Haemophilus WHO AM I?
I require X and V factor, I do not lyse RBCS on horse blood, I am a tiny, pleomorphic GNCB and am a known respiratory pathogen!
a pink bacillus that appears small and somewhat coccoid in shape
What is a GNCB?
growth around the XV disk
no growth around the X disk
no growth around the V disk
(cannot lyse horse blood)
Haemphilus influenzae
I ferment glucose, am oxidase positive and catalase negative. I am pretty well known for causing bone, blood, joint infections and arthritis in young children
Who is Kingella ?
Catalase negative, GPC in pairs and chains, PYR positive, bacitracin susceptible
What is Streptococcus pyogenes?
class of antibiotics that are cell wall synthesis inhibitors, treat Staph, N. gonorhoeae and Group A Strep infections and includes Penicillin G, Aminopenicillins, Ticarcillin and Piperacillin.
Some orgs produce enzyme that may inactivate them.
What are B-lactams?
I require hemin, cause painful genital ulcers and sometimes I tag along with syphilis....eeek!
Who is Haemophilus ducreyi?
Haemophilus influenzae
What is tiny, GNCB/GNR?
Haemophilus species expected reactions for oxidase, catalase, nitrate reduction
oxidase positive, catalase positive, nitrate reducer
I am needy. I gotta have hemin and NAD for growth. I am the most pathogenic strain. I am so gnarly, they had to make a vaccine to try and stop me!
mwah ha ha!
Who is Haemophilus influenzae type B?
GNDC, catalase positive, oxidase positive, CTA glucose positive, maltose, lactose and sucrose negative
What is Neisseria gonorhoeae?
Antibiotic that inhibits RNA synthesis and treats Mycobacterium tuberculosis
What is Rifampin?
I am oxidase positive, require V factor, lyse horse RBCs, and am rarely pathogenic.
Who is Haemophilus parahaemolyticus?
Short rods with squared ends that may resist decolorization
Who is Kingella?
pinpoint growth of Haemophilus influenzae around beta hemolytic Staphylococcus aureus
Satellitism
I am normally found in the upper respiratory tract but can cause endocarditis, especially those with aortic heart defect. I am oxidase positive but catalase negative, which is useful in identifying me
Cardiobacterium
GPC in clusters, catalase positive, Staphaurex positive, resistant to cefoxitin
What is methicillin-resistant Staphylococcus aureus?
IV administration
Glycopeptide
Peak and trough levels
What is Vancomycin?
I require both hemin and NAD, I destroy horse blood cells in the media and may resemble Group A Strep. I also hang around the throat and upper respiratory tract.
Who is Haemophilus haemolyticus?
GNR that form rosettes in yeast extract
What is Cardiobacterium?
Haemophilus antigens bind with fluorescent-tagged antibodies (if present)
Fluorescent antibody tests
I like to cause infections after human bites or if you don't brush your teeth. I can grow on blood agar and may pit it. They say I smell like sodium hypochlorite...whatevs
Eikenella corrodens
short, pleomorphic GPR/GVR that is a common cause of bacterial vaginosis
What is Gardnerella vaginalis?
Enzyme that is commonly seen in enteric organisms that cause them to be resistant to b-lactam drugs and 3rd generation cephalosporins
What is an Extended-spectrum beta lactamase?
I need nicotinamide adenine dinucleotide, produce tan colonies on chocolate agar and can make your ear hurt.
Who is Haemophilus parainfluenzae?
tiny GNCB that resemble "school of fish," when seen from direct specimen smears of genital lesions
What is Haemophilus ducreyi?
rapid test performed on cerebral spinal fluid to diagnose meningitis caused by Haemophilus influenzae
Haemophilus Latex particle agglutination test (LPA)
You can find me hanging out in mouths. I love carbs! While I am not too pathogenic, I have been known to cause endocarditis, periodontitis and bone and joint infections. hehe
Who is Aggregatibacter aphrophilus?
aerobic, spore producing, GPR that produces non-hemolytic "medusa head" colonies and may be used in bioterrorism
What is Bacillus anthracis?
An advanced beta lactam antibiotic that is effective against MRSA and penicillin-resistant Streptococcal infections
What is Ceftaroline?
