[Ab] Resumo:OBJECTIVE: The aim of this study was to detect the presence of parasites in environmental waters in Samsun and its districts. METHODS: At the center of Samsun, 13 stations were determined. The research was performed between March 2012 and February 2013, and every month, water samples were collected on the dates stated. The samples were stained with Kinyoun acid-fast, modified trichrome, and trichrome dyes after examining with the direct bond. The preparations were evaluated in terms of parasitologic under a light microscope. RESULTS: Totally, 180 of 228 water samples analyzed were from streams; of these, 48 were drinking water samples. The following were found: 142 Giardia spp., 132 Cryptosporidium spp., 56 Cyclospora spp., 38 microsporidia, 47 Blastocystis spp., 38 Entamoeba coli cysts, 18 Dientamoeba, 9 Chilomastix, 9 Strongyloides spp., and 6 hookworms. CONCLUSION: The widespread use of animal husbandry and agriculture in the region and the use of stream surroundings as a grazing area increase the presence of some determined protozoa during a certain period. Parasitological studies in humans and animals in the region should be conducted, and control programs should be applied.

[Ab] Resumo:Parasitosis analysis at regional levels is simplified by the use of the Geographic Information System (GIS), which enables the identification of areas with different degrees of vulnerability. We analyzed the spatial distribution of intestinal parasites in La Plata district and their relationship with socio-environmental conditions in order to identify areas with different degrees of epidemiological risk. An epidemiological survey was completed; stool samples were collected and analyzed by Ritchie's method. Levels of precariousness and vulnerability (Iv rate) were calculated and compared to the parasitological results. Parasitological and environmental analysis were carried out on a total of 653 individuals, of whom 585 (89.6%) were children and 68 (10.4%) adults. The analysis indicated that the most vulnerable (Iv = 3-4) were those located in areas with less access to urban infrastructure services. The Iv was strongly associated with the overall prevalence of intestinal parasitosis and the 4 pathogenic species related to the fecal contamination of the environment: Trichuris trichiura, Ascaris lumbricoides, Hymenolepis nana and Giardia lamblia (p < 0.01). On the other hand, Enterobius vermicularis, a parasite not related to the sanitary condition of its host, was not associated with the Iv. Statistical association between poverty and parasitosis was noted; the greater the Iv, higher the incidence of parasites (p < 0.01). GIS allowed zoning socio-environmental variables in an increasing gradient of unfavorable conditions and their relationship to the presence of pathogenic species. The continuity of these studies in different regions of Argentina contributes to the determination of health risk areas.

[Ti] Título:Multigene phylogenies of diverse Carpediemonas-like organisms identify the closest relatives of 'amitochondriate' diplomonads and retortamonads.

[Ab] Resumo:Diplomonads, retortamonads, and "Carpediemonas-like" organisms (CLOs) are a monophyletic group of protists that are microaerophilic/anaerobic and lack typical mitochondria. Most diplomonads and retortamonads are parasites, and the pathogen Giardia intestinalis is known to possess reduced mitochondrion-related organelles (mitosomes) that do not synthesize ATP. By contrast, free-living CLOs have larger organelles that superficially resemble some hydrogenosomes, organelles that in other protists are known to synthesize ATP anaerobically. This group represents an excellent system for studying the evolution of parasitism and anaerobic, mitochondrion-related organelles. Understanding these evolutionary transitions requires a well-resolved phylogeny of diplomonads, retortamonads and CLOs. Unfortunately, until now the deep relationships amongst these taxa were unresolved due to limited data for almost all of the CLO lineages. To address this, we assembled a dataset of up to six protein-coding genes that includes representatives from all six CLO lineages, and complements existing rRNA datasets. Multigene phylogenetic analyses place CLOs as well as the retortamonad Chilomastix as a paraphyletic basal assemblage to the lineage comprising diplomonads and the retortamonad Retortamonas. In particular, the CLO Dysnectes was shown to be the closest relative of the diplomonads + Retortamonas clade, with strong support. This phylogeny is consistent with a drastic degeneration of mitochondrion-related organelles during the evolution from a free-living organism resembling extant CLOs to a probable parasite/commensal common ancestor of diplomonads and Retortamonas.

[Ab] Resumo:Viral, bacterial and parasitological infections in rats and mice used in biomedical research continue to occur despite improved housing and biosurveillance. The presence of disease in laboratory animals can lead to spurious results for research undertaken in universities, research institutes and the pharmaceutical industry. Here the authors report the results of serological, microbiological, parasitological and molecular tests done on mice and rats from Australasia submitted to a rodent health monitoring laboratory (Cerberus Sciences) from 2004 to 2009. In tested mice, norovirus was the most prevalent virus and ectromelia virus was the least prevalent virus. In tested rats, pneumonia virus of mice was the most prevalent virus and adenoviruses 1 and 2 were the least prevalent viruses. In mice, Helicobacter hepaticus was the most prevalent bacterium, and in rats, Proteus spp. were the most prevalent bacteria. The most common positive helminthological finding in mice and rats was the presence of all pinworms (including Aspicularis spp. and Syphacia spp.). The most common positive protozoan findings in mice and rats were Chilomastix spp. and Trichomonads.

[Ab] Resumo:In Sucre state, the Manzanares river is threatened by domestic, agricultural and industrial activities, becoming an environmental risk factor for its inhabitants. In this sense, the presence of protozoans in superficial waters of tributaries of the Manzanares river (Orinoco river, Quebrada Seca, San Juan river), Montes municipality, Sucre state, as well as the analysis of faecal samples from inhabitants of towns bordering these tributaries were evaluated. We collected faecal and water samples from may 2006 through april 2007. The superficial water samples were processed after centrifugation by the direct examination and floculation, using lugol, modified Kinyoun and trichromic colorations. Fecal samples where analyzed by direct examination with physiological saline solution and the modified Ritchie concentration method and using the other colorations techniques above mentioned. The most frequently observed protozoans in superficial waters in the three tributaries were: Amoebas, Blastocystis sp, Endolimax sp., Chilomastix sp. and Giardia sp. Whereas in faecal samples, Blastocystis hominis, Endolimax nana and Entaomeba coli had the greatest frequencies in the three communities. The inhabitants of Orinoco La Peña turned out to be most susceptible to these parasitic infections (77.60%), followed by San Juan River (46.63%) and Quebrada Seca (39.49%). The presence of pathogenic and nonpathogenic protozoans in superficial waters demonstrates the faecal contamination of the tributaries, representing a constant focus of infection for their inhabitants, inferred by the observation of the same species in both types of samples.

[Ti] Título:Gastrointestinal parasites of the chimpanzee population introduced onto Rubondo Island National Park, Tanzania.

[Ab] Resumo:The release of any species into a novel environment can evoke transmission of parasites that do not normally parasitize the host as well as potentially introducing new parasites into the environment. Species introductions potentially incur such risks, yet little is currently known about the parasite fauna of introduced primate species over the long term. We describe the results of long-term monitoring of the intestinal parasite fauna of an unprovisioned, reproducing population of chimpanzees introduced 40 years earlier (1966-1969) onto Rubondo Island in Lake Victoria, Tanzania, a non-native habitat for chimpanzees. Two parasitological surveys (March 1997-October 1998 and October 2002-December 2005) identified Entamoeba spp. including E. coli, Iodamoeba buetschlii, Troglodytella abrassarti, Chilomastix mesnili, Trichuris sp., Anatrichosoma sp., Strongyloides spp., Strongylida fam. gen. sp., Enterobius anthropopitheci, Subulura sp., Ascarididae gen. sp., and Protospirura muricola. The parasite fauna of the Rubondo chimpanzees is similar to wild chimpanzees living in their natural habitats, but Rubondo chimpanzees have a lower prevalence of strongylids (9%, 3.8%) and a higher prevalence of E. anthropopitheci (8.6%, 17.9%) than reported elsewhere. Species prevalence was similar between our two surveys, with the exception of Strongyloides spp. being higher in the first survey. None of these species are considered to pose a serious health risk to chimpanzees, but continued monitoring of the population and surveys of the parasitic fauna of the two coinhabitant primate species and other animals, natural reservoir hosts of some of the same parasites, is important to better understand the dynamics of host-parasite ecology and potential long-term implications for chimpanzees introduced into a new habitat.
