TYPES OF UTIs : If bacteria only in bladder only, called cystitis , a lower UTI. If kidneys are infected, called pyelonephritis (say PIE-el-o-ne- fright-us), an upper UTI. Q: Is penicillin usually prescribed for UTI infections? Images: E.coli with fimbria , National Library of Science; Gram stain E. coli , T. Port; MacConkey’s , T.

Lactose Fermentation MacConkey’s agar helps us identify different types of Gram negative bacteria. There is lactose in the medium that the bacteria can eat, and a pH sensitive dye that turns pink, if they “poop out” waste from breaking down lactose. Lac+ genera include E. coli, Enterobacter, and Klebsiella. Lac- genera include Salmonella, Shigella, & Proteus. Image: MacConkey’s agar, T.

GRAM NEGATIVE Microaerophilic, Acidophile Helically shaped Never normal flora Robin Warran & Barry Marshall identified H. pylori in 1982, and discovered link between H. pylori and ulcers. H. pylori virulence factors: - Make proteins that inhibit acid production - Flagella propel through stomach lining to epithelial cells - Have adhesins - Make enzymes to inhibit phagocytosis What Is an Ulcer? A sore or hole in lining of the stomach or duodenum (the first part of the small intestine). Not caused by stress or eating spicy food, but these factors can make ulcers worse. Symptoms: Most common ulcer symptom is gnawing or burning pain in the abdomen between the breastbone and the belly button. Incidence: Many people have H. pylori infection, but most infected people, do not develop ulcers.

GRAM NEGATIVE (but difficult to Gram stain properly). Aerobe & facultative anaerobe H. influenzae first isolated during influenza pandemic of 1890, and mistakenly thought to be cause of deadly influenza. Q: What type of microbe causes influenza? ___________ microbe. Usually grown on chocolate blood agar because needs both hemin (factor X) and NAD (factor V)to grow. Encapsulated & Unencapsulted In 1930, two major categories of H. influenzae were defined: unencapsulated & encapsulated. Q: What does it mean for a bacterium to be encapsulated? Shape Shape of H. influenzae varies: encapsulated typically coccobacilli, unencapsulated pleiomorphic. Disease Unencapsulated strains commonly present on mucous membranes as normal flora , but can become opportunistic, causing ear infections (otitis media), eye infections (conjunctivitis), and sinusitis in children, and is associated with pneumonia.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
