Moraxella

 [mo″-rak-sel´ah]
a genus of gram-negative, aerobic bacteria found as parasites on the mucous membranes of mammals. There are two subgenera: M. (Moraxella), occurring as rods, and M. (Branhamella), occurring as cocci. M. (Branhamella) catarrha´lis occasionally causes respiratory disease; M. (Moraxella) lacuna´ta causes conjunctivitis and corneal infections.

Moraxella

(mōr'ak-sel'ă),
A genus of obligately aerobic nonmotile bacteria (family Neisseriaceae) containing gram-negative coccoids or short rods that usually occur in pairs. They do not produce acid from carbohydrates, are oxidase positive, penicillin susceptible, and infect the mucous membranes of humans and other mammals. The type species is Moraxella lacunata.

Moraxella

/Mo·rax·el·la/ (mo-rak-sel´ah) a genus of bacteria (family Neisseriaceae), made up of gram-negative, short, aerobic, nonpigmented organisms found as parasites and pathogens on the mucous membranes of mammals; it includes two subgenera: M. (Moraxella) and M. (Branhamella). M. (Branhamel´la) catarrha´lis is a normal inhabitant of the human nasal cavity and nasopharynx, occasionally causing otitis media or respiratory disease. M. (Moraxel´la) lacuna´ta causes conjunctivitis and corneal infections.

Moraxella

a genus of the Neisseriaceae family of gram-negative nonmotile cocci. They are found as pathogens and parasites on the mucous membranes of warm-blooded animals.

The main cause of this distressing and economically important disease is the bacteria Moraxella bovis, although other infectious and physical factors may increase severity and susceptibility to the disease.
The clinical significance of relatively low-virulence isolates, such as coagulase-negative staphylococci, Enterococcus faecalis, non-fermentative Gram-negative bacilli other than Pseudomonas, Cornyebacteria aquaticuam, Moraxella catarrhalis, Streptococcus viridans, and Candida species, is difficult to ascertain.
Los estudios bacteriologicos en larvas de los estadios II y III, asi como del agua utilizada para su levantamiento, revelaron la presencia de abundante flora bacteriana, con predominancia de representantes de los generos Aeromonas, Arthrobacter, Flavobacterium, Moraxella, Pseudomonas y Vibrio.
Resistant strains of Moraxella catarrhalis are found over 80% of the time in North America and 50-80% of the time in Latin America.
The organisms most commonly identified in patients with AOM are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis (Shapiro & Bluestone, 1995; Eden et al.
FACTIVE remains approved for the treatment of CAP caused by multi-drug resistant Streptococcus pneumoniae, Klebsiella pneumoniae or Moraxella catarrhalis with a duration of therapy of seven days.
12-13) However, if the failure rate was 16% with amoxicillin/clavulanate (which is effective against beta-lactamase-producing Haemophilus influenzae and Moraxella catarrhalis, whereas amoxicillin is not), then the predicted failure rate with amoxicillin for 10 days should be double (34%) or triple (51%) had amoxicillin been used as recommended by the AAP in light of the bacterial resistance of otopathogens.
The most common causative agent of infectious bovine keratoconjunctivitis is Moraxella bovis.
Gram negative bacteria include Moraxella catarrhalis (13%), Klebsiella pneumoniae (5%), Hemophilus influenzae (2%), E.
