- types of bacteria: BVFP
- bacterial
- B for bacteria
- prokaryotic- no enclosed nucleus, so the bacteria is a PRO at CARRYING out infection
- shapes of bacteria
- unicellular- spherical (cocci)- "uni"- UNICYCLE like a bicycle wheel is round (spherical), cocci- circular letters C, O
- rodlike- BACILLI spiral- SPIRILLA, spiral legs coming out of bacteria comma shaped- VIBRIOS corkscrew shaped- spirochete- (moves quickly, like cork from a bottle)
- reproduce asexually- 1, 2, 4, infection knocks on the door, 8, feelin' feverish, mate, 16, 32, what do i do?
- reside in nature- exposure to the environment, nature
- invasion- bacteria are BAD- they like to fight with the body's natural defence mechanisms- phagocytes, antibodies
- bacteria can produce carbohydrate or protein shields of defence to protect themselves against phagocytosis
- Exotoxins: EXIT proteins released during bacterial growth – a poisonous substance
- Endotoxins: ENTER (lipopolysaccharides [LPS]) – released during lysis (destruction) of the bacteria
- bacteria can produce carbohydrate or protein shields of defence to protect themselves against phagocytosis
- invasion- bacteria are BAD- they like to fight with the body's natural defence mechanisms- phagocytes, antibodies
- can infect any area of the body- any part of you, i can do too!
- viral
- simple micro organism VIRON- simple nucleic acid shell on the viral organism. RNA and DNA, viral diseases are the most common amongst humans, viral herpes, coldsores, oral herpes, AIDS, HIV
- 1. Attachment to target cell 2. Penetration 3. Uncoating (release of viral nucleic acid) 4. Replication 5. Assembly (formation new virons) 6. Release APURAR- attach, penetrate, uncoat, replicate, assembly, release
- rapid division- short incubation periods like norovirus, not long before you catch V&D until you feel symptoms!
- variation- flu - undergoes frequent antigen shifts; some viruses have multiple stable antigenic serotypes - person recovers from one serotype but not otherse.g. common cold
- transmission – one infected individual to an
uninfected individual: aerosols of respiratory
fluids, contact infected blood, sexual contact
- here comes the virus transport! uses the human body like a human train station
- simple micro organism VIRON- simple nucleic acid shell on the viral organism. RNA and DNA, viral diseases are the most common amongst humans, viral herpes, coldsores, oral herpes, AIDS, HIV
- fungal
- simple organism lacking green chlorophyll- HOWEVER fungal infection on nails can appear GREEN
- Eukaryotic; thick rigid cell walls & can form a
variety of complex structures, e.g. fungal nail infection presents as thick, crusted, discoloured
- dermatophytes- DERMA like on the skin, DERMIS, itching is intense- cracking, like ATHLETE FOOT
- fungal pedis- ped (foot) fungal capitis (cap, head- wearing a CAP on your head)
- Protection against phagocytosis – encapsulated yeast cells more resistant – block recognition by macrophages
- Immune suppression – stimulate the production of immunosuppressive cytokines
- Candida albicans – found in the mouth, GI tract and vagina- treatment using CANDESTEN Changes in pH & use of antibiotics can permit rapid proliferation
- fungal pedis- ped (foot) fungal capitis (cap, head- wearing a CAP on your head)
- dermatophytes- DERMA like on the skin, DERMIS, itching is intense- cracking, like ATHLETE FOOT
- Eukaryotic; thick rigid cell walls & can form a
variety of complex structures, e.g. fungal nail infection presents as thick, crusted, discoloured
- moulds and yeast, MY
- simple organism lacking green chlorophyll- HOWEVER fungal infection on nails can appear GREEN
- parasitic and protozoal
- any living thing that lives in or on another living organism
- Parasitic worms (helminths) e.g hookworm
&roundworm; flukes e.g. liver or lung fluke; and
tapeworms- HELMINTHS: if you think about worms in your poor cat or dog (zoonotic), they give your pet HELL!
- Risk factors – weakened immunity; lack clean drinking water; contact with soil containing infected animal or human faeces; live or travel in tropical, subtropical regions 4. Parasitic & protozoal infection-
- RAINFORESTS, TROPICAL CLIMATE, DEVELOPING COUNTRIES, MOSQUITOES, POOR WATER/FOOD HYGIENE
- bacterial
