Neisseria meningitidis

The objective of this lab was to isolate and identify an unknown Gram positive and Gram negative bacteria through the use of various microbiological techniques. The identification of the genus and species for the unknown culture should be obtained based on the characteristics for Gram positive and Gram negative bacteria. Bacteria are prokaryotic microorganisms that lack a nucleus and therefore all its genetic information is stored in the cytoplasm of the cell. The bacterial cell envelope…

The protective membranes that surround the brain and spinal cord are called the meninges. The meninges consist of three layers, the dura mater,…

Normal flora is the colonisation of human tissues by a diverse mixture of microorganisms. This colonisation begins at birth with pioneer species, depending on physiochemical factors. The normal flora inhibits the skin, oral cavity, upper respiratory tract, gastrointestinal tract, urogenital and conjunctival membranes. They are commensal bacteria; getting shelter and nourishment from the host without causing harm (Gould, 2012). To a healthy individual, most normal flora is harmless, however some…

Human papillomavirus (HPV) 1. Characteristics of the disease Human papilloma virus (HPV) infections produce epithelial lesions of non-genital and genital skin as well as mucous membranes. HPV infections are common throughout the world. Although most HPV infections cause no symptoms, persistent genital HPV infection can lead to cervical cancer in women, the second most common cancer in women. The ability of HPV to cause cervical cancer was first shown in the 1970s for epidermodysplasia…
