Supplementary Materials S1 Clinical details recorded, Sampling, DNA Extraction of Microbial DNA, 16S rRNA gene sequencing, Bioinformatic pipeline, Quantitative Polymerase Chain Reaction Clinical details recorded In addition to the microbial specimen, the following clinical features were also recorded for each patient: age, gender, infection type (primary or secondary, meaning initial or revision treatment), pain, tenderness to percussion, sinus tract and size of the periapical radiolucency, to determine the correlation between these features and microbial findings (Table 1). Prevalence of all clinical signs and symptoms (except periapical lesion size) were recorded on a binary scale [0 = absent, 1 = present], while the size of the radiolucency was measured in millimetres by two endodontic specialists on two- dimensional periapical radiographs (Planmeca Romexis, Coventry, UK). Sampling After anaesthesia, the tooth to be treated was isolated with a rubber dam (UnoDent, Essex, UK), and field decontamination was carried out before and after access opening, according to an established protocol, and shown to eliminate contaminating DNA (Data not shown). An access cavity was cut with a sterile bur under sterile saline irrigation (0.9% NaCl, Mölnlycke Health Care, Göteborg, Sweden), with contamination control samples taken. Root canal patency was assessed with a sterile K-file (Dentsply-Sirona, Ballaigues, Switzerland). For non-culture-based analysis, clinical samples were collected by inserting two paper points size 15 (Dentsply Sirona, USA) into the root canal. Each paper point was retained in the canal for 1 min with careful agitation, then was transferred to −80ºC storage immediately before further analysis. Cases of secondary endodontic treatment were sampled using the same protocol, with the exception that specimens were collected after removal of the coronal gutta-percha with Gates Glidden drills (Dentsply-Sirona, Switzerland). -
Aquatic Microbial Ecology 80:15
The following supplement accompanies the article Isolates as models to study bacterial ecophysiology and biogeochemistry Åke Hagström*, Farooq Azam, Carlo Berg, Ulla Li Zweifel *Corresponding author: [email protected] Aquatic Microbial Ecology 80: 15–27 (2017) Supplementary Materials & Methods The bacteria characterized in this study were collected from sites at three different sea areas; the Northern Baltic Sea (63°30’N, 19°48’E), Northwest Mediterranean Sea (43°41'N, 7°19'E) and Southern California Bight (32°53'N, 117°15'W). Seawater was spread onto Zobell agar plates or marine agar plates (DIFCO) and incubated at in situ temperature. Colonies were picked and plate- purified before being frozen in liquid medium with 20% glycerol. The collection represents aerobic heterotrophic bacteria from pelagic waters. Bacteria were grown in media according to their physiological needs of salinity. Isolates from the Baltic Sea were grown on Zobell media (ZoBELL, 1941) (800 ml filtered seawater from the Baltic, 200 ml Milli-Q water, 5g Bacto-peptone, 1g Bacto-yeast extract). Isolates from the Mediterranean Sea and the Southern California Bight were grown on marine agar or marine broth (DIFCO laboratories). The optimal temperature for growth was determined by growing each isolate in 4ml of appropriate media at 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50o C with gentle shaking. Growth was measured by an increase in absorbance at 550nm. Statistical analyses The influence of temperature, geographical origin and taxonomic affiliation on growth rates was assessed by a two-way analysis of variance (ANOVA) in R (http://www.r-project.org/) and the “car” package. -
Rapid Identification of Cardiobacterium Hominis by MALDI-TOF Mass Spectrometry During Infective Endocarditis
Jpn. J. Infect. Dis., 64, 327-329, 2011 Short Communication Rapid Identification of Cardiobacterium hominis by MALDI-TOF Mass Spectrometry during Infective Endocarditis Fráedáeric Wallet1,2*, Caroline Loäƒez1,2, Christophe Decoene1,2, and Renáe Courcol1,2 1University of Lille Nord de France, Lille; and 2CHU Lille, Lille, France (Received April 8, 2011. Accepted May 11, 2011) SUMMARY:WereportanewcaseofCardiobacterium hominis endocarditis identified during an acute coronary syndrome. The positivity of the blood cultures was confirmed rapidly (50 h) as a result of im- provements to the automated detection system, whereby it is no longer necessary to incubate the vials for long periods of time when Aggregatibacter-Cardiobacterium-Eikenella-Kingella infections is sus- pected. The phenotype-based VITEK 2 NH identification system is not able to distinguish between the two species of Cardiobacterium, as it does not contain C. valvarum in its library. The method for 16S rRNA gene sequence analysis is able to separate the two species but is not available in all laboratories. We used MALDI-TOF mass spectrometry, as an alternative, to rapidly distinguish between C. hominis and C. valvarum, because both species are contained in the system library. A 60-year-old man, without coronary history, was this Gram-negative rod was pleiomorphic, and pairs, hospitalized in the cardiologic ward for an atypical chest short chains, and filaments could be seen. Some of these constrictive pain. Initial examination showed that his organisms retained a variable amount of Gram-positive pulse was regular at 80/min and that his blood pressure stain in the end or in central portions. -

December 2018 Thomas Herchline, Editor
INFECTIOUS DISEASES NEWSLETTER December 2018 Thomas Herchline, Editor LOCAL NEWS Montgomery County Mosquito Surveillance and Control October brought an end to Public Health’s mosquito surveillance and control activities for 2018. This year, with the assistance of two Wright State University Environmental Health interns, Public Health collected 9,466 mosquitoes from 125 different trap locations in Montgomery County. This resulted in 410 mosquito pools being tested, with 71 testing positive for West Nile Virus. A mosquito pool consists of a collection of up to 50 mosquitoes that are submitted to the Ohio Department of Health laboratory for testing. State-wide there were 16,902 mosquito pools tested. In Montgomery County 17% of the mosquito pools tested positive for WNV, which was similar to the state-wide percentage (19%). There were three confirmed human cases of WNV reported in Montgomery County with a total of 57 cases occurring in 25 other counties. In response to WNV positive mosquito pools, Public Health conducted truck-mounted applications of mosquito adulticides on 8 separate occasions. There were no locally-acquired human cases of Zika Virus reported in Ohio. The mosquito species capable of spreading the Zika Virus was found in 4% of the mosquitoes collected in Montgomery County (compared to 1% statewide). Montgomery County Hepatitis A Hepatitis A outbreaks have been occurring in multiple states across the U.S., including several bordering Ohio. The Ohio Department of Health declared a statewide community outbreak for Hepatitis A on June 22. As of October 29, Ohio had 761 confirmed cases and Montgomery County had a total of 148 cases. -

ROOD3 Departments of Pharmacology' and Microbiology,2 Forsyth Dental Center, Boston, Massachusetts 021 15, and Department of Microbiology, Monash University, Clayton 31 68, Australia3 The 16s rRNA sequences of Kingella indologenes, Cardiobacterium horninis, and Bacteroides nodosus were determined by direct RNA sequencing, using a modified Sanger method. Sequence comparisons indicated that these three species represent a novel family in the gamma division of Proteobacteria. On the basis of these data, K. indologenes and B. nodosus cannot retain their current generic status as they are not closely related to other members of their assigned genera. Therefore, we propose transfer of K, indologenes to the new genus Suttonella as Suttonella indologenes and transfer of B. nodosus to the new genus Dichelobacter as Dichelobacter nodosus and assign the genera Cardiobacterium, Suttonella, and Dichelobacter to a new family, Cardiobacteriaceae, in the gamma division of Proteobacteria. Comparison of 16s rRNA sequences has proven to be goats, and cattle (33). Infected hooves are the only known extremely useful for determining phylogenetic relationships habitat of Bacteroides nodosus. -

An Unusual Case of Cardiobacterium Valvarum Causing Aortic Endograft Infection and Osteomyelitis Eric G
Hauser et al. Ann Clin Microbiol Antimicrob (2021) 20:14 https://doi.org/10.1186/s12941-021-00419-w Annals of Clinical Microbiology and Antimicrobials CASE REPORT Open Access An unusual case of Cardiobacterium valvarum causing aortic endograft infection and osteomyelitis Eric G. Hauser1, Imran Nizamuddin1* , Brett B. Yarusi1 and Karen M. Krueger2 Abstract Background: HACEK (Haemophilus spp., Aggregatibacter spp., Cardiobacterium spp., Eikenella corrodens, and Kingella spp.) group organisms are responsible for 0.8% to 6% of all infective endocarditis cases, with Cardiobacterium spp. being the third most commonly implicated HACEK microorganism. Within this genus is Cardiobacterium valvarum (C. valvarum), a novel organism described in 2004. To date, only 15 cases of C. valvarum infection have been reported in the English-language literature, and have primarily been cases of infective endocarditis in patients with valvular disease. C. valvarum has not been reported to cause infections spreading to the surrounding bone. Case presentation: We present a case of a 57-year-old man with a history of aortic dissection followed by aortic endograft replacement who presented with back pain. He was found to have radiographic evidence of an infected aortic endograft, along with vertebral osteomyelitis, discitis, and epidural phlegmon. Blood cultures identifed C. val- varum as the causative organism. The patient was treated with ceftriaxone and surgical intervention was deferred due to the patient’s complex anatomy. His course was complicated by septic cerebral emboli resulting in cerebrovascular accident. Conclusions: This case report highlights C. valvarum, a rare and emerging HACEK group microorganism that war- rants consideration in high-risk patients with evidence of subacute infection and disseminated disease.
