They are often referred to as “kidney bean”–shaped diplococci. Direct Gram staining of urethral discharge from symptomatic males with urethritis is an important test Neisseria meningitidis often causes meningitis and meningococcemia; however, meningococcal pneumonia is quite rare. Herein, we report a case of non-invasive meningococcal pneumonia initially misdiagnosed as pneumonia due to Moraxella catarrhalis on the basis of a Gram stain in a 43-year-old woman with asthma, type 2 diabetes mellitus, and schizophrenia. When gram staining M. catarrhalis, the gram stain color would be pink, and the test would be considered gram-negative. Gram negative organisms will stain pink because they have both a cytoplasmic membrane and an outer membrane as well as a thin cell wall (Cowan 2020). Bacterial cell walls are made of a macromolecule called peptidoglycan.

Instead, like any other Gram-negative bacteria, it stains pink with safranin dye. M. catarrhalis is an exclusively human pathogen and is common cause of otitis media in infants and children and they are an important cause of lower respiratory tract infections, particularly in adults with chronic obstructive pulmonary disease (COPD). Gram Stain. The members of the genus Neisseria discussed in this chapter and M. catarrhalis appear as gram-negative diplococci (Figure 40-2) with adjacent sides flattened. They are often referred to as “kidney bean”–shaped diplococci. Direct Gram staining of urethral discharge from symptomatic males with urethritis is an important test Neisseria meningitidis often causes meningitis and meningococcemia; however, meningococcal pneumonia is quite rare.
