Toxoplasmosis is a parasitic disease caused by infection with Toxoplasma gondii, capable of infecting a wide range of hosts. The parasite exhibits a broad genetic diversity, necessitating genotypic characterization for genotype identification and associations with epidemiological information. Therefore, the Restriction Fragment Length Polymorphism (RFLP) technique is used for characterization.

Article Synopsis
- * A study examined 200 dogs in Rio Grande do Sul, Brazil, for the presence of Leishmania spp., using PCR techniques; 26.5% tested positive, all for L. infantum, with an average age of 5.08 years among the infected.
- * Clinical signs in infected dogs varied, with some showing symptoms like hepatomegaly and anemia; notable pathological findings included evidence of distemper and meningitis in certain cases.
In vitro antimicrobial, antibiofilm photodynamic activity, and molecular dynamic simulations of tetra-cationic porphyrinmembrane interactions against foodborne microorganisms.

This manuscript presents a new report on the in vitro antimicrobial photo-inactivation of foodborne microorganisms (Salmonella spp. and Listeria monocytogenes) using tetra-cationic porphyrins. Isomeric tetra-cationic porphyrins (3MeTPyP, 4MeTPyP, 3PtTPyP, and 4PtTPyP) were tested, and antimicrobial activity assays were performed at specific photosensitizer concentrations under dark and white-light LED irradiation conditions.

Article Synopsis
- * This study conducted the first molecular identification of these parasites in wild boars in Brazil, finding that 31.9% of the 210 samples were positive for Sarcocystis spp., with a majority identified as S. miescheriana and a smaller portion as the zoonotic S. suihominis.
- * The research highlights the zoonotic risks to humans from contaminated pork products and confirms the PCR-RFLP
