International Journal of Environmental Research and Publi... Sonola VS, Misinzo G et. al.

Aug 28th, 2021 - We conducted this study to investigate the isolation frequency and phenotypic antibiotic resistance pattern of Staphylococcus aureus isolated from rodents, chickens, humans, and household soils. Specimens were plated onto mannitol salt agar (Oxoid, Basingstoke, UK) and incubated aerobically at 37 °C for 24 h. Presumptive colonies of S. aureus were subjected to Gram staining, as well as catalase...

Emerging Infectious Diseases; Holloway P, Gibson M et. al.

Aug 24th, 2021 - After the first detection of Middle East respiratory syndrome coronavirus (MERS-CoV) in camels in Jordan in 2013, we conducted 2 consecutive surveys in 2014-2015 and 2017-2018 investigating risk factors for MERS-CoV infection among camel populations in southern Jordan. Multivariate analysis to control for confounding demonstrated that borrowing of camels, particularly males, for breeding purpos...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8386811
Emerging Infectious Diseases; de Oliveira-Filho EF, Fischer C et. al.

Aug 24th, 2021 - Among 713 equids sampled in northeastern Brazil during 2013-2018, West Nile virus seroprevalence was 4.5% (95% CI 3.1%-6.3%). Mathematical modeling substantiated higher seroprevalence adjacent to an avian migratory route and in areas characterized by forest loss, implying increased risk for zoonotic infections in disturbed areas.

Emerging Infectious Diseases; Espunyes J, Cabezón O et. al.

Aug 24th, 2021 - We conducted a serosurvey for Crimean-Congo hemorrhagic fever virus antibodies in various wildlife species in Catalonia, northeastern Spain. We detected high seroprevalence in southern Catalonia, close to the Ebro Delta wetland, a key stopover for birds migrating from Africa. Our findings could indicate that competent virus vectors are present in the region.

Aug 22nd, 2021 - In this study, we report the serological, bacteriological and whole genome sequencing data of a 6 years study of Brucella abortus in Meghalaya, India. Investigation of 3060 sera samples indicated overall prevalence of 6.4% by Rose Bengal Plate Test and 10.7% by ELISA. Considerably higher prevalence was observed among milk samples (17.5%, n = 362) and in blood samples (37.7%, n = 262) by direct ...

Development of a new antimicrobial concept for boar semen preservation based on bacteri...
https://doi.org/10.1016/j.theriogenology.2021.08.004
Theriogenology Jakop U, Hensel B et. al.

Aug 21st, 2021 - The conventional storage temperature of 16-18 °C provides optimal conditions for the preservation of boar sperm quality, which are extremely cold sensitive cells. On the other hand, however, it requires the addition of antibiotics to inhibit bacterial growth. Rising numbers of antibiotic resistant bacteria call for alternatives to this conventional storing method. As potential alternative, thre...

Comparative Immunology, Microbiology and Infectious Disea... Boutellis A, Aissi M et. al.

Aug 21st, 2021 - Blastocystis sp. is one of the most common enteric parasites found in humans and many non-human hosts. It is an anaerobic protozoan that belongs to the group of Stramenopiles. Based on phylogenetic analysis of ribosomal DNA genes, at least 17 subtypes (ST1-ST17) are described. The aim of this study was to identify and characterize Blastocystis sp. in stool samples from various animal groups and...

https://doi.org/10.1016/j.theriogenology.2021.07.023
Theriogenology Ribas-Maynou J, Mateo-Otero Y et. al.

Aug 20th, 2021 - In situations where an excessive generation of reactive oxygen species overwhelms antioxidant capacity, a harmful effect on sperm function is exerted. Antioxidants are molecules capable of minimizing this detrimental effect, which is important in pig sperm due to the high content of polyunsaturated fatty acids in their plasma membrane. The present systematic review aims at evaluating whether su...

Theriogenology Ding R, Qiu Y et. al.

Aug 18th, 2021 - With continuous improvement of sow litter size, breeders are gradually paying more attention to the quality of litter traits that directly impact the production efficiency of pig companies, such as the rate of piglets born alive (RBA) and the rate of healthy births (RHB). The objectives of this study are to dissect the genetic basis of litter traits in pig and to identify valuable genes and gen...

https://doi.org/10.1016/j.theriogenology.2021.06.025
Theriogenology Gong S, Jiang L et. al.

Aug 17th, 2021 - Although it is known that stresses on females damage oocytes with increased production of stress hormones, whether corticotrophin-releasing hormone (CRH) or adrenocorticotropic hormone (ACTH) harm oocytes directly are largely unknown. We demonstrated that CRH exposure during in vitro maturation impaired competence of both pig and mouse cumulus-oocyte-complexes (COCs), and it impaired competence...

Theriogenology Mangiavacchi PM, Caldas-Bussiere MC et. al.

Aug 17th, 2021 - In vitro fertilization and somatic cell nuclear transfer are assisted reproduction technologies commonly used in humans and cattle, respectively. Despite advances in these technologies, molecular failures can occur, increasing the chance of the onset of imprinting disorders in the offspring. Large offspring syndrome/abnormal offspring syndrome (LOS/AOS) has been described in cattle and has feat...

https://doi.org/10.1016/j.theriogenology.2021.08.007
Theriogenology Jiang Y, He Y et. al.

Aug 17th, 2021 - Chlorpyrifos (CPF), as one of the most extensively applied organophosphorus pesticides (OPs) in agricultural and domestic settings, causes a potential threat to human and animal health. Various reproductive toxicities of CPF have been reported, however, little information is available on whether CPF exposure could exert toxic effects on mammalian oocytes. Herein, the effects of CPF on the meiot...

https://doi.org/10.1016/j.theriogenology.2021.07.021
Theriogenology Ganjiani V, Ahmadi N et. al.

Aug 17th, 2021 - Oxidative stress, caused by extreme accumulation of un-scavenged reactive oxygen species, plays an integral role in the Ischemia-Reperfusion (I/R) injury to the testicles following testicular torsion. The current research aimed to examine the protective effects of crocin as a natural antioxidant on testicular I/R injury in rats. Animals were divided randomly into five groups (seven each): (1) s...

https://doi.org/10.1016/j.theriogenology.2021.08.011
Theriogenology Dubon MAC, Pedrosa VB et. al.

Aug 16th, 2021 - The age at first calving has a great economic impact on the beef cattle system and calving at 24 months is an objective of selection for a more efficient herd. However, an age at first calving around 36 months has been observed for Nellore cattle in Brazil. Thus, a genome-wide association study (GWAS) was carried out with 8376 records of age at first calving and 3239 animals genotyped with the ...

Parasite (Paris, France); Li DL, Gong QL et. al.

Aug 11th, 2021 - Eimeria spp. cause the disease coccidiosis, which results in chronic wasting of livestock and can lead to the death of the animal. The disease, common worldwide, has caused huge economic losses to the cattle industry in particular. This is the first systematic review and meta-analysis of the prevalence of bovine Eimeria in China. Our search of five databases including PubMed, ScienceDirect, Chi...
