Diplococcus A diplococcus (plural diplococci) is a round bacterium (a coccus) that typically occurs in the form of two joined cells. Examples of gram-negative diplococci are Neisseria sp., Moraxella catarrhalis, Acinetobacter, and Brucella. Examples of gram-positive diplococci would be Streptococcus pneumoniae and enterococcus.

Lupus: Systemic Lupus Erythematosus (SLE) People with lupus have periods in which they are feeling well, called remission, and periods of worsening symptoms, called flares. Lupus patients can often predict the onset of flares due to specific warning signs, such as worsening fatigue and/or onset of headache, fever, dizziness, rash, and/or pain (Phillips 1991).YPES OF LUPUS. The term lupus commonly refers to systemic lupus erythematosus, or SLE, but there are other types of lupus as well, each with distinct signs and symptoms (Firestein 2009). Systemic lupus erythematosus (SLE). This is the disease often simply referred to as lupus.

Coccus Streptococcus (genus Streptococcus), group of spheroidal bacteria belonging to the family Streptococcaceae. The term streptococcus (“twisted berry”) refers to the bacteria’s characteristic grouping in chains that resemble a string of beads. Streptococci are microbiologically characterized as gram-positive and nonmotile.

Lactococcus Lactococcus is a genus of lactic acid bacteria that were formerly included in the genus Streptococcus Group N1. They are known as homofermentors meaning that they produce a single product, lactic acid in this case, as the major or only product of glucose fermentation.Their homofermentative character can be altered by adjusting cultural conditions such as pH, glucose concentration, and nutrient limitation.They are gram-positive, catalase-negative, non-motile cocci that are found singly, in pairs, or in chains. The genus contains strains known to grow at or below 7˚C.Nine species of Lactococcus are currently recognized along with four subspecies.hey are gram-positive, catalase-negative, non-motile cocci that are found singly, in pairs, or in chains.

Enterococcus Enterococcus is a large genus of lactic acid bacteria of the phylum Firmicutes. Enterococci are Gram-positive cocci that often occur in pairs (diplococci) or short chains, and are difficult to distinguish from streptococci on physical characteristics alone.Two species are common commensal organisms in the intestines of humans: E. faecalis (90-95%) and E. faecium (5-10%).Rare clusters of infections occur with other species, including E. casseliflavus, E. gallinarum, and E. raffinosus.mportant clinical infections caused by Enterococcus include urinary tract infections, bacteremia, bacterial endocarditis, diverticulitis, and meningitis. Sensitive strains of these bacteria can be treated with ampicillin, penicillin and vancomycin.
