immunologic progression of canine leishmaniosis following vertical transmission in united states dogs.canine leishmaniosis (canl) is caused by leishmania infantum, an obligate intracellular protozoan parasite, endemic in u.s. hunting dog populations. canl has been found in dogs in 28 states and two canadian provinces. previous studies by our group, (boggiatto et al., 2011), demonstrated that vertical transmission of leishmania was the predominant means of transmission within u.s. dogs. very little is known regarding how this alternative means of transmission, alters the long-term immunity and cl ...201626827836
first description of naturally acquired tritrichomonas foetus infection in a persian cattery in spain.tritrichomonas foetus has been identified as the causative agent of feline intestinal trichomonosis, characterized by clinical signs of chronic large bowel diarrhoea. this disease has been reported in cats from the usa, europe and australia. however, its epidemiology is still unclear. the aim of the present study was to describe t. foetus infection in a persian cattery in spain. t. foetus infection was sequentially diagnosed in 20 cats by direct faecal smear examined under the microscope, specif ...201121509446
vectorborne transmission of leishmania infantum from hounds, united states.leishmaniasis is a zoonotic disease caused by predominantly vectorborne leishmania spp. in the united states, canine visceral leishmaniasis is common among hounds, and l. infantum vertical transmission among hounds has been confirmed. we found that l. infantum from hounds remains infective in sandflies, underscoring the risk for human exposure by vectorborne transmission.026583260
the current status of zoonotic leishmaniases and approaches to disease control.leishmaniases are a complex of world-wide diseases with a range of clinical and epidemiological features caused by leishmania spp. of protozoan parasites. among 15 well-recognised leishmania species known to infect humans, 13 have zoonotic nature, which include agents of visceral, cutaneous and mucocutaneous forms of the disease in both the old and new worlds. currently, leishmaniases show a wider geographic distribution and increased global incidence of human disease than previously known. envi ...200516162348
immunologic indicators of clinical progression during canine leishmania infantum both dogs and humans leishmania infantum infection is more prevalent than disease, as infection often does not equate with clinical disease. previous studies additively indicate that advanced clinical visceral leishmaniasis is characterized by increased production of anti-leishmania antibodies, leishmania-specific lymphoproliferative unresponsiveness, and decreased production of gamma interferon (ifn-gamma) with a concomitant increase of interleukin-10 (il-10). in order to differentiate infec ...201020032217
