- Staphylococcus Aureus

السلام عليكم ورحمة الله وبركاته ازيكم يا دكاترة نظرا لأن جزء الريتن في الفاينال بقا عليه 60% من الدرجة و علشان نساعدكم تهتموا بيه من أول السنة إن شاء الله هننزل للريتن MicroMaps و هي عبارة عن Mind Maps تنظم الإجابة على أسئلة الريتن المهمة في كل درس هننزل إن شاء الله كل درس لوحده علشان تقدروا تراجعوه بسهولة في الماسدج دي

Enzymes and Toxins in Streptococcus pyogenes "Happy Kids play PE" H--> Hylauronidase P--> Peptidase C5a K-->StreptoKinase D--> StreptoDornase LaY--> StreptoLYsin PE--> Streptococcus Pyrogenic Exotoxin

Diseases of Streptococcus Pyogenes ■ Localized (PSSIT بسيط) P --> Pyoderma (impetigo) S --> Scarlet Fever SI --> Surgical wound Infection T -->  Tonsillitis Note: associated with Toxemia ■ Diffuse - Erysipelas - Cellulitis ■ Invasive (NAShR نشر) N --> Necrotizing fascitis A --> Acute endocarditis Sh --> Shock (toxic shock) R --> puRpural sepsis Note: Associated with Bacteremia and Septicemia

فروقات مهمة micro ● ال spores في ال Gram Stain بتبقا unstained لكن في ال modified Zeihl Neelsen بتبقا red ● ال capsule سواء في ال Gram Stain أو Indian Ink بتبقا unstained ● ال indicator اسمه phenol red في حاجتين: 1- Triple Sugar Iron (TSI) 2- Urease test ● ال indicator اسمه neutral red في ال MacConkey ● ال media اسمها Muller Hinton في حاجتين: 1- Disc Diffusion 2- Epsilometer ● ال coagulase test منه نوعين - Tube method --> free coagulase - Slide method --> bound coagulase ● الألوان أغلب ال positive هنلاقيهم بيبدأو ب p أو b - oxidase --> purple - urease & indol --> pink - citrate --> blue

أهم أجزاء life cycle of cestodes هنقسمهم الأول intestinal cestode و tissue cestode مش هيفرق في حاجة أوي بس ال Tissue الوحيدة اللي معانا E.granulosa الباقي كله intestinal Intestinal - أي Definitive Host هيبقى man - أي habitat هتبقى small intestine - أي diagnostic stage هتبقى egg in stool - أي infective stage هتبقى اسم ال larvae • D. latum --> plerocercoid • T. Solium --> Cysticercous cellulosa • T. Saginata --> Cysticercous bovis • All others --> Cystecercoid larvae - أي mode of infection هيبقا Food and water containing....larvae - ال intermediate host دا هنحفظه • D. latum --> Cyclop 1st, Salmon 2nd • T. Solium --> Pig • T. Saginata --> Cattle • All others --> flea بس هتختلف     > D. caninum --> Dog & cat flea     > H. dimminuta or nana --> rodent flea و ال Nana علشان متكرر فيها Na مرتين يبقا ال man ممكن يبقا فيها مرة Definitive host و مرة Intermediate host و ال egg تنفع تبقى diagnostic أو infective stage ناقص بس ال Reservoir host لكل اللي بيبدأوا ب D أو H بس و بيبقى عادة نفس ال Intermediate بس منغير كلمة flea • D. latum --> fish eating animal • D. caninum --> dog and cat • H. nana and diminuta --> rat Tissue ال E.granulosa بقا ليها طابع خاص بس habitat small intestine ثابتة - D.H --> Dog - I.H --> أحنا و ال herbivore (man & herbivore) - Infective stage --> egg - Diagnostic stage --> hydatid cyst larvae - MOI --> Food and water containing dog feaces with eggs
