Novel antibiotics are needed to overcome the challenge of continually evolving bacterial resistance. This has led to a renewed interest in mechanistic studies of once popular antibiotics like chloramphenicol (CAM). Chloramphenicol acetyltransferases (CATs) are enzymes that covalently modify CAM, rendering it inactive against its target, the ribosome, and thereby causing resistance to CAM. Of th...

The scale-up estimator is a network-based estimator for the size of hidden or hard to count subpopulations. Several issues arise in the public health context when the aim is the estimation of injuries occurring in a certain population, where two common problems are present: (a) Small injuries are usually difficult to observe and rarely reported in the official data and (b) people are not always...

Os animais silvestres hospedam uma ampla gama de parasitas que são agentes doenças primárias ou oportunistas. O estudo da parasitologia é essencial, pois esses hospedeiros e reservatórios, influenciando o ecossistema ambiente natural doméstico. De agosto 2007 a 2012, sete felinos selvagens adultos foram encontrados mortos em rodovias federais estaduais. Entre eles, havia três Puma concolor (doi...

Background. Toxocariasis is an important zoonotic infection, especially in tropical areas. One of the significant challenges serodiagnosis human toxocariasis cross-reaction Toxocara antigens with other parasites due to their relatively similar glycan structures. Removing structure from excretory-secretory (TES) may increase efficacy these diagnosis toxocariasis. The current study aimed assess d...
