• GRAPELIKE ODOR & Blueish/Green pigment _{common cause of nosocomial infections}
• multidrug resistant
• resistant to soaps and dyes
• Opportunistic
• Freq contaminates of Ventilators, IV solutions, anesthesia equipment
• Produces Oxidase and Catalase
• Gram Negative, Bacilli, aerobic
• soil and water

• opportunistic
• Gram Negative
• Aerobic Rods
• soil/water
• Oxidase +

• drug resistant
• active biodegradation of a variety of substances
• opportunistic in resp tract, urinary tract, occasionally skin infections

• gram negative, aerobic rods
• Generally acquired thru penetrating injury or inhalation
• Causes wound infection, bronchitis, pneumonia and septicemia

• Gram Negative Bacilli
• Opportunistic
• Aerobic
• soil/water
• Oxidase +

• Extremely Resistant {must treat with combo of antimicrobials}
• Nosocomial & Community infections
• Gram Negative, aerobic rods, opportunistic

• contaminant of dialysis & resp equipment
• Must isolate
• Multi Drug Resistant
• FORMS BIOFILM

Gram Negative, Aerobic rods

• tiny Gram Negative coccobacilli
• TEST Aggulatination Titer Test

treat with combo tetracycline and rifampin or streptomycin

• Potential BioWeapon
• zoonosis - 2 types cattle and pig

• Cattle
• Potential BioWeapon
• causes malta fever, undulant fever, and Bang Disease

• Gram Negative
• treat with combo Tetracycline & rifampin or streptmycin

• Pig
• transmitted to humans by animals
• causes fluctuating fever that lasts for weeks to year

• Gram Negative
• Treat with combo tetracycline and rifampin or streptomycin

• causes tularemia
• carried by RABBITS
• Treated with Gentamycin or Tetratcycline
• Potential BioWeapon
• Vacc Available

GramNegative Bacilli

• whooping cough
• Vacc DTaP

Gram Negative Bacilli

• primarily in soil and water
• May become Normal Flora

they are both gram negative bacilli, zoonotic pathogens

• Brucella is cattle or pigs
• Francisella rabbits

both are gram negative Bacilli and opportunistic pathogens

mainly human pathogens

also both are gram negative bacilli

• prevalent in males over 50
• Legionaires or Pontiac Disease
• TREAT with Azithromyicn

• Enterics (divided into Coliforms and noncoliforms)
• most common cause of diarrhea thru entrotoxins
• BBL tube used for DX
• Complex antigens contribute to pathogenicity and trigger immune response (H,K,O)
• Facultative Anaerobic (grows best in air), Gram Negative

• most prevalent enteric bacillus
• coliform count is indicator to fecal contamination in water
• most common Aerobic, nonfastidious, bacterium in the gut
•  gram negative

• opportunistic coliform
• normal inhabitant of the resp tract
• causes nosocomial pneumonia, meningitis, bacteremia, wound infections and UTI

• opportunistic coliform
• UTIs, surgical wounds

• Klebsiella pneumoniae - normal inhab or resp tract
• Enterobacter -UTI, surgical wounds
• Citrobacter- UTI, bacteremia
• Serratia marcescens - produces red pigment

• opportunistic coliform
• UTI, bacteremia

• opportunistic coliform
• produces red pigment
• causes pneumonia, burn and wound infections, septicemia

• Proteus (usually harmless)
• Salmonella and Shigella (human host)

• Typhoid Fever
• human host
• Treat with chloramphenicol or sulfatrimethoprim

gram negative bacilli

1,000 different types based on variation of antigens O,H,V

Both salmonella are flagellated and can survive outside the host and are resistant to chemical and dyes

• Human parasites
• incapacitating dysentery
• invades large intestine but does not perforate intestine or invade blood
• Treat fluid replacement and Cipro and Sulfatrimethoprim
