2016年9月28日 · The cerebrospinal fluid (CSF) Gram stain suggested Streptococcus pneumoniae: Gram-positive diplococci with a surrounding clear area indicative of a bacterial capsule. Her CSF and blood cultures grew penicillin-resistant S pneumoniae serotype 35B.

Here we review the epidemiology, virulence mechanisms, and host response to the most frequently isolated Gram-positive uropathogens: Staphylococcus saprophyticus, Enterococcus faecalis, and Streptococcus agalactiae.

Interpretation of Key Phrases “Gram positive cocci in clusters” may suggest Staphylococcus species. "Gram positive cocci in pairs and chains" may suggest Streptococcus species or Enterococcus species “Branching Gram positive rods, modified acid fast stain positive” may suggest Nocardia or Streptomyces species

2023年5月30日 · Gram-positive bacteria comprise cocci, bacilli, or branching filaments. Gram-positive cocci include Staphylococcus (catalase-positive), which grows clusters, and Streptococcus (catalase-negative), which grows in chains.

Kocuria kristinae (formerly known as Micrococcus kristinae) is a type of Micrococcus (GPC) in clusters, aerobic, that normally colonizes the skin. It has been implicated in IV catheter infections, in the formation of gallstones (acute cholecystitis), and urinary tract infections. It often produces an orange or yellow pigment on blood agar.

Comprehensive information on infectious diseases caused by gram-positive cocci, including diagnosis, treatment, and management.

Gram-positive cocci, either in chains as with β-haemolytic streptococci or viridans streptococci, or as diplococci, as with pneumococci. Capsules of Strep. pneumoniae may occasionally be seen in Gram films and in special stained smears for capsules.

gram-negative diplococci are expected in a patient’s CSF, not gram-negative diplococci as well as gram-positive cocci. If both of these morphotypes are seen, most likely the problem is over-or underdecolorization. The problem with decolorization must also be considered when the shape of the organism does not “fit” the Gram stain.
