Stress factor causing death in Sambar deer (Cervus unicolor)
2018
Donny, Y. | E. Sivananthan T. | Santhi, M. | Hanis Iryani I. | Siti Aminah A. | Rozza Nadiah R. | Khairil Azman Z. A.
An adult female Sambar Deer (Cervus unicolor) at Wildlife Conservation Centre, Sungkai, Perak was found dead in the paddock after abortion. The dead foetus was found on the paddock the day before this incident. The workers at the conservation centre also reported that the doe was attacked few times prior to death by a bull of the same group. The paddock in the Sungkai Conservation Centre was under construction and it was suspected that the noise from heavy machiner y and animals being transferred into different paddocks caused further stress to the affected doe which led to abortion and death. Post-mortem lesions showed generalised congestion and haemorrhage of all vital organs including liver, heart, lungs, kidneys and spleen. Histopathology revealed all organs have evidence of generalised congestion. Cause of death in this case is failure of the body system due to generalised congestion of the vital organs due to stress factor.

Ayad, Abdelhanine | Benhanifia, Mokhtar | Benbarek, Hama
The present study describes the use of electrochemiluminescenceimmunoassay (ECL) with the specific human kit for measuring plasma testosterone and progesterone in ovine. This study wascarried out on 16 mixed age animals of the local breed. They were divided into two groups of both sexes, namely Male-1 Group,Male-2 Group, Female-1 Group and Female-2 Group. Blood samples were collected from the jugular vein into tubes containing EDTAand centrifuged at 1500 rpm for 20 min. Plasma was rapidly separated and stored at -20° C until assayed. The reproducibilityinter- and intra-assay of the P4- and T-ECL is satisfactory (2.11-7.3 %). The accuracy (93-102 %) and the test of parallelism were largely acceptable. No cross-reaction was observed with the different hormones including PMSG,hCG, progesterone,testosterone, oxytocin and PGF2α when concentrations of 10 UI/ml and 10-3 UI/ml were used. T concentrations were higher in Male-1 Group than in Male2 Group (1.67 ± 1.15 and 0.38 ± 0.45 ng/ml, respectively). The female-1 Group showed very high P4 concentrations (15.17 ± 4.91 ng/ ml) compared to the Female-2 Group (0.08 ± 0.04 ng/ml). The results obtained clearly show that human ECL system can be used to measure progesterone and testosterone in plasma ovine

2018
Agbajelola, V. I. | Lawal, I. R. | Falohun, O. O.
Zoonotic parasitic gastroenteritis has been well-known as a serious limitation to humans as well as livestock productivityin terms of man-power, pathology and fiscal losses, as human infection with these helminths from cattle can resultfrom consumption of meat containing the infective stage of the worm. This study therefore investigates the presence ofzoonotic helminth infections among cattle in Minna metropolis, and scientific basis for their potential transmission to humanpopulation. A total of 184 diarrhoeic faecal samples from cattle were collected from September 2014 to June 2015 in Minna,Niger state and processed using the direct faecal microscopic examination techniques. The obtained results showed that a total of 81 (44%) samples were positive including Ascaris sp, Fasciola gigantica, Trichuris sp. and Taenia sp. with infection rates of 22.3%, 12%, 2.2% and 0.5% respectively, and mixed infections of Fasciola gigantic with Ascaris sp. (4.3%) , and Ascaris sp. with Trichuris sp. (2.7%). Poor human hygiene, inadequate livestock husbandry managements and restriction of animals to residential areas are the major factors responsible for the high prevalence of zoonotic helminths and geo-helminths in the study area. Therefore veterinarians, animal handlers and livestock owners should practice personal hygienic and safe management practices for animal rearing and treatments.

2018
Tarik Ibrahem Ali | Omar Emad Ibrahim | Imad I. Al-Sultan
A rare case is presented of a 58-year-old woman who developed ahepatic-bronchopleural fistula following a hydatid hepatic cyst complication. The hepatic-bronchopleural fistula was diagnosed when patient complained of severe repetitive attacks of productive cough of brown yellow to dark colour sputum biliptysis (bile in cough) with vomiting associated with night sweating and fever, for the past one month. She also complained of right side chest and abdominal pain for the past 3 years. This paper describes a unique case of hepatic-bronchopleural fistula caused by hydatid disease, emphasising the clinical feature and its surgical management. Hydatid disease is a zoonotic infection dueto the damage caused by Echinococcus granulosus. E. granulosus, also called the hydatid worm, hyper tape-worm or dog tapeworm, is a cyclophyllid cestode that parasitises the small intestine of canids as an adult, but which has important intermediate hosts such as livestock and humans, where it causes cystic echinococcosis, also known as hydatid disease. It is hoped thatthis case report will add to the meagre case management reports of hepaticbronchopleural fistula in literature.

2018
Zubaidah, M. A. | Tariq J. | Nur Raihan M. A. | Abd Halim H.
Highly pathogenic avian influenza (HPAI) is caused by influenza virus A from the family Orthomyxoviridae. It is a severe, systemic disease with high mortality in avians. The mortality can be as high as 100% in a few days. On 28 February 2017, HPAI virus of H5N1 subtype was confirmed in village chickens at Kampung Pulau Tebu, Batu 5, Tunjong Kota Bharu, Kelantan. It wasthe second outbreak of HPAI in Kelantan after the first reported case at Tumpat Kelantan on 17 August 2004. Most of the dead poultry showed similar clinical signs of sudden death with high mortality, cyanosis and oedema of head, comb, wattle and snood as well as red discolouration of shanks and feet. Post-mortem was performed on dead poultry and there were generalised haemorrhages of all internal organs, congested mesenteric blood vessels andpinpoint haemorrhages on proventriculus. Histopathological examination revealed generalised pulmonary haemorrhages with moderate interstitial pneumonia, generalised hepatic haemorrhages and hepatitis with multifocal area of hepatic necrosis, generalised haemorrhagic myocarditis and generalised haemorrhagicnephritis. Confirmation test was performed using RT-PCR and viral isolation at Veterinary Research Institute, Ipoh. 36 foci wereaffected involving five districts (Kota Bharu, Tumpat, Bachok, Pasir Mas and Tanah Merah) causing depopulation of 56,953 poultryand 17,531 eggs. Surveillance and control measures were taken by Department of Veterinary Services to contain the disease from spreading to other areas.

2018
Wan Norulhuda W. A. W. | Norhartini I. | Tariq J.
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.

Infectious diseases of livestockare a major threat to global animal health and welfare and their effective control is crucialfor agronomic health, for safeguarding and securing national and international food supplies and for alleviating rural povertyin developing countries. Some devastating livestock diseases are endemic in many parts of the world and threats from old and new pathogens continue to emerge, with changes to global climate, agricultural practices and demography presenting conditions that are especially favourable for the spread of arthropod-borne diseases into new geographical areas. Zoonotic infections that are transmissible either directly or indirectly between animals and humans are on the increase and pose significant additional threats to human health and the current pandemic status of new influenza A (H1N1) is a topical example of the challenge presented by zoonotic viruses (Tomley and Shirley, 2009). Malaysia, being one of the members of the World Organisation forAnimal Health (OIE) which is responsible for setting standards for control of animal diseases. For year 2017, the list included 116 animal diseases, infections and infestations, many of which are zoonotic in nature. As such, this paper discusses the commonzoonotic infections diagnosed in the five Regional Veterinary Laboratories which are spread across the country and entrustedto carry out diagnostic tests to aid in the treatment and control of animal diseases. A total of almost half a million samples weretested comprising more than a million tests to help the Department of Veterinary Services control and eradicate economically important diseases to safeguard the animal population. Of these, zoonotic diseases comprise a small but significant entity which needs careful attention (Chandrawathani et al., 2017) Dora Tan (1981) reported that among the many zoonotic diseases prevalent in Malaysia, are leptospirosis, rabies, influenza, Japanese encephalitis, toxoplasmosis,ornithosis, Q fever and monkeypox which have been investigated at the lnstitute for Medical Research, Kuala Lumpur. The regional laboratories have full capability to conduct tests to confirm parasitic, viral and bacterial infections except for rabies andavian influenza, which was diagnosed in the Veterinary Research Institute. However, preliminary tests for avian influenza wascarried out in regional laboratories.

2018
Suriaty R. | Mohd Hafiz A. R. | Halimaton Sa’adiah T. | Zawawi I.
Malin sheep is the indigenous sheep breed of Malaysia and mainlykept for meat production. A total of 48 individuals from the National Institute of Veterinary Biodiversity (NIVB) in Jerantut,Pahang were used. The objective of this study was to assess the genetic diversity in the Malin using microsatellite markers.Eleven microsatellite loci were successfully amplified in 48 Malin sheep. All loci were polymorphic. A total of 66 alleles were detected. The number of observed alleles per locus varied from 12 to 21, with mean observed number alleles per locus of15.18±4.58. The observed heterozygosity and expected heterozygosity were 0.0189±0.01 and 0.8989±0.01, respectively. The mean polymorphic information content (PIC) value was 0.8970±0.01, indicating that the used markers were highly informative and could be used in parentage identification. Tests of genotype frequencies for deviation from the Hardy-Weinberg equilibrium (HWE), at each locus revealed depature from HWE due to loss in heterozygotes by high levels of inbreeding. The average inbreeding value for the 11 markers investigated was0.9797±0.01 indicating a more homozygous nature of the population. This is the first report of microsatelitte based variations in Malin sheep breed and can be useful for development of a rational breeding strategy for genetic improvement of sheepin Malaysia which may benefit future conservation programmes.

2018
Adenkola, A. Y. | Adah, A. S. | Azeez, O. M.
This study was done to assess oxidative stress and haematologicalparameters of twenty male goats aged between eight and 22 months of the West African Dwarf breed reared under twomanagement systems. Ten bucks were reared under an intensive system, and another 10 bucks reared under an extensivesystem were used. The Hb concentration obtained in both groups was significantly (p<0.05) higher in the intensively managedgoats (12.39±0.02 gm %) compared to the extensively managed group. The total erythrocyte count in intensive goats, 35.34±1.36×106/μl, was significantly (p<0.05) higher than the value recorded in the extensive group (30.01±1.41×106/μl). Therecorded leucocytes counts in intensive goats of 10.26±0.70×103/μl was significantly (p<0.05) lower than 12.38±1.23×103/μlrecorded in the extensively managed goat, while the calculated value of MCV in intensive goat (9.8±0.73 fl) was significantly(p<0.05) higher than the recorded value in extensive group. The obtained value of MCH was significantly higher (p<0.05) in theextensively managed goats. The recorded neutrophil value of 5.00±0.50×103/μl in extensively raised goats was significantly(p<0.05) higher than 3.70±0.20×103/μl obtained in the intensively raised group likewise the lymphocyte count of 5.60±0.08 ×103/μl in intensively raised goats was significantly (p<0.05) lower than the value obtained in the extensively raised goat. The neutrophil:lymphocyte ratio was significantly higher (p<0.05) in the extensive versus the intensive group viz. 0.75±0.03 asagainst 0.67±0.04. In the extensive group a higher malondialdehyde (MDA) value of 2.30±0.07 ng/ml was recorded and this was significantly (p<0.05) higher than the corresponding value of 1.28±0.11 ng/ml obtained in the intensively managed goats. The recorded value of superoxide dismutase, catalase and glutathione peroxidase was significantly (p<0.05) higher in theextensive group than those on the intensive group. The fragility test of the extensively managed goats shifts more towards rightand was significantly (p<0.05) highest at a sodium chloride concentration of 0.2-0.7% in extensively managed goats. It can beconcluded from the present study that the biomarkers of oxidative stress were higher in the extensively than the intensively managed goats.
Afficher plus [+] Moins [-]Influence of applying effective microorganism (EM) in controlling ammonia and hydrogen sulphide from poultry manure
2018
Nurzillah M. | Norfadzrin F. | Haryani H.
Poultry layer houses are mostly open house system that generally faced with flies and odour and has become nuisance factors to society and the environment. This study was aimed to determine the effectiveness of applying EM in controlling pollutant gas emission at poultry layer house. A commercial poultry layer farmwas selected. Two treatments were carried out, the control without any application of microorganisms and the treated group with commercial microorganism application. Atmospheric ammonia and hydrogen sulphide were measured using a special instrument called ‘multi-gas detector’. The levels of ammonia and hydrogensulphide were measured twice a week. Odour production cannot be completely prevented on a farm. Therefore, most odour control methods are designed to keep or dissipate odours within the farm boundary, thus minimising odour complaints from surrounding neighbours. This paper reports that applying of effective microorganisms into the manure showed some positive influence in controlling atmospheric ammonia levels.
