We present a case of acute endophthalmitis caused by Leuconostoc spp. following intravitreal bevacizumab injection. An 86-year-old immunocompetent female developed acute endophthalmitis after intravitreal injection of bevacizumab for neovascular age-related macular degeneration. The patient presented with pain, visual acuity of hand motions, hypopyon, and dense vitritis 96 h after treatment. Sh...

Brucellosis is one of the most important reemerging zoonoses in many countries. Brucellosis is caused by Gram-negative coccobacillus belonging to genus Brucella. Human brucellosis often makes the diagnosis difficult. The symptoms and clinical signs most commonly reported are fever, fatigue, malaise, chills, sweats headaches, myalgia, arthralgia, and weight loss. Some cases have been presented w...

In September 2012, five Bolivian squirrel monkeys housed in a zoological park died within sequential several days without obvious clinical signs. In a necrospy, one monkey presented swelling of the kidney with multifocal white nodules in the parenchyma, and other two had pulmonary congestion. Histopathologically, multifocal bacterial colonies of gram-negative coccobacillus were found in the sin...

genetically related to members of the genus Actinobacillus within the family Pasteurellaceae [9] which also comprises the genera Pasteurella and Haemophilus, is a nonmotile, nonhemolytic, facultatively anaerobic, gram-negative coccobacillus. Conventional methods for it’s detection are usually based upon bacteriological examinations that also help in distinguishing the two described biotypes of ...

Moraxella nonliquefaciens is a Gram-negative coccobacillus considered as a commensal organism from the upper respiratory tract, with low pathogenic potential. The phenotypical conventional identification is difficult and the matrix-assisted laser desorption/ionization time-of-flight technology has increased the resolution of identification of this bacterium. We report a fatal case of endocardit...

Acinetobacter baumannii is a gram-negative, nonfermentative coccobacillus that causes infections in immunocompromised and chronically ill patients and is associated with multidrug resistance. Two days before receiving her nonmyeloablative stem cell allograft, a patient with acute myeloid leukemia developed Acinetobacter baumannii bacteremia that caused septic shock which was successfully treate...

Strain CPCC 100056(T), which was isolated from a soil sample collected from the Qinghai-Tibet plateau, China, was subjected to a polyphasic taxonomic study. The organism was coccobacillus-shaped, non-motile and formed vinaceous colonies on ISP2 agar medium. The respiratory quinone was ubiquinone-10. The major fatty acids were C(18:1)omega7c and C(16:1)omega7c and/or C(16:1)omega6c. The G+C cont...

Rhodococcus equi is a Gram-positive coccobacillus that can cause a variety of infections in humans, most commonly severe pneumonia.1-4 These infections typically occur in immunocompromised hosts, although, rarely, immunocompetent hosts may be affected as well.1-4 Nonequi Rhodococcus species have been implicated in human disease, albeit less commonly than R equi. We report a case of severe cavit...

The bacterium Kingella kingae is a species of Gram-negative coccobacillus usually found in the oropharynx. This is an emerging pathogen reported to cause bacteraemia, endocarditis, and osteoarticular infections in children and endocarditis in the immunocompromised adult. However, there are few cases of isolated joint infections reported in the immunocompetent adult. Due to specific isolation te...

Acinetobacter baumannii is an aerobic Gram-negative coccobacillus that causes nosocomial pneumonia in patients on mechanical ventilation or previously treated with broad-spectrum antibiotics. Nevertheless, community-acquired pneumonia (CAP) caused by A. baumannii, especially multi-drug resistant (MDR) strains, is rare. We experienced the first case of CAP caused by MDR A. baumannii in Korea in ...
