M. avium - AIDS CAUSES DISEASES OF BIRDS, AEROSOL TRANSMISSION PIGEONS, BIRDS. CAN ALSO BE INTERNALIZED IN FECAL MATTER. OPPORTUNISTIC PATHOGEN OF IMMUNOCOMPROMISED INDIVIDUALS AVIAN TUBERCULOSIS ONLY SEEN IN HUMANS; IMMUNOCOMP. M. avium-intracellulare DO NOT WRESTLE ARMADILLO AFFINITY FOR NERVOUS TISSUE, SLOW GROWING AND GAINS ACCESS TO NERVOUS TISSUE, LEADS TO SENSORY LOSS/ DIGITS AND TIPS. CAN ALSO AFFECT CONNECTIVE TISSUE ACID FAST POSITIVE IRREGULAR RODS M. leprae M. tuberculosis Text 31:43 11/20 Actinomyces sp. Named for colony morphology which is mycelial (actino = ray, myces = fungus). Morphology is mycelial and branched. Aerobic/anaerobic (some strains). Often found naturally occurring in the nasopharynx. CAN ALSO OCCUR IN UPPER RESPIRATORY Streptomyces sp. AERIAL SPORES, PRODUCE ANTIBIOTICS, USUALLY BENIGN IN HUMANS Filamentous, branched cells that form spores. Primarily found in soil; nutritionally versitile. They produce a wide variety of extracellular enzymes, and usually require no growth factors. Many species produce antibiotics. misc. GRAM POSITIVE BACILLI LIKE STREPTOMYCES, ROD LIKE FILMANET, SOIL DWELLING, NORMALLY NOT PATHOGENIC. CAUSES SYSTEMIC INFECTION AND LEADS TO BRAIN DAMAGE.
