could bacteria that do not contain cell walls be stained using gram stain
Gram stain Historically, the gram-positive forms made up the phylum Firmicutes, a name now used for the largest group. It includes many well-known genera such as Bacillus, Listeria, Staphylococcus, Streptococcus, Enterococcus, and Clostridium.[19][citation needed] It has also been expanded to include the Mollicutes, bacteria like Mycoplasma that lack cell walls and so cannot be stained by Gram, but are derived from such forms.[20][citation needed]
Abdominal examination On light palpation, the examiner tests for any palpable mass, rigidity, or pain.
Swallowing 5) Closure of the nasopharynx
Gram-positive bacteria Although bacteria are traditionally divided into two main groups, Gram-positive and Gram-negative, based on their Gram stain retention property, this classification system is ambiguous as it refers to three distinct aspects (staining result, envelope organization, taxonomic group), which do not necessarily coalesce for some bacterial species.[4][5][6][7] The Gram-positive and Gram-negative staining response is also not a reliable characteristic as these two kinds of bacteria do not form phylogenetic coherent groups.[4] However, although Gram staining response is an empirical criterion, its basis lies in the marked differences in the ultrastructure and chemical composition of the bacterial cell wall, marked by the absence or presence of an outer lipid membrane.[4][8]
Limit of a function (the Dirichlet function) has no limit at any x-coordinate.
