The Gram stain showed Gram-negative diplococci. Intravenous ceftriaxone and cloxacillin treatment was begun, pending culture results.
Enterococci are Gram-positive cocci that often occur in pairs (diplococci) or short chains, and are difficult to distinguish from streptococci based on physical characteristics.
gonorrhoeae were identified based on colonial morphology (growth of typical colonies), Gram stain (Gram-negative intracellular diplococci in stained smears), and oxidase reaction (oxidase-positive).
Other tests like Gram's staining (gram negative intracellular diplococci) and culture for Neisseria gonorrhoeae; KOH examination for candidiasis (budding yeast like structure and or pseudo-hyphae), Tzanck smear (multinucleated giant cells) and serological HSV-2 IgM and IgG for herpes progenitalis were also performed to help in the diagnosis of different STIs.
Caption: A gram stain of a urethral exudate containing Neisseria gonorrhoeae from a patient with gonococcal urethritis shows typical intracellular gram-negative diplococci and pleomorphic extracellular gram-negative organisms, diagnostic for gonococcal urethritis.
Gram-stain was performed to determine bacterial flora and possible presence of Gram-negative intracellular diplococci. Bacterial vaginosis (BV) was diagnosed using Amsel's criteria (15) and after microscopic evaluation of the Gram-stained specimens.
CSF Gram stain results showed gram-positive diplococci resembling Streptococcus pneumoniae.
Investigations: A 2-day blood culture revealed a Gram-negative diplococci. Further tests identified the causative organism as N.
Within twelve hours, blood cultures returned positive for gram-negative diplococci, later identified as N.
These 2 cell projections facilitate the adhesion of diplococci to the endothelium and help meningococci to resist the shear stress and blood flow existing in capillaries and microvessels.
Gram-positive diplococci appearance in gram-stained smears were assessed as streptococci.
Blood cultures grew Gram-negative diplococci identified as Neisseria meningitidis.
