| ABSTRACT A helminthological examination was carried out on 14 specimens of Eucinostomus melanopterus (flagfin mojarra) and 19 Eugerres plumieri (striped mojarra), of which a total of 461 helminths were collected. As a result, and 12 taxa were registered (five species, five genus and tow family), as follows: four monogeneans, five digeneans (four adults, one metacercaria), one cestode (larva) and tow nematodes (larvae). The highest prevalence was for Neodiplectanum mexicanum (29 %) infecting E. melanopterus and Aristocleidus hastatus (37 %) infecting E. plumieri. Both hosts shared 50 % of recorded species, and none of the identified helminthes represents a zoonotic risk. |

| The present study describes Camallanus maculatus n. sp. (Nematoda: Camallanidae) from Xiphophorus maculatus (Osteichthyes: Poecilidae) collected in an ornamental fish farm in São Paulo State, Brazil. Thirty-three out of 40 examined fish were parasitized (82% prevalence) with mean intensity of 2.8 (1-20). Male specimens were 3,500µm total length and females 7,100µm total length, provided with orange-brown buccal capsule and two developed tridents. Males showed two unequal spicules, gubernaculum absent and females with vulva situated in the middle of the body. The main characteristics were the sleekly longitudinal ridges in the buccal capsule in both sexes, enlargement at the anterior end of the smaller spicule, the number of genital papillae, longer... |

| ABSTRACT Prevalence of bovine tuberculosis infection in cattle in Aksu Prefecture determined by intradermal tuberculin skin test (TST), between 1985 and 2016. Cattle were analyzed according to region, feeding pattern, herds and age. A total of 890,009 cattle were tested, with overall bovine tuberculosis prevalence of 0.13% (1172/890009). Statistically significant difference was found in feeding pattern and herds. Prevalence in cows (0.19%, 615/327022) was higher than that in beeves (P< 0.01, OR= 1.903, 95% CI = 1.696 to 2.134). Significant difference (P< 0.01; OR= 2.238, 95%; CI= 1.937 to 2.585) was evident for rates for bovine tuberculosis in the peasant household (0.12%, 942/802343) and farm groups (0.26%, 230/87666). The overall prevalence of bTB... |

| The prevalence of caprine arthritis-encephalitis (CAE) infection in dairy goat herds from Rio Grande do Norte State, Brazil, was estimated, and the predisposing factors to the infection were identified. An epidemiologic survey was held to collect information on educational level of the owner and origin of the animals, and on sanitation and vaccination practices, diseases, morbidity and mortality rates in the herds. The prevalence of CAE virus infection was 11%, and CAE was always observed in some goats in all studied municipalities. |

| ABSTRACT The present study investigated the seroprevalance of Visna Maedi Virus (VMV) and Border Disease Virus (BDV) infections in sheeps in regions in and around Van province, Turkey. Sample materials were taken from 360 sheep sent to slaughterhouses around Van. All serum samples were examined using ELISA for antibodies for Visna Maedi (VMV) and Border Disease (BDV) viruses. Of these, 38 (10.5%) tested positive for Visna Maedi virus antibodies and 163 (45.2%) for Border Disease virus antibodies. Varying numbers of samples were positive for both virus antibodies across the towns of Erciş, Çaldıran, Erçek and Başkale in Van, Ağrı and Hakkari provinces. Both infections should be eliminated by informing veterinarians and animal owners, identifying and... |

| RESUMO Angiostrongylus cantonensis e Angiostrongylus costaricensis são nematoides parasitas que residem em roedores e usam gastrópodes como hospedeiros intermediários. Achatina fulica, conhecida como caramujo-gigante-africano, é um hospedeiro intermediário que desempenha importante papel na dispersão de A. cantonensis e A. costaricensis, patógenos zoonóticos que causam, respectivamente, meningoencefalite eosinofílica e angiostrongilíase abdominal em humanos. O objetivo deste estudo foi o de coletar caramujos (A. fulica, n=90) de oito regiões diferentes (Rudge Ramos, Baeta Neves, Planalto, Demarchi, Dos Alvarengas, Batistini, Montanhão, Rio Grande) da cidade de São Bernardo do Campo (SP) para detecção molecular de A. cantonensis ou A. costaricensis pela... |

| The goal of this study was to determine the prevalence of Hepatozoon spp. infection in recently captured snakes from Botucatu, São Paulo State, Brazil. Blood was collected from all snakes by ventral tail venipuncture. Blood smears were air dried, fixed with methanol, and stained with 10% Giemsa solution. The slides were microscopically examined for detection of hemoparasites by light microscopy at 250x magnification. A total of 238 snakes from 23 species were examined, of which 135 (56.7%) were venomous and 103 (43.3%) non-venomous snakes. The more numerous venomous species sampled were Crotalus durissus terrificus (n=108) and Bothrops jararaca (n=17) and non-venomous snakes were Oxyrhopus guibei (n=35), Boa constrictor amarali (n=18), and Waglerophis... |

| The aim of this work was to study the estrogen receptor alpha (ERS1) PvuII and XbaI gene polymorphisms prevalence in randomly selected women population from Rio de Janeiro and Espírito Santo states in Brazil by polymerase chain reaction restriction fragment lengths polymorphism (PCR_RFLP) methodology. It was shown that Rio de Janeiro women exhibited a significantly different prevalence of XbaI polymorphism comparing to Espirito Santo women. Nonetheless, similar prevalence of PvuII polymorphism was found in both women´s populations. Moreover, a strong linkage disequilibrium was observed between these SNPs reinforcing the hypothesis of differential pattern of inheritance observed on such populations. |

| We investigated the prevalence and the risk factors for infection with Helicobacter pylori in a randomly-selected population of adults from a low-income community in Northeastern Brazil. Helicobacter pylori infection was determined by ELISA. Risk factors were assessed using a structured interview. Two hundred and four individuals were included in the study, including 49 males and 155 females, ranging from 18 to 80 years old. Overall, 165 of 204 participants (80%) were H. pylori positive, without significant gender differences (p= 0.49). The infection rate was of 84.7% in subjects 18 to 30 years of age, increasing to 92% in subjects 46-60 years old. Above 60 years old, the prevalence decreased slightly. As a whole, the prevalence of infection did not... |

| BACKGROUND: Patients with chronic liver disease have a higher risk of fulminant hepatitis when infected with hepatitis A virus, and vaccination of these patients against such infection is recommended. In Brazil, mainly in the South and Southeast regions, the epidemiology of hepatitis A (HA) has shifted from high to intermediate endemicity, which would have implication on policy of HA vaccination for these populations. OBJECTIVE: To verify the prevalence of HA immunity in adult patients with liver cirrhosis (LC), in Uberlândia MG, a city of Southeastern Brazil. METHODS: Between December 2005 and December 2006, 106 patients with LC were consecutively evaluated. In addition, 75 individuals without LC or alcoholism were evaluated (control group - CG). RESULTS:... |

| Abstract To assess the prevalence of hepatitis C virus infection among men who have sex with men (MSM) in Central Brazil, a cross-sectional study was conducted in the City of Goiânia, Central Brazil, using Respondent-Driven Sampling (RDS). All serum samples were tested for anti-HCV and also for alanine aminotransferase (ALT). Anti-HCV positive samples and/or those with elevated ALT were tested for HCV RNA and genotyped. Of the 522 participants, four were found to be anti-HCV positive, and one was also HCV RNA positive (active HCV infection). Elevated ALT was found in 14 individuals. Of these, one showed evidence of acute HCV infection (HCV RNA positive and anti-HCV negative). Therefore, five MSM were positive for either anti-HCV and/or HCV RNA, giving a... |
