Medical Microbiology 

Photodynamic therapy by exogenic porphyrins displays potent cytotoxic activity against Gram positive bacteria. For Gram-negative bacteria, photosensitization is possible only with a positively-charged porphyrin. The photodynamic effects on the viability of bacteria and yeasts are very efficient. Mechanisms of photoinactivation and target sites in the bacterial cell are investigated. Examination by electron microscopy of damage in intracellular structures, as well as the changes in the elemental content of the bacterial cells, is studied.

Photodynamic therapy by endogenic porphyrins is based on the ability of d-amino levulinic acid (ALA) to induce endogenic synthesis of porphyrins. Upon illumination, photoinactivation occurs, followed by intracellular damages and changes in the elemental content. The role of the endogenic porphyrins in the photodynamic process is studied.

Structure and function of pore-forming proteins isolated from the outer membrane of Gram negative bacterial. The penetration ability of sugars, amino acids and antibiotics through these porins is investigated. Sequencing of the proteins and isolation of the analogous genes are also investigated. Prediction of the secondary structure and finding the sequences of the loops that are very important for the pathogenic behavior of the microorganism, are investigated.
