Leishmaniasis is a disease caused by a single-celled parasite that infects dogs, cats, and certain rodents. Humans can also become infected. The parasite is transmitted by small, biting sand flies.

Leishmaniasis in Dogs
Es una enfermedad causada por un parásito unicelular que afecta a los mamíferos en muchas partes del mundo y que está extendida por todos los países de la cuenca del Mediterráneo. Hay que tener en cuenta que la enfermedad también puede afectar a las personas, pero no existe una transmisión directa del perro al hombre o viceversa. Se transmite por la picadura de un pequeño mosquito (Phlebotomus spp).

Liver fluke (Heterobilharzia americana) is a parasitic worm that affects dogs in the southern Atlantic and Gulf states and causes a disease called schistosomiasis. The fluke’s lifecycle is complex and involves a freshwater snail. Dogs can become infected by swimming or wading in water that has the larval stages of the fluke. The flukes cause granulomas (inflammatory nodules) to form in the liver, intestines, and other abdominal organs. Symptoms of gastrointestinal and liver disease may be present.
