A team of researchers from 3 faculties at the University of Bern has now discovered how the bacterium causes fatal intestinal bleeding. They have thus made a breakthrough in veterinary research. Promising prospects ...Read more -
Cracking the genetic code for complex traits in cattle
Global genomic study accurately maps height in cattle, humans and dogs A massive global study involving 58,000 cattle has pinpointed the genes that influence the complex genetic trait of height in cattle, opening the door for researchers to use the same approach to map high-value traits including...Read more -
Conflict between farmers and livestock predators
A new Journal of Wildlife Management study conducted in South Africa has found that black-backed jackals, a similar species to coyotes and dingoes, prefer to eat livestock rather than similar-sized wild prey, which has important consequences for livestock husbandry and the management of predators...Read more -
Probing the In Vitro Cytotoxicity of the Veterinary Drug Oxytetracycline
Abstract The study investigated the effect of oxytetracycline (OTC) on the anti-oxidative defense system, the structure (hemolysis rate and morphology) and function (ATP enzyme activity) of human red blood cells (hRBCs) to investigate the possible toxic mechanism of OTC to hRBCs. The experimenta...Read more -
Cattle-killer Two parasites are better than one
When calves are infected by two parasite species at the same time, one parasite renders the other far less deadly, according to a new study published in the current journal of Science Advances. The international team of scientists has quantified, for the first time, how co-infection significantly...Read more -
Cattle, sheep and goats may transmit leptospirosis to humans in Tanzania
Leptospirosis, which affects more than one million people worldwide each year, is known to be transmitted to humans from a wide range of animals. Now, researchers reporting in PLOS Neglected Tropical Diseases have discovered that more than 7 percent of the cattle and 1 percent of sheep and goats ...Read more -
Cattle Unraveling the immunopathogenesis of Johne’s disease
A research team has unraveled the immunopathogenesis of Johne’s disease, a chronic bovine disease that has caused endemics in Japan and many other countries, placing financial burdens on cattle farmers. Researchers of Hokkaido University, the National Agriculture and Food Research Organizat...Read more -
Cattle may spread leptospirosis in Africa, study suggests
The bacterial infection leptospirosis is increasingly recognized as an important cause of fever in Africa. Now, researchers reporting in PLOS Neglected Tropical Diseases have analyzed the major risk factors for contracting leptospirosis and discovered that rice and cattle farming are associated w...Read more -
Wild animals’ immune systems decline with age, sheep study finds
It is well established that weakened immune systems in old age affect people’s health and fitness, but a study suggests that it is also an issue for wild animals. Researchers studying wild Soay sheep on the remote St Kilda archipelago have revealed that the animals’ immune responses t...Read more -
Toxin promotes cattle-to-cattle transmission of deadly Escherichia coli strains
Shiga toxin subtype 2a (Stx2a) may play a key role in promoting the colonization and transmission of life-threatening Escherichia coli strains in cattle, according to a study published October 3 in the open-access journal PLOS Pathogens by Tom McNeilly of the Moredun Research Institute, David Gal...Read more -
Respiratory diseases linked with high blood pressure in lungs
Pulmonary hypertension is a type of high blood pressure that affects the lungs of both animals and people. When tiny vessels in the lungs become narrowed or blocked, it becomes harder for blood to flow through and can cause the heart to weaken or fail. Now, researchers at the University of Missou...Read more -
Potential for reduced methane from cows
An international team of scientists has shown it is possible to breed cattle to reduce their methane emissions. Published in the journal Science Advances, the researchers showed that the genetics of an individual cow strongly influenced the make-up of the microorganisms in its rumen (the first st...Read more -
Poisonous grasses and livestock
Stories of mass poisoning incidents of livestock due to toxic grasses made headlines especially overseas. Animal ecologists have studied whether this hazard is also lurking on German pastures. “Dangerous Pastures: Deadly Grass Puts Horses at Risk” — Such dire warnings on the we...Read more -
Native bighorn sheep herds retain migratory diversity
On the surface, bighorn sheep migration is like that of many other large mammals, moving to higher elevations as snow melts in the springtime then returning to lower ground to forage as winter sets in. But a study published this month by Montana State University researchers has delved deeper, fin...Read more -
New vaccine will stop the spread of bovine TB
cientists at the University of Surrey have developed a novel vaccine and complementary skin test to protect cattle against bovine tuberculosis (bovine TB). Publishing their findings in the journal Scientific Reports, researchers reveal they have for the first time created a vaccine that is compat...Read more -
New insight into bacterial infections found in the noses of healthy cattle
New research led by academics at the University of Bristol Veterinary and Medical Schools used the ‘One Health’ approach to study three bacterial species in the noses of young cattle and found the carriage of the bacteria was surprisingly different. The findings which combined ideas a...Read more -
Immune response against Toxocara roundworms helps explain disease
Neurotoxocarosis (NT) occurs in humans when larvae of the Toxocara roundworm migrate into the central nervous system. That infection is accompanied by a complex molecular signaling cascade, including changes to anti-inflammatory lipid molecules, researchers now report in PLOS Neglected Tropical D...Read more -
Horse nutrition Prebiotics may do more harm than good
Prebiotics are only able to help stabilise the intestinal flora of horses to a limited degree. Before they can reach the intestines, commercially available supplements partially break down in the animals’ stomachs, which can lead to inflammation of the stomach lining. This was discovered by...Read more -
Sero-prevalence and community awareness on the risks associated with Livestock and Human brucellosis in selected districts of Fafan Zone of Ethiopian-Somali National Regional State
Abstract A cross-sectional study was conducted to estimate the sero-prevalence, potential risk factors for transmission and spread of brucellosis in livestock and human in Jigjiga and Gursum Woredas of Fafan Zone in Ethiopian-Somali. Two Kebeles were purposively selected from each Worada based o...Read more -
Changing climate may affect animal-to-human disease transfer
Climate change could affect occurrences of diseases like bird-flu and Ebola, with environmental factors playing a larger role than previously understood in animal-to-human disease transfer. Researchers from The University of Queensland and Swansea University have been looking at how different env...Read more -
Mechanism of a protein upon infection of the ‘Fasciola hepatica’
Fasciola hepatica is a parasite that causes on average 3.2 million in losses in the agricultural sector every year worldwide. It is a two-centimeter-long worm at adult size that mainly affects ruminants by means of water or raw vegetables that act as vehicles of infection. Moveover, in developing...Read more -
Buying and selling cattle can link individual farms to thousands of others per purchase
Understanding the complex networks of “contact chains” between British farms, could help identify potential routes for spread of infections and improve disease control strategies for the cattle industry. A pioneering new study, led by veterinary researcher Helen Fielding from the Univ...Read more -
Researchers control cattle microbiomes to reduce methane and greenhouse gases
Ben-Gurion University of the Negev (BGU) researchers have learned to control the microbiome of cattle for the first time which could inhibit their methane production, and therefore reduce a major source of greenhouse gasses. The findings from Prof. Itzhak Mizrahi’s findings were published r...Read more -
New experimental vaccine for African swine fever virus shows promise
Government and academic investigators have developed a vaccine against African swine fever that appears to be far more effective than previously developed vaccines.
