<p>Abbreviation key for photographs</p><p>Organism names: these are abbreviated so the genus and species names are shortened but recognizable. Because many genus names start with the same letter (e.g., Salmonella, Shigella, Staphylococcus, Streptococcus, Serratia, etc.) multiple letters are included to make the names recognizable and to allow proper sorting in the computer.</p><p>7h11 Middlebrook 7H11 agar 10exp3 10 exponent 3=1,000 10exp4 10 exponent 4=10,000 10exp5 10 exponent 5-100,000 absc abscess af (or afs) acid fast stain (Ziehl-Neelsen, Fite, Kinyoun, etc) aura auramine O fluorescent stain for mycobacteria bap blood agar plate bbe bacteroides bile esculin agar bc blood culture bx biopsy cfu colony forming units cholesys cholesystostomy csf cerebrospinal fluid cytospin cytocentrifuge concentration of cells, organisms, and debri dc diplococci dischg discharge emb eosin-methylene blue agar plate f female; 37f = 37-year-old female; m=male few few fna fine needle aspiration gas group A streptococci gbs group B streptococci gcs group C streptococci gen fl genital flora gf genital flora glu glucose gn gram-negative gncb gram-negative coccobacilli gndc gram-negative diplococci gnicdc gram-negative intracellular diplococci gnr gram-negative rods gpcc gram-positive cocci in clusters suggesting staphylococci gpcpc gram-positive cocci in pairs and chains suggestion streptococci gpcpclus gram-positive cocci in clusters suggesting staphylococci gpr gram-positive rods grp group gs gram stain he Hektoen enteric agar kia Kliglers iron agar kiny Kinyoun acid fast stain lac lactose lite (back lite) lighted from the back lkv laked blood kanamycin vancomycin agar m male; 37m=37-year=old male; f=female mac MacConkey agar plate man mannose mod moderate num numerous on oral nasal flora paf partial acid-fast stain per ml per milliliter as in cfu/ml periton peritoneal pt patient followed by a number & letter, i.e. pt1a is a case sc subculture pmn polymorphonuclear cells sel f selenite F broth sp species spu sputum strep select Strep Select agar with neomycin & Polymyxin B tcbs thiosulfate-citrate-bile salt-sucrose agar plate TSI triple sugar iron agar tube (with slant over butt) tis tissue tm Thayer-Martin medium with Trimethoprim, Colistin, Anisomycin & Vancomycin unk unknown cell type ure urethra (urethral) urin urine urms urine midstream culture w with xld xylose-lysine-desoxycholate agar plate yst yeasts zn Ziehl-Neelsen acid fast stain</p>
