Characterization of Mycobacterium bovis in Mozambique

The most extensive study to date of the genetic diversity of Mycobacterium bovis isolates from Mozambique is reported in PLOS Neglected Tropical Diseases. Bovine tuberculosis (BTB) is of global concern for multiple reasons – the economic impact on animal production, the potential spread to wildlife, and the risk of transmission to humans. While BTB is […]

One Health study of tick-borne diseases in Mongolia

To better understand the epidemiology of tick-borne disease in Mongolia, a comprehensive seroprevalence study was conducted investigating exposure to Anaplasma spp. and spotted fever group (SFG) Rickettsia spp. in nomadic herders and their livestock across three provinces from 2014 to 2015. Dr. Michael von Fricken spent a year living in Ulaanbataar as a postdoc with […]

Roadmap to combat bovine and zoonotic tuberculosis

The Roadmap for Zoonotic Tuberculosis was launched at the 48th Union World Conference on Lung Health, which took place in Guadalajara, Mexico, 11-14 October 2017. Four partners in health, the World Health Organization (WHO), the World Organisation for Animal Health (OIE), the Food and Agriculture Organization of the United Nations (FAO) and the International Union […]

Modified virus shows promise as an ASF vaccine

Researchers have found that deleting a gene of African swine fever virus (ASFV) reduces its ability to cause infection and protects against a strain of the virus that causes severe disease. In the study, published in the Journal of Virology, scientists at The Pirbright Institute deleted an ASFV gene that codes for a protein (DP148R) thought […]

Study reveals dynamic state of bTB epidemiology in Cameroon

Dr Adrian Muwonge and Professor Mark Bronsvoort from The Roslin Institute and colleagues from the UK, Cameroon, Nigeria and Chad conducted the largest molecular epidemiological study of bovine tuberculosis (bTB) in a sub-Saharan African country to understand the incidence and diversity of the disease throughout Cameroon. Their findings are published in Scientific Reports. They collected […]

Study explores how African swine fever spreads in backyard production systems

Researchers at the University of California, Davis’ Center for Animal Disease Modeling and Surveillance (CADMS) and FAO examined the pig trade structure of four pig-rearing regions of Georgia, a country with predominant backyard production systems, whose pig production was recently devastated as a consequence of African swine fever (ASF) epidemics. Their findings are reported in […]

Foot and mouth disease: impact of preclinical diagnosis on farm-to-farm transmission

Preclinical detection of Foot-and-mouth disease virus (FMDV) during outbreaks has the potential to allow earlier culling of infected herds and thereby reduce transmission and aid the control of epidemics. During an outbreak of foot and mouth disease, current control and eradication methods rely on rapid clinical detection and the removal of infected herds. In a […]

Bats are the major reservoir of coronaviruses worldwide

Results of a five-year study in 20 countries on three continents have found that bats harbour a large diversity of coronaviruses (CoV). Findings from the study – led by scientists in the USAID-funded PREDICT project at the Center for Infection and Immunity (CII) at Columbia University’s Mailman School of Public Health and the University of […]

Pandemic potential of H9N2 avian influenza viruses studied

Researchers have identified the molecular mechanisms that enable H9N2 viruses – the most common type of avian influenza virus – to infect humans, helping improve risk assessments for its potential to cause pandemic. Although H9N2 viruses are considered less pathogenic than some types of avian influenza virus, they still cause significant losses for the poultry […]

Novel antibiotic resistance gene in milk

Researchers at the University of Bern have identified a new antibiotic resistance gene in Macrococcus caseolyticus strains from dairy cows. This gene confers resistance to all beta-lactam antibiotics including the last generation of cephalosporins used against methicillin-resistant Staphylococcus aureus (MRSA). A transfer to S. aureus (which is possible according to the researchers) would jeopardize the […]
