Is Branhamella and Moraxella the same?
Branhamella (Moraxella) catarrhalis is a gram-negative diplococcus that is morphologically indistinguishable from Neisseria. In 1970, M catarrhalis was transferred to a new genus, Branhamella, and separated from other species of Moraxella.
Is Moraxella a diplococci?
NATURE. Moraxella spp. are Gram-negative diplococci that morphologically and phenotypically resemble Neisseria spp. They are strictly aerobic, oxidase-positive, catalase-positive, DNAse-positive and asaccharolytic.
What disease does branhamella Catarrhalis cause?
Ear infections. catarrhalis is one of the most common causes of ear infections (otitis media) in children. About 15% to 20% of acute ear infections are caused by this bacterium.
What disease is caused by Moraxella?
A number of common childhood illnesses, including some middle ear (otitis media) and sinus infections (sinusitis), are caused by Moraxella catarrhalis bacteria. On rare occasions, this same organism may cause a blood infection (bacteremia), an eye infection (conjunctivitis), and meningitis in newborns.
What antibiotics treat Moraxella?
Amoxicillin-clavulanate, second- and third-generation oral cephalosporins, and trimethoprim-sulfamethoxazole (TMP-SMZ) are the most recommended agents. Alternatively, azithromycin or clarithromycin can be used.
What bacteria are diplococci?
A diplococcus (plural diplococci) is a round bacterium (a coccus) that typically occurs in the form of two joined cells.
Is branhamella Catarrhalis Gram positive or negative?
gram-negative
Moraxella (Branhamella) catarrhalis, formerly called Neisseria catarrhalis or Micrococcus catarrhalis, is a gram-negative, aerobic diplococcus frequently found as a commensal of the upper respiratory tract (124, 126; G.
What bacteria are gram-positive diplococci?
Gram Positive Diplococci Bacteria Two of the most common Gram-positive diplococcus includes Streptococcus pneumoniae and Enterococcus species. Normally, Streptococcus pneumoniae lives as a commensal in the mucosal surfaces of the respiratory system in human beings.
What disease is caused by diplococci?
Bacteremia due to Diplococcus pneumoniae frequently occurs during the course of pneumococcal pneumonia, particularly when the infection is fulminating. Endocarditis, most commonly involving the aortic valve, may complicate pneumococcal pneumonia and is characterized by persistent pneumococcal bacteremia.
What infection does Moraxella catarrhalis cause?
M. catarrhalis is a common cause of otitis media (middle ear infections) in infants and children in whom the bacteria are naturally present in the nasopharynx.
What is Moraxella catarrhalis infection?
Moraxella catarrhalis is a gram-negative diplococcus that commonly colonizes the upper respiratory tract. It is a leading cause of otitis media in children, acute exacerbations of chronic obstructive pulmonary disease (COPD), and acute bacterial rhinosinusitis.
Where is Moraxella found?
Moraxella organisms are Gram-negative cocci in the family Neisseriaceae. They were previously known as diplococcus of Morax-Axenfeld. Moraxellae are normal inhabitants of the upper respiratory tract and are also found on the skin and in the urogenital tract.
