Background: Toxoplasma gondii is a zoonotic protozoan parasite with a heteroxenus life cycle that involves felids as the definitive hosts and any warm-blooded animal, including humans, as intermediate hosts. Cats are key players in parasite transmission as they are capable of shedding high numbers of oocysts in their feces that contaminate the environment.
Methods: The study was performed on 31 domestic cats (31.
Artemisinin is a powerful antimalarial drug, useful in the treatment of many diseases, including chickens coccidiosis. Its toxic effects have been well studied in humans and experimental animals, but not sufficiently in broiler chickens. Therefore, in the present study, we aimed to assess the side effects of artemisinin in chickens, by measuring the serum level of proteins and enzymes (ALT, AST, GGT, ALP, CK), by histopathological examination and by the evaluation of relative weight of organs (liver, kidney, heart).

- The study aimed to create two cost-effective rat models of inflammatory bowel diseases (IBD) using dextran sodium sulfate (DSS) and 2, 4, 6-trinitrobenzene sulfonic acid (TNBS) to better understand the diseases.
- Researchers assessed the impact of these compounds on oxidative stress, particularly looking at glutathione peroxidase (GPx) activity, and compared the resulting histological changes in the rats' colons.
- Both models produced characteristics similar to human conditions, showing that DSS and TNBS can be reliable for studying acute inflammation in IBD.
Four experiments were conceived in order to test the efficacy of artemisinin, a sesquiterpene lactone derived from Artemisia annua, in single experimental infection of broiler chickens with Eimeria acervulina (1 × 10(5) oocysts), Eimeria maxima (5 × 10(4) oocysts) or Eimeria tenella (1 × 10(4) oocysts), and mixed infection with all 3 species (3.2 × 10(4) Eimeria spp. oocysts).

Tests performed under controlled laboratory conditions at 21 °C, 80 % RH and 27 °C, RH 80 %, on ten fully engorged female ticks collected from naturally infested goats, in Cluj County, Romania. Hatched larvae were fed on white mice and the nymphs and adults on guinea pigs.
