Cultures of these specimens yielded Neisseria catarrhalis. Accurately and clearly draw the size, shape, arrangement, and Gram stain reaction of the cells in each of the eight different samples your section has stained. Staphylococcus aureus and Klebsiella pneumoniae Staphylococcus aureus and Candida albicans Enterococcus faecalis and Branhamella catarrhalis Enterococcus faecalis and Klebsiella pneumoniae Branhamella catarrhalis Abundant Gram-negative cocci in sputum. Many of them are intracellular, lying mostly in pairs and look like coffee beans (Gram stain). Discovered at the end of the 19th century, Moraxella catarrhalis (formerly Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis) aerobic, asaccharolytic, gram-negative coccobacilli or diplococci that tend to resist decolorization on Gram stain. 1 M. catarrhalis, M. osloensis, M.

M. catarrhalis is a large, kidney-shaped, Gram-negative diplococcus. It can be cultured on blood and chocolate agar plates after an aerobic incubation at 37 °C for 24 hours. Cultures revealed gray-white hemispheric colonies about 1 mm in diameter. These colonies were fragile and easy to crumble, and appeared to have a waxy surface. The colonies were confirmed using Gram staining and biochemical tests for catalase, oxidase, DNAse, and butyrate esterase production (Remel™ catarrhalis test disc). This tributyrin spot test helped in differentiating M. catarrhalis from other nonpathogenic Neisseria species that are generally found in the respiratory tract. To determine the possible role of Branhamella (formerly Neisseria) catarrhalis as a respiratory pathogen, we screened quality sputa (defined by cellular criteria) that showed numerous gram-negative cocci on Gram's stain for the presence of B catarrhalis.

Gram stain of transtracheal aspirate revealed intraleukocytic and extraleukocytic gram-negative diplococci, and a beta-lactamase producing strain of Branhamella catarrhalis was cultured.

2021-03-22 2020-06-06 Branhamella catarrhalis has been implicated previously as a cause of bronchopulmonary infections. Sputum Gram's stain and culture results suggesting significant infection with beta-lactamase-producing strains of B. catarrhalis were correlated with a retrospective chart review of eight pediatric and ten adult patients. Branhamella catarrhalis as a lower respiratory tract pathogen in patients with chronic lung disease. Nicotra B, Rivera M, Luman JI, Wallace RJ Jr. To determine the possible role of Branhamella (formerly Neisseria) catarrhalis as a respiratory pathogen, we screened quality sputa (defined by cellular criteria) that showed numerous gram-negative cocci on Gram's stain for the presence of B catarrhalis. Gram stain of transtracheal aspirate revealed intraleukocytic and extraleukocytic gram-negative diplococci, and a beta-lactamase producing strain of Branhamella catarrhalis was cultured. Therapy with erythromycin resulted in resolution of symptoms and eradication of the organism.

The whole genomic sequence of Moraxella catarrhalis strain RH4 (16S rRNA subtype 1strain) has been reported. 18 The Moraxella immunoglobulin D (IgD)–binding protein (MID, also named hemagglutinin) is another extensively studied and highly conserved OMP that has a unique ability to bind IgD and also type II alveolar epithelial cells.

In all cases gram stain of the urethral exudates revealed intracellular gram-negative diplococci morphologically compatible with Neisseria gonorrhoeae. Branhamella (Neisseria) catarrhalis should be considered as a potential cause of acute urethritis in men with urethral discharge Gram-positive diplococci with capsule (haloe) formation, located outside neutrophils. Panel 2: Bacteria seen in sputum preparations Methicillin-resistant Staphylococcus aureus (MRSA) (Gram). Irregularly clustered Gram-positive cocci in and outside neutrophils.
