"Cryptococcus adalah jamur penyebab tersering pada pasien imunokompromi. Pada penelitian ini, 200 isolat yang berasal dari cairan otak 20 pasien terinfeksi HIV ditetapkan spesies dan serotipenya, serta kepekaannya terhadap obat antifungal (amfoterisin B, flukonazol, vorikonazol, ketokonazol, flusitosin). Spesies dan serotipe Cryptococcus ditetapkan menggunakan medium canavanine glycine bromthymol blue (CGB) dan medium creatinine dextrose bromthymol thymine (CDBT), sementara kepekaan terhadap antifungal diuji dengan metode difusi cakram, NCCLS M-44A, approved guidelines. Spesies C. neoformans ditemukan pada 170 isolat (85%), dengan seluruhnya adalah serotipe A dan 30 isolat adalah C. gattii. Infeksi tunggal C. neoformans ditemukan pada 10 pasien, infeksi tunggal C. gattii pada satu pasien, dan infeksi campuran pada 9 pasien. Cryptococcus spp sensitif terhadap amfoterisin B (93,5%), flukonazol (88,5%), vorikonazol (100%) dan ketokonazol (98%). Resistensi primer terhadap flusitosin ditemukan pada semua isolat C. neoformans dan C. gattii (100%) sebelum dan sesudah terapi. Secara keseluruhan, C. gattii kurang peka dibandingkan C. neoformans terhadap seluruh obat antifungal.

Cryptococcus are common causes of mycoses in imunocompromised patient. In this study, 200 clinical cerebrospinal fluid from 20 HIV patient?s isolates of Cryptococcus were determine their species and serotypes, and their susceptibilities to antifungal (amphotericin B, fluconazole, voriconazole, ketoconazole, flucytosine) were analyzed. Cryptococcus species and serotypes were determined by canavanine glycine bromthymol blue (CGB) medium and creatinine dextrose bromthymol thymine (CDBT) medium, meanwhile antifungal susceptibilities were determined by disk diffusion method, NCCLS M-44A, approved guidelines. Species C. neoformans was found in 170 (85%) isolate with all of them was serotipe A dan 30 isolates (15%) were C. gattii. Single infection of C. neoformans was found in 10 patients, single infection of C. gattii in one patient and mixed infection in nine patients. Cryptococcus spp susceptible to amphotericin B (93,5%), fluconazole (88,5%), voriconazole (100%) and ketoconazole (98%). Primary resistance to flucytosine was found in all isolates C. neoformans and C. gattii (100%) before and after therapy. In general, C.gattii was less susceptible than C. neoformans to all drug tested. "

"[ABSTRAKToxoplasma gondii merupakan protozoa intraselular obligat yang tersebar di seluruh dunia. Infeksi yang diakibatkannya disebut toksoplasmosis, dan diperkirakan sekitar sepertiga populasi dunia terinfeksi T. gondii. Toksoplasmosis akan menjadi masalah bahkan dapat mengancam jiwa bila infeksi terjadi pada orang imunokompromi. Ensefalitis toksoplasma (ET) terjadi akibat reaktivasi infeksi laten T. gondii, dan merupakan masalah yang sering terjadi pada pasien AIDS, terutama pada stadium akhir.Untuk menegakkan diagnosis pasti penyebab kelainan SSP pada pasien AIDS sangatlah sulit, karena banyaknya kemungkinan penyebab infeksi lain seperti bakteri, virus, dan jamur. Diagnosis ET ditegakkan hanya berdasarkan asumsi dari gejala klinis, gambaran radiologi, dan respons terhadap terapi yang diberikan. Pemeriksaan kadar IgG anti-Toxoplasma pada cairan organ yang terinfeksi T. gondii jarang dilakukan. Selama ini studi-studi lebih banyak yang memeriksa kadar IgG anti-Toxoplasma pada serum. Oleh karena masih jarangnya penelitian yang menggunakan CSS untuk penegakan diagnosis ET dan untuk mengetahui apakah kadar IgG anti-Toxoplasma pada CSS bermakna dalam menegakkan diagnosis ET, maka penelitian mengenai hal tersebut dilakukan pada pasien HIV & AIDS dengan dugaan meningitis.Dari 50 sampel CSS pasien AIDS yang dikirim ke Laboratorium Parasitologi FKUI, 24 (48%) positif dan 26 (52%) negatif IgG anti-Toxoplasma. Dari IgG positif, 5 (20,83%) kadar tinggi, dan 19 (79,17%) kadar rendah. Tidak ada perbedaan bermakna antara kadar IgG anti-Toxoplasma dengan hasil pencitraan maupun diagnosis klinis ET. Tidak ada hubungan antara kadar IgG anti-Toxoplasma dengan riwayat terapi profilaksis ko-trimoksazol.

ABSTRACTToxoplasma gondii is obligate intracellular parasite that spread over the world. Toxoplasmosis, infection of this parasite, infected over one third world population. Toxoplasmosis become problem and life threatening in immunocompromised patients. Toxoplasma encephalitis (TE) is reactivation of latent infection of T. gondii, and usually manifest in severe stage of AIDS.Diagnosis of central nervous system infection in AIDS is very difficult, because many possibilities of infection that caused by bacteri, virus, and fungi. TE is only diagnosed by asumption of clinical signs, radiology, and therapeutic respons. The examination of IgG anti-Toxoplasma in organ fluid was rare. Because of this reason and to answer, is IgG anti-Toxoplasma in cerebro spinal fluid has important meaning for diagnosing TE, this study was done in HIV infection & AIDS patients with meningitis.From 50 LCS of AIDS patients that sent to Parasitology Laboratorium FKUI, 24 (48%) were positive, and 26 (52%) were negative of IgG anti-Toxoplasma. From IgG positive samples, 5 (20,83%) were high, and 19 (79,17%) were in low level. There is no difference between IgG anti-Toxoplasma level with radiology appearence, and with clinical diagnose for TE. No difference between IgG anti-Toxoplasma level with history of cotrimoxazole as prophylaxis therapy.;Toxoplasma gondii is obligate intracellular parasite that spread over the world.
