Nuevo agente descrito productor de neumonia

: "Didier Raoult, MD, from Marseille, France,[1] reviewed Mimi virus -- a newly described, giant (400 nm in diameter) DNA virus that appears as a gram-positive coccus, multiplies in human macrophages, and is found in water and intra-amoebae (eg, Legionella).[2] Evidence that this organism causes pneumonia was supported by its detection by polymerase chain reaction (PCR) in bronchoalveolar lavage (BAL) specimens. Serologic studies showed elevated titers (> 1:100) by microimmunofluorescence in 146/497 (29%) patients with community-acquired pneumonia (CAP), compared with 95/511 (19%) controls (P = .001), and seroconversion in 5/26 (19%) CAP patients vs 0/50 controls. The author concluded that this is a new family of giant viruses that are as large as Mycoplasma, appear as a gram-positive coccus, are found in water, and may cause community-acquired or nosocomial pneumonia"

aunque me llama la atención que diga que son virus tan grande que se ven como gram positivo, no sabia yo de eso. Ya vere que hay de esto
