Prevalence of endoparasites by microscopic analysis in free-range chickens in a Brazilian semiarid region.

The aim of this study was to evaluate the prevalence and diversity of endoparasitic fauna and the risk factors associated with parasite infections in free-range chickens in the state of Paraíba, northeastern Brazil. Ten municipalities were visited and, in each of them, ten farms, to collect animal feces and apply epidemiological questionnaires. Feces from 417 poultry were used to perform EPG (eggs per gram) and OoPG (oocysts per gram) tests.

Prevalence and diversity of spp. in free-range chickens in northeastern Brazil.

In tropical regions, family farming is a form of production and work that is highly present in rural areas. Because the production system for free-range chickens has a low level of technification, it frequently presents massive infection by coccidia. The objective of this study was to determine the prevalence and diversity of species in free-range chickens in northeastern Brazil.

Laboratory diagnosis of mange-causing mites in dogs using a modified centrifugation-flotation technique in sucrose solution.

Among the skin disorders of dogs, scabies is notable for its high occurrence rate and the need for veterinary interventions. There are two obstacles to making this diagnosis through direct investigation under a microscope (DIM): the continual need to make new slides when the results are negative and the long time needed for reading these slides. Thus, the objective of the present study was to compare efficacy between DIM and the technique of centrifugation-flotation in sucrose solution (CFSS) in samples from dogs in the semiarid region of the state of Paraíba, Brazil.

Comparison of Equations to Predict Energy Requirements With Indirect Calorimetry in Hospitalized Patients.

Background: The accuracy of methods to determine resting energy expenditure (REE) contributes toward the adequate provision of nutrition support to hospitalized patients. Indirect calorimetry (IC) is considered the gold-standard method to determine REE. The aim of this study is to evaluate the degree of agreement between the REE measured by IC (REE-IC) and REE estimated by predictive equations in intensive care unit patients.

Diversity of enteric coccidia in pigs from the Paraíba Semiarid Region of Northeastern Brazil.

There is great diversity in swine coccidia, which are responsible for causing intestinal disorders ranging from sporadic diarrhea to severe cases of hemorrhagic enteritis. Thus, determining the species of coccidia that affect the animals of a region and associating them with the characteristics of the farms become extremely important. The objective of this study was to determine the prevalence of coccidia parasites in pigs reared in a family farming production system in the Semiarid Region of the State of Paraíba, Northeast Brazil.

Prevalence and risk factors associated with swine gastrointestinal nematodes and coccidia in the semi-arid region of northeastern Brazil.

In northeastern Brazil, with has a predominantly dry climate, farmers seek alternative sources of income and livelihood by the rearing pigs. The gastrointestinal parasites that affect these animals represent an obstacle in the production and can cause significant economic loss. This study aimed to determine the prevalence and risk factors associated with gastrointestinal nematodes and Coccidia in swine herds in the Sousa microregion, Paraíba state, northeastern Brazil.

The Brazilian Cardioprotective Nutritional Program to reduce events and risk factors in secondary prevention for cardiovascular disease: study protocol (The BALANCE Program Trial).

This article reports the rationale for the Brazilian Cardioprotective Nutritional Program (BALANCE Program) Trial. This pragmatic, multicenter, nationwide, randomized, concealed, controlled trial was designed to investigate the effects of the BALANCE Program in reducing cardiovascular events. The BALANCE Program consists of a prescribed diet guided by nutritional content recommendations from Brazilian national guidelines using a unique nutritional education strategy, which includes suggestions of affordable foods.
