1. Low frequency of antibodies anti-Neospora caninum in rodents in Fernando de Noronha Island, Brazil
Abstract This study aimed to evaluate the frequency of Neospora caninum antibodies in rodents from the Island of Fernando de Noronha, Brazil, and to contribute to epidemiological data on neosporosis in this region. Blood samples were collected from 154 black-rats (Rattus rattus) and 12 rock-cavies (Kerodon rupestris). The search for anti-N. caninum antibodie

2. Implantação de protocolo de vigilância e atenção à saúde de ex-trabalhadores e população exposta a chumbo, cádmio, cobre e zinco em Santo Amaro, Bahia
Resumo Introdução: ao longo de 40 anos, estudos evidenciam a contaminação da cidade de Santo Amaro por elevados níveis de chumbo e outros metais. Estudos epidemiológicos revelaram altas concentrações de chumbo e cádmio em amostras de sangue de pescadores, trabalhadores e em compartimentos ambientais. Em 2010, foi instituído um protocolo para orie

3. Turn down - turn up: a simple and low-cost protocol for preparing platelet-rich plasma
OBJECTIVE: To describe and analyze a new protocol for the extraction of platelet-rich plasma (PRP) for use in clinical practice and compare this technique with methods that have been previously described in the medical literature. METHODS: We extracted PRP from 20 volunteers using four different protocols (single spin at 1600 ×g, single spin at 600 ×g, d

4. Effects of fed mycotoxin contaminated diets supplemented with spray-dried porcine plasma on cholinergic response and behavior in piglets
Abstract: The aim of this study was to evaluate the effect of spray-dried porcine plasma (SDPP) supplementation on cholinesterase enzymes and its relationship with animal behavior of weaning piglets exposed to mycotoxin contaminated diets. To achieve these objectives, two experimental design approaches were used. Male piglets (7.15±0.61kg) were allocated in

5. Detection and clearance of a mosquito densovirus contaminant from laboratory stocks of Zika virus
BACKGROUND The Zika virus (ZIKV) epidemics that affected South America in 2016 raised several research questions and prompted an increase in studies in the field. The transient and low viraemia observed in the course of ZIKV infection is a challenge for viral isolation from patient serum, which leads to many laboratories around the world sharing viral stra

6. EFICIÊNCIA DE DIFERENTES PROTOCOLOS PARA ISOLAMENTO DE Campylobacter jejuni DE CARNE DE FRANGO
Resumo Campylobacter jejuni é o principal causador de gastroenterite bacteriana aguda e a carne de frango é um importante veículo do agente. Entretanto, as metodologias convencionais de isolamento de Campylobacter muitas vezes não são eficientes, podendo levar a resultados errôneos. Sendo assim, este trabalho teve como objetivo avaliar diferentes méto

7. Retrospective evaluation of the clinical characteristics associated with Corynebacterium species bacteremia
ABSTRACT Objectives: Corynebacterium spp. are becoming recognized as pathogens that potentially cause various infections. We aimed to evaluate the clinical characteristics associated with Corynebacterium spp. bacteremia. Patients and methods: We retrospectively reviewed the medical records of all adult patients who had positive blood cultures for Corynebac

8. Antimicrobial susceptibility profile and research of mec A and erm genes in coagulase-negative staphylococci isolated from platelet concentrates bags
Abstract In recent years, several studies have described the clinical impact of bacterial infection associated with transfusion of platelet concentrates (PCs). Among the blood components, PCs are responsible for the highest rates of bacterial contamination as well as septic transfusion reactions. We assessed antimicrobial susceptibility profile, resistance t

9. FREQUENCY OF ANTI- Toxocara spp. ANTIBODIES IN INDIVIDUALS ATTENDED BY THE CENTRO DE SALUD FAMILIAR AND ENVIRONMENTAL CONTAMINATION WITH Toxocara canis EGGS IN DOG FECES, IN THE COASTAL NIEBLA TOWN, CHILE
SUMMARY The frequency of anti-Toxocara spp. antibodies in individuals attended by the Centro de Salud Familiar in the coastal Niebla town, Chile, was related to the host and to environmental factors. IgG anti- Toxocara antibodies were detected with a commercial ELISA kit (SCIMEDX Corporation, USA). Samples with undetermined absorbance values were subjected t

10. Contamination index. A novel parameter for metal and pesticide analyses in maternal blood and umbilical cord
ABSTRACT PURPOSE: To evaluate the contamination index of metals and pesticides in pregnant women, and to relate this to perinatal outcomes. METHODS: Descriptive, retrospective, exploratory study, developed from existing secondary data analyses at Level III maternity center. A total of 40 mothers with their newborns (NB), living in a rural area in Botucat

11. INVESTIGATION OF BIOFILM FORMATION IN COAGULASE-NEGATIVE STAPHYLOCOCCI ISOLATED FROM PLATELET CONCENTRATE BAGS
Platelet Concentrates (PCs) are the blood components with the highest rate of bacterial contamination, and coagulase-negative staphylococci (CoNS) are the most frequently isolated contaminants. This study investigated the biofilm formation of 16 contaminated units out of 691 PCs tested by phenotypic and genotypic methods. Adhesion in Borosilicate Tube (ABT)

12. Single-tube nested PCR assay with in-house DNA extraction for Mycobacterium tuberculosis detection in blood and urine
Abstract: INTRODUCTION : Molecular analyses are auxiliary tools for detecting Koch's bacilli in clinical specimens from patients with suspected tuberculosis (TB). However, there are still no efficient diagnostic tests that combine high sensitivity and specificity and yield rapid results in the detection of TB. This study evaluated single-tube nested polymer
