What bacteria that causes Vaginosis is gram + but looks like a Gram - and the increased prevalence of the bacteria indicates BV but its not the sole etiologic agent? |
Gardnerella Vaginalis |
|
|
What two bacteria cause Vaginosis they are gram + and are thought to maintain acid pH by metabolizing glucose? |
1.Lactobacillus crispatus 2.L. jensenii |
|
|
What bacteria replaces lactobacillus in BV in females? |
G. Vaginalis |
|
|
What bacteria that has the highest incidence of BV in women and show no gram reaction? |
Mycoplasma hominis |
|
|
Name all Facultative anaerobes that cause BV |
1. G. vaginalis 2.LActobacillus 3.L. jensenii 4.Mycoplasma hominis |
|
|
This bacteria is an obligate anaerobe (G+), show a very high incidence of BV and is used in the morphologic diagnosis of BV? |
Mobilincus |
|
|
This bacteria is an obligate anaerobe (G-) and is also seen in biofilms in the gum line? |
Fusobacterium |
|
|
Describe some of the ways lactobacillus prevents the colonization and overgrowth of less desirable vaginal flora? |
1.Hydrogen peroxide production. Anaerobic bacteria lack catalase peroxidase and can't eliminate Peroxide 2.Lactid acid. Creates low pH maintaining a higher oxi-redux potential inhibiting anaerobes growth |
|
|
True or false The ability (adherence) of Mobilincus and G vaginalis increases with increased pH |
True |
|
|
T/F Increase in endotoxin, collagenases and proteases along with amines associated with BV and malic acid production by Mobilincus can cause irritation of the mucous membrames |
True |
|
|
What is the sexual association of BV since it is not sexually transmitted? |
Semen and saliva change pH |
|
|
What are some clinical dx? |
1. vaginal fluid with a pH of greater than 4.5 2.Homogenous adherent discharge 3. Fishy odor( due to metabolic byproducts)
|
|
|
What are some of the lab diagnosis? |
CLue cells on a saline wet mount
|
|
|
What are clue cells? |
Vaginal epithelial cells with so many gardnerella that its borders are obscure |
|
|
what are some of the complications associated with BV? |
Pelvic inflammatory disease Pre term birth Premature rupture of membranes Post partum endometris cellulitis |
|
|
What medications can we give to someone suffering from BV. |
1.Metronidazole(blocks nitro reductase) 2.Clindamycin 3.Probiotics |
|
|
Describe acute prostitis |
Bacterial infection, usually from intestinal tract |
|
|
Describe chronic prostitis |
mixed population of bacterial biofilms |
|
|
What are some of the symptoms of prostatitis? |
Painful ejaculation or urination frequent urge to urinate blood in urine |
