| gram-negative bacteria | <microbiology> Bacteria which lose crystal violet stain but are stained pink when treated by gram's method. (12 Dec 1998) |
|---|---|
| gram-negative bacterial infections | <microbiology> Infections caused by bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative chemolithotrophic bacteria | <microbiology> A large group of bacteria including those which oxidise ammonia or nitrite, metabolise sulfur and sulfur compounds, or deposit iron and/or manganese oxides. (12 Dec 1998) |
| gram-negative facultatively anaerobic rods | <microbiology> A large group of facultatively anaerobic, rod-shaped bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative oxygenic photosynthetic bacteria | <microbiology> Widely distributed unicellular or multicellular bacteria. The cyanobacteria use chlorophyll a and phycobilins for oxygenic photosynthesis while genera in the prochlorales use both chlorophyll a and b but not phycobilins. (12 Dec 1998) |
| gram-positive | <microbiology> Bacteria that retain the stain or that are resistant to decolourisation by alcohol during Gram's method of staining. This is a primary characteristic of bacteria whose cell wall is composed of a thick layer of peptidologlycan containing teichoic and lipoteichoic acid complexed to the peptidoglycan.

| gram-positive asporogenous rods | <microbiology> A gram-positive, non-spore-forming group of bacteria comprising organisms that have morphological and physiological characteristics in common. (12 Dec 1998) |
| gram-positive asporogenous rods, irregular | <microbiology> A group of irregular rod-shaped bacteria that stain gram-positive and do not produce endospores. (12 Dec 1998) |
| gram-positive asporogenous rods, regular | <microbiology> A group of regular rod-shaped bacteria that stain gram-positive and do not produce endospores. (12 Dec 1998) |
| gram-positive bacteria | <microbiology> Bacteria which retain the crystal violet stain when treated by gram's method. (12 Dec 1998) |
| gram-positive bacterial infections | <microbiology> Infections caused by bacteria that retain the crystal violet stain (positive) when treated by the gram-staining method. (12 Dec 1998) |
| gram-positive cocci | <microbiology> Coccus-shaped bacteria that retain the crystal violet stain when treated by gram's method. (12 Dec 1998) |
| gram-positive endospore-forming bacteria | <microbiology> Bacteria that form endospores and are gram-positive. Representative genera include bacillus, clostridium, micromonospora, saccharopolyspora, and streptomyces. (12 Dec 1998) |
| gram-positive endospore-forming rods | <microbiology> Rod-shaped bacteria that form endospores and are gram-positive. Representative genera include bacillus and clostridium. (12 Dec 1998) |
| gram-positive rods | <microbiology> A large group of rod-shaped bacteria that retains the crystal violet stain when treated by gram's method. (12 Dec 1998) |
