Efficient Identification of HIV Serodiscordant Couples by Existing HIV Testing Programs in South Brazil.

ObjectiveTo examine the feasibility of identifying HIV negative at risk individuals in HIV serodiscordant couples, during voluntary HIV testing in South Brazil.MethodsWe surveyed HIV testers at 4 public testing sites in Rio Grande do Sul. We obtained information on risk behaviors and sexual partnerships. HIV testing and testing for recent infection were performed; HIV prevalence and risk behaviors were assessed among subjects who reported having a steady partner who was HIV positive (serodiscordant group) and compared with the general testing population.ResultsAmong 3100 patients, 490 (15.8%) reported being in a steady relationship with an HIV positive partner. New HIV infections were diagnosed in 23% of the serodiscordant group (vs. 13% in the general population, p = 0.01); among newly positive subjects, recent HIV infections were more frequent (23/86, 26.7%) among testers with positive partners than among the general testing group (52/334; 15.6%; p = 0.016). Less than half of the serodiscordant testers reported having used a condom during the last sexual intercourse with their HIV-positive partner. Participants with inconsistent condom use with steady partner were four times more likely to test positive for HIV compared to those who reported always using condoms with the steady partner (OR: 4.2; 95% CI: 2.3 to 7.5).ConclusionIt is highly feasible to identify large numbers of HIV susceptible individuals who are in HIV serodiscordant relationships in South Brazil testing sites. Condom use within HIV serodiscordant couples is low in this setting, suggesting urgent need for biomedical prevention strategies to reduce HIV transmission

Identification of Salmonella clonal groups and enterobacteria quantification in different risk areas of manufacturing process in four Brazilian feed mills

Identification of critical points for contamination of feed and spread of Salmonella may contribute to the development of control plans. A cross-sectional study was conducted to identify Salmonella clonal groups in feed mill facilities. A total of 1,322 samples were collected in four swine feed manufacturing facilities. Samples were taken from ingredients and from dust deposited on the floor and on the inner surface of storage bins, bucket elevators, mills, mixers, scales, pelleting chamber and cooler

Detection of salmonella heidelberg resistant to colistin in the intestinal content of pigs at slaughter.

Abstract : Salmonella Heidelberg has increasingly been reported as cause of human salmonellosis worldwide. In Brazil, S. Heidelberg has been reported in poultry but it is infrequently isolated from pigs. Here, we describe the isolation of S. Heidelberg resistant to colistin from slaughter pigs. Five pigs and their carcasses belonging to a same slaughter batch in ten consecutive days were sampled for fragment of intestine in the ileocecal region and sponges rubbed on the carcass surface (400 cm2 ) before chilling. Salmonella detection was performed according to the ISO 6579:2002. Intestinal content was also subjected to Salmonella enumeration by a miniaturized Most Probable Number (MPN) protocol. Salmonella isolates were characterized by antimicrobial resistance by the disk diffusion test, the minimum inhibitory concentration to colistin determination and to gene mcr-1 investigation by PCR. Salmonella was isolated from the intestinal content of 64% (32/50) of the pigs, in amounts that varied from 2.7 to >1,400 MPN/g. Salmonella Heidelberg was the most frequent serovar identified in the intestinal content samples (20/50; 40%), and this serovar was present in eight of the ten pig batches sampled. At the prechill, Salmonella was isolated from 8% of carcasses, and S. Heidelberg was not detected. Salmonella Heidelberg strains were resistant against ampicillin (n=9), tetracycline (n=8), sulfonamide (n=8) and gentamicin (n=5). Nine multi-drug resistant strains were detected; among them four strains were positive for the gene mcr-1. In these strains the MIC value was 8 µg.mL-1 , while in the strains without the mcr-1 gene it ranged from 2 µg.mL-1 to 4 µg.mL-1 . Therefore, humans in contact with carrier pigs or their environment may be exposed to S. Heidelberg, including strains harboring the gene mcr-1.SafePork 2017

Quantificação de Salmonella sp. em fezes suínas por PCR em tempo real.

Salmonellasp. é uma bactéria capaz de colonizar o trato gastro-intestinal dos seres humanos e animais. O suíno é uma importante fonte de infecção, pois elimina a bactéria de forma intermitente nas fezes contaminando o ambiente de criação e abate. Além disso, alguns animais podem excretarquantidades maiores desta bactéria, sendo considerados super-excretores. Desta forma, são necessárias técnicas de quantificação bacteriana para a identificação desses animais. Entre estas técnicas de PCR em tempo real se destaca devido sensibilidade e rapidez nos resultados. O objetivo deste trabalho foi o desenvolvimento de uma curva de quantificação de Salmonella sp. em fezes de suínos. Para tanto, fezes suínas foram contaminadas com inóculo de Salmonella sp. em diluições seriadas e incubadas em água peptonada tamponada por seis horas. Alíquotas de 1 mL foram retiradas para extração do DNA que foi padronizado a 10 ng/μL. A reação de qPCR foi realizada utilizando-se o sistema SYBR Green, com alvo no gene Hill A. A contagem na diluição 10-5 foi 1,1 x 103 UFC/mL seguida de 14,33 x 101UFC/mL e 2,67 x 101UFC/mL para as diluições 10-4e 10-3respectivamente. As médias dos CT obtidos nas 10 repetições variaram de 15,54 a 32,10. Os resultados das contagens foram associados aos respectivos CTe foi possível obter uma curva de quantificação de Salmonellaque poderá ser aplicada a identificação de suínos excretores
