Pet cats infect two people with TB

Two people in England have developed tuberculosis after contact with a domestic cat, Public Health England has announced.Pet cats infect two people with TBThe two human cases are linked to nine cases of Mycobacterium bovis infection in cats in Berkshire and Hampshire. Both people were responding to treatment, PHE said.

M. bovis is the bacterium that causes tuberculosis in cattle, known as bovine TB, and other species.

Transmission of M. bovis from infected animals to humans can occur by breathing in or ingesting bacteria shed by the animal or through contamination of unprotected cuts in the skin while handling infected animals or their carcasses.

The nine cases of M. bovis infection in cats in Berkshire and Hampshire were investigated by PHE and the Animal Health and Veterinary Laboratories Agency (AHVLA) during 2013.

Tuberculosis (TB) is an infectious disease caused by a germ which usually affects the lungs.

Symptoms can take several months to appear and include:
•Fever and night sweats
•Persistent cough
•Losing weight
•Blood in your phlegm or spit

Almost all forms of TB are treatable and curable, but delays in detection and treatment can be damaging.

TB caused by M. bovis is diagnosed in less than 40 people in the UK each year. The majority of these cases are in people over 65 years old.

Overall, human TB caused by M. bovis accounts for less than 1% of the 9,000 TB cases diagnosed in the UK every year.

Those working closely with livestock and/or regularly drinking unpasteurised (raw) milk have a greater risk of exposure.

Public Health England

Screening was offered to people who had had contact with the infected cats. Following further tests, a total of two cases of active TB were identified.

Molecular analysis showed that M. bovis taken from the infected cats matched the strain of TB found in the human cases, indicating that the bacterium was transmitted from an infected cat.

Two cases of latent TB were also identified, meaning they had been exposed to TB at some point, but they did not have the active disease.

PHE said it was not possible to confirm whether these were caused by M. bovis or something else.

No further cases of TB in cats have been reported in Berkshire or Hampshire since March 2013.
‘Uncommon in cats’

Dr Dilys Morgan, head of gastrointestinal, emerging and zoonotic diseases department at PHE, said: “It’s important to remember that this was a very unusual cluster of TB in domestic cats.

“M. bovis is still uncommon in cats – it mainly affects livestock animals. These are the first documented cases of cat-to-human transmission, and so although PHE has assessed the risk of people catching this infection from infected cats as being very low, we are recommending that household and close contacts of cats with confirmed M. bovis infection should be assessed and receive public health advice.”

Out of the nine cats infected, six died and three are currently undergoing treatment.
