Abstract We investigated the infection by pulmonary parasites in the lizard Ameiva ameiva (Teiidae) inhabiting the Environmental Protection Area of Araripe (APA-Araripe). A total of 45 specimens were collected in three areas between the cities of Várzea Alegre and Barbalha. A Pentastomid species (Raillietiella mottae) was parasitizing (nine specimens) a male of A. ameiva with a prevalence of 2.22% considering all lizards collected in the region and prevalence of 50% considering only rainforest environment. The Pentastomids infection rates shown in this study are similar to data found for infections of other insectivorous lizards. Raillietiella mottae is considered a generalist parasite, which uses insects as intermediate hosts. The results of this study represent the first record of a Pentastomid infecting this species of lizard in South America.
Resumo Neste estudo investigamos a infecção por parasitas pulmonares no lagarto teiídeo Ameiva ameiva (Teiidae) habitando a Área de Proteção Ambiental do Araripe - APA Araripe. Um total de 45 espécimes foram coletados em três áreas entre os municípios de Várzea Alegre e Barbalha. Uma espécie de pentastomida (Raillietiella mottae) estava parasitando (nove espécimes) um macho de A. ameiva com uma prevalência de 2,22%, considerando todos os lagartos da região, e uma prevalência de 50% considerando apenas a floresta úmida. A taxa de infecção por pentastomídeos demonstrado no presente estudo é semelhante aos dados de infecção encontrados para outros lagartos insetívoros. Raillietiella mottae é considerado um parasita generalista, que usa insetos como hospedeiros intermediários. O resultado do presente estudo representa o primeiro registro de um pentastomídeo infectando lagartos do gênero Ameiva na América do Sul.

The parameters of infection by lung parasites from two sympatric lizards, Mabuya arajara and Anolis brasiliensis, from the Atlantic Rainforest of the lower slope of Chapada do Araripe in Northeastern Brazil were analyzed between September, 2009 and July, 2010. A total of 202 lizards were collected. 125 specimens were from Mabuya arajara and 77 from Anolis brasiliensis. M. arajara was infected by the pentastomid Raillietiella mottae while A. brasiliensis was infected by the nematode Rhabdias sp., with an overall prevalence of 1.6% and 28.6%, respectively. The mean intensity of infection by Rhabdias sp. was 3.63 ± 2.58 (range 1-15). The body size and sex of lizards did not influence the intensity of infection by Rhabdias sp. The overall prevalence was also not different between males and females hosts in A. brasiliensis. Both Anolis brasiliensis and Mabuya arajara represent a new host to Rhabdias sp. and Raillietiella mottae, respectively.
Os parâmetros de infecção por parasitas pulmonares em dois lagartos simpátricos, Mabuya arajara e Anolis brasiliensis, da floresta úmida da encosta da Chapada do Araripe, Nordeste do Brasil, foram analisados entre setembro de 2009 e julho de 2010. Um total de 202 lagartos foi coletado, sendo 125 espécimes de Mabuya arajara e 77 de Anolis brasiliensis. M. arajara estava infectado pelo pentastomídeo Raillietiella mottae, enquanto A. brasiliensis apresentava infecção pelo nematódeo Rhabdias sp., com prevalência total de 1,6% e 28,6%, respectivamente. A intensidade média de infecção por Rhabdias sp. foi 3,63 ± 2,58 (amplitude 1-15). O tamanho e o gênero dos lagartos não influenciaram a intensidade de infecção por Rhabdias sp. A prevalência também não apresentou diferença entre machos e fêmeas em A.brasiliensis. Ambos, Anolis brasiliensis e Mabuya arajara, representam novos hospedeiros para Rhabdias sp. e Raillietiella mottae, respectivamente.

Sparganosis in humans is an incidental infection and is known to be associated with eating insufficiently cooked meat of frogs and snakes or drinking unboiled stream water. Although it can involve various internal organs, pulmonary and pleural involvement due to sparganum is rare. Because we recently experienced two cases involving lung parenchyma and pleura that were misdiagnosed as bacterial pneumonia and lung cancer, we herein intend to present them in detail.

We present data on pulmonary infection rates by parasites in the lizards Tropidurus hispidus Spix, 1825 and T. semitaeniatus (Spix, 1825) living sympatrically in the Chapada do Araripe mountain Range, northeastern Brazil. We found no parasite pulmonary infection in T. semitaeniatus. However, two pulmonary parasite species were found in the T. hispidus hosts, the pentastomid Raillietiella mottae Almeida, Freire and Lopes, 2008 and the nematode Rhabdias sp. Overall prevalence was 5 percent. Prevalence of R. mottae was 2.5 percent and corresponded to only one parasite on each infected host. Prevalence of Rhabdias sp. was 2.5 percent and the range of infection was 1-2 parasites per host. This represents the first record of Rhabdias infecting lizards of the family Tropiduridae in the Neotropical region. Furthermore, we present a comparison of parameters of infection by pulmonary parasites including some recent studies in Brazil.
Apresentamos dados sobre taxas de infecção pulmonar por parasitas nos lagartos Tropidurus hispidus e T. semitaeniatus que vivem simpatricamente na encosta da Chapada do Araripe, situada na região Nordeste do Brasil. Não encontramos infecção parasitária nos pulmões dos espécimes de T. semitaeniatus. Entretanto, foram encontradas duas espécies de parasitas nos hospedeiros T. hispidus, os pentastomídeos Raillietiella mottae e os nematódeos Rhabdias sp. A prevalência geral de infecção foi de 5 por cento. A prevalência de infecção de R. mottae foi de 2,5 por cento correspondendo a apenas um parasita por hospedeiro. A prevalência de infecção de Rhabdias sp. foi de 2,5 por cento e a amplitude de infecção de 1-2 parasitas por hospedeiros. Esses resultados compreendem o primeiro registro de Rhabdias infectando lagartos da família Tropiduridae em toda a região Neotropical. Apresentamos também uma comparação com os parâmetros de infecção pulmonar por parasitas incluindo os estudos mais recentes no Brasil.

A esquistossomose é uma doença que, no Brasil, é causada pelo Schistosoma mansoni e transmitida através da água por moluscos do gênero Biomphalaria. Essa espécie ocorre na África, nas Antilhas e na América do Sul. O parasita, ao atingir a fase adulta de seu ciclo biológico no sistema vascular do homem, alcança as veias mesentéricas. Cada fêmea põe cerca de 400 ovos por dia, e estes, a partir da submucosa, chegam à luz intestinal. Há relatos de casos a respeito de ovos de S. mansoni nos pulmões de pacientes sem evidência de fibrose hepática. Relatamos um caso dessa forma atípica de apresentação da doença. O paciente apresentava dor torácica não-ventilatóriodependente, perda ponderal significativa e tosse seca. A TC de tórax mostrou uma tumoração irregular no lobo inferior esquerdo, mas somente a biópsia pulmonar evidenciou ovos de S. mansoni degenerados. O paciente não apresentava sinais clínicos de hipertensão pulmonar ou portal, as quais tampouco foram diagnosticadas através de exames.
Schistosomiasis is a disease that, in Brazil, is caused by Schistosoma mansoni and is transmitted by snails of the genus Biomphalaria. This species occurs in Africa, the Antilles and South America. The parasite, developing to the adult stage in the vascular system of the host, migrates to the mesenteric veins. Each female lays approximately 400 eggs per day, and these travel from the submucosa to the intestinal lumen. There have been reported cases in which S. mansoni eggs were identified in the lungs of patients with no evidence of liver fibrosis. We report a case with this atypical presentation of the disease. The patient presented nonpleuritic chest pain, significant weight loss and dry cough. A CT scan revealed an irregular tumor in the left lower lobe. However, a lung biopsy revealed non-viable S. mansoni eggs. The patient presented no clinical signs of pulmonary or portal hypertension; nor was either identified through diagnostic tests.

O comprometimento pulmonar na paracoccidioidomicose é muito freqüente, podendo até ser a única manifestação da doença. Apresentamos um caso de paracoccidioidomicose pulmonar (forma cavitária) em uma mulher de 46 anos de idade. Em virtude da prevalência elevada da paracoccidioidomicose em nosso país e das seqüelas que a doença pode causar, os autores enfatizam a importância do seu diagnóstico.

Hepatic Schistosoma mansoni periovular granulomas undergo changes in size, cellular composition and appearance with time. This phenomenom, known as "immunological modulation", has been thought to reflect host immunological status. However, as modulation has not been observed outside the liver, participation of local factors, hitherto little considered, seems crucial. Components of the extracellular matrix of periovular granulomas of the mouse were particularly studied in three different organs (liver, lung and intestine) and during three periods of infection time (acute, intermediate and chronic) by means of histological, biochemical and imunofluorescence techniques, while quantitative data were evaluated by computerized morphometry, in order to investigate participation of local factors in granuloma modulation. Results confirmed modulation as a exclusively hepatic phenomenom, since pulmonary and intestinal granulomas, formed around mature eggs, did not change size and appearance with time. The matricial components which were investigated (Type I, III and IV collagens, fibronectin, laminin, proteoglycans and elastin) were found in all granulomas and in all organs examined. However, their presence was much more prominent in the liver. Elastin was only found in hepatic granulomas of chronic infection. The large amount of extracellular matrix components found in hepatic granulomas was the main change responsible for the morphological aspects of modulation. Therefore, the peculiar environment of the liver ultimately determines the changes identified in schistosomal granuloma as "modulation".
