RESUMO

The aim of the present study was to analyze the status of the American Tegumentary Leishmaniasis (ATL) in the state of Rio de Janeiro, from 2004 to 2013, through its spatiotemporal distribution. We also described variables considered relevant to the epidemiology of the disease, such as the clinical form, gender, ethnic group, age group, and progression of disease. This is a descriptive study, which used notified secondary data from the Brazilian Information System of Notifiable Diseases (SINAN), Ministry of Health, Brazil, regarding confirmed diagnoses. To help the calculation of coefficients of detection and mortality, we used population data from the Brazilian Institute of Geography and Statistics (IBGE). We analyzed 1,470 cases of ATL with the predominance of the cutaneous clinical form (1,292/87.89%). The data has also revealed seven deaths, a predominance of males (922/62.72%), and a higher incidence of ATL in the white ethnic group (731/49.72%). We observed a high incidence of ATL in the group of 20 - 39 years old (477/32.44%). We concluded that there was a decrease in the number of ATL cases in the state of Rio de Janeiro, based on a coefficient of detection of 1.44/100.000 inhabitants in 2004 decreasing to 0.20/100.000 inhabitants in 2013. The localities with the highest occurrences of ATL were the metropolitan region (843 cases) and the municipality of Rio de Janeiro (740 cases). In 2005, the highest incidence of the disease was observed (351 cases) in the study. Among the variables selected to describe the epidemiology of the disease, the following categories: cutaneous clinical form, male patients, white ethnic group, and the age group of 20 - 39 years old were more affected than the others.

RESUMO

Background: Rhipicephalus (Boophilus) microplus (Canestrini, 1887) traditionally known as cattle tick, is the species that most affects cattle productivity levels in Brazil. The parasite causes annual losses up to US$ 2 billion. Despite several researches carried out all over the globe, it still presents great challenge, especially due to evidence of resistance to chemical products used in plague control. The goal of this project was to verify in vitro efficiency of pesticides in controlling R. (B.) microplus, at Campos dos Goytacazes municipality, Rio de Janeiro, Brazil, in 2007. Materials, Methods & Results: The in vitro test used was the one recommended by FAO's (Food and Agriculture Organization) World Acaricides Resistance Reference Center (WARRC). Engorged females were manually collected off the ground from stalls and separated in two treatments, amitraz 12.5% (commercial dilution 1:500 = 2 mL/1000 mL) and cypermethrin 15% (commercial dilution 1:1000 = 1 mL/1000 mL), each one with six groups of ten parasites. A different solution - 1:10, 1:100, 1:1000, 1:100000 and 1:1000000 - for both acaricides tested was used on each group, and for control was used potable water. The test was started from the highest dilution. Each dilution was repeated three times simultaneously. Recommended dilutions in the research were in the protocol. Each group of engorged females was weighted in analytical precision scale with equivalence in measurement of weights and, further, transferred to a Becker, containing 50 mL of the solution to be tested, previously prepared. The Becker was kept in constant agitation for five min. Afterwards, the engorged females were put upon towel paper (15 cm²) in order to remove excess of the product, being then transferred to Petri plates (100 mm x 20 mm height), identified and taken to a BOD incubator at 28°C (± 1) and 80% humidity. After oviposition, the number of eggs laid by each group were weighted and inserted in previously adapted plastic syringes, identified and taken again to the same incubator. We conducted the reading of the eggs hatching percentage after 30 days, with a stereoscopic microscope, using as reference the hatching observed in the control group that was kept on a different incubator. The reproduction efficiency (RE) was calculated using the equation; RE = eggs' weight/female's weight x % hatching x 20.000. The control percentage was calculated following the equation, considering the arithmetic mean of three repetitions: % control = RE (non-treated) - RE (treated)/RE non-treated x 100. We obtained as results after a 30 days analysis, a mean percentage of total efficiency of 96.60% for amitraz 12.5% and of 98.00% for cypermethrin 15% in the control of eggs hatching. Discussion: The amitraz 12.5% and the cypermethrin 15% presented excellent results in controlling wild strains of R. (B.) microplus that attacks cattle at Campos dos Goytacazes municipality, Rio de Janeiro, agreeing with FAO's WARRC and the Ministério da Agricultura, Pecuária e Abastecimento (MAPA), which established a legally accepted efficacy for acaricides being equal or superior to 80.00% and 95.00%, respectively, over tick strains. Hence the importance of this pioneer project in the region and its contribution to the subject extension.

RESUMO

Realizou-se estudo soroepidemiológico sobre Leishmaniose, zoonose de grande importância, envolvendo população canina de rua, pertencente ao município de Campos dos Goytacazes, estado do Rio de Janeiro, Brasil, considerando a ocorrência de um caso humano no ano de 2000. Esta pesquisa foi desenvolvida com o objetivo de observar a eficiência do teste “Enzyme Linked Immunosorbent Assay” (ELISA), para detecção de anticorpos contra Leishmania sp. em cães. Inicialmente coletou-se 5 ml de sangue da veia ulnar, para obtenção do soro, de 370 cães errantes, no período de 2000 a 2001, capturados pelo Centro de Controle de Zoonoses e Vigilância Ambiental (CCZ) do município de Campos dos Goytacazes. Dos cães pesquisados 13 (3,50%) amostras foram positivas e 357 (96,50%) foram negativas. O teste sorológico ELISA para Leishmaniose Canina, além de ser eficiente na detecção de anticorpos anti-Leishmania sp., é um bom teste para ser utilizado a campo em triagens soroepidemiológicas(campanhas de vacinação anti-rábica), devido à sua praticidade e baixo custo. O município de Campos dos Goytacazes, devido à ocorrência de um caso humano, passa então a ser considerado área endêmica para Leishmaniose(AU)

RESUMO

Sabendo-se da importância das miíases como um fator complicante das lesões cutâneas, e por apresentarem elevada incidência no Estado do Rio de Janeiro, idealizou-se testar a eficácia, praticidade e segurança de uma base química, conhecida como nitenpyram, no tratamento dessas ectoparasitoses. O nitenpyram é um farmáco utilizado como adulticida para pulgas, e neste trabalho buscou-se sua adaptação em 27 cães domiciliados que apresentavam miíases, com diferentes graus de parasitismo. Como resultado obteve-se 100% de eficácia da eliminação larval, independente da quantidade e do estágio, inclusive tendo uma resposta inicial rápida, com 88,9% dos cães com lesões livres em até 24 horas após a primeira dosagem. A exteriorização das larvas ocorreu por si só, sem manipulação, e em período médio de 20 a 37 minutos após a dosificação. O fármaco mostrou-se excelente, sem quaisquer efeitos colaterais e prático, uma vez que sua administração é oral e dispensa a retirada manual das larvas, forma essa dolorosa, pois, às vezes, é preciso que o animal esteja anestesiado. Os cães tratados apresentaram uma cicatrização mais rápida das lesões(AU)
