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.

Amur leopard cubs caught on camera

News Story 1
 A pair of Amur leopards have been captured on camera for the first time since their birth. The Royal Zoological Society of Scotland announced the birth in July, but with human presence being kept to a minimum, it was not known how many cubs had been born.

Motion sensitive cameras have now revealed that two cubs emerged from the den - at least one of which may be released into the wild in Russia within the next two or three years. The Amur leopard habitat is not open to the public, to help ensure the cubs retain their wild instincts and behaviour. Image © RZSS

New canine and feline dentistry manual announced

A new canine and feline dentistry and oral surgery manual has been published by the BSAVA. Announcing the news on its website, the BSAVA said this latest edition contains new step-by-step operative techniques, together with full-colour illustrations and photographs.

‘This is a timely publication; veterinary dentistry is a field that continues to grow in importance for the general veterinary practitioner,’ the BSAVA said. ‘The manual has been fully revised and updated to include the most relevant, evidence-based techniques.’

The BSAVA Manual of Canine and Feline Dentistry and Oral Surgery, 4th edition is available to purchase from www.bsava.com/shop
