| epidemiological studies on american leishmaniasis in ceará state, brazil. molecular characterization of the leishmania isolates. | two methods of molecular characterization, using monoclonal antibodies and enzyme electrophoresis, were employed in the identification of 36 stocks of leishmania isolated from human and canine cases of american visceral (avl) and cutaneous (acl) leishmaniases in the northern part of ceará state, brazil. molecular homogeneous strains of leishmania donovani (chagasi) isolated from both human and canine hosts were detected in 14 municipalities. two more parasite species, l. braziliensis braziliensi ... | 1988 | 3256276 |
| identification and distribution of new world leishmania species characterized by serodeme analysis using monoclonal antibodies. | five hundred thirty stocks of leishmania isolated from human and domestic and wild reservoir hosts, representing a wide geographic distribution of endemic foci of american cutaneous (acl) and visceral leishmaniases (avl) were characterized and identified at species and/or subspecies levels based on their reactivity to a cross-panel of specific monoclonal antibodies using a radioimmune binding assay. this study confirms and extends our preliminary results on the high specificity of some of these ... | 1987 | 3826486 |

| bubonic leishmaniasis: a common manifestation of leishmania (viannia) braziliensis infection in ceara, brazil. | enlarged regional lymph nodes have been reported to accompany the cutaneous lesions of leishmania (viannia) braziliensis (= l. braziliensis). a survey in ceara state, brazil indicated that 77% of persons (456 of 595) with parasitologically confirmed cutaneous leishmaniasis reported lymphadenopathy in addition to skin lesions. a group of 169 persons with recently diagnosed leishmaniasis and lymph nodes measuring > or = 2 cm in diameter (mean = 3.6 cm, maximum = 10.5 cm) underwent detailed clinica ... | 1995 | 7485690 |
| cutaneous leishmaniasis in ceara state in northeastern brazil: incrimination of lutzomyia whitmani (diptera: psychodidae) as a vector of leishmania braziliensis in baturite municipality. | baturite is an important endemic zone of american cutaneous leishmaniasis in the state of ceara, where an entomologic survey has been carried out to obtain information about transmission of the disease. from october 1989 through august 1991, natural infections with flagellates were detected in 34 of 3,000 lutzomyia whitmani, five of 1,667 lu. migonei, three of 5,278 lu. wellcomei, one of 646 lu. shannoni, and one of 21 lu. evandroi. thirty-five infections were peripylarian (i.e., behind the pylo ... | 1994 | 8024061 |
| [evaluation of direct agglutination tests in the detection of leishmania (viannia) braziliensis in possible reservoirs of cutaneous american leishmaniasis in the state of ceará]. | in order to evaluate the aplicability of the direct agglutination test (dat) as a method of detection of the natural canine infection for leishmania (viannia) braziliensis, it was realized a study involving the serum of naive dogs from serra de baturite, ceara state, an endemic area of cutaneous leishmaniasis, and others from curitiba, parana state, a non endemic area. the results indicate the possibility of using this sorologic test to the epidemiologic research of the infection in the reservoi ... | 1996 | 8713609 |
| morphometric and phenetic studies of five geographical populations of lutzomyia whitmani (diptera: psychodidae) in brazil. | a morphometric survey examined adult specimens of lutzomyia whitmani (antunes & coutinho) captured at 5 municipalities in southeastern and northeastern brazil to compare the populations. the localities were ilhéus (bahia), martinho campos (minas gerais), corte de pedra (bahia), baturité (ceará), and amaraji (pernambuco): all are known foci of american cutaneous leishmaniasis. fifteen males and 15 females from each population were analyzed morphometrically for 42 and 37 characters, respectively. ... | 1999 | 10593089 |
| cutaneous leishmaniasis associated with extensive lymphadenopathy during an epidemic in ceará state, northeast brazil. | during an epidemic of cutaneous leishmaniais in northeast brazil a prospective study was conducted in order to assess clinical, parasitological and immunological features of cutaneous leishmaniasis in a representative sample of patients. a general examination was done and demographic and anthropometric data as well as numbers, duration, location, size, consistency and tenderness of enlarged lymph nodes and lesions recorded. hematologic and biochemical parameters as well as leishmania-specific an ... | 2005 | 15716050 |
| drought, smallpox, and emergence of leishmania braziliensis in northeastern brazil. | cutaneous leishmaniasis caused by leishmania (vianna) braziliensis is a major health problem in the state of ceará in northeastern brazil. we propose that the disease emerged as a consequence of the displacement of persons from ceará to the amazon region following the great drought and smallpox epidemic of 1877-1879. as the economic and social situation in ceará deteriorated, approximately 55,000 residents migrated to the amazon region to find work, many on rubber plantations. those that returne ... | 2009 | 19523291 |
| molecular identification of lutzomyia migonei (diptera: psychodidae) as a potential vector for leishmania infantum (kinetoplastida: trypanosomatidae). | visceral leishmaniasis (vl) in brazil is caused by the protozoan leishmania infantum. this parasite is transmitted by the bite of a female sand fly. the most important sand fly species in vl transmission is lutzomyia longipalpis. in fortaleza, the capital of ceará state, brazil, the simultaneous occurrence of lutzomyia migonei and l. longipalpis was detected in localities where vl transmission is observed. the purpose of this study was to determine conclusively if l. migonei can be found natural ... | 2016 | 26995718 |
