Biopurification of dairy farm wastewater through hybrid constructed wetland system: Groundwater quality and health implications.

Environ Res 2021 Jun 8:111426. Epub 2021 Jun 8.

Discipline of Earth Sciences, Indian Institute of Technology Gandhinagar, Gujarat, 382355, India. Electronic address:

Groundwater is under heavily threat owing to enormous infilteration of dairy farm originated wastewater into it. The anoxic environment in the groundwater due to mixing of organic rich wastewater can produce significant alterations in the groundwater quality. It is therefore necessary to treat such wastewaters before discharging to surrounding areas. Read More

SARS-CoV-2 in animals: potential for unknown reservoir hosts and public health implications.

Vet Q 2021 Dec;41(1):181-201

Faculty of Environmental Sciences, Department of Agriculture, King Abdulaziz University, Jeddah, Saudi Arabia.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, previously 2019-nCoV) is suspected of having originated in 2019 in China from a coronavirus infected bat of the genus . Following the initial emergence, possibly facilitated by a mammalian bridge host, SARS-CoV-2 is currently transmitted across the globe via efficient human-to-human transmission. Results obtained from experimental studies indicate that animal species such as cats, ferrets, raccoon dogs, cynomolgus macaques, rhesus macaques, white-tailed deer, rabbits, Egyptian fruit bats, and Syrian hamsters are susceptible to SARS-CoV-2 infection, and that cat-to-cat and ferret-to-ferret transmission can take place via contact and air.

Cocktails of pesticide residues in conventional and organic farming systems in Europe - Legacy of the past and turning point for the future.

Environ Pollut 2021 Jun 8;278:116827. Epub 2021 Mar 8.

Soil Physics and Land Management Group, Wageningen University & Research, Wageningen, the Netherlands.

Considering that pesticides have been used in Europe for over 70 years, a system for monitoring pesticide residues in EU soils and their effects on soil health is long overdue. In an attempt to address this problem, we tested 340 EU agricultural topsoil samples for multiple pesticide residues. These samples originated from 4 representative EU case study sites (CSS), which covered 3 countries and four of the main EU crops: vegetable and orange production in Spain (S-V and S-O, respectively), grape production in Portugal (P-G), and potato production in the Netherlands (N-P).

Arch Virol 2021 Apr 11;166(4):1093-1102. Epub 2021 Feb 11.

Animal Virology Laboratory, School of Life Sciences, College of Natural Sciences, BK21 FOUR KNU Creative BioResearch Group, Kyungpook National University, Daegu, 41566, Republic of Korea.

Porcine circovirus type 2 (PCV2) is the most ubiquitous viral pathogen of pigs and has persistently affected the global swine industry. Since first being identified in South Korea in 1999, the virus has undergone considerable genetic change and genotype shifts during the past two decades. These events have contributed to the coexistence of genotypes PCV2a, PCV2b, and PCV2d in Korean pig populations, which may promote viral recombination. Read More

Association of wild-type PRRSV detection patterns with mortality of MLV-vaccinated growing pig groups.

Prev Vet Med 2021 Apr 27;189:105270. Epub 2021 Jan 27.

Veterinary Diagnostic and Production Animal Medicine Department, Iowa State University College of Veterinary Medicine, Ames, IA, United States. Electronic address:

PRRS is a viral disease characterized by increasing reproduction losses in breeding herds and worsening performance of growing pigs, which leads to a considerable economic impact. A better understanding of the differences in the infection patterns of the virus in growing pig batches would help to develop cost-effective surveillance methods and disease control and elimination programs. Therefore, field studies documenting growing pig productivity according to the patterns of wild-type-PRRSV (wt-PRRSV) detection in the field are needed. Read More

Use of Network Analysis and Spread Models to Target Control Actions for Bovine Tuberculosis in a State from Brazil.

Microorganisms 2021 Jan 22;9(2). Epub 2021 Jan 22.

VISAVET Health Surveillance Centre, Universidad Complutense de Madrid, 28040 Madrid, Spain.

Livestock movements create complex dynamic interactions among premises that can be represented, interpreted, and used for epidemiological purposes. These movements are a very important part of the production chain but may also contribute to the spread of infectious diseases through the transfer of infected animals over large distances. Social network analysis (SNA) can be used to characterize cattle trade patterns and to identify highly connected premises that may act as hubs in the movement network, which could be subjected to targeted control measures in order to reduce the transmission of communicable diseases such as bovine tuberculosis (TB).

National Veterinary Research Institute, Vom, Nigeria.

Among recurrent sanitary emergencies able to spread rapidly worldwide, avian influenza is one of the main constraints for animal health and food security. In West Africa, Nigeria has been experiencing repeated outbreaks of different strains of avian influenza virus (AIV) since 2006 and is also recognized as a hot spot in the region for the introduction of emerging strains by migratory wild birds. Here, we generated complete genomes of 20 highly pathogenic avian influenza (HPAI) H5N8 viruses collected during active surveillance in Nigerian live bird markets (LBM) and from outbreaks reported in the country between 2016 and 2019.

Assessing genomic diversity and signatures of selection in Jiaxian Red cattle using whole-genome sequencing data.

BMC Genomics 2021 Jan 9;22(1):43. Epub 2021 Jan 9.

Key Laboratory of Animal Genetics, Breeding and Reproduction of Shaanxi Province, College of Animal Science and Technology, Northwest A&F University, No. 22 Xinong Road, Yangling, 712100, Shaanxi, China.

Background: Native cattle breeds are an important source of genetic variation because they might carry alleles that enable them to adapt to local environment and tough feeding conditions. Jiaxian Red, a Chinese native cattle breed, is reported to have originated from crossbreeding between taurine and indicine cattle; their history as a draft and meat animal dates back at least 30 years. Using whole-genome sequencing (WGS) data of 30 animals from the core breeding farm, we investigated the genetic diversity, population structure and genomic regions under selection of Jiaxian Red cattle.

Avian Disease Division, Animal and Plant Quarantine Agency, Gimcheon-si, Republic of Korea.

Infectious bursal disease (IBD) is one of the most important immunosuppressive diseases of young chickens, causing considerable economic losses to the poultry industry. More than 30 years ago, an antigenic variant (av) pathotype of the IBD virus (IBDV) was reported to originate in, and subsequently spread among, poultry farms in the USA. Recently, a novel avIBDV lineage was identified in China and was shown to exhibit clear differences in its pathogenicity as well as molecular characteristics compared with the previously isolated variant strains.
