Zoonotic visceral leishmaniasis (ZVL), caused by protozoans of the genus Leishmania, it is a worldwide of great importance disease. In the northeast region of Brazil, the state of Alagoas has an endemic status for ZVL. Thus, this work aimed to analyze the epidemiological situation of human and canine visceral leishmaniasis in Alagoas, Northeast, Brazil, from 2007 to 2013. We conducted a descriptive, observational, retrospective study using secondary data from the Notifiable Diseases Information System, the Center of Zoonosis Control of Maceió, and the Central Laboratory of Public Health of Alagoas. During the studied period, it was observed that the highest incidence of human visceral leishmaniasis was in 2011 and the lowest in 2013. On the other hand, canine visceral leishmaniasis had its highest incidence in 2007 and its lowest in 2012. Of the 55 municipalities in the State of Alagoas that showed human visceral leishmaniasis (HVL), São José da Tapera presented an average of 4.4 cases over the past five years, being classified as of intense transmission. Regarding canine visceral leishmaniasis, in the same studied period, 45,112 dogs were examined in the State, of which 4,466 were positive. It resulted, thus, in a 9.9% positivity rate. Conclusions: Our data are important because canine infection is an important risk factor for the human disease. Keywords

This study quantifies phenolic and flavonoid compounds and evaluates the antioxidant activity by the DPPH (2,2-diphenyl-1-picrylhydrazyl) method, also identifying some secondary metabolites of R. sativus under organic fertilization and water stress. For this, a greenhouse experiment was carried out with the preparation of plant extracts (leaves and roots), quantification of phenolic and flavonoid compounds, analysis of antioxidant activity, and phytochemical screening. Different classes of secondary metabolites (catechins, steroids, saponins, among others) were identified. The DPPH method showed that the leaf extract has higher DPPH radical scavenging activity. The leaf extract had a high content of phenolic compounds, especially in treatments without water stress, either with organic fertilization (1925.59 mg GAE/g extract) or with mineral fertilization (2058.47 mg GAE/g extract). For root extracts, R. sativus developed under water stress and organic fertilization showed higher phenolic content (1383.24 mg GAE/g extract). Regarding flavonoid content, the root extract that showed the highest concentration corresponded to the treatment under water stress and without fertilization (82.1 mg QE/g extract). Therefore, radish was shown to be rich in bioactive compounds and with antioxidant potential in both its leaves and roots.

This study aimed to determine the frequency of infection by intestinal protozoa diagnosed in patients from a clinical analysis laboratory in Maceió, Alagoas, Brazil. This was a retrospective descriptive study, using a database of stool examination results from July to December 2015. The study population consisted of males and females of all ages, from the greater area of Alagoas. Data on epidemiological variables such as age and gender were obtained using a collection instrument. Protozoan species were identified from stool examinations. Results on the prevalence of intestinal parasites are described as simple and relative frequencies. We examined a total of 1277 stool samples, of which 12.69% were positive for one or more protozoa. 43.83% were from men and 56.17% were from women. Endolimax nana was the most prevalent (59.22%) protozoan species followed by Entamoeba coli (23.45%). Although non-pathogenic, they indicate fecal contamination of drinking water. The highest number (23.46%) of infected individuals was observed among children in the 0 to 11 years age group. A high prevalence (93.83%) of monoparasitism was noted. We concluded that there was a high frequency of infection and a high prevalence of E. nana. Infections were more common in women than in men. Our results emphasize the need for preventive measures to control intestinal parasitic infections.
