This report describes atypical chronic trypanosomosis in a three year male Spitz dog. Fever, lethargy and anorexia were the early presenting signs without any hemato-biochemical abnormality. Peripheral blood smear examination was non-diagnostic on three consecutive times. Trypanosma evansi was confirmed in the Leishman stained thin blood smears (moderate parasetemia) on fourth parasitological examination. Biochemical profile showed a remarkable elevation in total serum bilirubin (6.7 mg%) and activities of alanine amino transferase (ALT) (950 IU/L) and alkaline phosphatase (AKP) (1050 IU/L) after a month. Anemia, leucopenia, neutropenia, lymphopenia and thrombocytopenia suggestive of bone marrow depression appeared by about 73 days of presentation of case. A rapid complete clinical recovery occurred within a week after treatment with quinapiramine sulphate and chloride combination @ 3.5mg/kg bwt. Hemoglobin, leucocyte and thrombocyte count improved within six days, however, liver enzyme activity normalized slowly over three months.

Wild rats are known as a major reservoir and intermediate host for several pathogenic microbial species. Thus, theVeterinary Research Institute (VRI) conducted a survey to determine the presence of parasitic pathogens in local rats, such as blood protozoans, gastrointestinal parasites, as well as ectoparasites such as mites and lice. The study was conducted with the collaboration of Kuala Lumpur City Council Pest Control Unit, whereby a total of 105 wild rats were trapped at two urban areas of Kuala Lumpur; namely PasarPudu and Chow Kit. Autopsy was done on the rats to acquire the skin, organ and blood samples..The skin scrapping was performed on skin samples to identify the common species of mites and lice, while the floatationtechnique was conducted on faecal samples to identify helminth eggs. Results showed thatspecies of Tritrichomonas, Strongyloides, Nippostrongylus, Blastocystis, Rodentolepis, Coccidia, Trichuris, Capillaria and Ascarid were found in the faeces while Trypanosoma sp.was found in the blood samples taken from the animals. Taeniataeniformis was obtained from liver samples while theectoparasites found on skin were identified as Radfordia,Polyplax,Linognathus and Hoploplurasp. Control and eradication of rodent pests is crucial in combating emerging and re-emerging diseases which may be zoonotic as rodents are reservoirs to various pathogens.

Septicaemic pasteurellosis is a fatal, sometimes epidemic, bacterial disease of domestic and wild animals including deer, bison, elk, and pronghorn antelope caused by Pasteurella multocida. This is the case report of septicaemic pasteurellosisin a captive sambar deer. The carcass was sent from Royal Endurance Stable, Bachok, Kelantan to the Kota Bharu RegionalVeterinary Laboratory for post-mortem. Gross examination of organs was followed by collection of specimens from lung, kidney,liver, spleen and heart for histopathology and bacterial examination. Pooled organ samples with rumen content were collected and sent to the nearest Chemistry Department for investigation. For histology, the liver, lung, spleen, kidney, and heart specimens were fixed in 10% neutral formalin, and routinely embedded in paraffin. Fivemicrometer sections were stained with H&E. Other tests such as worm and ectoparasiteidentification were conducted to identify the parasites. Post-mortem lesions revealed generalised haemorrhage in the organs.Pasteurella multocida serogroup B and E. coli were isolated from multiple tissues of the animal. Histological examination alsorevealed severe congestion and haemorhage of multiple tissues with infiltration of the inflammatory cells. The most likely mode of transmission of these bacteria is through an infected wound and into the bloodstream, thereby causing severe septicemia and death to the animal.

Goose Parvovirus (GPV) also known as Derzy’s disease is aninfectious viral disease of waterfowl which causes serious economic loss in industrial production of geese and Muscovy ducks. In year 2014, Derzy’s disease was detected in Pekin ducks from Sarawak. The affected farm recorded up to 50% mortality, affecting only young ducklings (starting at the age of 3 weeks). Polymerase chainreaction (PCR) from liver samples were performed based on partial region of VP3 gene of GPV, generated amplicon of 801 bp. Sequence analysis showed that the isolate shared 99% sequence similaritywith goose parvovirus strain YBLJ and YZYZ20130304 from China. Phylogeny based on VP3 showed that this isolate is grouped under Asian strains. This is the first report of GPV in Malaysia focusingon the molecular analysis. Notably, this study revealed that GPV not only can be detected from goose and Muscovy but also from Pekin duck.

This report describes the parasitological and pathological information retrieved from the samples submitted to Regional Veterinary Laboratory, Bukit Tengah, Penang (MVKBT) followingan episode of histomoniasis in a small scale poultry farm. Liver and ceca from two dead turkey birds, water (n=5) and freshwater snails (Pomacea sp, n=7) were stored between 4°C to 10°C until analyzed. Soil samples (n=7) were preserved in 5% formalin and kept at room temperature prior to further testing. The soil samples were filtered through laboratory test sieves before the filtrates at each level were examined using direct microscopy. Portions of the liver were processed using routine paraffin technique for histopathological examination and found positive for Histomoniasis. Results from direct microscopy of the liver samples revealed Schistosoma mansoni ova, Sarcocystis sporocysts and Fasciola sp. Heterakis sp ova were detected from cecal content. Four out of seven soil samples were positive for Sarcocystis sporocysts, Coccidia oocyst, Strongyles ova and nematod larva. Water and freshwater snail samples were negative for cercaria of Schistosoma mansoni. This case was concluded as Histomoniasis, Sarcocystosis and helminthiasis with incidental finding of Schistosoma mansoni.

A total of thirty snakehead fishes Channa micropeltes (Cuvier, 1831)
were collected at Tasik Kenyir, Malaysia. Muscle, liver, intestine and kidney tissues were removed from each fish and the intestine was opened to reveal cestodes. The cestodes were identified on the basis
of their morphological characteristics. After staining, drawing by using Camera Lucida, measurement by using advanced microscope and using Scanning Electron Microscope (SEM), the results showed that
the cestode was Senga parva (Fernando and Fertado, 1964). It differed from other species of genus Senga, parasitising fish genus Channa, by the size of the strobila, scolex, apical disc, hooks, number of hooks, testes and some other characteristics.
