Mostly ID Flashcards
What are the main aerobic gram positive bacilli?
Corynebacterium diphtheriae
Listeria monocytogenes
Bacillus anthracis
Clubbing: respiratory causes.
Chronic cyanosis,
lung cancer (bronchial carcinoma and mesothelioma),
suppurative lung disease (e.g. cystic fibrosis, TB abscess),
fibrosing alveolitis.
Clubbing: GI causes
Inflammatory bowel e.g. Crohn’s.
Cirrhosis
Malabsorption e.g. coeliac disease
GI lymphoma.
Clubbing: cardiac causes.
Cyanotic congenital heart disease. Endocarditis Atrial myxoma (a rare cardiac tumour).
Clubbing: rare causes.
Familial
Thyroid acropachy
Unilateral clubbing causes.
Axillary artery aneurysm
brachial arterio-venous malformation.
What are the main gram positive anaerobic bacilli?
Clostridium species
What are the main intracellular bacteria?
Chlamydia, Coxiella, Legionella pneumophilia
What are the main gram -ive cocci?
Neisseria, Moraxella (pneumonia)
What are the the main anaerobic bacteria?
Bacteroides, Helicobacter pylori.
Which are the main dsDNA viruses?
Papovaviruses, adenoviruses, pox viruses, herpes viruses.
Which are the main ssDNA viruses?
Parvovirus
Which are the main dsRNA viruses?
Reoviruses inc. rotavirus
What are the main positive ssRNA viruses?
Picornaviruses (rhinoviruses, enteroviruses inc coxsackie, hep A, echo, enterovirus EV71 and poliovirus)
Coronavirus
Togavirus
What are the main negative ssRNA viruses?
Orthomyxo, paramyxo, arena, rhabdo and bunyavirus
Common use for amoxicillin
Recurrent or severe pneumonia
Common uses for ampicillin
Listeria. Also more active against gram -ive rods than amoxicillin.
Common uses for benzylpenicillin
Meningitis
Common uses for co-amoxiclav
Used for B-lactamase producers, but may contribute to C. diff infections.
Common uses for flucloxicillin
Staphylococci (B-lactamase producing)
Common uses for piperacillin
Very broad spectrum including anaerobes, Pseudomonas, staphs. Reserve for severe infections.
Uses for cephalosporins.
Parenteral pre and post surgery.
UTI, pneumonia and otitis media but NOT FIRST LINE
Uses of gentamicin and amikacin
For serious gram -ive infections. Amikacin has less resistance than gentamycin. Poor against streps and anaerobes, so combine with penicillin/metronidazole.
Clarithromycin and azithromycin uses.
They are macrolides used for S. aureus, strep, mycoplasma, H pylori and chlamydia.
