The urethral culture shows a gram-negative oxidase-positive diplococcus
and testing confirms N gonorrhoeae.
Vaginal medium of mares had the following nonpathogenic microorganisms: Lactobacterium, Bifidobacterium, Sarcina, Corynebacterium, partly representatives of the genus Diplococcus
, Streptococcus, and Staphylococcus.
In Carol A Kauffmann M D et al (19) study of 5 patients, Diplococcus
pneumonia was isolated from 4 patients and 1 patient didn't show any organisms and he had previously received penicillin.
The gram-negative diplococcus
Neisseria gonorrhoeae is the causal agent of gonorrhoea, one of the two most common sexually transmitted diseases .
In patients aged <12 months, a suspected case of meningitis occurs when fever is accompanied by a bulging fontanelle Probable case of bacterial meningitis: Suspected case of acute meningitis, as defined above, with turbid cerebrospinal fluid (CSF) Probable case of meningococcal meningitis: Suspected case of acute meningitis, as defined above, and Gram stain showing gram-negative diplococcus
or ongoing epidemic or petechial or purpural rash To confirm a case of meningococcal meningitis: Suspected case, as defined above, with either positive-CSF antigen detection for Neisseria meningitidis or positive CSF or blood culture with identification of N.

Culture of Neisseria gonorrhoeae, a Gram-negative diplococcus
, requires plating on selective media and incubation at 36 [degrees]C in a C[O.sub.2]-enriched atmosphere.

Fastidious, encapsulated, aerobic, gram-negative diplococcus
, grows best in a capnophilic environment, non-hemolytic and tests positive both for catalase and Kovac's oxidase reactions.
In 1884, Italian pathologists Ettore Marchiafava and Angelo Celli described intracellular micrococci in cerebrospinal fluid, and in 1887, Anton Wiechselbaum identified the meningococcus (designated as Diplococcus
intracellularis meningitidis) in cerebrospinal fluid and established the connection between the organism and epidemic meningitis.
A Gram-negative diplococcus
was seen on microscopy.
