| The epidemiology and clinical findings of scorpion stings in Sanliurfa region of Turkey, from May to September 2003, were evaluated in this study. Mesobuthus eupeus (M. eupeus) plays a role on 25.8% of the scorpionism cases. This study also showed that intoxications caused by M. eupeus in the southeast of Anatolia region were seen in hot months of the summer, especially on July. Females and people above 15 years old were mostly affected and stung on extremities. Intense pain in the affected area was observed in 98.7% cases, hyperemia in 88.8%, swelling in 54.6%, burning in 19.7%, while numbness and itching were seen less frequently. In our study, the six most frequently observed symptoms were local pain, hyperemia, swelling, burning, dry mouth, thirst,... |

| Fasciolosis is a disease that affects the liver parenchyma and bile ducts of numerous animals, including humans, which causes economic losses and threatens public health. The present work aimed at reporting the distribution and factors connected with Fasciola hepatica infection in cattle in ten municipalities in southern Espírito Santo, Brazil, between 2008 and 2009. During this period, 50 rural properties in ten cities were analyzed and fecal samples from 10% of the cattle on each farm were collected. Of the 717 samples analyzed, 154 (21.33%) presented Fasciola hepatica eggs. As for the 50 rural properties studied, 32 (64%) had animals positive for fasciolosis. Throughout the evaluation, it was observed that 42 (84%) rural properties had flooded areas, 33... |

| 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... |

| Injuries caused by venomous snakes are considered a problem of public health in Brazil, and further studies for a better knowledge are very important. The aim of this work is to describe clinical and epidemiological characteristics that were observed from 1995 to 2000 in the Hospital for Tropical Diseases of Araguaína, Tocantins State, Brazil, which is a unit of health that takes care of patients suffering from tropical diseases. We studied 440 individuals and the most common characteristics observed were masculine sex, age among 15-45 years, bite in low members, and injuries caused by snakes of the Bothrops genus. The signs and symptoms more frequently observed were edema, pain, erythema, and bleeding. The most observed systemic manifestation was... |

| Rabies is a viral zoonotic infectious disease that affects mammals and is caused by genotypes/species of the Lyssavirus genus (Rhabdoviridae, Mononegavirales), with the genotype 1 (classic rabies virus - RABV) being the most prevalent. Despite continuous efforts, rabies is still an incurable disease that causes thousands of deaths amongst humans worldwide. Due to a wide range of hosts and the different evolutionary paths of RABV in each host, several host-specific variants have arisen in an ongoing process. The result of RABV replication in nervous tissues may lead to two opposite clinical outcomes, i.e., paralytic/dumb form and encephalitic/furious one. The paralytic form creates dead-end hosts mainly amongst herbivores, while the furious form of the... |

| Being distant from Brazil's great natural diversity, from its long tradition in the study of snakebites and from the fact that it is one of the few countries which has a national information system for monitoring incidents involving venomous animals, non-Brazilian researchers face risks when estimating the incidence of these accidents in the country. The present work offers a critical review of the main estimates undertaken since 1954. It is interesting to note contradictions between textual and graphic information within the same article, variations over time in the work of a same researcher and differences among distinct authors, and that all these issues remain unmentioned or undiscussed. Comparison among such estimates and the data available at the... |

| Mucormycosis usually presents as a progressive infection with significant angio-invasion. Mucormycosis due to Mucor irregularis (formerly Rhizomucor variabilis var. variabilis), however, is exceptional in causing chronic cutaneous infection in immunocompetent humans, ultimately leading to severe morbidity if left untreated. More than 90 % of the cases known to date were reported from Asia, mainly from China. The nearest neighbour of M. irregularis is the saprobic species M. hiemalis. The aim of this study was to evaluate the taxonomic position, epidemiology, and intra- and inter-species diversity of M. irregularis based on 21 strains (clinical n = 17) by multilocus analysis using ITS, LSU, RPB1 and RPB2 genes, compared to results of cluster analysis with... |

| Pathology to vertebrate hosts has emerged repeatedly in the order Ophiostomatales. Occasional infections have been observed in Sporothrix mexicana at a low level of virulence, while the main pathogenic species cluster in a derived clade around S. schenckii s.str. In this paper, phylogeny and epidemiology of the members of this clade were investigated for 99 clinical and 36 environmental strains using four genetic loci, viz. rDNA ITS and partial CAL, TEF1, and TEF3; data are compared with amplified fragment length polymorphism (AFLP) genotyping. The four main species of the pathogenic clade were recognised. The species proved to show high degrees of endemicity, which enabled interpretation of literature data where live material or genetic information is... |

| In order to determine the risk of transmission of Trypanosoma cruzi by triatomines in Metztitlan municipality, Hidalgo State, Mexico, entomological indexes were calculated and the characteristics of dwellings were described. A transversal, retrospective, descriptive, and observational study was performed by means of an intentional not probabilistic and expertise sampling from January to December of 2005 in 10 localities in which presence of triatomines were investigated either intra or peridomestic environmental in 699 houses. Building material and presence of infected triatomines with T. cruzi were registered to determine entomologic indexes. The triatomine species collected were: Triatoma barberi (Usinger) and T. mexicana (Herrich-Schaeffer) (Hemiptera:... |

| This was a retrospective cohort study using data from the insurance scheme provided by the Japanese Mutual Aid Association (NOSAI). The population of interest comprised all cattle born on NOSAI-client farms in the Japanese prefecture of Hokkaido, Japan for the period 1 April 2005-31 March 2009. The outcome of interest was whether or not at least one calf was stillborn, had died during delivery or died during the first 24 hours of life for a given calving event, termed first 24h mortality risk. A mixed-effects logistic regression model was developed to identify explanatory variables associated with first 24h mortality risk. The final data set comprised details of 1,281,737 calving events on a total of 5172 dairy herds from 19 NOSAI branches located... |

| A molecular epidemiological survey on Theileria orientalis was conducted in a cattle population of Fujian province in China. The screening polymerase chain reaction assay showed that 23 (45%) of 51 blood samples were positive for T. orientalis. DNA sequencing of the major piroplasm surface antigen-encoding gene indicated the presence of 3 different genotypes in the study area(types 1，2，and 5) and identified T. orientalis types 1 and 2 as the major genotypes in the sample population. Because type 2 (Ikeda type in Japan) has been recognized as a relatively virulent genotype of T. orientalis，control and preventive measures to minimize the incidence of infectious diseases among cattle bred in China are necessary. |

| Hemoprotozoan infections often cause serious production losses in livestock. In the present study, we conducted a PCR-based survey of Babesia bovis, Babesia bigemina, Theileria annulata, Theileria orientalis, Trypanosoma evansi and Trypanosoma theileri, using 423 DNA samples extracted from blood samples of cattle (n=202), water buffaloes (n=43), sheep (n=51) and goats (n=127) bred in the Hue and Hanoi provinces of Vietnam. With the exception of T. annulata and T. evansi, all other parasite species (B. bovis, B. bigemina, T. orientalis and T. theileri) were detected in the cattle populations with B. bovis being the most common among them. Additionally, four water buffaloes and a single goat were infected with B. bovis and B. bigemina, respectively. The Hue... |

| Babesia ovata, which is transmitted by Haemaphysalis longicornis, is an intraerythrocytic protozoan parasite of cattle. Based on its morphology, B. ovata is classified as a large-type Babesia. The developmental stages of B. ovata have been described both in cattle and the tick vector. In infected adult female ticks, the parasite is transovarially transmitted to the tick eggs. The sexual reproduction of B. ovata has been demonstrated in the tick midgut. The diagnostic tools that are currently available for the specific detection of B. ovata in cattle include microscopy and polymerase chain reaction assays. The development of improved molecular and serological diagnostic tools has been constrained by the limited availability of genetic data. B. ovata has... |

| A PCR-based survey of hemoprotozoa parasites detected Babesia bigemina, Theileria orientalis and Trypanosoma theileri among cattle and water buffalo in Vietnam, and a new Babesia sp. closely related to Babesia ovata was detected in cattle only. In addition, Theileria annulata and Trypanosoma evansi were not detected in both cattle and water buffalo. Phylogenetic analysis detected T. orientalis MPSP genotypes 3, 5, 7 and N3 in cattle and 5, 7, N1 and N2 in water buffalo. Additionally, water buffalo-derived T. theileri CATL sequences clustered together with a previously reported cattle-derived sequence from Vietnam. This is the first report of a new Babesia sp. in cattle, and T. orientalis MPSP genotype 7 and T. theileri in water buffalo in Vietnam. |

| DNA from ticks recovered from 1137 dogs and 133 cats from Ell over Japan were examined for Rickettsia infection by citrate synthase gene (gltA)-based PCR and partial nucleotide sequencing. A total of 91 dog tick samples and 18 cat tick samples showed a single band of the appropriate size in the nested PCR. Sequence analysis was successfully performed on 102 samples. DNA of Rickettsia japonica or closely related Rickettsia spp. strains were detected from 38 licks in 16 prefectures mainly in western Japan. The other 33, detected from 13 prefectures including Hokkaido and Okinawa, were found to be Rickettsia helvetica or closely related strains. A total of 29 DNA that showed highest homology with Rickettsia akari or closely related strains were detected in 19... |
