Presentation Transcript

  1. Aspek Biologi Bakteri

  2. Proses Infeksi Organism Exposure Mekanisme Resistensi Mekanisme Penolakan Secara Non-specific Kekebalan Treatment Infeksi Kesembuhan InfeksiKronis

  3. Faktor Utama • Organisme Penginfeksi • Jumlah • Jenis • Resistensi yang diinfeksi • Mekanisme resistensi bawaan • Immunitas

  4. Karakteristik Patogen • Attachment • Invasion • Menghasilkan enzymes yg merusak jaringan • Collagenase, hyaluronidase, streptokinase • Avoiding Defenses

  5. Avoiding Defenses • Kapsula • Menghambat Mekanisme Pertahanan (phagocytosis, immunity) • Menghasilkan inhibitor • Menyerap antibodi • Bertahan dalam Sel inang (dlm sel phagocytes) • Variasi Antigen • Selama infeksi • Diantara siklus infeksi

  6. Penyebab • Gram Positif bacteria • Gram Negatif bacteria • Mycoplasma

  7. Dinding Sel Gram Positif

  8. Dinding Sel Gram Negatif

  9. Perbandingan Struktur

  10. Bakteri Gram Positif • Streptococcus agalactiae • Other Streptococcus sp. • uberus • dysgalactiae • Staphylacoccus aureus • dll

  11. Staphylococcus aureus • Penyebab berbagai macam penyakit • Infeksi kulit, abses, pencernaan • Sangat invasif • Sangat sulit disembuhkan

  12. Bakteri Gram Negatif • Eschericia coli, Klebsiella pneumonia • Hidup di alam, beberapa bersifat patogen • Infeksi berat • Dapat disembuhkan secara total

  13. Lipopolysakarida • Disebut sebagai: • LPS • atau Endotoxin

  14. Mycoplasma • Hanya beberapa jenis • Tanpa dinding sel • Parasit Intracellular • Banyak terdapat di alam • Sangat sulit dideteksi • Beberapa resisten terhadap antibiotika
