First transmission of NDM bacteria between dog and human
This study is presumed to be the first in which researchers have shown the transmission of NDM-bacteria between dogs and humans.
Researchers isolate highly resistant strain from family dogs and owner

Researchers in Finland have reported the first-ever transmission of New Delhi metallo-beta-lactamase (NDM) bacteria between a dog and a human.

In 2015, NDM bacteria were identified in two Finnish dogs. Now, writing in the journal Eurosurveillance, Dr Thomas Grönthal and his team reveal that the owner of the dogs also carried the bacteria.

Dr Grönthal explains: “We were able, through the analysis of the genome of the bacteria, to conclude that the bacterial isolates from the dogs and humans were identical, which means that they were transmitted between dogs and humans.”

The study was a collaboration between the University of Helskini, the National Institute of Health and Welfare, and the Finish Food Safety Authority.

Researchers isolated a highly resistant NDM-5 producing bacterial strain from two family dogs and one of the family members. Both dogs and two members of the family also carried a multidrug-resistant ESBL bacterium.

The ESBL and the NDM bacterial strains researchers isolated from the humans and dogs were identical. However, the humans did not show any symptoms and the researchers were unable to identify the source of the NDM bacteria.

“We could not show with certainty in which direction the bacteria had transmitted, explains lead researcher Merja Rantala. “However, especially the NDM-bacteria probably moved from human to dog as these bacteria have not previously been identified in animals in Finland.”

“The use of carbapenem antibiotics in animals is prohibited in Finland, but the dogs had received numerous other antibiotics. This gave the NDM-bacteria a competitive edge and enabled them to persist in the dogs.”

This study is presumed to be the first in which researchers have shown the transmission of NDM-bacteria between dogs and humans. However, car­bapenemase-pro­du­cing bac­teria are becoming more common in animals.

Researchers recommend that laboratories investigating animal specimens should monitor the susceptibility of bacteria to carbapenems and extended-spectrum cephalosporins.

Vets save premature penguin chick

News Story 1
 Vets have saved a tiny Humboldt penguin chick after her egg was accidentally broken by her parents. Keepers at ZSL London Zoo were shocked to find the chick, named Rainbow, still alive and rushed her straight to the Zoo’s on-site veterinary clinic.

It was a little way to go until the chick should have hatched, so the process was touch and go. Vets removed bits of shell from around the chick with tweezers until she could be lifted out and placed in a makeshift nest.

Rainbow is now in a custom-built incubation room where she spends her days cuddled up to a toy penguin. Keepers will hand-fed Rainbow for the next 10 weeks until she is healthy enough to move to the penguin nursery.

BVA infographic to help shoppers understand farm assurance schemes

An infographic to help members of the public understand farm assurance schemes has been produced by the BVA. The infographic outlines BVA’s priorities for animal welfare and shows whether or not the schemes address these priorities in their standards.

BVA president John Fishwick said: “The infographic is not intended to be a league table but to allow people to understand what aspects of animal health and welfare are addressed by assurance schemes so that they can decide which scheme best aligns with their own individual preferences and priorities."
