Masrin A. | Nurul Fatiha A. S. | Fakhrulisham R. | Sharil Azwan M. Z.
A total of 145,347 samples (4,322 cases) were received for the passive surveillance of melioidosis in the Serology Laboratory of Veterinary Research Institute (VRI) from the year 2012 to 2016. From the samples received, 0.63% were positive and 99.37% were negative. The objective of this study is to determine the seropositive rate and distribution of melioidosis in livestockbased on cases received which comprise of sheep (37.24%, n=54,130), goat (54.01%, n=78,500), cattle (8.12%, n=11,804) andbuffalo (0.63%, n=913) within the period of 5 years. A geographical mapping of seropositive cases was designed using thedata from the passive surveillance and the results were visualized in a geographical mapping which provides a clear visual description on the distribution of the diseases. By 2016, positive cases were found to be concentrated in the states on the east coast of Peninsular Malaysia and Sabah. To sum up, the percentage of seropositive cases of melioidosis in 5 years has increased from 1.79% in 2012 to 12.17% in 2015 and decreased to 1.04% in 2016. From the findings, this study can provide the dataneeded as the indicator for the evaluation of surveillance and vaccination programmes, disease eradication planning and to monitor the distribution of seropositive cases of melioidosis in Malaysia.

Chai, L. C. | Nor Ainy M. | Marni S. | Marzura M. R. | Ungku Fatimah U. Z. A. | Khairunnisak M.
The occurrence of veterinary drug residues in chicken meat originating from 320 small and medium scale chicken slaughterhouses in Peninsular Malaysia was determined. 637 chicken meat samples were examined for tetracycline (TCs), sulphonamide (SAs) and quinolone residues using a microbiological inhibition test and was further confirmed using liquid chromatography mass spectrometry (LCMS/MS). The presence of TC residues were confirmed in 10 (1.6%) samples, and 1 (0.2%)sample was confirmed in compliance to the established maximum residue limit (MRL) for residues of quinolone. A total of 6 (0.9%) samples were above the MRL for TC. The samples were from Pulau Pinang, Terengganu and Kelantan. Among those tested in compliance, the main analytes found for TC and quinolone werechlortetracyclines (CTC), enrofloxacin and mixture of chlortetracycline (CTC) and oxytetracycline (OTC). No samples were found to contain sulfonamides residues.

Suhaimi D. | Sharif S. | Normah M. A.
Palm kernel cake (PKC) has long been known to be an importantingredient for the formulation of animal feeds. However the recommended levels of inclusion seem to vary from one reporter to another. This factor is considered important especially when formulating feeds for nonruminant diets. The variation of its major constituents such as protein, fibre and fat contents is said to depend on the sources, oil removal technology and the efficiency of oil extraction from the kernel. For comparison,a set of compilation data of 300 local PKC samples from the past years on these basic nutritional constituents were studied.Majority of the samples analysed were from southern region of Peninsular Malaysia meant for animal feeds. Mean percentagevalues and their respective standard deviations were as follows; crude protein 16.1±1.65, crude fibre 19.3±4.22, crude ash5.9±2.48, ether extract 5.6±3.36, dry matter 91.3±2.65, and metabolisable energy 7.75 MJ/kg. The objective of the study was to observe the distribution pattern of these values compared to other surveys. From this study, the highest relative standarddeviation (RSD) reached 60% for ether extract, followed by ash 42.1%, and crude fibre 21.8%. From the variation point of view,periodical results for quality control of PKC must be initiated as an useful indicator for its accuracy of each diet formulation.

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.

2018
Maina, A. G. | Gatongi, P. M. | Nguhiu, P. N.
Animal-to-human brucellosis transmission methods in Kajiado NorthSub - Count y, Kenya are inadequately documented. The Sub- County’s main livelihood is livestock-keeping, putting it at risk to brucellosis infections. Objective of this study was to determine the knowledge of brucellosis among animal and humanhealth workers. These workers were stationed in Kajiado North Sub-County and were the key informants of this study from whom qualitative data was collected. The data was analysed based on emerging themes, e.g. brucellosis significance in the community, livestock birthing and milk hygiene. Results revealed that brucellosis a significant disease in the community, informants were knowledgeable on the need for pre-purchase livestock examination, the need for proper disposal of livestock abortive material and on good milk hygiene measures. However, it was found that not all had adequate knowledge about brucellosis transmission through livestock birthing. The results indicated that measures to control and prevent brucellosis transmission to man, and between animals were inadequate as health workers were unable to adequately advise the community. It is recommendedthat health workers should be trained on all methods of brucellosis transmission, especially transmission during livestock births.

Mauida, F. Hasoon, | Buktiar, Nader | Majed, H. Mohammed
Mesenchymal stem cells derived from bone marrow (BM-MSCs) havethe ability to differentiate into multiple cell lineages. Although the cultivation of these cells has led to a number of characterisation studies, some significant morphological and immunohistochemical properties are still lacking. In this study, isolation of BM-MSCs, morphological features, cell viability, immunophenotypic properties and cryopreservation of BM-MSCs wereexamined in detail. The results demonstrate that the cells isolated from BM-MSCs were plastic adherent and had fibroblastic spindle shape after three passages and get confluent monolayer cells 70-80% after 4-7 days post-subculture. Based on the cell viability analysis, the BM-MSCs showed an increase in cell viability starting from passage 1 until passage 10. Immunophenotypic analysis demonstrated that BM-MSCs were positivefor CD44 and CD105 and negative for CD34. Functional analysis of cryopreservation of BM-MSCs from P6 after 6 months expressed good proliferation rate and cell viability.

Colibacillosis is a disease caused by avian pathogenic E. coli (APEC) and is one of the principle cause of morbidity and mortality in poultry worldwide which is represented by a complex syndrome characterized by multiple organ lesions. This study was carried out to determine phylogenetic grouping and virulenceassociated genes contained by E. coli isolates which is related in causing disease in chicken. E. coli isolates obtained from clinical cases of Veterinary ResearchInstitute were re-identified by conventional methods. Phylogenetic grouping of the isolates was determined by triplex polymerase chain reaction (PCR), and the presence of eight virulence genes were identified by multiplex PCR. A total of 125 E. coli isolates were subjected toanalysis of phylogenetic background and virulence associated genes profiling. Phylogenetic analysis demonstrated that most of the E. coli isolated from chicken in this study belonged to group B1 (36.0%),group D (28.0%), group A (27.2%) and group B2 (8.8%). Multiplex PCR analysis demonstrated that 96 (78.6%) of the E. coli isolates harbored at least one virulencegene, while 29 (23.3%) did not contain any virulence genes tested. The most prevalent virulence genes identified were iss (51.2%), followed by iucD (36.0%),tsh (32.8%), vat (16.0%), astA (13.6%), irp2 (11.2%), papC (9.6%) and the least is cva/cvi gene (0%). None of the isolates harbored more than four virulence genes.Each of phylogenetic groups presented with different combinations of virulence genes, with no specific combinations of virulence genes found to correlate withE. coli phylogroups. None of the E. coli isolates harbored more than four virulence genes, suggesting that E. coli isolates from chicken in this study appear to bederived from commensal strains and may relate to environmental predispose factors especially stress factors in the host to establish infection.

A study was carried out to report the phylogenetic analysis of Brucella abortus and Brucella melitensisby using molecular techniques from samples submitted to the Regional Veterinary Laboratory, Bukit Tengah.In this study, identification and genetic characterization of Brucella isolated samples using molecular analysis based on IS711 sequence between localisolates and foreign countries accesses in GenBank was done successfully. A total of 31 samples were isolated for Brucella species and then were amplified byPCR, directly sequenced and compared genetically to published sequences which were obtained from GenBank. The most common Brucella species that was found in both bovine (76.5%) and caprine (85.7%) through diagnostic samples in Regional Veterinary Laboratory, Bukit Tengah, was Brucella melitensis. PCR and sequencing were confirmed positive with 76.5% for Brucella melitensis, 23.5% for Brucella abortus and 23.5% for mixed infectionfrom the total of 17 bovine samples. In caprine, the detection of Brucella melintesis and Brucella abortus showed 85.7% and 21.4% respectively meanwhile total mixedinfection showed 21.4%. These clustering between local isolates of Brucella melitensis were phylogenetically related to other Asian countries such as Singapore,Yemen and Saudi Arabia. The Neighbour Joining Analysis clustered the Brucella abortus local isolates for both bovine and caprine were most closely related to India,Iran, Italy and USA. Interestingly, all the isolates within Malaysia have a close relationship (>95%) with the low level of genetic diversity. When local isolates arecompared to GenBank data, it gives an indication on the possible sources of these infections. Eventually, it will improve the import and export policies to controlbrucellosis in Malaysia.

Salmonella is known as one of the important food-borne pathogenthat causes salmonellosis in human and animals worldwide. A prevalence study on salmonellosis was conducted on wild rats in Kelantan. From April to June 2015, a total of 36 rats and house shrews sent to the Regional Veterinary Laboratory in Kota Bharu, Kelantan were examined for the presence of Salmonella. These animalswere caught from various locations in the state and were sent to the laboratory either as live or dead specimens. Post mortem wasconducted and intestines were taken for detection of salmonellosis. Results showed that of the 32 rats and 4 shrews examined, 5 (15.6%) rats and 3 (75%) shrews were found positive and on serotyping fourserotypes of Salmonella were identified which are Salmonella ser. Kalamu (62.5%), Salmonella ser. Thyphimurium (12.5%), Salmonella ser. Weltevreden (12.5%) and Salmonella ser. Brancaster (12.5%). In conclusion, positive identification of Salmonella in wild rats indicates that there is a possible transmission of the pathogento humans due to constant contact between the two. Thus appropriate measures are needed to control these pests population to prevent spread of diseases to the humans and animals.
