Parasites, Fungi, NF

Animalia and Protozoa parasites, fungi, normal flora bacteria

Entamoeba hisotlytica intestinal protozoa, world-wide, fecal-oral transmission, causes ulcers in colon and liver abscesses, (have pseudopods that damage cells and ingest RBC)
Cyrptosporidium intestinal protozoa, world-wide, contaminating water or zoonotic distribution (mammals), burrows in intestinal epithelium
Trichomonas Vaginalis UG protozoa, world-wide (greater in females), sexual contact transmission, no cyst stage
Plasmodium Blood and Tissue protozoa, tropics/sub-tropics, mosquito transmission, damage RBC to cause anemia
Toxoplasma gondii Blood and Tissue protozoa, world-wide, zoonotic (cats) and ingestion (mm infected with pseudocysts) transmission, able to cross placenta
Hemilinths broad class of worms with elaborate attachments, no circulatory system, secretion of enzymes that injury tissue, ability to alter antigenic properties
Ascaris lumbricoides Nematode (round-worm), world-wide, fecal-food contamination transmission, moves from GI - Blood - Lung - GI
Wuscheria bancrofti Nematode (round-worm), Tropic/Sub-tropic, mosquito transmission, elephantitis
Taenia Saginata Cestode (tapeworm), world-wide, contaminated raw beef ingestion
Schistosomes Trematode (fluke), Afric/Asia/Lt. America, transmitted in fresh water by snail host, lives in veins, gets trapped in urinary tract, intestines and liver to cause inflammation
Pityriasis Versicolor superficial mycoses in tropics/tempearte climates. Example = M. furfur (lipophilic yeast part of skin NF)
Tinea Nigra superficial mycoses, melanin-producing dimorphic fungi found in the soil of tropics
Black and White Piedra superficial mycoses that forms black and white nodules on the hair shaft
Ringworm cutaneous mycoses (keratinase producing fungi on skin/hair/nails), named tinea [body area infected]
Sporotichosis subcutaneous mycoses (chronic, localized with no human-to-human transmission), caused by thorn pricks, cause nodules and ulcers that drain along lymphatics
Histoplasmosis Dimorphic fungi found in Ohio/Mississippi Valley - asymptomatic, granulomas
Blastomycosis Dimorphic fungi found in Ohio/Mississippi/Arkansas/Missouri Valley that is similar to Histoplasmosis (mimics TB) but is symptomatic
Coccidiomycosis Dimorphic fungi in SW US, Mexico, and S. America. Asymptomatic, but 50% mortality if untreated
Paracoccidiomycosis Dimorphic fungi in central and south america that is often asymptomatic but can cause oral/nasal/facial lesions and infected lymph nodes
Candida Opportunistic fungi on skin and mucosa, that can overgrow flora to cause thrush and even spread to blood to cause a systemic infection
Pneumocystis carinii Opportunistic fungi part of normal lung flora that can cause pneumonia in immunocompromised
Cryptococcus neoformans Opportunistic fungi in soil and bird droppings that forms capsules to avoid phagocytosis
Aspergillus Opportunistic fungi in soil and plants that forms spores that are aerolized during building rennovations
Zygomycetes Opportunistic fungi that is a ubiquitous saprophyte that infects the nose, sinuses, eyes, cranial bones, and brain
Staph. epidermitis, Corynebacterium, Proionbacterium Acnes common organism on the skin
Staph. Aureus common organism in nares of nose
Strep. pneumoniae, Neisseria meningitis, Haemophilus influenzae common organisms in nasopharynx
Strep. mutans common organism in mouth that causes tooth decay by converting sucrose to fructose and glucose
Anaerobes in mouth found in gingival pockets - cause periodontal disease
Bacteroides, Clostridium, Entercoccus, Candidia, E. Coli common organisms in the colon
