25. Advances in Cryptococcus genomics: insights into the evolution of pathogenesis
Cryptococcus species are the causative agents of cryptococcal meningitis, a significant source of mortality in immunocompromised individuals. Initial work on the molecular epidemiology of this fungal pathogen utilized genotyping approaches to describe the genetic diversity and biogeography of two species, Cryptococcus neoformans and Cryptococcus gattii.

26. Retrospective evaluation of the clinical characteristics associated with Corynebacterium species bacteremia
ABSTRACT Objectives: Corynebacterium spp. are becoming recognized as pathogens that potentially cause various infections. We aimed to evaluate the clinical characteristics associated with Corynebacterium spp. bacteremia. Patients and methods: We retrospectively reviewed the medical records of all adult patients who had positive blood cultures for Corynebac

27. Captive wild birds as reservoirs of enteropathogenic E. coli (EPEC) and Shiga-toxin producing E. coli (STEC)
ABSTRACT Psittacine birds have been identified as reservoirs of diarrheagenic Escherichia coli, a subset of pathogens associated with mortality of children in tropical countries. The role of other orders of birds as source of infection is unclear. The aim of this study was to perform the molecular diagnosis of infection with diarrheagenic E. coli in 10 diffe

28. Unrecognized pediatric and adult family members of children with acute brucellosis
Abstract Background and aim Brucellosis is an infectious, contagious and zoonotic disease that occurs worldwide. The family members of an index case of brucellosis may be especially susceptible, due to sharing the same source of infection and similar risk factors for brucellosis. In this study, we propose to screen pediatric and adult family members of bruc

29. Exposure source prevalence is associated with gender in hepatitis C virus patients from Rio de Janeiro, Brazil
BACKGROUND Hepatitis C virus (HCV) infection is a worldwide public health problem. A characterisation of the differences in exposure sources among genders will enable improvements in surveillance actions. METHODS Exposure data were obtained for 1180 confirmed HCV cases Brazil’s mandatory reporting to epidemiological surveillance, which was directed by

30. Environmental aspects related to tuberculosis and intestinal parasites in a low-income community of the Brazilian Amazon
ABSTRACT We carried out a cross-sectional study from January to December 2015 on 1,425 inhabitants from a floating population in the Brazilian Amazon (Murinin district, Pará State) to describe the population-based prevalence of tuberculosis (TB) from 2011 to 2014, recent TB contacts (rCts) latently infected with Mycobacterium tuberculosis (LTBI) , the cover

31. Group B Streptococcus detection in pregnant women via culture and PCR methods
Abstract INTRODUCTION: Group B Streptococcus (GBS), a source of neonatal infection, colonizes the gastrointestinal and genitourinary tracts of pregnant women. Routine screening for maternal GBS in late pregnancy and consequent intrapartum antibiotic prophylaxis have reduced the incidence of early-onset GBS neonatal infection. The aim of this study was to e

32. Snow's case revisited: new tool in geographic profiling of epidemiology
Abstract Geographic Profiling technique is used to find the origin of a series of crimes. The method was recently extended to other fields. One of the best renowned data in epidemiology is that by John Snow during an outburst of cholera in London. We wrote Python scripts to perform the analyses to apply the Geographic Profiling for individuating the starting

33. Septic Pulmonary Embolism Requiring Critical Care: Clinicoradiological Spectrum, Causative Pathogens and Outcomes
OBJECTIVES: Septic pulmonary embolism is an uncommon but life-threatening disorder. However, data on patients with septic pulmonary embolism who require critical care have not been well reported. This study elucidated the clinicoradiological spectrum, causative pathogens and outcomes of septic pulmonary embolism in patients requiring critical care. METHODS

34. Characteristics of gonorrhea and syphilis cases among the Roma ethnic group in Belgrade, Serbia
Abstract Background The Roma ethnic group is the largest and most marginalized minority in Europe, believed to be vulnerable to sexually transmitted infections. Aim The purpose of the study was to investigate frequency and characteristics of gonorrhea and syphilis among the Roma population in Belgrade. Methods Data from the City Institute for Skin and Ven

35. Comparison of optical microscopy and quantitative polymerase chain reaction for estimating parasitaemia in patients with kala-azar and modelling infectiousness to the vector Lutzomyia longipalpis
Currently, the only method for identifying infective hosts with Leishmania infantum to the vector Lutzomyia longipalpis is xenodiagnosis. More recently, quantitative polymerase chain reaction (qPCR) has been used to model human reservoir competence by assuming that detection of parasite DNA indicates the presence of viable parasites for infecting vectors.

36. Pathogenicity and phenotypic sulfadiazine resistance of Toxoplasma gondii isolates obtained from livestock in northeastern Brazil
Toxoplasma gondii is the causative protozoan agent of toxoplasmosis, which is a common infection that is widely distributed worldwide. Studies revealed stronger clonal strains in North America and Europe and genetic diversity in South American strains. Our study aimed to differentiate the pathogenicity and sulfadiazine resistance of three T. gondii isolates
