Both are nonlactose fermenting, facultatively anaerobic, gram-negative bacilli
Pharyngeal flora in ambulatory alcoholic patients: prevalence of gram-negative bacilli
Aeromonas hydrophila is a motile gram-negative bacilli
typically causing infection after exposure of wounds to fresh water, soil, or marine creatures, and oral consumption of contaminated food (1,2).
standardized system identification enteric gram-negative bacilli
and no troublesome 8 trials combining conventional 12 trials of assimilation and a database.
The situation is particularly dramatic for certain species of bacteria, Gram-negative bacilli
For gram-negative bacilli
, including extended-spectrum [beta]-lactamases (ESBL), identification and susceptibility testing were performed by conventional techniques and by MicroScan NC50 panels (Dade-Behring, West Sacramento, CA, USA) (5).
In general, the databases available in the commercial systems are best for common aerobic gram-negative bacilli
and gram-positive cocci, but may be less comprehensive for esoteric organisms (e.

Our study revealed that chronic periodontitis flora is diverse and composed of both motile and non motile types and gram positive and negative (cocci, rod-rights) as well as its rarity in gram-negative bacilli
and gram-positive filaments.
Other organisms involved include streptococci, gram-negative bacilli
, and Neisseria gonorrhoeae (in sexually active young adults).
agar, there were found gram-negative bacilli
that were lactose fermenters.
aureus, 17% with vancomycin-resistant enterococci, and 12% with gram-negative bacilli
resistant to extended-spectrum [beta]-lactams.
It is most commonly associated with a group of gram-negative bacilli
collectively known as HACEK (for Hemophilus parainfluenzae, H aphrophilus, Hemophilus paraphrophilus, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae).
As a class of microbes, gram-negative bacilli
cause 3% to 10% of community-acquired pneumonias.
Numerous studies have shown that Gram-negative bacilli
ID scores are superior to Gram-positive cocci ID scores, particularly problematic streptococci (3).
