| In the village of Cavunge, located in a dry tropical, semiarid rural region of the state of Bahia, Brazil, a sentinel study on viral hepatitis is underway. We report on the first part of the study. The objective of this study was to determine the prevalence of serological markers for hepatitis A, B and C in the village. Cross sectional study. Blood samples were tested for serological markers of hepatitis A (HAV), B (HBV) and C (HCV) through ELISA-III assay. In HBsAg and anti-HCV carriers, HCV-RNA and HBV-DNA were checked by PCR. The prevalence of anti-HAV IgG was 83.3% (1,210/1,452), being higher among residents from the village (87.4%) than in residents from the rural area (79.5%); it also higher among individuals older than 10 years of age.

| This investigation evaluated the epidemiological aspects of scorpion stings in different areas of Saudi Arabia. A total of 72,168 cases of scorpion stings recorded in Ministry of Health Medical Centers in 11 selected areas of Saudi Arabia were analyzed based on area, age, sex, time of sting, sting site, treatment outcome, time of year, and scorpion species. Stings occurred throughout the year; the highest frequency was in June (15.08%), the lowest in February (2.52%). Most patients were male (61.8%); the majority of which were more than 15 years old (65.4%). Nocturnal envenomation (47.74%) was more common than diurnal (43.91%); most stings were in exposed limbs (90.95%), mainly in the lower limbs (63%). Most envenomings were mild (74.48%) and all evolved... |

| Neurocysticercosis (NCC) is a common parasitic disease in our region, presenting diversity of neurological symptoms and signs. The present study has as primary objective an evaluation of the NCC's clinical and epidemiological profile within Bahia State, by means of a prospective study of 220 patients diagnosed from March 1988 to March 1999, with a follow-up of six months. Exams, such as Computed Cranial Tomography Scan (CT), Cerebral Spine Fluid (CSF) and Electroencephalogram (EEG), were accomplished in three distinct moments of these patients' evolution: at starting or diagnostic point (zero time), at after-intervention period (one month after treatment), and at control period (six months after treatment). |

| After a general presentation of the Thau lagoon together with its geographic location, socio-economic activities linked to shellfish culture and fishing, this paper investigates the health conditions of the shellfish harvesting areas. I he influence of heavy rainfall following a prolonged drought period is underlined as a determining factor of the momentary bacterial pollution in the harvesting areas, leading to a suspension of sales based on analyses relying solely on the detection of faecal coliforms. As of 1989, bacteriological monitoring was reorganized in the form of a data collection network taking into consideration environmental assessments of water quality as well as shellfish hygiene in order to protect consumer health. Its extension to the... |

| Shigella spp., the human pathogen responsible for shigellosis, is highly infectious even at low levels. The incidence rate of shigellosis varies with geographical distribution, location human development index, and age groups, being higher among children aged under 5 years. In Brazil, a few works indicate that shigellosis cases are underestimated, with S. flexneri and S. sonnei strains being the major agents responsible for the shigellosis cases. The present study used pulsed field gel electrophoresis (PFGE) to investigate the molecular epidemiology of 119 strains of S. sonnei and S. flexneri isolated from shigellosis cases that occurred in the metropolitan areas of Ribeirão Preto and Campinas Cities, São Paulo Sate, southeast Brazil. The results indicated... |

| ABSTRACT: Brown rot is the most important disease of peaches in Brazil. The objective of this study was to compare the brown rot monocyclic components from Monilinia fructicola and M. laxa isolates from Brazil on peaches, due to the detection of M. laxa in the São Paulo production area. Conidia germination and pathogen sporulation were assessed in vitro under a temperature range of 5-35oC and wetness duration of 6-48h. Incubation and latent periods, disease incidence, disease severity and pathogen reproduction on peach fruit were evaluated under 10, 15, 20, 25 and 30oC and wetness duration of 6, 12 and 24h. Six of seven parameters of a generalised beta function fitted to conidia germination of M. fructicola and M. laxa were similar. Only the shape... |

| ABSTRACT Human T-lymphotropic viruses (HTLV) are Deltaretroviruses that infect millions of individuals worldwide via the same transmission routes as HIV. With the aim of exposing the possible re-emergence of HTLV in West Africa since discovery, a systematic review was carried out, focusing on the distribution of the virus types and significance of frequent indeterminate reports, while highlighting the need for mandatory routine blood screening. Capturing relevant data from discovery till date, sources searched were Google Scholar, CrossRef, NCBI (PubMed), MEDLINE, Research Gate, Mendeley, abstracts of Conferences and Proceedings, organization websites and reference lists of selected papers. A total of 2626 references were initially retrieved using search... |

| Botrytis blight caused by Botrytis cinerea is an important disease of rose (Rosa hybrida) grown in greenhouses in Brazil. As little is known regarding the disease epidemiology under greenhouse conditions, pathogen survival in crop debris and as sclerotia was evaluated. Polyethylene bags with petals, leaves, or stem sections artificially infected with B. cinerea were mixed with crop debris in rose beds, in a commercial plastic greenhouse. High percentage of plant parts with sporulation was detected until 60 days, then sporulation decreased on petals after 120 days, and sharply decreased on stems or leaves after 90 days. Sporulation on petals continued for 360 days, but was not observed on stems after 150 days or leaves after 240 days. Although the fungus... |

| The present work aims to find the epidemiological profile of snakebites in Morocco through a retrospective study of 1,423 snakebite cases that occurred between 1992 and 2007. Data were obtained from medical charts of envenomation at the Poison Control and Pharmacovigilance Center of Morocco. Results revealed that 86% of the snakebites had occurred in rural areas and that males were significantly more affected than females at a sex ratio of 23:20. Furthermore, 35% of the bites happened during the summer, with a peak of 215 cases in June (15.1%). We also discovered that 67.3% of the patients were bitten during the day. The age group that comprised the most agriculturally active persons, from 20 to 44 years old, was the most affected by snakebites (551... |
