Host-Genetic-Based Outcome Of Co-Infection By Pcv2b And Prrsv In Pigs, Christian W. Eaton, Hiep Vu, Arabella L. Hodges, Seth P. Harris, Stephen D. Kachman, Daniel C. Ciobanu

School of Veterinary and Biomedical Sciences: Faculty Publications

Replication of porcine circovirus type 2 (PCV2), an important worldwide swine pathogen, has been demonstrated to be influenced by host genotype. Specifically, a missense DNA polymorphism (SYNGR2 p.Arg63Cys) within the SYNGR2 gene was demonstrated to contribute to variation in PCV2b viral load and subsequent immune response following infection. PCV2 is known to induce immunosuppression leading to an increase in susceptibility to subsequent infections with other viral pathogens such as porcine reproductive and respiratory syndrome virus (PRRSV). In order to assess the role of SYNGR2 p.Arg63Cys in co-infections, pigs homozygous for the favorable SYNGR2 p.63Cys (N = 30) …

Turkish Journal of Veterinary & Animal Sciences

The present study aimed to analyse the gestation length (GL) variability in locally born purebred Holstein dams (n = 1047), in a private farm, under Saharan climate. The overall GL mean was 278.73 ± 6.67 days. A general linear model revealed that the GL was significantly affected by calf sex (p = 0.035) with a minor increase of 0.19% in males, dam parity (p = 0.016) and calving season (p < 0.0001) including the shortest lengths recorded in heifers and during heat stress period. Moreover, a negative regression (-1.96%) in recent years was recorded in GL by the influence (p = 0.01) of years of birth, breeding, and calving of cows. Our findings show that cows that were inseminated and gave birth during the cold season (temperature-humidity index, THI < 74) had 11.54 days longer (p = 0.048) gestation period compared to animals that were inseminated and gave birth during the hot season (THI > 84). Similarly, the association (p = 0.003) between dam parity and calf sex revealed that the GL of multiparous cows that gave birth to male calves was higher (3.07 days) …

More People, More Cats, More Parasites: Human Population Density And Temperature Variation Predict Prevalence Of Toxoplasma Gondii Oocyst Shedding In Free-Ranging Domestic And Wild Felids, Sophie Zhu, Elizabeth Vanwormer, Karen Shapiro

School of Veterinary and Biomedical Sciences: Faculty Publications

Toxoplasma gondii is a ubiquitous zoonotic parasite that can infect warm-blooded vertebrates, including humans. Felids, the definitive hosts, drive T. gondii infections by shedding the environmentally resistant stage of the parasite (oocysts) in their feces. Few studies characterize the role of climate and anthropogenic factors in oocyst shedding among free-ranging felids, which are responsible for the majority of environmental contamination. We determined how climate and anthropogenic factors influence oocyst shedding in free-ranging domestic cats and wild felids using generalized linear mixed models. T. gondii oocyst shedding data from 47 studies were systematically reviewed and compiled for domestic cats and six …
