Medical Bugs

Transmitted by intercourse and oral sex and from mother to daughter. Primary infection: Chancre at site of infection Secondary: system symptoms with rash on Palms and soles of feet

Bacteria, end-hook allows for better attachment to host, found in tropical and temperate regions. Often in Kidey tubules. Transmission from urine of infected animal or enviroment

Tick born infection common in North America Red rash with consitutional symptoms chronic arthiritis and CNS effects

Ticks and lice used as vector for transmission. High fever (up to 43oC) for a couple days followed by hypotension and drop in temp. Peripheral blood smear with Gemsa or Wright staining to confirm diagnosis

Tropical areas of Africa, Asia, S. America. High lipid content Relies on host for fatty acids, nucleotides and amino acids. Direct person-to- person contact (through break in the skin); children under 15 more likelytobeaffected. 1o stage: lesion at inoculation site after 3 wk incubation 2o stage: widespread dissemination through blood results in multiple skin lesions Latentstage:symptomsusuallyabsent for up to 5 y; relapse may occur 3o: bone, joint and soft tissue lesions and deformities may occur

Food poisoning/intoxication, toxin mediated skin syndrome. Hospital acquired infection. oFten resistant to many antibiotics. Typically infects wounds or catherters. Many people are carriers. Coagulase +ve Gram +ve, coccus.

Coagulase -ve, gram +ve coccus. Opportunistic infection often found in blood. Part of the normal flora of skin. Forms biofilms on plastic. Can cause endocarditis peritonitis bacterimia

Normal GI flora, coagluase -ve gram +ve coccus. 2nd most common UTI in females. Surface adherens facilitate attachment

Coagluase -ve gram +ve coccus part of normal skin flora can cause skin or soft tissue infections as well as endocarditis

Coagluase -ve gram +ve coccus part of normal skin flora can cause skin or soft tissue infections as well as wound infections

Scarlet Fever, pharyngitis necrotizing fascitites rheumatic fever. Direct person to person transmission.

Gram +ve bacteria belonging to the lactic acid bacteria group. Coccus Neonates pheumonia sepsis and meningtis. Droplet transmission

Gram +ve bacteria belonging to the lactic acid bacteria group. Pneumonia Meningitis and Otitis media. droplet transmission.

Font Size... Font Family... Gram -ve bacillus Aerobic. Commensal bacteria in large intestine motile with peritrichous flagellae. Fecal-oral transmission. Causes Gastroenteritisi and heat stable/labile enterotoxin which prvents water absorption in intestinal cells. Causes 90% of UTIs. Causes neonatal menintisis

Gram -ve facultative anaerobe. transmitted in contaminated food or water. produces diarrhoea abdomonal pain and fever. Infects small bowel and proximal large bowel. Can invade to the basolateral side and replciate within macrophages and avoid innate immune response and form granulomas and microabcesses
