What organism does gram positive cocci in clusters suggest?
Staphylococcus
What organism does gram positive cocci in chains suggest?
Streptococcus
What type of organism would I use a coagulase test on and what would this show?
Staphylococcus
positive = staph.aureus negative = staph.epidermidis or staph.saprophiticus
What type of organism would I use a haemolysis test on and what would this show
Streptococcus
Partial = alpha haemolysis Complete = beta haemolysis None = non-haemolytic
What type of organism would you do Lancefield group testing for and what would this show
Test = beta haemolytic streptococcus AND non-haemolytic
Group A = S.pyogenes
Group B = S.agalactiae
Group G = S.dysgalactiae
non-haemolytic Group D = S.bovis or enterococcus spp.
Give an example of a group A beta haemolytic streptococcus?
S.pyogenes
Give an example of a group B beta haemolytic streptococcus?
S.agalactiae
Give an example of a group G beta haemolytic streptococcus?
S.dysgalactiae
Give 2 examples of group D non-haemolytic streptococcus?
S.bovis
Enterococcus spp.
Give an example of a coagulase positive staphylococcus?
Staphylococcus aureus
Give 2 examples of coagulase negative staphylococcus?
Staph.epidermidis
Staphy.saprophiticus
On what would you use an optocin test and what would this show?
Test = alpha haemolytic streptococcus
Sensitive = s.pneumoniae Resistant = s.viridans
What test would you do on a gram negative bacillus and what would this show?
Test = MacConkey or CLED or XLD
Lactose fermenting = E.coli, klebsiella
Non-lactose fermenting = salmonella, shigella, pseudomonas, proteus
On what type of organism would you use on oxidase test and what would this show?
Test = non-lactose fermenting gram negative bacilli
Positive = peudomonas Negative = proteus, shigella, salmonella
Give 2 examples of lactose fermenting gram negative bacilli:
E.coli
Klebsiella
Give 3 examples of oxidase negative non-lactose fermenting gram negative bacilli:
Salmonella
Shigella
Proteus
Give 4 examples of non-lactose fermenting gram negative bacilli:
Salmonella
Shigella
Proteus
Pseudomonas
