Abstract
Arthropod-borne infections are dependent on environmental conditions, and several combinations of natural and human-related variables play an important role in vector populations as well as the life cycle of agents carried by the arthropods. The top 5 canine arthropod-transmitted agents, Dirofilaria immitis, Leishmania spp., Ehrlichia canis, Anaplasma phagocytophilum, and Borrelia burgdorferi infect unprotected animals without propensity. The purpose of this study was to determine the prevalence of these parasite species in three different landscape settings (sandbanks, plains and mountains) along a 60-km line. During a 6-month period, blood samples were collected from dogs (>12months old) living in the different settings. Prevalence of D. immitis was determined by modified Knott test and ELISA. Prevalence of E. canis, A. phagocytophilum, and B. burgdorferi was determined by ELISA, and Leishmania spp. by ELISA, indirect immunofluorescence, and immunocromatographic assays. D. immitis was most prevalent in the sandbank (68.9%) as well as Leishmania spp. (34.5%), and tick-transmitted agents, A. phagocytophilum and E. canis in the plains (61.7%). B. burgdorferi was not detected. Depending on the resources for arthropods present in regions, dogs are likely to be exposed to different arthropod-borne parasites and should receive preventives tailored to the risk of infection in the region in which the dog resides.

Abstract
Since the description of Lutzomyia longipalpis by Lutz and Neiva
more than 100 years ago, much has been written in the scientific literature about
this phlebotomine species. Soares and Turco (2003) and Lainson and Rangel (2005) have
written extensive reviews focused on vector-host-parasite interactions and American
visceral leishmaniasis ecology. However, during the last two decades, the success of
Lu. longipalpis in colonising urban environments and its
simultaneous geographical spreading have led to new theoretical and operational
questions. Therefore, this review updates the general information about this species
and notes the more challenging topics regarding the new scenario of
urbanisation-spreading and its control in America. Here, we summarise the literature
on these issues and the remaining unsolved questions, which pose recommendations for
operational research.

First case of autochthonous human visceral leishmaniasis in the urban center of Rio de Janeiro: case report. Rev Inst Med Trop Sao Paulo 2014; 56:81-4. [PMID: 24553614 PMCID: PMC4085831 DOI: 10.1590/s0036-46652014000100013] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2013] [Accepted: 05/23/2013] [Indexed: 11/22/2022] Open
Abstract
Visceral leishmaniasis is an anthropozoonosis that is caused by protozoa
of the genus Leishmania, especially Leishmania
(Leishmania) infantum, and is transmitted to
humans by the bite of sandflies of the genus Lutzomyia, such as
Lutzomyia longipalpis. There are many reservoirs, including
Canis familiaris. It is a chronic infectious disease with
systemic involvement that is characterized by three phases: the initial period, the
state period and the final period. The main symptoms are fever, malnutrition,
hepatosplenomegaly, and pancytopenia. This article reports a case of a patient
diagnosed with visceral leishmaniasis in the final period following autochthonous
transmission in the urban area of Rio de Janeiro. The case reported here is
considered by the Municipal Civil Defense and Health Surveillance of Rio de Janeiro
to be the first instance of autochthonous visceral leishmaniasis in humans in the
urban area of this city. The patient was discharged and is undergoing a follow-up at
the outpatient clinic, demonstrating clinical improvement.
