The Economic Burden of Chromosome Translocations and the Benefits of Enhanced Screening for Cattle Breeding.

Animals (Basel) 2022 Aug 5;12(15). Epub 2022 Aug 5.

School of Biosciences, University of Kent, Canterbury CT2 7NH, UK.

The cattle breeding industry, through both of its derivatives (dairy and beef), provides 81% of milk and 22% of meat required globally. If a breeding bull is sub-fertile, this impacts herd conception and birth rates, and it is generally accepted that having a proactive genetic screening programme can prevent further losses. Chromosome translocations are the leading genetic cause of infertility in livestock and, in cattle, this extends beyond the classical 1:29 to other Robertsonian translocations (RobTs) and to reciprocal translocations (RECTs).

Flukicidal effects of abietane diterpenoid derived analogues against the food borne pathogen Fasciola hepatica.

Vet Parasitol 2022 Jul 20;309:109766. Epub 2022 Jul 20.

Institute of Biological, Environmental and Rural Sciences (IBERS), Aberystwyth University, SY23 3DA Wales, UK. Electronic address:

Control of liver fluke infections remains a significant challenge in the livestock sector due to widespread distribution of drug resistant parasite populations. In particular, increasing prevalence and economic losses due to infection with Fasciola hepatica is a direct result of drug resistance to the gold standard flukicide, triclabendazole. Sustainable control of this significant zoonotic pathogen, therefore, urgently requires the identification of new anthelmintics. Read More

New Insights in the Interplay Between African Swine Fever Virus and Innate Immunity and Its Impact on Viral Pathogenicity.

Front Microbiol 2022 6;13:958307. Epub 2022 Jul 6.

UMR 1282 ISP, INRAE Centre Val de Loire, Nouzilly, France.

The continuous spread of African swine fever virus (ASFV) in Europe and Asia represents a major threat to livestock health, with billions of dollars of income losses and major perturbations of the global pig industry. One striking feature of African swine fever (ASF) is the existence of different forms of the disease, ranging from acute with mortality rates approaching 100% to chronic, with mild clinical manifestations. These differences in pathogenicity have been linked to genomic alterations present in attenuated ASFV strains (and absent in virulent ones) and differences in the immune response of infected animals.

Brucellosis is a neglected zoonosis and a public health problem in developing countries that also causes great economic losses in livestock. In Mexico it is endemic and Chiapas, a state in the south of the country, stands out for the presence of the disease in humans. Through the review of the state of the art it was found that factors such as the high production of cattle, the limited institutional strategies to control the disease in livestock, the lack of sanitary regulation of the genus Brucella in dairy and meat products and the location of the state of Chiapas on the border with Central America could be determining factors for the prevalence of human brucellosis in this region of Mexico.
