HIV has become increasingly prevalent in the Northeast region of Brazil where Leishmania infantum chagasi is endemic, and concurrent AIDS and visceral leishmaniasis (VL) has emerged. In this study, persons with HIV/AIDS and VL (n = 17) had a mean age of 37.3 years (range 29–53 years) compared with 12.5 years (1–80 years) for persons with VL alone (n = 2836). Males accounted for 88% of cases versus 65%. The mean CD4 count and antileishmanial antibody titre were lower and recurrence of VL and death were more likely with co-infection. Considering the prevalences of L.i. chagasi and HIV in the region, this may herald the emergence of an important public health problem.

This work started from observations about comments, readings and in the media in general about education in contemporary society, and the importance of teachers and their responsibility in this context, since most families are known to believe that the school environment is the ideal place for your child's education, delegating to the teacher their education, which sometimes already deteriorates, regardless of school levels. We opted for searching for articles on Buylling, on the internet, books or magazines. The research is repeated, so there were few unpublished articles, around 13.

Currently, microsporidia are phylogenetically characterized as fungi, genetic and functional suffering significant losses, resulting from lower eukaryotic genomes described to date. Lack mitochondria, and there are about 100 genera and 1,400 species. The objective of this study was to investigate what has been published regarding the incidence of infection with microsporidia in animals of estimation.
