The finding of coccoid bacteria on a Pap test is of no consequence with otherwise normal test findings and no infectious symptoms. However, if there is enough inflammation to obscure the detection of precancerous and cancerous processes, it may indicate treatment with a broad-spectrum antibiotic for streptococci and anaerobic bacteria (such as ...
Cocci can grow in pairs, chains, or clusters, depending on their orientation and attachment during cell division. In contrast to many bacilli-shaped bacteria, most cocci bacteria do not have flagella and are non-motile. [5] Cocci is an English loanword of a modern or Neo-Latin noun, which in turn stems from the Greek masculine noun κόκκος ...
Colonies become visible in 24–48 hours. Initially, they are small, with about a 1.0-mm diameter and with a grey-yellow colour. After 3–4 days, the isolated bacterial colonies can reach a 3-mm diameter, and they have a rough surface and yellow-golden pigmentation. Beta hemolysis can be seen around the colonies.

Gram-positive bacteria have a thick mesh-like cell wall made of peptidoglycan (50–90% of cell envelope), and as a result are stained purple by crystal violet, whereas gram-negative bacteria have a thinner layer (10% of cell envelope), so do not retain the purple stain and are counter-stained pink by safranin. There are four basic steps of the ...
However, it has retained some clinical usefulness even after the taxonomic changes, [1] and as of 2018, Lancefield designations are still often used to communicate medical microbiological test results. The classification assigns a letter code to each serotype. There are 20 described serotypes assigned the letters A to V (excluding E, I and J). [3]
Kocuria is a genus of gram-positive bacteria. Kocuria is named after Miloslav Kocur, a Czech microbiologist. It has been found in the milk of water deer and reindeer. [3] Cells are coccoid, resembling Staphylococcus and Micrococcus, and can group in pairs, chains, tetrads, cubical arrangements of eight, or irregular clusters.
Pap stain Phase contrast microscopy of clue cells in a vaginal swab Clue cells are epithelial cells of the vagina that get their distinctive stippled appearance by being covered with bacteria . The etymology behind the term "clue" cell derives from the original research article from Gardner and Dukes describing the characteristic cells.
Brachybacterium is a genus of Gram positive, nonmotile bacteria.The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. The genus name comes from Greek word brachy, meaning short, and Latin bacterium, meaning rods, referencing the short rods noted during the exponential phase.
