1. In vitro degradative effect of purified zearalenone with or without adsorbents after bionic digestion
Abstract The occurrence of zearalenone is considered a major risk factor affecting human and animal health worldwide. Zearalenone-contaminated feed can cause serious disorders and diseases in farm animals. A number of approaches have been developed to counteract zearalenone, but only few can be used. A potential approach to protecting animals against the har

3. Detection of potentially pathogenic bacteria on cell phones of hospital and university-based populations in Curitiba, southern Brazil. A cross-sectional study
ABSTRACT BACKGROUND: Cell phones have become indispensable for professional activities, including healthcare. Thus, they are possible sources of bacterial contamination. There is a scarcity of data in the literature regarding identification of risk factors for contamination of cell phones with pathogenic bacteria. OBJECTIVE: To compare the prevalence rat

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. Salmonella Enteritidis in Layer Farms of Different Sizes Located in Northern China: On-Farm Sampling and Detection by the PCR Method
ABSTRACT Salmonella enterica subspecies enterica serotype Enteritidis (SE) has caused foodborne infections over decades. It is transmitted mainly from contaminated eggs to humans. SE is commonly present in layer houses, and closely interacts with environmental factors. The objective of the present study was to develop a viable PCR method to identify SE in en

7. Milk quality parameters associated with the occurrence of veterinary drug residues in bulk tank milk
ABSTRACT Veterinary drug residues in bulk tank milk are important to all sectors of the dairy chain because they are one of the major factors which determine the safety of the final product. This study attempted to identify milk quality parameters that are associated with the occurrence of veterinary drug residues using multivariate principal component analy

8. Application of post-discharge region of atmospheric pressure argon and air plasma jet in the contamination control of Candida albicans biofilms
Introduction:Candida species are responsible for about 80% of hospital fungal infections. Non-thermal plasmas operated at atmospheric pressure are increasingly used as an alternative to existing antimicrobial strategy. This work investigates the action of post-discharge region of a non-thermal atmospheric plasma jet, generated by a gliding arc reactor, on bi

9. A new improved protocol for in vitro intratubular dentinal bacterial contamination for antimicrobial endodontic tests: standardization and validation by confocal laser scanning microscopy
Objectives To compare three methods of intratubular contamination that simulate endodontic infections using confocal laser scanning microscopy (CLSM). Material and Methods Two pre-existing models of dentinal contamination were used to induce intratubular infection (groups A and B). These methods were modified in an attempt to improve the model (group C).

10. Experimental infection of BHK21 and Vero cell lines with different Mycoplasma spp.
Mycoplasma spp, belongs to the class Mollicutes and is capable to produce alterations in cellular cultures causing damages to the biotechnological industry. Bioproducts generally require two essential inputs, bovine serum and cells. The study herein aims to evaluate the mycoplasma concentrations that affect the growing of BHK21 and Vero cells. The species us

11. Ability of a Lactobacillus rhamnosus strain cultured in milk whey based medium to bind aflatoxin B1
This study aimed to compare Lactobacillus rhamnosus growth in MRS (de Man, Rogosa and Sharpe) broth and a culture medium containing milk whey (MMW) and to evaluate aflatoxin B1 (AFB1) adsorption capacity by bacterial cells produced in both culture media. L. rhamnosus cells were cultivated in MRS broth and MMW (37 °C, 24 hours), and bacterial cell concentrat

12. EFEITO TOXICOGENÉTICO DO POLIMORFISMO ALA16VAL DO GENE MnSOD EM LEUCÓCITOS EXPOSTOS IN VITRO AO METIL MERCÚRIO / TOXIGENETIC EFFECT OF ALA16VAL MnSOD GENE POLYMORPHISM ON LEUCOCYTES IN VITRO EXPOSED TO METHYL MERCURY
The environmental contamination by methyl mercury (MeHg) is a great health public problem in some world regions like Amazonia. The MeHg toxic effects seem to be influenced by environmental and genetic factors. However, there are few studies evaluating the genetic influence on MeHg toxicity in humans. Therefore, the aim of this present study was to evaluate t
