Sepsis caused by Capnocytophaga canimorsus in an immunocompetent patient

Fatal septic shock and Waterhouse-Friderichsen syndrome caused by serovar B Capnocytophaga canimorsus in an immunocompetent patient. Case report and review

“…All three cases occurred in 2021 in a period of 3 months, but no relationship was found between patients and pets. One of the cases was also a sepsis by C. canimorsus serovar B ( Table 1 ), as in the case we describe here [ 17 ]. The third patient was an HIV patient with no history of bites who developed a septic arthritis by C. canimorsus serovar A [ 20 ].…”

Identification of Anaerobiospirillum succiniciproducens by MALDI-TOF mass spectrometer. A bacteremia in an immunocompetent patient

“…For all these reasons, identification by MALDI-TOF mass spectrometry is a very important diagnostic tool, since it is a fast and accurate method that has been previously tested for the identification of A. succiniciproducens [6,7]. In addition, direct identification of the blood culture by MALDI-TOF makes the process even faster, being useful in the identification of potentially fatal and growth-demanding organisms such as Capnocytophaga canimorsus [11] While 16S ribosomal RNA gene sequencing is a more accurate method of identification, it is also more complicated, laborious and takes longer to arrive at identification. In fact, since Fox B et al conducted their study in 2018 the Bruker MALDI-TOF database has been updated and includes now the main spectra of A. succiniciproducens [7].…”
