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.

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.

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.

Khoo, E. | Siti Nor Hanani R. | Fhitri M. | Rosnah Y. | Nafizah M. | Noormah M. A. | Khoo, L. L. | Roseliza R. | Saifu Nazri R. | Zamila Z.
A total of 65 Pasteurella multocida were isolated and identified from various animal’s samples received by Veterinary Research Institute (VRI) during the period of 2014 to 2016. These animals comprises of cattle, goat, pig, chicken, duck and rabbit. The serogroup of Pasteurella multocida were carried out using designation system of Carter’s capsular typing and molecular serogrouping method. Based on cases submitted to VRI, the prevalence of pasteurellosis in Malaysia ranging from 1.0% to 3.2% (2014 to 2016). It is low compared to previous reports and the pattern of predominant serogroups and animal hosts were found to be changing every year. In 2014, 80% (12/15) of the isolates were Pasteurella multocida Carter’s type D where all were isolated from goats. In 2015, the predominant serogroup changed to Pasteurella multocida Carter’s type A with a prevalence rate of 40.6% (13/32) which were mostly isolated from duck and cattle. While for Pasteurella multocida Carter’s type D, the prevalence in 2015 reduced to 21.9% (7/32) compared to the previous year and it was isolated from various animal species. Interestingly, in 2015 there was one isolate of Pasteurella multocida Carter’s type B isolated from goat with no reported history of outbreak. In 2016, the prevalence of Pasteurella multocida Carter’s type A increased to 72.2% (13/18), with a high percentage (92.3%) infection in young calves showing clinical signs with high mortality and morbidity in infected farms. Furthermore, during these 3 years of study, 3 isolates of Pasteurella multocida serogroup F were also identified each from pig, goat and chicken, respectively. In conclusion, this study revealed that pasteurellosis had become sporadic in Malaysia and the distribution of serogroups were diverse in all species of animal with no definitive host.

Zubaidah M. A. | Tariq J. | Mohd Daud Z. | Mahazan M. S.
In Peninsular Malaysia, footand-mouth disease (FMD) has been reported since early 1860 which then became sporadic, causing outbreaks every year. Since then, Peninsular Malaysia has become endemic with FMD. The aim of this study is to provide findings of the current FMD occurrence and its serotyping in Peninsular Malaysia. An identification of Foot and Mouth Disease serotype was carried out in Peninsular Malaysia by the Regional Veterinary Laboratory Kota Bharu (RVLKB) only. Epithelial tissue samples were received from 10 states throughout Peninsular Malaysia from 2012 until 2016. Indirect sandwich ELISA was performed using ELISA kit for FMDV antigen detection supplied from the Institute for Animal Health, Pirbright Laboratory. All findings and results in this paper were based on samples received by RVLKB and does not reflect overall cases reported to State DVS or to DVS Malaysia. From the results, 2013 had the highest samples positive for FMDV (35% from 43 samples), followed by 2014 (31% from 80 samples), 2012 (24% from 122 samples), 2015 (21% from 39 samples) and the lowest is 2016 (17% from 194 samples). The FMDV serotypes detected throughout 2012 to 2016 from 110 positive samples were Serotype O (80%), followed by Serotype A (20%) and none from Serotype Asia 1. Strict regulation, FMD vaccine evaluation by LPB ELISA and strict animal movement shall be considered to achieve FMD free for upcoming Year 2020.

اظهر المزيد [+] اقل [-]Ignorance as a factor influencing the prevalence of onchocerciasis in some villages in Oyo State, Nigeria النص الكامل
2017
Akinboade, O. A. | Anong, C. I. N. | Uwalaka, E. C.
Most studies on Simulum damnosum in Nigeria has focused mainly on the problem of onchocerciasis from the ecological standpoint. However, this study is aimed at viewing it from the human angle, with focus placed on the ignorance of the rural dwellers about the influences of their environment on the increasing incidences of onchocerciasis in their population. The premise is that, as the government and the scientists are working towards finding a lasting solution to the epidemic, the rural dwellers need to wake up to the realities of their own destiny. They need to come out and collaborate with other good efforts to form a strong united force that will rid their society of this menace. A study on the level of ignorance was carried out. It is assumed that their ignorance has kept the villagers relatively inactive and passive about freeing themselves. A descriptive method was used for this research and about 450 villagers were randomly selected and verbally interviewed. A questionnaire was designed and used as the instrument of the research. The research was carried out in two different villages of Asejire and Asepari. Findings were encouraging. Some of the villagers did not know about the existence of the disease even when some of their close relatives showed the symptoms. This high level of ignorance shows that it will be difficult to attain any cooperation from them in any attempt to make their environment unfavourable for the vector.
