MCB 2010 L Organism Classification

• Domain Archaea • Includes the extremophile bacteria • Not looking at examples in lab

Domain Bacteria • Subkingdom Cyanobacteria – “blue-green algae” (but not algae!) – Oscillatoria • Subkingdom Bacteria – Next slide

Domain Bacteria Subkingdom Bacteria • • • Pseudomonas aeruginosa – Gram negative bacillus Can cause opportunistic infections On you organism classification guide, if it says whether it’s Gram+ or Gramand/or shape, know that

Domain Bacteria Subkingdom Bacteria • Bacillus subtilis – Gram positive bacillus, notice the spores

Domain Bacteria Subkingdom Bacteria • • • Vibrio cholerae – Gram negative curved rod Disease of digestive system Produces enterotoxin, Shiga toxin

Domain Bacteria Subkingdom Bacteria • • • Neisseria gonorrheae – Gram negative diplococcus Sexually transmitted disease Has capsule

Domain Bacteria Subkingdom Bacteria • • Streptococcus pneumoniae – Gram positive coccus, forms pairs or short chains Pneumococcal pneumonia

Domain Bacteria Subkingdom Bacteria • • • Streptococcus pyogenes – Gram positive coccus Group A strep Can cause necrotizing faciitis

Domain Bacteria Subkingdom Bacteria • Staphylococcus epidermidis – Gram positive coccus

Domain Bacteria Subkingdom Bacteria • • Borrellia burgdorferi – Gram negative spirochete Lyme disease

Domain Eukarya • Kingdom Protista – Subkingdom Protozoa • Phylum Sarcomastigophora • Phylum Apicomplexa • Kingdom Fungi – – Division (Phylum) Zygomycota Division (Phylum) Ascomycota Division (Phylum) Basidiomycota Deuteromycota • Kingdom Animalia – Phylum Platyhelminthes • Class Cestoda • Class Trematoda – Phylum Nematoda

Domain Eukarya Kingdom Protista Subkingdom Protozoa • Phylum Sarcomastigophora – Entamoeba histolytica • Amebic dysentary – Trypanosoma gambiense • African sleeping sickness – Giardia lamblia • Bever fever • Phylum Apicomplexa – Plasmodium • Malaria

Domain Eukarya Kingdom Fungi Division Zygomycota • • Black bread molds Rhizopus stolonifera – Sexual reproduction via zygospores formed by fusing of the haploid hyphae – Asexual reproduction by haploid spores formed in sporangia

Domain Eukarya Kingdom Fungi Division Ascomycota • Sac fungi and yeast – – Saccharomyces - yeast Peziza Aspergillus Penicillium – Sexual reproduction by haploid ascospores formed in asci at tips of hyphae which might be organized in fruiting body (ascocarp) – Haploid nuclei fuse then undergo meiosis followed by 2 mitotic division to produce 8 ascospores

Domain Eukarya Kingdom Fungi Division Basidiomycota • Club Fungi – “mushrooms” • Coprinus – basidiocarp

Domain Eukarya Kingdom Animalia Phylum Platyhelminthes • Class Cestoda – Taenia pisiformis • tapeworm • __________ • Class Trematoda – Clinorchis sinensis – Fasciola hepatica • Liver fluke

Domain Eukarya Kingdom Animalia Phylum Nematoda • Necator americanus – hookworm • Trichinella spiralis • Enterobius vermicularis – pinworm

• Ascaris lumbroides
