Bovine-like coronaviruses in domestic and wild ruminants.

Anim Health Res Rev 2018 Dec;19(2):113-124

Department of Virology, Faculty of Veterinary Medicine,Cairo University,11221 Giza,Egypt.

Coronaviruses (CoVs) produce a wide spectrum of disease syndromes in different mammalian and avian host species. These viruses are well-recognized for their ability to change tissue tropism, to hurdle the interspecies barriers and to adapt ecological variations. It is predicted that the inherent genetic diversity of CoVs caused by accumulation of point mutations and high frequency of homologous recombination is the principal determinant of these competences.

What do we know about parasites of wildlife in high biodiversity areas with anthropogenic disturbance? The special case of Mexico.

Anim Health Res Rev 2018 Dec;19(2):155-161

Departamento de Sanidad Animal, Facultad de Veterinaria,Regional Campus of International Excellence "Campus Mare Nostrum", Universidad de Murcia,30100 Murcia,Spain.

The continual rise of anthropogenic disturbance of ecosystems has been associated with an increasing incidence of emerging diseases. The largest amount of data on emerging diseases relates to bacterial and viral pathogens, but there is a lack of parasite data, especially from wildlife. Monitoring wildlife parasitic diseases should be considered a priority, especially in high biodiversity regions with strong anthropogenic impacts, like Mexico, where the wildlife/livestock/human interface is associated with increased risk of disease transmission.

Plasmid-mediated colistin resistance in animals: current status and future directions.

Anim Health Res Rev 2017 Dec;18(2):136-152

Department of Animal Science,The University of Tennessee,2506 River Drive, Knoxville, TN 37996,USA.

Colistin, a peptide antibiotic belonging to the polymyxin family, is one of the last effective drugs for the treatment of multidrug resistant Gram-negative infections. Recent discovery of a novel mobile colistin resistance gene, mcr-1, from people and food animals has caused a significant public health concern and drawn worldwide attention. Extensive usage of colistin in food animals has been proposed as a major driving force for the emergence and transmission of mcr-1; thus, there is a worldwide trend to limit colistin usage in animal production.

The physiological role of the gastrointestinal microbiota has become an important subject of nutrition research in pigs in the past years, and the importance of intestinal microbial activity in the etiology of disease is doubtless. This review summarizes the recent knowledge related to the microbial ecology of protein fermentation and the appearance of protein-derived metabolites along the pig intestine. The amount of fermentable protein depends on factors such as dietary protein concentration, protein digestibility due to secondary or tertiary structure, the interaction with dietary compounds or anti-nutritional factors, and the secretion of endogenous proteins into the gut lumen.

Protocol for diversion of confirmed positive bulk raw milk tankers to calf ranches - A review of the Pharmacokinetics of tetracyclines and sulfonamides in veal calves.

Anim Health Res Rev 2016 12 18;17(2):127-136. Epub 2016 Aug 18.

Food Animal Residue Avoidance and Depletion Program (FARAD) and Institution of Computational Comparative Medicine, Kansas State University College of Veterinary Medicine,Kansas,USA.

The tetracyclines (TTC) and sulfonamides are among the most common residues found in bulk raw milk samples. Detection of drug residues in bulk milk (BM) tankers demonstrates that the product is not suitable for human consumption. Discarding BM with residue-contaminated milk is a waste of a valuable commodity, and a repurposing for consumption at calf ranches is a way to recapture some value. Read More

Where literature is scarce: observations and lessons learnt from four systematic reviews of zoonoses in African countries.

Anim Health Res Rev 2016 06;17(1):28-38

International Livestock Research Institute,Nairobi,Kenya.

The success of a systematic review depends on the availability, accessibility and quality of literature related to the review question. This paper presents the literature found in four systematic reviews conducted for a selection of zoonotic hazards in four livestock value chains in Africa, as well as setting out the challenges in conducting the reviews. The protocol was designed following international standards, and addressed four questions around prevalence, risk factors, control options and impact of various hazards and populations. Read More

What is the evidence that point sources of anthropogenic effluent increase antibiotic resistance in the environment? Protocol for a systematic review.

Anim Health Res Rev 2016 06;17(1):9-15

Department of Veterinary and Biomedical Sciences,University of Minnesota,1971 Commonwealth Avenue,St. Paul,MN 55108,USA.

Herein we describe a protocol for a systematic review of the evidence on whether point sources of anthropogenic effluent are associated with an increase in antibiotic resistance in the adjacent environment. The review question was based on the Population, Exposure, Comparator, Outcome, Study Design (PECOS) framework as follows: Is the prevalence or concentration of antibiotic resistant bacteria or resistance genes (O) in soil, water, air or free-living wildlife (P) higher in close proximity to, or downstream from, known or suspected sources of anthropogenic effluent (E) compared to areas more distant from or upstream from these sources (C)? A comprehensive search strategy was created to capture all relevant, published literature. Criteria for two stages of eligibility screening were developed to exclude publications that were not relevant to the question, and determine if the study used a design that permitted estimation of an association between a source and levels of resistance.

Diagnostic accuracy of refractometer and Brix refractometer to assess failure of passive transfer in calves: protocol for a systematic review and meta-analysis.

Anim Health Res Rev 2016 06;17(1):3-8

Department of Veterinary Medicine,Faculty of Sciences,Integrated Veterinary Research Unit,Research Institute for Life Sciences,Université de Namur,Rue de Bruxelles 61,5000 Namur,Belgium.

Calves are highly dependent of colostrum (and antibody) intake because they are born agammaglobulinemic. The transfer of passive immunity in calves can be assessed directly by dosing immunoglobulin G (IgG) or by refractometry or Brix refractometry. The latter are easier to perform routinely in the field. Read More

The pathogenesis of bornaviral diseases in mammals.

Anim Health Res Rev 2016 12 23;17(2):92-109. Epub 2016 May 23.

Department of Veterinary Pathobiology and the Schubot Exotic Bird Health Center,Texas A&M University,College of Veterinary Medicine and Biomedical Sciences,College Station,Texas 77843,USA.

Natural bornavirus infections and their resulting diseases are largely restricted to horses and sheep in Central Europe. The disease also occurs naturally in cats, and can be induced experimentally in laboratory rodents and numerous other mammals. Borna disease virus-1 (BoDV-1), the cause of most cases of mammalian Borna disease, is a negative-stranded RNA virus that replicates within the nucleus of target cells. Read More

Vaccination of calves against common respiratory viruses in the face of maternally derived antibodies(IFOMA).

Anim Health Res Rev 2016 12 4;17(2):79-84. Epub 2016 Apr 4.

Department of Pathobiology,College of Veterinary Medicine, Auburn University,Auburn AL 36849,USA.

Vaccination of calves in the face of maternal antibodies (IFOMA) often does not result in seroconversion as maternally derived immunity interferes with the activation of adequate antibody responses to vaccination; however, it can prime T and B cell memory responses that protect calves against clinical disease when maternal immunity has decayed. The activation of B and T cell memory responses in calves vaccinated IFOMA varies and is affected by several factors, including age, level of maternal immunity, type of vaccine, and route of administration. These factors influence the adequate priming of humoral and cell mediated immune responses and the outcome of vaccination. Read More

Passive immunization with hyperimmune egg-yolk IgY as prophylaxis and therapy for poultry diseases--A review.

Anim Health Res Rev 2015 Dec 16;16(2):163-76. Epub 2015 Nov 16.

Animal Biosciences and Biotechnology Laboratory,Beltsville Agricultural Research Center,Agricultural Research Service,USDA,Beltsville,MD 20705,USA.

Passive immunization with pathogen-specific egg yolk antibodies (IgY) is emerging as a potential alternative to antibiotics for the treatment and prevention of various human and animal diseases. Laying hens are an excellent source of high-quality polyclonal antibodies, which can be collected noninvasively from egg yolks. The use of IgY offers several advantages in that it is environmentally friendly, nontoxic, and reduces the numbers of animals required for antibody production. Read More
