Can i catch leishmaniasis from my dog

The dog had been with his owners since he was a puppy, and showed none of the known symptoms of the bug. He was diagnosed with leichmaniosis, and vets suspect dog-to-dog transmission is the most likely explanation for him falling sick. Another dog in the household had been imported from Spain, and had to be put down six months earlier after developing severe leishmaniosis.

Writing in the BMJ, a team of vets said: "To the authors' knowledge, this is the first reported case of leishmaniosis in the UK in a dog without a history of travel to an endemic area. Since the first case, the authors warn another dog - a fully vaccinated English pointer - has also been diagnosed with the infection, in a different part of the UK.

However, 1 in 4 households in the UK has a dog, and infections can jump between the species. Diarrhoea in humans can occur for a multitude of reasons. Acute diarrhoea is often the result of a food toxicity, and a proportion of these cases are caused by ingesting food contaminated with bacteria or viruses. As any dog owner will testify, dogs frequently get diarrhoea too. Most of the time this is because dogs are often fond of eating rubbish in the park, but infections can cause diarrhoea as well.

The common bacteria that are able to infect humans and dogs include E. Theoretically, these bacteria can all be zoonotic. Humans are much more likely to become infected by these agents from an undercooked dinner as opposed to a pet dog, but good hygiene around dog poo is always a sensible idea.

A couple of diarrhoea-inducing viruses have also been suggested to be zoonotic pathogens. Rotavirus is a common cause of childhood diarrhoea, although the recent introduction of a rotavirus vaccine has considerably reduced the number of infected infants. Analysis of the sequences of human rotaviruses has shown that some are similar to canine rotavirus strains. There are very rare case reports of children being infected by suspect canine rotavirus strains, but the emphasis must be on 'very rare'.

Another recent paper raised the question about dogs and human norovirus. An owner was found to be infected with the same norovirus strain that was infecting their dog. It is yet to be established if norovirus is anything to worry about in dogs, but given that most human infections occur in locations where dogs are generally forbidden, e.

One of most common skin problems transmitted from dogs to humans is fleas. Dog fleas feed on dog blood, drop off and lay eggs nearby, then when these hatch they will feed on the nearest warm-blooded creature. Fleas cannot complete their life cycle on humans alone, but will certainly leave a series of insect bites behind if they come into contact with human skin.

Fleas are easily treatable with the correct products for dogs and their environment, and should never be a significant problem. Alongside fleas, mites are another zoonotic skin parasite that can cause disease in humans. Sarcoptes and Cheyletiella mites are generally uncommon in dogs, but worth considering if routine flea treatment isn't stopping your dog itching. Dermatophytosis or 'ringworm' is a fungal skin disease that can spread from dogs and other animals to humans.

Circular, scaly patches of skin with broken hairs characterize the disease, although some dogs can be asymptomatic carriers. It is always advisable to get any unusual skin lesions on your dog examined by a vet.

If you develop similar skin problems, it could be important to tell your own doctor about any contact with animals. A much rarer human skin disease that can be spread by dogs is leishmaniasis. Leishmania parasites are transmitted by sandflies, which feed on dogs and can then pass the parasite onto humans. Affected humans with the cutaneous form of disease develop skin nodules which may progress to ulcers. With the visceral form of disease, the spleen, liver and bone marrow is affected.

And there is always a possibility of a relapse in the future and the need to repeat the treatment. What are the early clinical signs of canine leishmaniasis? Weeping skin sores or ulcers are common on the head and legs. There is always some weight loss, which can be very severe, although appetite may remain good. Other occasional signs are nose bleeds and eye troubles.

Later, the claws may overgrow and become twisted. Kidney failure is a common sign, but this would not be obvious to the owner. How can the vet be sure my dog has leishmaniasis? Diagnosis can be made by direct detection of the parasite by microscopical examination of a small sample of bone marrow or a lymph gland, serological detection such as blood tests for antibodies or the demonstration of parasite DNA in circulating blood cells or a tiny piece of skin PCR.

Is a dog still infectious to sand flies during and after treatment? Can the disease be transmitted only by a bite of an infected sand fly, or can the infection be passed on, for example, by contact with blood or skin lesions? What is the danger to people or other dogs living close to an infected dog? This will greatly reduce the risk of dogs infecting sand flies and vice-versa. Whether you live in an endemic area or not, it is a good idea to make sure infected dogs are not in close contact with other dogs.

There are very rare reports of dog-to-dog transmission in places where there are no sand flies and there cannot be transmission by the bite of a vector. Direct dog-to-human transmission has never been reported, even among veterinarians who have handled hundreds of dogs with leishmaniasis.

Nevertheless, it is not a good idea to let babies or toddlers play with a leishmanial dog when it is obviously very sick. Load comments 0. Let us know if there is a problem with our content. Your message to the editors.
