Abstract:Cellulomonas is a rare but emerging human pathogen, causing infection in only 4 reported cases in the literature. We present the first case of ascending cholangitis with Cellulomonas bacteremia and sepsis, as well as a brief review of the literature. We summarize every case of Cellulomonas reported in the medical literature, including treatments and outcomes.
“…Mycobacterium related CIED infection was rarely found. There were case reports both from Asian and western countries . The most common isolated Mycobacterial organisms were in the M. fortuitum group, which account for approximately 50% of mycobacterial infections .…”
BackgroundDespite the long experience of cardiac implantable electronic device (CIED) implantation in Thailand, epidemiology of CIED infection in Thailand has never been studied.MethodsA retrospective cohort study was conducted at the cardiac referral center in Thailand to investigate incidence of CIED infection and causative organisms between October 2002 and December 2017. A matched case‐control study was performed to determine the factors associated with CIED infection.ResultsIncidence of CIED infection was 0.9% with a stable trend during the studied period. There were 54 episodes of CIED infection. The median (interquartile range) age of the patients was 67.5 (53.0‐75.0) years. A total of 29 (53.7%), 18 (33.3%), and 7 (13.0%) were permanent pacemaker, automatic implantable cardioverter‐defibrillator, and cardio‐resynchronization therapy‐related infection, respectively. Gram‐positive cocci were the most common organism (24 episodes, 44.4%). Gram‐negative bacilli were isolated in six episodes (11.1%). About 9.3% were polymicrobial and 35.2% were culture negative. Multivariate analysis showed that previous CIED infection and generator revision procedure were associated with CIED infection (odds ratio [OR] 48.56, 95% confidence interval [CI] 3.72‐633.62; P = 0.003 and OR 19.99, 95% CI 1.28‐333.24; P = 0.033 respectively). Forty (74.1%) cases were cured. Leaving device in situ was the only factor significantly associated with poor outcome (OR 11.40, 95% CI 1.52‐85.73; P = 0.018).ConclusionsIn Thailand, while CIED implantation is rising, incidence of CIED infection is stable. Microbiology of CIED infection in Thailand is similar to western countries, albeit a higher proportion of negative culture. Previous CIED infection and generator revision procedure are associated with CIED infection.

“…A published study of Lagier et al [27] noted that the Cellulomonas strain obtained spectrum did not match with any of the 11 spectra contained in the database. On the other hand, Marko et al [28] have successfully identified one Cellulomonas strain to the genus and species level by MALDI-TOF-MS. Cellulomonas genus was originally thought to be an opportunistic infection. However, 5 clinical cases were reported in immune-competent adults [29].…”

“…Mycobacteria and especially M. marinum are well‐known causes of disease in humans through contact with fish and the aquatic environment (Sunil et al, ; Thirunavukkarasu, Plain, de Silva, Marais, & Whittington, ; Verner‐Jeffreys et al, ). To the best of our knowledge, M. goodii has not been detected in fish to date; on the contrary, it is an emerging nosocomial human pathogen (Salas & Klein, ).…”
Doctor fish (Garra rufa, Heckel, 1843) are increasingly used for cosmetic treatment raising particular concerns regarding the potential transmission of infections to clients. Investigations of microbial causes undertaken in two outbreaks of mortality among G. rufa used for cosmetic treatment revealed the presence of multiple bacteria, including both fish and human pathogens such as Aeromonas veronii, A. hydrophila, Vibrio cholerae, Shewanella putrefaciens, Mycobacterium marinum and M. goodii. This range of bacteria indicates an intense microbial proliferation involving multiple pathogens, most likely induced by the poor health condition of the fish. Most of the detected pathogens are well‐known agents of zoonosis. Indeed, M. goodii is an emerging nosocomial human pathogen that has never been detected in fish to date, nor in other animals. This first detection of M. goodii associated with fish infection points out a new zoonotic potential for this pathogen. These findings point out that handling, poor environmental conditions and the presence of fish pathogens, that can compromise the immune system of fish, can result in a mixed microbial proliferation and increase the spread of waterborne bacteria, including zoonosis agents. Accordingly, the microbiological surveillance of fish used for cosmetic treatment is extremely important, particularly in association with mortality outbreaks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
