(Universidade Federal do Pará, 2012) ALENCAR, Maria de Nazaré Costa Santos; VALLINOTO, Antonio Carlos Rosário; http://lattes.cnpq.br/3099765198910740; BATISTA, Evander de Jesus Oliveira; http://lattes.cnpq.br/2206444845201080
Although the intestinal parasitosis are known since a long time and be studied since its identification, still constitute a challenge for their diagnosis and treatment. The delineation of the problem coming up in the necessity of investments in research for more accurate diagnosis, for the prompt intervention, to the existing cases and work for the prevention of risk factors that favor the emergence, maintenance and propagation of these agents. The knowledge that the host's immune competence is a limiting factor of parasitic load of various species, stimulated the research considering that the Mannosebinding lectin (MBL), a component of the complement system, is a key protein of the innate immune system, acting in the first line of defense against pathogens because it is considered acute phase. In this study, were colected 221 samples of individuals of both gender and varied ages at three different laboratories, in the period from January to April 2012. The profile of the population of the study are made and the analysis of the association between social and demographic factors with the entero-parasites and evaluated the influence of serum levels of Mannose-binding lectin (MBL) susceptibility of enteroparasitoses, distribution by age group and gender. Established also the comparison between serum concentrations of MBL of groups with identification of parasites. Statistically significant associations were observed when related protozoa E. histolytica and G.lamblia with the serum concentration of the MBL.

Gastrointestinal nematodes in ostriches, Struthio camelus, in different regions of the state of Rio de Janeiro, Brazil
(Universidade Federal do Pará, 2015-06) EDERLI, Nicole Brand; OLIVEIRA, Francisco Carlos Rodrigues de
The ratite group is composed of ostriches, rheas, emus, cassowaries and kiwis. Little research has been done on parasitism in these birds. The aim of this study was to determine the distribution of infections by gastrointestinal nematodes in ostriches in the state of Rio de Janeiro. For this, fecal samples were collected from 192 on 13 farms. From each sample, four grams of feces were used to determine the eggs per gram of feces (EPG) count, by means of the McMaster technique. Part of the feces sample was used for fecal cultures, to identify 100 larvae per sample. The results were subjected to descriptive central trend and dispersion analysis, using confidence intervals at the 5% error probability level in accordance with the Student t distribution, and Tukey’s test with a 95% confidence interval. The mean EPG in the state was 1,557, and the municipality of Três Rios had the lowest average (62). The city of Campos dos Goytacazes presented the highest mean EPG of all the municipalities analyzed. The northern region presented the highest mean EPG, followed by the southern, metropolitan, coastal lowland and central regions. Libyostrongylus species were observed on all the farms: L. douglassii predominated, followed by L. dentatus and Codiostomum struthionis.

Occurrence of eggs and oocysts of gastrointestinal parasites in passerine birds kept in captivity in Para State, Brazil
(Universidade Federal do Pará, 2016-12) MATOS, Paulo Cesar Magalhães; SILVA, Michele Bahia do Vale; SOUZA, Paulo Geovani Silva; LIMA, Danillo Henrique da Silva; MORAIS, Rodrigo de; FARIAS, Diana Maria de; ALVARENGA, Laís Cristina Oliveira; GABRIEL, Áurea Martins; OLIVEIRA, Wanessa Batista Lima; CAVALCANTE, Gustavo Góes; AMARAL, Alessandra Scofield
he objective of this study was to detect helminth eggs and protozoan oocysts in samples of feces from birds of the order Passeriformes in Para State, Brazil. Fecal samples were collected individually from 403 passerine birds seized and kept in captivity in Para State. Samples were processed by the double centrifugation technique in saturated sucrose solution and the coccidial oocyst-positive samples were submitted to sporulation in potassium dichromate 2.0%. Helminth eggs and/or protozoan oocysts were observed in 43.18% (174/403) of the fecal samples examined. Coccidial oocysts were detected in 93.68% (163/174) of the positive samples, whereas helminth eggs were observed in 10.34% (18/174) of the positive samples. Oocyst sporulation occurred in 43.56% (71/163) of the samples, and only Isospora spp. oocysts were detected. Nematode eggs of the superfamilies Trichostrongyloidea (4.60%; 8/174), Ascaridoidea (0.57%; 1/174), and Trichuroidea (0.57%; 1/174) were diagnosed in the positive samples. Cestoda eggs were diagnosed in 2.87% (5/174), whereas Trematoda eggs were detected in 2.30% (4/174) of positive samples. Passerine birds seized and kept in captivity in the visited local presented parasitism by intestinal helminths and protozoan, with a predominance of infection with coccidia of the gender Isospora.

Parasitismo intestinal em uma aldeia indígena Parakanã, sudeste do Estado do Pará, Brasil
(1998-09) MIRANDA, Rogério dos Anjos; XAVIER, Fábio Branches; MENEZES, Raimundo Camurça de
To determine the occurrence and epidemiological aspects of intestinal parasites among the Parakanã indigenous people in the Paranatinga settlement (in the eastern Amazon Region), parasitological tests were performed in April 1992 and February 1995. One fresh stool specimen was obtained and immediately processed using the Hoffman and direct methods. Some 126 samples were obtained in April 1992 (from a total population of 215 individuals). Some 80.2% (101) of those tested were infected with at least one species of intestinal parasite. Hookworms were found in 33.3%, Ascaris lumbricoides 42.8%, Trichuris trichiura 0.8%, and Strongyloides stercoralis 5.6%. Entamoeba histolytica and Giardia lamblia protozoans were found in 65.0% and 46.8% of those tested, respectively. A second parasitological survey was performed on 174 individuals (from a population of 253) in February 1995. 88.5% were infected. Note that prevalence in February 1995 was higher than in April 1992 (p = 0.04). It was lower for hookworms, E. histolytica, and G. lamblia, with no S. stercoralis (p<0.05). Despite provision of health care in the Paranatinga community, prevalence of intestinal parasites is still extremely high, suggesting that primary and secondary health care should be increased immediately.

(Universidade Federal do Pará, 2003) XAVIER, Fábio Branches; SILVEIRA, Luiz Carlos de Lima; http://lattes.cnpq.br/9383834641490219
The study show the prevalence of intestinal parasitosis, malnutrition and mercury exposure in childish population of Barreiras riverside community, Itaituba district: western of Pará state. To detect intestinal parasitosis in excrement was used Hoffmann Method. For diagnosis of malnutrition admit the recommended method by World Health Organization (WHO). The proportion of total mercury in specimen hair was obtained to Atomic Spectrofotometry Absorption. The results showed incrase of prevalence of Ascarís fumbrícoídes and Ancylostoma duodenafe. Malnutrition acute cases to total 2,4% of population. Children with high levels of total mercury come down to 43,5%. Did not exist relation between intestinal parasitosis and malnutrition.

Prevalência de enteroparasitoses e anemia e suas correlações com estado nutricional das crianças ribeirinhas do furo do Maracujá - Acará/PA
(Universidade Federal do Pará, 2011) FERNANDES, Adriana Prado; MARTINS, Luisa Caricio; http://lattes.cnpq.br/1799493244439769
In recent decades there has been recognition that the actions of disease prevention and promoting healthy lifestyles promoted in the child a full growth and development. Since these actions are only viable means of population studies that the child is inserted. However, these benefits become unmanageable children who live in coastal communities, since these studies are extremely scarce. It is known that anemia and intestinal parasitic infections affect child nutritional status thus hindering the full development. The study include 80 children aged 1-10 years, and a 45 (56%) were female and 35 (44%) were male. We had a high prevalence of intestinal parasites found in all these children. The parasites found were E. histolytica/dispar (36.8%), G. lamblia (31.2%), A. lumbricoides (23.2%), T. trichiura (4.8%), hookworm (2.4%) and passing S. stercoralis (1.6%). There was also a high prevalence of anemia (77.5%), noting that children of 1-5 years of age were the hardest hit. The correlation of anemia and deficiency of serum iron was significant (p = 0.0001), since 91% of children were anemic and iron deficiency. The most surprising about this study was that 72.5% of children were well nourished before both intestinal parasites and anemia. We did not observe almost no studies relating to these variables in children riverside, but only by what we watch and shows the results obtained in a context marked by precarious living conditions.
