Scientific Opinion on an update on the present knowledge on the occurrence and control of foodborne viruses
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
A review of the biology, epidemiology, diagnosis and public health importance of foodborne viruses was performed. Data needs to support a risk assessment were also identified. In addition possible control options and their anticipated impact to prevent or reduce the number of foodborne viral human infections were identified, including the scientific reasons for and against the establishment of food safety criteria and process hygiene criteria for viruses for certain food categories. Food may be contaminated by virus during all stages of the food supply chain, and transmission can occur by consumption of food contaminated during the production process (primary production, or during further processing), or contaminated by infected food handlers. Transmission...

Potential ways to address the issues that relate to the techniques for analyzing food and environmental samples for the presence of enteric viruses are discussed. It is not the authors' remit to produce or recommend standard or reference methods but to address specific issues in the analytical procedures. Foods of primary importance are bivalve molluscs, particularly, oysters, clams, and mussels; salad crops such as lettuce, green onions and other greens; and soft fruits such as raspberries and strawberries. All types of water, not only drinking water but also recreational water (fresh, marine, and swimming pool), river water (irrigation water), raw and treated sewage are potential vehicles for virus transmission. Well over 100 different enteric viruses...

Provedor de dados: Revista Brasileira de Ciência Avícola
Autores: Ito,NMK; Miyaji,CI; Lima,EA; Okabayashi,S; Claure,RA; Graça,EO.
Duodenum swabs were harvested from 80 broilers in 15 flocks of 8 broiler farms and were submitted to bacteriological evaluation. Five broiler breeders were sampled to obtain comparative data. Macro and microscopic lesions in the gut and the liver were evaluated in all birds submitted to swab harvesting and also broilers of two slaughter plants. Semiquantitative bacterial examination in duodenum swabs demonstrated higher microorganism growth in blood agar than in MacConkey medium. Staphylococcus sp, Enterococcus sp and Escherichia coli were found in some broiler flocks. An increased cellularity of the muscular mucosae of duodenum villi and/or the presence of some gametocytes or schizonts of coccidia were found in the lesioned gut in addition to high...

Lamivudine for chronic hepatitis B: a brief review
Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Palumbo,Emilio.
Until recently, the only generally approved treatment for chronic hepatitis B was alpha-interferon; however, it gives only moderate efficacy in terms of sustained response (biochemical, virological and histological). In fact, only 20% to 40% of treated patients respond to therapy, with lower percentages (~ 10%) among patients infected with precore-mutant strains of HBV (HBeAb HBV-DNA positive). The FDA of the USA approved the use of lamivudine in adult patients affected by chronic hepatitis B in 1998. In this review, we focused on the pharmacokinetic and pharmacodynamic properties and efficacy and tolerability of lamivudine in the treatment of chronic hepatitis B cases that are both HBeAg and anti-HBe-positive.

How to handle Western blot (WB) seroindeterminate individuals for Human T-lymphotropic Virus 1/2 (HTLV-1/2) constitutes a challenge for blood banks and fam ilies. We made a cross-sectional study of 191 enzyme linked immunoassay (EIA) reactive individuals from the hematological center (HEMOCE) of Fortaleza (Brazil), examining their serological (WB) and molecular (PCR) diagnosis, and demographic profiles, as well as a possible association of their condition with other infectious pathologies and risk factors. Ethical institutional approval and personal consent were obtained. Out of 191 EIA reactive individuals, 118 were WB seroindeterminate and 73 were seropositive for HTLV-1/2. In the PCR analysis of 41 WB seroindeterminate individuals, 9 (22%) were positive...

Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Franca,Rita; Silva,Luciana; Melo,Maria Clotildes; Cavalcante,Suzy; Lima,Bruno; Rocha,Anita; Gomes,Cristiana; Franca,Mônica.
Knowledge about hepatotropic viruses is crucial for pediatricians because of the high prevalence of viral hepatitis during childhood. The multiplicity of hepatotropic viruses, the spectrum of acute and chronic infections, and the sequels of viral hepatitis result in a need for physicians to better understand the clinical and epidemiological context of patients with viral hepatitis, as well as the importance of prevention measures for hepatitis. A descriptive cross-sectional study was made of pediatrician's knowledge about viral hepatitis, through questionnaires to 574 pediatricians, with no obligation of identification. The pediatricians were recruited among those who attended a national Congress of Pediatrics in Brasília, Brazil. Among these...

Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Mourão,Maria Paula Gomes; Lacerda,Marcus Vinícius Guimarães de; Bastos,Michele de Souza; Albuquerque,Bernardino Cláudio de; Alecrim,Wilson Duarte.
Dengue fever is the world's most important viral hemorrhagic fever disease, the most geographically wide-spread of the arthropod-born viruses, and it causes a wide clinical spectrum of disease. We report a case of dengue hemorrhagic fever complicated by acute hepatitis. The initial picture of classical dengue fever was followed by painful liver enlargement, vomiting, hematemesis, epistaxis and diarrhea. Severe liver injury was detected by laboratory investigation, according to a syndromic surveillance protocol, expressed in a self-limiting pattern and the patient had a complete recovery. The serological tests for hepatitis and yellow fever viruses were negative. MAC-ELISA for dengue was positive.
