Teaching method

Theoretical and theory/practical classes, in which the basic concepts to be taught, will be passed with the support of the methods type presentations (PowerPoint). Practical lessons where methods and practical techniques presented in lectures and theoretical-practical will be applied.

Evaluation method

Students with at least 2/3 of frequency are evaluated by final exam. Rating scale of 0 to 20. Approval rating equal to or greater than 10.

Subject matter

I. Structure, metabolism and physiology of bacterial cells. Gram-negative and Gram-positive bacteria- Anaerobic bacteria. Spirochetes. Epidemiological, microbiological, clinical. Identification of the Gram negative bacilli: Enterobacteriaceae and Pseudomonas sp. and of the Gram positive cocci: Staphylococcus sp and Streptococcus.
II. Introduction to Virology. Important Virology milestones. General properties of viruses. The relative size of viruses. Structure and symmetry (helical and icosahedral). Complex and mixed morphologies. Classification (main criteria), taxonomy and nomenclature of viruses. Types and structures of viral genomes. Strategies for viral mRNA synthesis: the Baltimore classification. Steps of the viral replication cycle. Isolation and production of animal viruses: susceptible and permissive cellular systems. Animals, embryonated chicken eggs and cell culture. Titration of infectious viruses. Origin and evolution of viruses. Evolution under the effect of natural selection or as a result of stochastic effects. Bootleneck effect and its consequences on the fitness of viral populations. Mutation rates in RNA and DNA viruses, recombination and redistribution of genomic segments. Analysis of virus stability to physicochemical agents by determining the title of a viral suspension using plaque assays.
III. Introduction to Medical Mycology. Fungi definition. Characteristics of the fungi, somatic structure, reproduction of the fungal cell. Clinical classification of fungal infections: superficial mycoses, subcutaneous and systemic invasive. Opportunistic mycoses.
