Within 48 hours, a pure culture of pink, mucoid, light, large colonies characterized of gram-postive, urease and catalase positive coccobacillus
consistent with R.
Here we describe a case of a patient with a brain abscess culture of the abscess drainage material yielded a gram negative coccobacillus
that was initially identified as Brucella spp.
First isolated in the USA in 1934 by Mclver and described further by Schleifstein in 1939, Yersinia enterocolitica is a gramnegative coccobacillus
that was not recognized as a human pathogen until the late 1960s, when it was identified in foodborne gastroenteritis (4).
Brucellosis is a highly contagious, acute, subacute or chronic course zoonosis infection caused by coccobacillus
, non-motile, non-spore-forming, gram negative Brucella group bacteria.1-3 The disease is transmitted to humans via infected cattle, sheep, goats, consumption of meat and dairies, and direct contact or inhalation.4
Suttonella indologenes, a gramnegative coccobacillus
that was sensitive to ampicillin, cephalosporines, ciprofloxacin and resistant to imipenem and meropenem was isolated from all of the blood culture specimens.
Less specific answers such as gram-negative bacillus, aerobic, not otherwise specified; gram-negative coccobacillus
, aerobic, not otherwise specified; gram-negative bacillus, not otherwise specified; and gram-negative coccobacillus
, not otherwise specified were considered "satisfactory," although less complete.
Whooping cough is caused by the bacterium Bordetella Pertussis is very small Gram_negative aerobic coccobacillus
that appear singly or in pairs Bordetella is placed among the Gram-Negative aerobic rods and cocci called coccobacillus
(Bloom et al., 2003).
Brucellosis results from a gram-negative coccobacillus
of which there are many varieties.
kingae is difficult because the gram-negative coccobacillus
is hard to grow on culture, requires an enhanced isolation methodology, and takes a little longer than normal to grow, which may require laboratories to hold on to culture plates for up to 7 days.
Haemophilus parainfluenzae is a gram-negative coccobacillus
frequently found as normal flora in the oropharaynx of human hosts.
Tularemia, Francisella tularensis is a small non-motile gram negative coccobacillus
that can survive for weeks at low temperatures in water, soil, vegetation, and decaying animal carcasses.
F tularensis is a small (0.2 to 0.7 mm), aerobic, gram-negative coccobacillus
that exists in vivo as a facultative intracellular pathogen.
