The pathogenesis of bovine respiratory disease (BRD) is determined by a complex interaction of environmental, infectious, and host factors. Environment trends could impact feedlot cattle by increasing their level of stress. The polymicrobial nature of BRD produces synergies between infectious agents that can alter pathogenesis. However, the nature of the host response to these environmental and infectious challenges largely determines the characteristics of the progression and outcome of BRD.

Virus Genes | Year: 2016

Parvoviruses are a diverse group of viruses containing some of the smallest known species that are capable of infecting a wide range of animals. Metagenomic sequencing of pooled rectal swabs from adult pigs identified a 4103-bp contig consisting of two major open reading frames encoding proteins of 672 and 469 amino acids (aa) in length. BLASTP analysis of the 672-aa protein found 42.4 % identity to fruit bat (Eidolon helvum) parvovirus 2 (EhPV2) and 37.9 % to turkey parvovirus (TuPV) TP1-2012/HUN NS1 proteins. The 469-aa protein had no significant similarity to known proteins. Genetic and phylogenetic analyses suggest that PPV7, EhPV2, and TuPV represent a novel genus in the family Parvoviridae. Quantitative PCR screening of 182 porcine diagnostic samples found a total of 16 positives (8.6 %). Together, these data suggest that PPV7 is a highly divergent novel parvovirus prevalent within the US swine. © 2016 Springer Science+Business Media New York Source

Veterinary Immunology and Immunopathology | Year: 2014

Severe combined immunodeficiency (SCID) is the result of a set of inherited genetic defects which render components of the immune response nonfunctional. In Arabian horses, Jack Russell terriers, and mice, the disorder is a consequence of the absence of T and B lymphocytes, while natural killer (NK) cell and other leukocyte populations remain intact. Preliminary analysis of a naturally acquired form of inherited SCID in a line of pigs showed several defects in the architecture and composition of secondary lymphoid organs. In this study, a quantitative assessment of lymphocyte populations in affected and normal littermates showed depleted T or B lymphocyte populations in affected pigs; however, NK cells and neutrophils were present in numbers comparable to unaffected littermates. The results indicate that the immune defect in pigs shares the same features as other SCID-affected species. © 2014 Elsevier B.V. Source
