pathogenic in nature, invades tissues, has endotoxnis 

Virus, DS DNA

Causes chicken pox/shingles

spiked enveloped polyheral ecapsulated virus

chicken pox: acute, shingles: latent

immunity can be conffered through vaccination  

Gram negative, not readily dyed

leading cause of infectios blindness, body makes eyelashes turn inward  

Bacteria

causes meningitis

1st organism to have its entire genome sequneced

nearly abolished in US ince dev. of vaccince

75% of healthy adults and kids carry it 

Basidiomycota

Causes cyrptococcosis

only communicable by inhaling bird feces, in immunocomprimised people (AIDS) 

causes Sepsis

Blue-Green pigment

Opportunistic and nosocomial pathogen

produces biofilms  

G weird bacteria, causes TB

waxy lipid cell wall increaing virulence

slow growth, necessary to treat with diff. antibiotics

a tubercule grows slowly in the lungs  

smallpox,

DS DNA

2 forms: variola major/minor

1st disease w/ artificial immunity 

50% of common colds

virucidal facial tissues lowers risk of transmission

only 1 rhinovirus needed to cause disease 

2nd most common STD

contains Fimbrae and pilli

several antibiotics can cure it 

DS DNA virus

Transmitted through sexual contact

involves latency periods 

causes tetanus

older samples appear gram-

gram stain looks like tennis racket

2 neurotoxins: tetanosporin, and tetanolysin 

causes Malaria

unique reproductive cycle: has deffinative and intermidiate hosts

Prevention is key using DEET

heterozygous...anemia  

Gram+ Rod

Causes Anthrax

Produces 2 "type 3" exotoxins

has ability to produce endospores

3 forms of infection: cutaneous, inhalational, gastrointesinal 

4 strains of the virus

causes Purpura (bleeding of the skin)

studied in BSL-4 (biological safety level 4)

mortality rate of 50-90% 

DS DNA

causes Mono

infects 2 types of cells, salivary glands, lyphocytes

children are asymptomatic

95% are infected and are carriers for life 

ascymycota: Sac like fungus

Causes PJP (pneumonia) #1 cause of death in AIDs Pts

 Obligate aerobe

Ascomycota Fungus

causes Valley fever

single cell hyphae w/ barrel shaped arthrodicia

releases endospored in tissue

causes coccidiomycosis true pathogenic systemic humal fungal disease known 

Gram- Rod

Facultative anerobe

motile bacterium

produces 2 enterotoxins causing symptoms  

SS +sense RNA

penetrates VLDL's of liver

Detectable wtihin short time of transmission 

Gram- spirochete

causes syphillus

moves in corkscrew motion

not sucesfully cultured on artificial meia or tissue culture

has 3 subspecies  

causes measles

SS RNA

Vacine introduced in 1963

contracted through Resp. system and spread through skin 

causes hymolitic uriatic syndrome

inability to ferment sorbitol

to be infected, the organism must be injested 

causes the plauge

Resevoir: rodents

looked at as possible biological warfare agent

tetracycline, fluroquilones, gentenamycin, and doxycycline are used in combination for treatment 

Bacteria

causes group A strep infections

causes mild infections such as pharyngitis

has a carb. capsule to protect against dessication 

Causes 22,000,000 cases of typhoid fever

over 2,000 serovars identified

resistant to 5 known antibiotics  

causes PAM primary amoebic menin.

3 forms ameobic flagella and cyst

found in warm fresh water around the world
