Are opossums a relevant factor associated with asymptomatic Leishmania infection in the outskirts of the largest Brazilian cities? BJID
Carranza-Tamayo,César Omar; Werneck,Guilherme Loureiro; Romero,Gustavo Adolfo Sierra.
Abstract A population survey was conducted to explore the prevalence and factors associated with Leishmania infection in the Fercal region of the Federal District. The Fercal region is a group of neighborhoods in Brasília in which the first cases of visceral leishmaniasis were described. Leishmania infection was established by a positive leishmanin test. Although other tests were performed in the study (an immunochromatographic assay (Kalazar detect®) and a molecular assay), only the leishmanin skin test provided sufficient results for the measurement of the disease prevalence. Data on the epidemiological, clinical and environmental characteristics of individuals were collected along with the diagnostic tests. After sampling and enrollment, seven hundred...

Congenitally transmitted visceral leishmaniasis: report of two brazilian human cases BJID
Mescouto-Borges,Myrlena Regina Machado; Maués,Érika; Costa,Dorcas Lamounier; Pranchevicius,Maria Cristina da Silva; Romero,Gustavo Adolfo Sierra.
Visceral leishmaniasis is a relevant public health problem worldwide. Most of the reported cases in Latin America are from Brazil. Herein we report two human cases of congenitally transmitted visceral leishmaniasis in two patients who developed symptoms during pregnancy. The diagnosis was made by visual examination of Leishmania parasites in bone marrow aspirates of the mothers and by detecting parasite kDNA in bone marrow samples of the newborn children using polymerase chain reaction.

Early-onset neonatal sepsis and the implementation of group B streptococcus prophylaxis in a Brazilian maternity hospital: a descriptive study BJID
Freitas,Felipe Teixeira de Mello; Romero,Gustavo Adolfo Sierra.
Abstract Objectives: To describe early-onset neonatal sepsis (EOS) epidemiology in a public maternity hospital in Brasilia, Brazil. Methods: We defined EOS as a positive blood culture result obtained from infants aged ≤72 hours of life plus treatment with antibiotic therapy for ≥5 days. Incidence was calculated based on the number of cases and total live births (LB). This is a descriptive study comparing the period of 2012–2013 with the period of 2014–September 2015, before and after implementation of antibiotic prophylaxis during labor for group B streptococcus (GBS) prevention, respectively. Results: Overall, 36 infants developed EOS among 21,219 LB (1.7 cases per 1000 LB) and 16 died (case fatality rate of 44%). From 2014, 305 vaginal-rectal swabs...
