Gram stain of the cerebral spinal fluid demonstrates lancet-shaped, gram-positive cocci. A lumbar puncture is performed and cerebral spinal fluid studies demonstrate an elevated opening pressure, elevated protein, decreased glucose, and a leukocytosis. Physical examination is significant for nuchal rigidity and an inability to extend at the knee while the hips are flexed at 90 °. Her symptoms are associated with neck stiffness and nausea.

A 56-year-old man presents to the emergency department for a severe headache, generalized malaise, and fatigue.

Predominant or pure growth of M.catarrhalis in throat swabs from cases of L.R.T.I. Healthy adults are rarely colonised with this organism, whereas most infants have upper respiratory tract colonisation at some time in the first several years of life. Multidrug resistance to >3 antimicrobials was seen in 22 (34.9%) of cases. catarrhalis colonisation is highly dependent on age. catarrhalis causes an estimated 2-4 million exacerbations of chronic obstructive pulmonary disease in adults annually in the United States. The isolates showed maximum resistance to cotrimoxazole (82.5%), penicillin (77.7%), and ampicillin (71.4%) while susceptibility was maximum to cefotaxime (87.3%) followed by tetracycline (85.7%) ciprofloxacin (84.1%), erythromycin (80.9%) amikacin (79.3%), gentamycin (77.7%), and cefazolin (76.2%). DOI: 10.1086/599375 Abstract Moraxella catarrhalis is an exclusively human pathogen and is a common cause of otitis media in infants and children, causing 15-20 of acute otitis media episodes. catarrhalis were isolated from a tertiary care hospital. Assessment of clinical significance of M.catarrhalis was ascertained on the basis of preformed criteria.Ī total of 63 clinically significant M. The study was conducted over 1-year period inpatients of lower respiratory tract infections (L.R.T.I.) in P.G.I.M.S. Therefore, appropriate antimicrobial agents are required for eradication and prevention of spread of the organism. Moraxella catarrhalis is gaining significance as a pathogen over few decades because of increased rate of isolation in respiratory specimens and due to emergence of multidrug resistant strains.
