Gardnerella vaginalis started a controversy due to different interpretations of its clinical significance, taxonomic position, and Gram stain reaction. The organism was first named Haemophilus vaginalis. However, it lacked some of the characteristics the Haemophilus species required. It was then referred to as Corynebacterium vaginale. It was later changed to Gardnerella vaginalis when a new genus was necessary (Catlin, 1992). This paper will focus on the characteristics of G. vaginalis and how it
Trichomonas Vaginalis T. vaginalis is a pear-shaped organism that moves itself with four whip-like flagellas that protrude from its front end. A fifth flagellum attached to a flowing membrane that extends rearward. T. vaginalis is a non civilized eukaryotic organism that is in most respects similar to other eukaryotes, but its energy metabolism bears a stronger resemblance to that of anaerobic bacteria. Trichomoniasis is a very common sexually transmitted disease (STD) that is caused by infection
was for biology specifically microbiology. In 1978 Alderete received his P.H.D. in microbiology form the University of Kansas, Lawrence. Alderete focused his research on one of the world’s most commonly sexually transmitted diseases trichomonas vaginalis, commonly known as trichomoniasis or trich. This protozoal STD manifests itself in a variety of ways including genital Itching, burning, redness, sore and swollen genitals, a frequent urge to urinate, burning when urinating, and genital discharge

Microbial biofilms are populations of microorganisms that are concentrated at an interface and typically surrounded by an extra cellular polymeric slime matrix. Biofilms can form on both solid surfaces such as teeth or dental implants and soft tissue such as gums and cheek walls. Microbial biofilms cause dental caries and periodontal infections. Normal host immune defenses do no remove microbial biofilms and they are also resistant to the effects of antimicrobial agents. Biofilm moves through
Introduction Bacterial vaginosis is known to be the most common cause of abnormal vaginal discharge in women of childbearing age (Hay, 2010). Bacterial vaginosis is the result of the substitution of normal vaginal lactobacilli with anaerobic bacteria Gardnerella vaginalis and Prevotella, Peptostreptococcus and Bacteroides spp., which will result loss of the normal vaginal acidity (Turovskiy, Sutyak Noll, & Chikindas, 2010). Bacterial vaginosis is the main trigger of vaginal discharge or malodor in women (Hainer
