ABSTRACT Toxoplasma gondii and Neospora caninum (both Apicomplexa) are closely related cyst-forming coccidian parasites that differ significantly in their host ranges and ability to cause disease. Unlike eutherian mammals, Australian marsupials (metatherian mammals) have long been thought to be highly susceptible to toxoplasmosis and neosporosis because of their historical isolation from the parasites. In this study, the carnivorous fat-tailed dunnart (Sminthopsis crassicaudata) was used as a disease model to investigate the immune response and susceptibility to infection of an Australian marsupial to T. gondii and N. caninum. The disease outcome was more severe in N. caninum-infected dunnarts than in T. gondii-infected dunnarts, as shown by the severity of clinical and histopathological features of disease and higher tissue parasite burdens in the tissues evaluated. Transcriptome sequencing (RNA-seq) of spleens from infected dunnarts and mitogen-stimulated dunnart splenocytes was used to define the cytokine repertoires. Changes in mRNA expression during the time course of infection were measured using quantitative reverse transcription-PCR (qRT-PCR) for key Th1 (gamma interferon [IFN-γ] and tumor necrosis factor alpha [TNF-α]), Th2 (interleukin 4 [IL-4] and IL-6), and Th17 (IL-17A) cytokines. The results show qualitative differences in cytokine responses by the fat-tailed dunnart to infection with N. caninum and T. gondii. Dunnarts infected with T. gondii were capable of mounting a more effective Th1 immune response than those infected with N. caninum, indicating the role of the immune response in the outcome scenarios of parasite infection in this marsupial mammal.

Penelitian ini bertujuan mengetahui peningkatan tumor necrosis factor-alpha (TNF-α) dan indeks apoptosis pada tulang mencit yang  diinfeksi Toxoplasma gondii (T. gondii). Tiga puluh dua ekor mencit dibagi menjadi dua kelompok. Kelompok 1 (K1), merupakan kelompok kontrol, tidak diinfeksi sedangkan Kelompok 2 (K2) diinfeksi dengan 10 takizoit T. gondii secara intraperitoneal. Enam hari setelah infeksi mencit dikorbankan, diambil tulang femur dan dilakukan pembuatan preparat histologis dengan pengecatan immunohistochemistry (IHC) dan Tunel assay. Hasil penelitian menunjukkan jumlah sel tulang yang mengekspresikan TNF-α pada K2 (27,04±6,92) berbeda sangat nyata dibandingkan dengan K1 (11,42±3,92). Indeks apoptosis pada K1 dan K2 masing-masing adalah 9,17±3,04 dan 16,28±3,37. Dari hasil penelitian disimpulkan bahwa infeksi T. gondii meningkatkan TNF-α dan indeks apoptosis sel tulang femur.
