Morphologically, this new species differs from S. niveocremeum and S. suecicum by the small oil drops in the cytoplasm of subicular hyphae and the spore size. An updated key of Sistotremastrum

species is provided.”
“Medically important arthropods, including fleas, play an important role in causing clinical disorders and disease in man and domestic animals. This study was conducted to determine the seasonal flea infestations for domestic dogs from different geographic regions of Iran. A total of 407 fleas, belonging to 5 different species, were recovered from 83 domestic dogs from 3 regions. There was a distinctive pattern Crenolanib of species distribution and infestations with the highest infestation rates observed in a temperate climate and higher rainfall. Additionally, fleas were observed over all seasons, except February and March, with MI-503 the highest infestation rate observed in August (24.7%) and the lowest rate in January (1.7%). They also parasitize dogs with a different spectrum of species. The cat flea, Ctenocephalides felis (67.5%), exhibited the highest prevalence among all flea species found on dogs. Thus, climatic conditions and seasonal

patterns impact on flea infestation and must be considered in developing control programs.”
“Background: The International Panel on Diagnosis of Multiple Sclerosis has proposed new magnetic resonance imaging (MRI) criteria for the diagnosis of multiple

sclerosis (MS) in patients with clinically isolated syndrome (CIS). We aimed to evaluate these new criteria in a cohort of patients from Buenos Aires, Argentina.\n\nMethods: Patients with CIS, in whom MRI was performed within three months of onset of symptoms, were included between January 2005-June 2010. Poser or McDonald 2005 criteria were used as gold standard diagnostic criteria for MS. MRI was assessed by a blind evaluator identifying recently diagnostic MS criteria. New criteria sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were determined.\n\nResults: Altogether 101 patients were included. Of these, 86 patients converted to MS (McDonald 2005/Poser) during the follow-up. The mean follow-up time was 7.3 +/- 3.2 years (range 1.8-11 selleck screening library years). Sensitivity was 84%, specificity 80%, PPV 96%, NPV 46% and accuracy 82%. The sub-analysis applied only to non-European descendants (mestizos, natives and zambos) showed a high level of accuracy for these new diagnostic criteria in this local ethnic/genetic population (sensitivity 77%, specificity 72%, PPV 94%, NPV 38%).\n\nConclusions: This study assessing McDonald 2010 criteria in a Latin-American population may contribute to its international validation.”
