Bergey's Manual Trust was established in 1936 to sustain the publication of Bergey's Manual of Determinative Bacteriology and supplementary reference works. The Trust also recognizes individuals who have made outstanding contributions to bacterial taxonomy by presentation of the Bergey Award and Bergey Medal, jointly supported by funds from the Trust and from Springer, the publishers of the ...
Members of the genus Macrococcus are Gram-positive, nonmotile, non-spore-forming cocci that are coagulase negative and catalase positive. They can be distinguished phenotypically from most staphylococci on the basis of their cellular morphology (they are 2.5 – 4.0 times larger in diameter compared to Staphylococcus aureus) and their positive cytochrome c oxidase reaction.
Chains of S. pyogenes bacteria (orange) at 900× magnification Gram stain of Streptococcus pyogenes. Unlike most bacterial pathogens, S. pyogenes only infects humans. Thus, zoonotic transmission from an animal (or animal products) to a human is rare. [8] S. pyogenes typically colonizes the throat, genital mucosa, rectum, and skin. Of healthy ...
Gram-positive bacteria are capable of causing serious and sometimes fatal infections in newborn infants. [19] Novel species of clinically relevant gram-positive bacteria also include Catabacter hongkongensis, which is an emerging pathogen belonging to Bacillota. [20]
Streptococcus is a genus of gram-positive or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota. [2] Cell division in streptococci occurs along a single axis , thus when growing they tend to form pairs or chains, which may appear bent or twisted.
IAP has been considered to be associated with the emergence of resistant bacterial strains and with an increase in the incidence of early-onset infections caused by other pathogens, mainly Gram-negative bacteria such as Escherichia coli. Nevertheless, most studies have not found an increased rate of non-GBS early-onset sepsis related to the ...
Anaerococcus is a genus of bacteria. Its type species is Anaerococcus prevotii. [1] These bacteria are Gram-positive and strictly anaerobic. [2] [3] [4] The genus Anaerococcus was proposed in 2001. [2] [4] Its genome was sequenced in August 2009. The genus Anaerococcus is one of six genera classified within the group GPAC (Gram-Positive ...
Kocuria rosea is a gram-positive bacteria that is catalase-positive and oxidase-positive. It has a coccus shape that occurs in the tetrad arrangement and is a strict aerobe that grows best from 25 to 37 °C. [2] K. rosea has also been found to cause urinary tract infections in people with weakened immune systems. [3]
