A four period cross-over blinded study was conducted in eight healthy beagle dogs of both genders. Read More

    Performance, biochemical and haematological responses, and relative organ weights of laying hens fed diets supplemented with prebiotic, probiotic and synbiotic.
    BMC Vet Res 2017 Aug 17;13(1):248. Epub 2017 Aug 17.
    Laboratory of Vaccines and Immunotherapeutics, Institute of Bioscience, Universiti Putra Malaysia, 43400 UPM, Serdang, Selangor Darul Ehsan, Malaysia.
    Background: The increasing trend of ban on the use of antibiotic growth promoters (AGPs) across the globe in the poultry industry has led to a growing need for alternatives to AGPs. Prebiotic, probiotic and their combination as a synbiotic have been considered as potential alternatives. This study aimed to investigate the effects of a prebiotic (isomaltooligosaccharide, IMO), a probiotic (PrimaLac®), and their combination (synbiotic) on hen performance, biochemical and haematological responses, and relative organ weights from 20 to 52 weeks of age.

    Blood acid-base status in impala (Aepyceros melampus) immobilised and maintained under total intravenous anaesthesia using two different drug protocols.
    BMC Vet Res 2017 Aug 16;13(1):246. Epub 2017 Aug 16.
    Department of Paraclinical Science, Faculty of Veterinary Science, University of Pretoria, Private Bag X04; Onderstepoort, Pretoria, Gauteng, 0110, South Africa.
    Background: In mammals, homeostasis and survival are dependent on effective trans-membrane movement of ions and enzyme function, which are labile to extreme acid-base changes, but operate efficiently within a narrow regulated pH range. Research in patients demonstrating a pH shifts outside the narrow regulated range decreased the cardiac output and systemic vascular resistance and altered the oxygen binding to haemoglobin. These cardiopulmonary observations may be applicable to the risks associated with anaesthesia and performance of wildlife ungulates on game farms. Read More

    OmpA protein sequence-based typing and virulence-associated gene profiles of Pasteurella multocida isolates associated with bovine haemorrhagic septicaemia and porcine pneumonic pasteurellosis in Thailand.

    Department of Genetics, Faculty of Science, Kasetsart University, 50, Ngam Wong Wan Rd, Lad Yao, Chatuchak, Bangkok, 10900, Thailand.
    Background: Pasteurella multocida is a Gram-negative bacterium that causes economically significant infections of a broad range of animal species. Pneumonic and septicaemic pasteurellosis caused by this bacterium remain important problems in pigs, cattle, and water buffaloes in Thailand. The aim of this study was to characterise the virulence-associated gene profiles and to develop an OmpA molecular typing scheme for classifying 191 bovine and porcine isolates of P. Read More

    Genotyping and comparative pathology of Spirocerca in black-backed jackals (Canis mesomelas) in South Africa.
    BMC Vet Res 2017 Aug 16;13(1):245. Epub 2017 Aug 16.
    Section Pathology, Department of Paraclinical Sciences, Faculty of Veterinary Science, University of Pretoria, Private bag X04, Onderstepoort, 0110, South Africa.
    Background: The pathology of spirocercosis, a disease caused by the infestation of carnivores with the nematode Spirocerca lupi, has been extensively described in domestic dogs and coyotes. However, it has not been described in wild carnivores in South Africa. The aim of this study was to evaluate whether black-backed jackals are a host for Spirocerca species and to provide a detailed description of the associated pathology. Read More

    Quality assurance and best research practices for non-regulated veterinary clinical studies.
    BMC Vet Res 2017 Aug 16;13(1):242. Epub 2017 Aug 16.
    College of Veterinary Medicine, University of Minnesota, St. Paul, MN, USA.
    Veterinary clinical trials generate data that advance the transfer of knowledge from clinical research to clinical practice in human and veterinary settings. The translational success of non-regulated and regulated veterinary clinical studies is dependent upon the reliability and reproducibility of the data generated. Clinician-scientists that conduct veterinary clinical studies would benefit from a commitment to research quality assurance and best practices throughout all non-regulated and regulated research environments.
