1. Análise da diversidade genética em populações de Sclerotinia sclerotiorum / Analysis of genetic diversity in populations of Sclerotinia sclerotiorum
O fungo Sclerotinia sclerotiorum está entre os fitopatógenos mais bem sucedidos, onívoros e sem hospedeiros definido, é considerado um dos patógenos fúngicos mais importantes no mundo. Está distribuído em todas as regiões produtoras, sejam elas temperadas, subtropicais ou tropicais. O fungo produz estruturas de resistência denominadas escleródios,

2. Genetic Diversity and Spoilage Potentials among Pseudomonas spp. Isolated from Fluid Milk Products and Dairy Processing Plants
Degradation of milk components through various enzymatic activities associated with the contamination of dairy products by Pseudomonas spp. can reduce the shelf life of processed milk. Reliable methods for differentiating among Pseudomonas spp. strains are necessary to identify and eliminate specific sources of bacterial contamination from dairy processing s

3. Polymorphisms in the Chlamydia trachomatis Cytotoxin Locus Associated with Ocular and Genital Isolates
Chlamydia trachomatis is a strict human pathogen producing infections that cause medically important chronic inflammatory diseases, such as blinding trachoma and tubal factor infertility. Isolates exist as serotypes that fall into distinct biologic and pathological groups corresponding to differences in infection tissue tropism and invasion properties. Parad

4. Comparative Analysis of Gtf Isozyme Production and Diversity in Isolates of Streptococcus mutans with Different Biofilm Growth Phenotypes
Streptococcus mutans is the main pathogenic agent of dental caries. Glucosyltransferases (Gtfs) produced by these bacteria are important virulence factors because they catalyze the extracellular synthesis of glucans that are necessary for bacterial accumulation in the dental biofilm. The diversity of GtfB and GtfC isozymes was analyzed in 44 genotypes of S.

5. Homologous recombination in Leishmania enriettii.
We have used derivatives of the recently developed stable transfection vector pALT-Neo to formally demonstrate that Leishmania enriettii contains the enzymatic machinery necessary for homologous recombination. This observation has implications for gene regulation, gene amplification, genetic diversity, and the maintenance of tandemly repeated gene families i

6. Modification in the ppk Gene of Helicobacter pylori during Single and Multiple Experimental Murine Infections
The bacterial pathogen Helicobacter pylori is highly adapted to the human stomach, and a high level of polymorphism is observed among clinical isolates. This polymorphism may be the consequence of adaptive changes during colonization, making a strain better able to survive, to evade the immune system, and to provoke a chronic infection. To investigate the me
