Toxoplasmosis is a protozoan infection caused by Toxoplasma gondii. We report a case of Toxoplasma gondii and Clostridium perfringens co-infection complicating uterine gas gangrene following a term pregnancy. The histological examination of the necrotic uterine tissues and uterine swab cultures obtained at laparotomy revealed T. gondii and C. perfringens, respectively. Treatment was administered with bactericidal activity against both pathogens and the patient had an uneventful post-operative recovery. Although there have been some cases that have documented an association between toxoplasmosis and non-uterine C. perfringens infection, such a relationship has not been established. It is of interest to determine if the presence of both organisms can explain the severe myonecrosis that occurs in some cases of uterine gas gangrene.

The intracellular protozoan Toxoplasma gondii manipulates host cell signaling to avoid targeting by autophagosomes and lysosomal degradation. Epidermal Growth Factor Receptor (EGFR) is a mediator of this survival strategy. However, EGFR expression is limited in the brain and retina, organs affected in toxoplasmosis.

These events are associated with innate training and can have long-term impacts on hematopoietic stem and progenitor cell (HSPC) development but can also compromise their function. While many cytokines support emergency myelopoiesis, less is known about the mechanisms that temper these events.

Unlabelled: The southern brown bandicoot (Isoodon obesulus obesulus) is a small, endangered, Australian, ground-dwelling marsupial. Apart from isolated necropsy reports, there has not been a systematic investigation into the health and causes of death for this species.
Objective: To investigate and document the causes of death and the parasites of free-ranging populations of southern brown bandicoots in southern, central Victoria, Australia.

Toxoplasma gondii is an intracellular and parasitic protozoon that harbors specialized cellular structures and molecular mechanisms, including the Plant-like Vacuolar Compartment (PLVAC). The PLVAC performs multifaceted roles in the parasite, contributing to ion homeostasis, proteolysis, pH regulation, and autophagy. Despite significant efforts over the past decade to characterize the PLVAC, the proteins localized to this organelle remain largely unidentified.
