الحمد لله على السلامة شباب اخر الاحزان ان شاء الله

هذا مهم انتبهوا عليه ادخلوا للقناة وشوفوا الصورتين الي فوك هاي الصورة والاربع صور الي جواها

IMViC test for Klebsiella spp.

فالمفروض هذا الاختراع بقى هو مال fecal occult blood test

شباب هذني حسب كلام د.سرمد يكول اذا جني نكتب Immunochromatography Assay

شباب هنا Taenia saginata هم نكدر نستخدم scotch tape method بس هية اهم وحدة لازم تتذكورها بالscotch tape هي الpinworm الي هية E. vermicularis

Q1/ Identify Q2/ What is the infective stage?
