Ítem Synanthropic Cockroaches (Blattidae: Periplaneta spp.) Harbor Pathogenic Leptospira in Colombia(Entomological Society of America, 2016-06-01) Bonilla, ÁlvaroLeptospirosis cases in Colombia are typically linked to peridomestic rodents; however, empirical data suggest that Leptospira-infected patients with no apparent exposure to these reservoirs are common. Cockroaches (Periplaneta spp.) have equal or greater interaction with humans than rodents, yet their potential role as carriers of Leptospira has not been assessed. We determined if pathogenic Leptospira is harbored by Periplaneta spp. in Cali (Colombia) and the variables influencing this relationship. Fifty-nine cockroaches were captured from seven sites and DNA was extracted from the body surface and digestive tract for a multiplex polymerase chain reaction, targeting genes secY and flaB. Logistic regression models and proportion tests showed a higher likelihood for Leptospira to be isolated from body surfaces (P>0.001) and from individuals inside houses (six times more likely). These findings are the first to demonstrate an association between Periplaneta spp. and Leptospira, suggesting the need to investigate the potential for cockroaches to serve as reservoirs or transport hosts for Leptospira.Ítem Enfoque diagnóstico molecular utilizando secuenciación exómica en las distrofias musculares cintura-cadera(Universidad Nacional de Colombia, 2016-01-01) Lois, SergioBackground. Limb-girdle muscular dystrophy type 1B has a dominant autosomal inheritance pattern and is caused by a mutation in the LMNA gene. This disease has a major neuromuscular and cardiac compromise; furthermore, it belongs to the limb-girdle muscular dystrophies. Objective. To make a clinical and molecular confirmatory diagnosis in a patient with proximal muscular weakness and cardiac symptoms using whole exome sequencing. Materials and Methods. This is the case of a 57 year old patient with a slowly progressive proximal muscular weakness and cardiac compromise; furthermore, the patient has many relatives with the same clinical history. Whole exome sequencing with Sanger confirmation and bioinformatics analysis was performed on the found mutation.
