“Leishmania-infected dogs may present an infection risk to other dogs, even in the absence of natural vectors, as direct transmission between dogs is possible,” they add.

Transmission may occur from animal to sand fly to human. Humans can also transmit the parasite between each other through a blood transfusion or shared needles. In some parts of the world, transmission may also occur from human to sand fly to human.

Leishmaniasis is a parasitic disease that is found in parts of the tropics, subtropics, and southern Europe. It is classified as a neglected tropical disease (NTD). Leishmaniasis is caused by infection with Leishmania parasites, which are spread by the bite of phlebotomine sand flies.

Leishmaniasis is a treatable and curable disease, which requires an immunocompetent system because medicines will not get rid of the parasite from the body, thus the risk of relapse if immunosuppression occurs. All patients diagnosed as with visceral leishmaniasis require prompt and complete treatment.

Skin lesions may change in size, becoming smaller but often enlarge and do not heal. Sores may be moist and leak fluid (like pus) or may be dry and crust over, and are usually painless. Individuals may develop lesions that are limited to one area of the body and may slowly heal on their own over 6-18 months.

The only Food and Drug Administration (FDA)-approved medications for the treatment of leishmaniasis are intravenous liposomal amphotericin B (L-AmB) for VL and oral miltefosine for CL, ML, and VL caused by particular species.

The skin sores of cutaneous leishmaniasis usually heal on their own, even without treatment. But this can take months or even years, and the sores can leave ugly scars.

Visceral disease, the most devastating and fatal form of leishmaniasis, is classically known as kala-azar or the Indian name for “black fever/disease,” which is a reference to the characteristic darkening of the skin that is seen in patients with this condition.

Blood tests that detect antibody (an immune response) to the parasite can be helpful for cases of visceral leishmaniasis; tests to look for the parasite (or its DNA) itself usually also are done.

Leishmaniases are neglected diseases caused by infection with Leishmania parasites and there are currently no prophylactic vaccines.

According to other studies, vaccination cannot eradicate leishmaniasis. There is no perfect vaccine or suitable drug to eradicate leishmaniasis completely. So far, no vaccine or drug has been provided to induce long-term protection and ensure effective immunity against leishmaniasis.

Currently, there is no human vaccine for Lyme disease—even though more than two decades ago, people could get a safe and effective preventative shot similar to Fawn’s.

Some scientific studies indicate that Lyme disease vaccines for dogs may only last about six months, although many more studies are needed to determine if this is true.

Our commitment to leadership is vaccine development that provides comprehensive protection against Lyme disease. INDICATIONS: Shown to be effective for vaccination of healthy dogs 8 weeks of age or older against Borrelia burgdorferi. Duration of Immunity is at least 1 year.

Lyme disease is caused by infection with the bacterium Borrelia burgdorferi. Although most cases of Lyme disease can be cured with a 2- to 4-week course of oral antibiotics, patients can sometimes have symptoms of pain, fatigue, or difficulty thinking that last for more than 6 months after they finish treatment.

If treated, Lyme disease does not last for years. However, for some people, the after-effects of the disease can linger for months and sometimes even years.

Feb. 1, 2000 (Washington) — People afflicted with Lyme disease go on to lead normal lives, plagued by the same nettlesome but rarely serious problems that are reported by most people, according to the largest study on the long-term effects of the tick-borne illness.
