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.

Huge spike in ‘designer’ dogs going into rescue

News Story 1
 The RSPCA has reported a huge spike in the number of ‘designer’ dogs arriving into its care.

Figures published by the charity show there has been a 517 per cent increase in the number of French bulldogs arriving into its kennels. During that time, the charity has also seen an increase in dachshunds, chihuahuas, and crossbreeds.

RSPCA dog welfare expert Lisa Hens said: “We know that the breeds of dog coming into our care often reflect the trends in dog ownership in the wider world and, at the moment, it doesn’t get more trendy than ‘designer’ dogs like French bulldogs and Dachshunds."

AHDB Pork calls for stepped-up biosecurity

Pig farmers are being urged to step up biosecurity to reduce the risk of swine dysentery in their herds.

According to Farmers Weekly, AHDB Pork have confirmed cases in the north and east of the UK and is calling on producers to focus on hygiene to protect their animals.

Members of the AHDB Pork Significant diseases charter are reported to have been informed of the outbreaks.
