A total of 23,322 specimens collected between 2014 and 2017, froma total of 2,592 cases, were received in Veterinary Research Institute, Ipoh (VRI) from various states in Malaysia and testedfor common bacterial, viral, and parasitic diseases in pigs. The highest occurrence of isolated bacteria from 771 samples whichtested positive were Salmonella (47.38%) and Escherichia coli (15.68%), followed by Staphylococcus (6.62%), Streptococcus (5.57%), Klebsiella pneumonia (4.88%), Pseudomona (3.38%), Acinetobacter (3.14%), Aeromonas (2.79%), Enterobacter (2.44%), one each of Bacillus and Pasteurella multocida (1.74%), Enterococcus (1.39%) and Corynebacterium (1.05%). 1.74% of each bacteria detected were Moxarella, Aspergillus, Burkholderia andChromobacterium. Positive samples tested by ELISA was Japanese encephalitis virus (JEV) (9.15%), Aujezsky disease virus (ADV)(5.37%), porcine cirvo-virus-2 (PCV2) (5.09%) and porcine reproductive and respiratory syndrome virus (PRRSV) (4.52%). Positive amples tested by the molecular test wasPCV2 (1.62%), PRRSV (1.32%) and classical swine fever virus (CSFV) (0.4%). Serology tests were conducted on 11,305 samplesand reported positive for Brucella suis (15.32%), Brucella abortus (0.62%), Brucella melitensis (0.85%), and melioidosis (0.05%). Parasitology analyses on 99 samples. revealed presence of 10.1% coccidia and 1% each of helminths and Sarcocystis. Within the 4-year period, there were no positive samples for porcine parvovirus (PPV), Nipah virus, swine influenza virus (SIV), and bacteria of Johne’s disease and leptospirosis. Continuous assessment is required to establish a comprehensive baseline data of swine diseases in Malaysia.

Trypanosomiasis positive cases were reported in Sahom Farm Retreatin Gopeng, Perak; with multispecies livestock animals. Nzi and Vavoua traps were applied to survey the population of biting flies; stable flies (Muscidae: Stomoxyinae) and horse flies (Tabanidae)as the vector for surra. Results indicated the presence of Trypanosomiasis infection diagnosed by buffy coat examination, thinblood stained smears and serological test (Surra Sero K-Set test) and identification of its insect vectors. The presence of bothbiting flies provides the missing link between the occurrence of the disease and host or environmental factors precipitatingthe disease. Besides trypanosomiasis in cattle, other parasitic infections were also recorded with heavy infections for liver fluke (Fasciola gigantica ova) and coccidia oocysts. Therefore, some control measures are recommended to eradicate the vectors and to treat infected animals in order to prevent the dissemination ofthe trypanosmiasis.

A study was conducted to identify the current status of Fasciolaand Paramphistomum infections in small ruminants in Terengganu. A total of 267 faecal samples from small ruminants were collected and subjected to sedimentation technique. Serum samples were diagnosed for detection of IgG antibody for Fasciola infection using sELISA method. Results showed that there were 4% of the goats positive with Paramphistomum eggs whereas Fasciola egg was not observed in any of the faecal samples. However, it was found that 89% of the serum samples from goats were positive with IgG antibody for Fasciola infection. Small ruminants in Terengganu were not infected with severe Fasciola and Paramphistomum infections yet the results obtained from this study will update the current status of the infections. This information will help the farmers and the Department of Veterinary Services to plan on management to maintain the animals’ health.

A total of 3430 serum samples from various animal species and humans were tested using microscopic agglutination test (MAT) to determine
the frequency of the important leptospiral serovars involved in animals and humans. The sera were screened against 14 serovars of pathogenic Leptospira interogans and 1 serovar of non-pathogenic Leptospira biflexa. Altogether, 441 (12.86%) of the tested serum samples were found to be positive serologically. Tested sera reacted to all 15 serovars used in this study. The most predominant serovar in cattle and sheep is hardjo (39.60% and 66.67%). However, in goat, buffalo and horse, the most frequent serovar detected is hebdomadis (30.00%, 32.58% and 57.14%). In dog, the most predominant serovar is bataviae (19.23%). In humans, the most predominant serovar is cynopteri (3.26%). Among all the samples tested, there were no positive samples from pig and cat. Domestic animals, rodents and
pets can infect the environment or transmit the disease to human or other animals. This study showed that domestic animals could play a role in the epidemiology of leptospirosis and represents a threat to
public health.
