2017
Yoo, J.H., National Institute of Animal Science, Rural Development Administration, Wanju, Republic of Korea | Kim, O., Wonkwang University, Iksan, Republic of Korea
At the time of visiting, the cat was 6-year-old female Siamese cat. The mammary mass was solid and firm and measured 2 x 5 cm2 in greatest diameter. The uterus revealed thick uterine horn and cross sectioned wall. Histopathologically, the mammary mass revealed feline mammary carcinoma. In the uterus, cystic endometrial hyperplasia was observed. Feline leukemia virus positive reaction was detected by polymerase chain reaction. As far as we know, this is the first report of the simultaneous feline mammary carcinoma and uterine endometrial cystic hyperplasia with Feline leukemia virus infection in a cat.

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.

A classification of raw bovine’s milk samples according to theirgeographical origin in Peninsular Malaysia by Makmal Kesihatan Awam Veterinar, Department of Veterinary Services Malaysia (DVS). Six hundred bovine milk samples were collected from Perlis, Kedah, Perak, Selangor, Pahang, Negeri Sembilan, Melaka and Johor states by 26 milkcollecting centres under DVS. This study was carried out directly using attenuated total reflectance Fourier transform infrared(ATR-FTIR) spectroscopy method coupled with a multivariate principal component analysis (PCA). The spectra generated by ATR-FTIR were analysed and regions of interest were found in between 3851.651cm-1 until 2700.819 cm-1 and 2419.173 cm-1 until 977.368 cm-1. The absorbance and wavenumber data of the regions were then analysed using PCA and the results show presence of clustering towards theirgeographical origin. ATR-FTIR coupled with multivariate PCA has potential for classifying the geographical origin of raw milk produced within Peninsular Malaysia. This method provides a rapid and nondestructive secondary methodology in milk classification without further sample preparation.

This study was conducted to observe the occurrence of aflatoxin in chicken feed from Peninsular Malaysia. A total of 336 samples of chicken feed from Peninsular Malaysia were conveniently collected in this survey. The chicken feed represented the following three categories which are starter, grower and finisher. All samples werecollected from local poultry farms in East Coast Region (Kelantan, Terengganu, and Pahang), Northern Region (Perlis, Kedah, Penang, and Perak), Southern Region (Malacca, Johor) and Central Region (Selangor, Negeri Sembilan) of Peninsular Malaysia for a periodof six months (July-December 2015). Enzymelinked immunosorbent assay (ELISA) was used for screening of total aflatoxin (TA) in the samples. High performance liquid chromatography (HPLC) with fluorescence detector was used for determination of aflatoxin B and G. Moisture content of samples was determined using the hot airoven method (AOAC International, 2011). Overall, the incidence of positive TA >20 µg/kg in chicken feed is 14.9% (50 samples). The average level of TA was found significantly different between different states at p<0.05 for both broiler grower and finisher. Thechromatograph results showed that positive samples were found in broiler finisher from Kedah (94.6 µg/kg and 42.1 µg/kg) and Penang(56.4 µg/kg) with aflatoxin B1. In this study, the range of moisture content were around 6.5-27.3%. About 40% samples have more than12% moisture content. One of the predisposing factors for aflatoxin accumulation in chicken feed is moisture content. The results warrantthe need for surveillance and constant monitoring programmes for the prevention of aflatoxin incidence in poultry farms.

2017
Maina, A. G. | Gatongi, P. M. | Nguhiu, P. N.
Human brucellosis, a neglected zoonosis is endemic in KajiadoCounty in both man and livestock. The Kajiado County community’s mainlivelihood is livestock-keeping which puts it at risk. The study objective was to determine the community’s knowledge and practices, and the association between the two in relation to brucellosis. Results revealed three predictors of practices the community undertook that put them at risk of contracting brucellosis. The predictors were respondent’s education status (p=0.002 [CI 0.272-0.749] OR 0.451), knowledge of importance of pre-purchaselivestock breeding soundness (p=0.007 [CI 1.207-3.356] OR 2.013), and knowledge that livestock abortions could result in human disease (p=0.027 [CI 1.070-2.974] OR 1.783). This meant that respondents without formal education were nearly half less likely to undertake practices that prevented transmission of brucellosis than those withformal education. Respondents who knew that livestock examination was important for breeding soundness were twice more likely to engage in practices that prevented brucellosis transmission than those whodid not know. Respondents who knew that livestock abortions could lead to diseases in man were nearly twice more likely to engage in practices that prevented transmission of brucellosis than those whodid not know that livestock abortions could lead to diseases in man. It was concluded that the community’s knowledge and practices that promote brucellosis were inadequate. Two key recommendationswere drawn. There was need to create awareness in the community on the risk factors and practices that contribute to occurrence of human brucellosis. There was need for using qualified animal health providers to mitigate the disease in animals.

Increased emergence in microbial resistance to antibiotics is a growing problem globally. A retrospective investigation was made of antimicrobial resistance in a total of 2,345 Escherichia coli isolates from clinical cases submitted to Regional Veterinary Laboratory of Bukit Tengah, Penang, Malaysia between January 2000 and December 2015. Analysis using WHONET 5.6 revealed that resistance to ampicillin, norfloxacin and aminoglycosides was detected in isolates from poultry and pigs more often than ruminants. Resistant to colistin was higher in ruminants compared to other animal groups. Nor floxacin susceptibility was very high in isolates from ruminants, pet birds (82.2%) and zoo animals (88.6%). Isolates from pet birds had higher resistant rate to all of the antimicrobials tested compared to zoo and companion animals. Multidrug-resistant (MDR) E. coli isolates (29.25%, 684/2345) were detected in this study. Further efforts, for instance, national monitoring and surveillance, are required to quantify the exposure of animals to antimicrobial agents and resistant pathogenic or commensal bacteria in the animals and also its environment. Such useful information indeed will assist the prudent use of antimicrobial agents in veterinary practice; therefore, suppress the emergence of antimicrobial resistance in animals.

2017

A study was carried out to detect and identify the presence of coccidia oocysts in the faeces of village chicken from the district of Pasir Putih, Kelantan, West Malaysia. A total of 135 fecal samples were collected from 15 areas in the Pasir PutihDistrict. The faecal samples were examined by direct smear method (qualitative study). A pinch of the faeces was put onto the glassslide with 1-2 drops of normal saline and cover slip, which was then observed under the compound microscope to detect thecoccidia oocysts. The presence of coccidia oocyst was then identified by its size and shape. Results showed that ten out of 135 samples were positive for coccidia oocysts, and classified as Eimeria maxima and Eimeria mitis, both of which are from two locations at Kampung Chap Banir, Pasir Putih, Kelantan. The remaining 125 samples were observed to be negative. This may suggest that the chickens reared in the backyard (extensive)are less susceptible to the coccidia infection due to their environment with lower stocking density (mostly free ranging chicken), and no damp/wet litter as bedding which canfacilitate sporulation of the coccicia oocyst thereby spreading the infection. Further studies need to be done to elucididate other factors which may affect coccidial infections in free range chicken such as the availability of medications in feed or genetic hardiness and tolerance to field infections. The localvillage chicken industry is an up and coming facet of the poultry industry and needs concerted efforts to boost it.

2017
Singh, C. | Sharma, A. K. | Singh, N. D. | Singla, L. D.
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.
