitesas compared to pet dogs (16%) that were presented at the government veterinary clinic. Parasitic infections in dogs are especially important as Demodex sp., Giardia sp., Toxocara sp. and Ancylostomasp. are zoonotic and can cause skin infections, mange, diarrhoea and anaemiain humans. Regular screening of pets is important to stave off unwanted infections. As for stray dogs, strict enforcement tocontrol stray dog population and public awareness campaigns on uncontrolled breeding of dogs needs to be emphasised.
