Toxoplasma gondii infection in marine mammals is intriguing and indicative of contamination of the ocean environment with oocysts. T. gondii was identified in a Hawaiian monk seal (Monachus schauinslandi) that had visceral and cerebral lesions. Tachyzoites were found in the lymph nodes, spleen, diaphragm, heart, adrenal glands, and brain. A few tissue cysts were found in sections of the cerebrum. The diagnosis was confirmed serologically, by immunohistochemical staining with T. gondii-specific…

Prevalence of Toxoplasma gondii infection among small mammals in Tatarstan, Russian Federation
- BiologyScientific reports
- 2021
Toxoplasma gondii infection prevalence was evaluated in brain tissues from 474 small mammals captured at 26 trapping points in urban and rural areas of Tatarstan, Russian Federation and showed that the trapping area (rural or urban) significantly contributed to T. gondius positivity.

Findings reveal that T. gondii is prevalent across Kaua’i and variability offers insight to the factors that might predict T. Gondii seropositivity across the landscape, and likewise predict exposure risks for endangered wildlife.
Fatal Systemic Toxoplasmosis by a Novel Non-archetypal Toxoplasma gondii in a Bryde’s Whale (Balaenoptera edeni)

The genotyping by microsatellite technique employed 15 markers and confirmed a unique non-archetypal T. gondii strain, designated as PS-TgBaledBrES1, representing the first record of toxoplasmosis in a Bryde’s whale and setting the baseline knowledge for future research in marine mammals from South America.

The association between mangroves and higher trematode prevalence is most likely because birds use mangrove sites as perch sites and this results in local transmission to snails.
