bachelor's at MEDICINA VETERINÁRIA from Universidade Estadual Paulista Júlio de Mesquita Filho (1978), master's at Microbiology from Universidade de São Paulo (1983) and doctorate at Microbiology from Universidade de São Paulo (1985). He is currently full professor at Universidade Estadual Paulista Júlio de Mesquita Filho and professor titular at Universidade Estadual Paulista Júlio de Mesquita Filho. Has experience in Veterinary Medicine, focusing on Veterinary Preventive Medicine, acting on the following subjects: salmonella, aves comerciais, salmonella gallinarum, salmonella enteritidis and aves.

Assays done in mammals has shown that enteric salmonellas are able to use the inflammatory process provoked by them as a source of energy to survive and multiply inside the gut. This process is associated with the use of tetrathionate (ttr) as a by-product of the host inflammatory gut response. After the production of tetrathionate it becomes possible to use propanediol (pdu) as an energy…
The aviculture is an important segment of animal production. The intensive system favours the emergence of various infections, like salmonellosis. The fowl typhoid, caused by Salmonella Gallinarum biovar Gallinarum (SG) causes high mortality rate on the flock, whereas Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST) outcomes in disorders to the poultry production because may in…
Salmonella enterica subsp. enterica serovar Gallinarum biovar Gallinarum (SG) is the etiologic agent of fowl typhoid, a severe disease that occurs in birds of any age. Salmonella enterica subsp. enterica serovar Gallinarum biovar Pullorum (SP) is the pathogen responsible for pullorum disease, a severe systemic illness which occurs mainly in chicks, induces a carrier state in some of them …

Paratypic Salmonella is efficient at carrying out the process of intestinal inflammation and taking advantage of this to win competition with other microorganisms in the gut microbiome. In mammals the process is associated with the use of tetrathionate (Ttr), a by-product of intestinal inflammation, by Salmonella spp., a process that also involves the use of propanediol (Pdu) as an energy…
The Brazilian poultry chain has great prominence in the market, being characterized by quality products and low cost. Commercial-intensive egg production has increased, highlighting the need for pathogen control programs on farms, including bacteria of the genus Salmonella. With the entry of paratyphoid serovars in farms, the affected birds can harbor them in the digestive tract, being a …
Fowl typhoid is an important disease for the poultry industry, due to the damage caused by the highest chicken mortality, which can reach 80% or more. Among the main biosecurity measures are the correct management in the poultry house and the adoption of vaccines. The present study aims to continue the previous work of this research group with a mutant strain of Salmonella Gallinarum cont…

The indiscriminate use of antimicrobials in animal production has left residues in products of animal origin and in the environment, since after administration there is partial metabolization of the drug, and the remainder being excreted in an unalterable way or as active metabolites in feces and urine. This is often associated with increased bacterial resistance to different classes of a…
Salmonella Enteritidis (SE), Salmonella Typhimurium (ST), and Salmonella Heidelberg (SH) are among the most prevalent paratypical serovars found in birds and humans. In this study, the evaluation of intestinal colonization and the systemic infection by means of bacterial count in cecal content and liver in 3lineage types of commercial birds inoculated with SE, ST, and SH and previously in…

Bacteria of Salmonella genus are pathogens that can infect animals and humans. Some Salmonella spp. serovars can settle down in poultry animals, in the digestive tract, and be disseminated without causing any apparent clinical signs. However, the presence of these bacteria can pose a risk to public health, making poultry products a potential source of infection to humans. Little is known …
It is common the emergence of human foodborne diseases outbreaks worldwide caused by the consumption of poultry products contaminated with Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST). Experiments performed with mammals has shown that enteric salmonellas are able to use the inflammatory process provoked by them as a source of energy to survive and multiply inside the gut. T…
Salmonella Gallinarum (SG) provokes fowl typhoid, a severe systemic infectious disease that affects gallinaceous of any age and has been considered one of the major poultry health challenges. During the typhoid-like systemic infection in mice caused by S. Typhimurium, bacteria transcribe the mgtC gene. Its function seems to be associated with bacteria replication within macrophages and th…
