The H5N1 avian influenza virus is transmitted between mammals from contaminated cow's milk and reaches the mammary glands

The H5N1 avian influenza virus can be transmitted between mammals, according to a study published in Nature. The research team isolated the virus from the milk of an infected cow in New Mexico (USA) and found that it spreads in mice and ferrets, reaching the mammary glands of both animals. In addition, the virus was also transmitted from infected lactating mice to their offspring. The European Centre for Disease Prevention and Control (ECDC) has issued a press release on Monday recommending increased surveillance for these viruses.

Article examines how dogs can be 'sentinels' of human health

Dogs and other pets can be sentinels for human health, two US researchers argue in the journal Science. Because they share the same environment as their owners, dogs can help study, for example, the epidemiology of vector-borne pathogens, the effects of exposure to heavy metals and endocrine disruptors, and even the effects of social adversity. Improving canine data collection would help assess the health of people who cohabit with dogs, the authors argue.

Reactions: 38% of dog owners say they give cannabinoids to their dogs, according to Danish survey

In an anonymous online survey of dog owners in Denmark, 38% of respondents said they administered cannabinoid products - such as cannabidiol drops - to their pets without a prescription, even though their use is not legal in animals. Reasons given included pain, behavioural problems and allergies in their dogs. Some 2,000 people responded to the survey, the results of which are published in the journal PLoS ONE.

Reactions: study reveals menopause in female chimpanzees

The vast majority of mammals remain fertile until the end of their lives. Humans and some species of whales deviate from that norm and do go through menopause. Now, research published in Science reveals that menopause exists in female chimpanzees, too, and that it lasts for a fifth of their adult lifespan. To reach these conclusions, the research team observed 185 female chimpanzees between 1995 and 2016 in Uganda's Kibale National Park and measured hormone levels in urine samples from specimens of various ages.

Reaction: Zoonoses from domestic animals pose an underestimated but very real threat, review finds

A review examines the role of domestic and semi-domestic animals, such as cats, in the emergence of potential zoonoses due to their close contact with humans. The paper, published in the journal Science Translational Medicine, concludes that companion animal health risks will become increasingly problematic with climate change and rapid urbanisation.

Reactions: sales of antibiotics for animal use have fallen by almost 50 % in the last ten years

The EMA's annual European Surveillance of Veterinary Antimicrobial Consumption (ESVAC) report shows that sales of antibiotics for animal use have decreased by 47% between 2011 and 2021. In addition, sales of antibiotics considered "critically important" for use in humans have also decreased.
