Revista de Saúde Pública , 2002,
Abstract: OBJETIVO: Verificar as espécies de dípteros muscóides capazes de veicular ovos e larvas de helmintos e avaliar o potencial de contamina o dos dípteros capturados. MéTODOS: A pesquisa foi realizada em dois pontos distintos do Jardim Zoológico da cidade do Rio de Janeiro, RJ, no período de maio de 1996 a abril de 1998. As capturas dos dípteros foram realizadas semanalmente com armadilhas contendo peixe em putrefa o, que permaneceram expostas durante uma hora nos dois pontos: local 1- próximo à lixeira do zoológico e o local 2- perto do recinto do hipopótamo e das aves de rapina. Foram capturadas 41.080 moscas, sendo a espécie Chrysomya megacephala mais representativa com 69,34%, seguida de Chrysomya albiceps 11,22%, Musca domestica 7,15%, Chrysomya putoria 4,52%, Fannia sp. 3,12%, Ophyra sp. 2,53% e Atherigona orientalis 2,08%. As moscas capturadas tiveram a superfície dos corpos lavadas com água destilada e os tubos digestivos dissecados. RESULTADOS: Das espécies estudadas, C. megacephala e M. domestica apresentaram maior quantidade de ovos de helmintos na superfície do corpo e no conteúdo intestinal. Ovos de Ascaridoidea e Trichinelloidea prevaleceram no conteúdo intestinal de C. megacephala. Dos ovos de helmintos encontrados na superfície do corpo e no conteúdo intestinal foram identificados: Ascaris sp., Toxascaris sp., Toxocara sp., Trichuris sp., Capillaria sp., Oxiurídeos, Triconstrogilídeos e Acantocephala. Também foram encontradas larvas de helmintos na superfície do corpo dos dípteros. Houve diferen as significativas (nível de 5%, pelo teste F) entre os diferentes pontos de capturas em rela o ao número de ovos de helmintos encontrados nos dípteros. CONCLUS ES: As fezes dos animais do jardim zoológico, encontradas freqüentemente nos abrigos e lixeiras, contribuíram para a prolifera o dos dípteros muscóides, que assumem importante papel na veicula o de ovos de helmintos, principalmente pelo contato direto do corpo do díptero com o alimento dos animais.

Abstract: objective: to assessmuscoid dipterae species who are able to carry helminth eggs and larvae and to evaluate the potential contamination of trapped dipterae. methods: the study was conducted in two different sites of the zoological garden of rio de janeiro from may 1996 to april 1998. flies were captured weekly using traps containing putrefied fish, left out in the open for an hour at two sites in the zoo: site 1 was next to the garbage and site 2 was near the hippopotamus and birds of prey cages. of the 41,080 flies captured, chrysomya megacephala was the most representative species (69.34%), followed by chrysomya albiceps (11.22%), musca domestica (7.15%), chrysomya putoria (4.52%), fannia sp. ( 3.12%), ophyra sp. ( 2.53%), and atherigona orientalis (2.08%). captured flies had their body surface washed out with distilled water and their gut dissected. results: among the species studied, c. megacephala and m. domestica presented higher helminth eggs on their body surface and in their intestinal content. ascaroidea and trichinelloidea eggs prevailed in the intestinal content of c. megacephala. the helminth eggs found on the body surface and in the intestinal content were identified as ascaris sp., toxascaris sp., toxocara sp., trichuris sp., capillaria sp., oxyuridae, trichostrongylidae and acantocephala. besides eggs it was also found helminth larvae on the body surface of flies. there were significant differences between the two different capture sites related to the number of helminth eggs found on the flies. conclusions: faeces of zoo animals frequently found in their cages and in the zoo garbage contributed to the proliferation of muscoid dipterans who play an important role in spreading helminth eggs, mainly by direct contact of the flies' body with the animals' food.

Abstract: the pathogens associated with ants at the teaching hospital of the federal university of the triangulo mineiro, in uberaba, mg, were studied. three species of ants were identified: tapinoma melanocephalum, pheidole sp and paratrechina longicornis. the principal microorganisms found were staphylococcus sp, gram-positive bacilli, pseudomonas sp and micrococcus sp. the results from the collections were analyzed according to the number of colonies and the different microorganisms isolated, using student's t test. the statistical analysis showed that there was a significant difference only with regard to staphylococcus sp. (p =0.005). it is possible that ants and pathogenic agents have mutualistic associations, and that analysis of such relationships may lead to new pest control strategies, with an emphasis not only on the insects but also especially on which agent is associated with these insect species.

Revista Panamericana de Salud Pública , 2010, DOI: 10.1590/S1020-49892010000600002
Abstract: objectives: to determine 1) the degree of soil contamination by parasites; 2) the prevalence of contaminated samples; 3) the overall number of parasitic forms, by distance between the collection site and the domicile; 4) the mean number of parasite forms per peri-household area; and 5) the variables associated with the total number of parasite forms. methods: soil samples were collected in the peridomicile of 18 (out of a total sample of 63) and 22 (out of 190) residences of the faxinal and ivaí indigenous territories (its), respectively, from march 2005 through october 2006, and evaluated by the methods of baermann, modified faust et al., and lutz. results: the overall prevalence of samples contaminated by enteroparasites of humans or of animals with zoonotic potential was 75.7% (84 out of 111) in faxinal and 96.2% (127 out of 132) in ivaí. the most prevalent parasites were ascaris spp., isospora spp., and toxocara spp. positive statistical associations were observed between the number of parasitic forms per domicile and the following variables: time of year (season), the presence of bathrooms in the domicile, and the presence of excrement on peridomiciliar soil. conclusions: the high level of soil contamination in faxinal and ivaí 1) constitutes a potential source of parasitic infection and 2) suggests that the treatment of human and animal excreta continues to be inadequate.

Abstract: Cockroaches, Blattodea order insects, act as an important mechanical vector for lots of pathogenic microorganism agents, including bacteria, protozoa, worms, fungi, and viruses amongst humans and animals. Polyphaga aegyptica is a rare species of cockroaches than the common cockroaches. The aim of this study was to isolate and identify bacteria that are picked up by P. aegyptica over the human and animal premises. In this study totally five P. aegyptica were collected to isolate their bacteria, from the house in Ahvaz SW Iran using common bacteriology methods. The isolated bacteria in this study were Escherichia coli, Klebsiella pneumoniae, Neisseria species, Bacillus cereus, B. subtilis and Staphylococci aureus based on sampling of external body and feces pellets of Egyptian cockroaches. The medical importance of P. aegyptica can be referred to transmitting medical importance reported bacteria in the present study.

Abstract: Tunneling behavior and the spatial dispersion of tunnels constructed by the subterranean termites Coptotermes formosanus Shiraki and Coptotermes gestroi (Wasmann) (formerly known as C. vastator Light) (Blattodea: Rhinotermitidae) were examined in foraging arenas. The results indicated that these two termite species construct quantitatively different tunnel systems, supporting visual observations made in earlier studies. Coptotermes gestroi constructed thin, highly branched tunnels, while C. formosanus tended to construct wider and less branched tunnels. Tunnels of C. gestroi showed more spatial dispersion than those of C. formosanus, and this species constructed a larger number of tunnels compared to C. formosanus. The presence or absence of food (wood) within the arena did not influence the tunneling pattern of either species. Although previous observations have suggested that these two termite species exhibit different tunneling behaviors; this is the first quantification of the differences. Comparative studies of the foraging behavior of subterranean termite species contribute to our understanding of their distribution and ecology and may help to improve pest management programs, particularly those based on placement of toxic baits. Moreover, differences in tunneling patterns may reflect different foraging strategies optimized for either tropical (C. gestroi) or subtropical/temperate (C. formosanus) environments.
