1. Avaliação do efeito tripanocida do eupomatenóide-5 por meio de abordagens de biologia celular e bioquímica : um possível mecanismo de ação
Chagas disease is considered a neglected disease that affects millions of people, but does not have an appropriate and effective treatment. The etiologic agent is the protozoan Trypanosoma cruzi that presents a complex life cycle alternating between a vertebrate host and an invertebrate. In the search for more effective and less toxic drugs, the research for

2. Regulation of enteropathogenic Escherichia coli (EPEC) adhesion by genes related to nutrional shortage and stress. / Regulação da adesão de Escherichia coli enteropatogênica (EPEC) por genes de resposta à limitação nutricional e estresse.
Enteropathogenic E. coli (EPEC) is one of the causes of diarrhea in children. Phosphate (Pi) shortage induces transcription of the genes known as the PHO regulon. These genes are controlled by the Pst system, that is also a high-affinity Pi transporter, and represses PHO expression under Pi-replete conditions. PHO is also controlled by the two-component syst

3. Sequence-based identification of microbial pathogens: a reconsideration of Koch's postulates.
Over 100 years ago, Robert Koch introduced his ideas about how to prove a causal relationship between a microorganism and a disease. Koch's postulates created a scientific standard for causal evidence that established the credibility of microbes as pathogens and led to the development of modern microbiology. In more recent times, Koch's postulates have evolv

4. Tritrichomonas foetus Induces Apoptotic Cell Death in Bovine Vaginal Epithelial Cells
Tritrichomonas foetus is a serious veterinary pathogen, causing bovine trichomoniasis, a sexually transmitted disease leading to infertility and abortion. T. foetus infects the mucosal surfaces of the reproductive tract. Infection with T. foetus leads to apoptotic cell death of bovine vaginal epithelial cells (BVECs) in culture. An affinity-purified cysteine

5. Cytometric detection of mycobacterial surface antigens: exposure of mannosyl epitopes and of the arabinan segment of arabinomannans.
The physical arrangement of cell envelope components leads to the exposure of selected structural motifs which in turn may influence host-parasite interactions. To gain insight into the exposed epitopes, the present study describes a flow cytometric method designed to probe defined molecules on dispersed mycobacteria. The hydrophobic fluorophore N-hexadecano
