Calyptospora species are coccids that commonly cause liver infections in fish all around the world. This paper describes the morphology and histopathological characteristics of liver infection caused by Calyptospora sp. in black piranha Serrasalmus rhombeus, from the Capim River, in the municipality of Ipixuna do Pará, state of Pará (Brazil). Specimens were collected, analyzed and necropsied and tissue fragments containing parasites were prepared for histology and scanning electron microscopy. Parasitism was detected in 33.0% of the analyzed specimens, which had spherical oocysts in the liver, with four pyriform sporocysts presenting sporozoites internally. A histological examination revealed oocysts positioned close to blood vessels, causing necrosis and degeneration of hepatic parenchyma, while the presence of mononuclear cell infiltrate and melanomacrophages indicated the onset of an inflammatory process. This is the first record of the genus Calyptospora in fish from the Capim River.The effect of four diets on the performance of Dorper lambs that were artificially mix-infected with 1000 infective larvae (L3) of Haemonchus contortus and 1000 L3 of Trichostrongylus colubriformis every three days for 12 weeks was evaluated. For each diet, one infected group (n = 7) and one control group (n = 4) were set up. The four diets contained the following proportions of hay (H) and concentrate (C) Diet 1 - 100%H; Diet 2 - 75%H25%C; Diet 3 - 50%H50%C; Diet 4 - 25%H75. All the infected groups showed decreases in mean packed cell volume (PCV) and total plasma protein, especially the Diet 1-infected, which was also the group with the highest fecal egg count. The diets and infection had significant effects (P less then 0.05) on daily body weight gain (DBWG), cold carcass weight and daily food consumption. The control and infected groups had mean DBWG (in kg), respectively, of 0.048 and 0.025 with Diet 1; 0.082 and 0.067 with Diet 2; 0.188 and 0.189 with Diet 3; and 0.303 and 0.221 with Diet 4. Tacrolimus in vivo In conclusion, the infection affected the productive performance regardless of the diet; however, with increased metabolizable protein and energy, the risk of occurrence of anemia and hypoproteinemia diminished.Myiopsitta monachus is an invasive psittacine with wide distribution due to the pet trade. Its large communal nests and synanthropic nature contribute to its successful colonization of cities, from where it seems to be expanding in range and numbers. This is relevant with regard to pathogens that invasive species may harbor, especially when host populations thrive. We aimed to identify an abundant mite found in invasive monk parakeet chicks that had been collected in Santiago during 2017 and 2018. Through morphological and molecular identification of the 18S ribosomal RNA gene, we confirmed the presence of Ornithonyssus bursa. This was the first report of this mite in Chile. This mite is common in native and invasive monk parakeet populations and may affect other birds, including domestic fowl. Further, this mite bites people and can be a potential vector of pathogens such as bacteria or viruses. We conclude that this parasite was likely introduced with the parakeet and discuss possible ecological, health and economic consequences of this new potential pest.Ectoparasitic infestation in dairy cattle, the most common being Rhipicephalus (Boophilus) microplus, causes significant loss in production. The control of ectoparasites often occurs incorrectly, resulting in resistance to the active ingredients and residues in milk. To understand of acaricide use in the microregion of Alfenas, Minas Gerais (Brazil), questionnaires were applied to the owners of 100 dairy farms in the region and were selected randomly. Dairy farms were allocated according to production scale up to 150 liters/day, 151-400 liters/day and more than 400 liters/day. The interviewees were asked about production characteristics, acaricide management and active ingredients. The interview answers were subjected to descriptive analysis. Results showed that all properties, independent of production-scale, used acaricides. The most cited was Cypermethrin Chlorpyrifos Citronellal (31%), Fluazuron (18.6%) and Fipronil (17%). Among the interviewed, 41,1% use drugs that have restrictions that are not allowed in legislation for use in lactating dairy cows (fluazuron, fipronil, ivermectin). 15% affirmed they weren't aware of the "withdrawal period" of medication and 73% change in the active ingredient used. In order to revert this antiparasitic drug's resistance situation and contamination of milk with drug residues, it is necessary to focus on the awareness of milk producers and training of labor.

The aim of this study is to determine the healthy lifestyle behaviors and e-health literacy levels of adolescents.

A descriptive research design was used in this study. It was conducted with a total of 390 students in the Faculty of Health Sciences. The data were collected using a personal information form, the Healthy Lifestyle Behaviors Scale II and the e-Health Literacy Scale for Adolescents. For data analysis, descriptive analyses, t-test, variance, Kruskal-Wallis, the Mann-Whitney U and Pearson Correlation tests were used. Necessary approvals were obtained to conduct this study.

The present study found that the e-Health Literacy Scale mean score of adolescents was 27.51 and their HLBS-II mean score was 129.01. A positive significant relationship was found between the e-health literacy and healthy lifestyle behavior in adolescents.

This study emphasizes the importance of e-health literacy in developing nursing procedures designed to increase the healthy lifestyle behaviors of adolescents.

This study emphasizes the importance of e-health literacy in developing nursing procedures designed to increase the healthy lifestyle behaviors of adolescents.Health status indicators are an important tool for monitoring the performance of public health actions, identifying trends and priority regions for resource allocation. An R package was developed in order to increase the feasibility of handling and analyzing health status indicator data. The rtabnetsp package requests data from TabNet servers on the São Paulo State Department of Health website, retrieving and preprocessing the data for user manipulation. This article presents the rtabnetsp package and its functions, installation and use; as well as providing examples of its functionalities, which involve listing and searching among available indicators, selecting desired content and obtaining data aggregated according to regionalization level held on the data matrix, enabling greater agility in tasks regarding public health management in the state of São Paulo.
