[PMID: 38313867 PMCID: PMC10830907 DOI: 10.1155/2024/2478832] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 01/11/2024] [Accepted: 01/17/2024] [Indexed: 02/06/2024] Open
Abstract
Peritonitis is the major complication of peritoneal dialysis (PD) patients. Staphylococcus is the leading causative organism of PD-related peritonitis. However, there were more reports of unusual organisms causing peritonitis. Clinical features, management, and outcome of peritonitis from unusual organisms are important information. We reported herein a 72-year-old female patient who presented with fever, abdominal pain, and cloudy dialysate for 3 days. Upon admission, ceftazidime and vancomycin were given intraperitoneally. A preliminary report of blood and PD fluid culture showed the presence of Gram-positive bacilli. Her clinical status improved 48 hours after the commencement of the antibiotics. Subsequently, culture reports of blood and PD fluid showed Lysinibacillus sphaericus which was susceptible to vancomycin at a minimal inhibitory concentration of less than 0.25 μg/mL. The patient was given intraperitoneal vancomycin for a total of 14 days. Then, the PD effluent was clear, and its cell count was below 100 cells/mm3 in 3 days. The patient did not have a recurrence of peritonitis after antibiotic discontinuation. The possibility of this organism infection is environmental contamination related to the patient's gardening activities.

Abstract
Lysinibacillus sphaericus, as an insect pathogen, is a ubiquitous Gram-positive bacterium present in the environment. It is often considered to be contaminating bacteria. L. sphaericus has been reported to cause infectious diseases in humans relatively rarely. We report a rare case of bacteremia due to L. sphaericus in a person living with HIV, which is also the first reported case of bacteremia caused by L. sphaericus in China. L. sphaericus easily causes infection in immunocompromised individuals. We found that L. sphaericus and Lysinibacillus fusiformis could not be distinguished by their 16S ribosomal RNA gene sequence. We performed a genome-wide analysis of the isolated strains of this case and predicted the virulence factors. Finally, L. sphaericus was confirmed. According to antimicrobial susceptibility test, the strain was found to be sensitive to levofloxacin and vancomycin but resistant to penicillin. Greater attention to L. sphaericus infection should be paid and immunocompromised populations should be protected from L. sphaericus infection.

Abstract
We herein report a case of peritoneal dialysis-associated peritonitis caused by Lysinibacillus sphaericus in a 40s-year-old patient. Treatment was initiated with intermittent intraperitoneal cefazolin and ceftazidime. Later, both peritoneal dialysate and blood cultures detected L. sphaericus, so the antibiotic was changed to ampicillin (ABPC). The patient was treated with a combination of intraperitoneal intermittent and intravenous ABPC for 7 days, followed by 14 days of amoxicillin. The patient experienced no adverse events and no recurrence for 30 days. The patient had four dogs, and the infection was deemed likely to have been caused by environmental contamination and inadequate catheter replacement.

Abstract
INTRODUCTION It is recognized that mobile phones may play a role in microorganism transmission and that hand hygiene, is considered the most important action for preventing infections and the spread of pathogens. The objective of this study was to determine presence and circulation bacteria on hands and mobile phones capable of causing infections in people and also determine if disinfection with gel-alcohol is useful to reduce the bacterial colonization. METHODS The bacterial evaluation included 596 hands of participants and 256 mobile phones. Isolated colonies were identified by biochemical test and confirmed by gene 16S rRNA sequencing. Antimicrobial susceptibility was performed using the automated instrument Vitek®2-Compact and disk-diffusionmethod. RESULTS In total, 92.9% of mobile phones and 98.3% of participants in study demonstrated evidence of bacterial contamination with different types of bacteria. Surprisingly, we observed that 18.6% plaques inoculated with disinfected fingers showed bacterial growth. In general, Gram negative isolates showed resistance to a higher number of antibiotics tested than Gram positive isolates. CONCLUSIONS Our results could help to raise awareness in our society about the importance of hand hygiene, as well as frequently used devices, reducing bacterial contamination and limiting the possibility of transmission of resistant multi-drug bacteria.

Abstract
PURPOSE This study aimed to investigate the gut microbiome composition in pregnant women with digestive diseases to analyze the relationships between the microflora changes and digestive diseases during pregnancy. METHODS Fecal samples obtained from 71 pregnant women [six acute fatty liver (AF group), 21 constipation (C group), 24 excessive vomiting (V group) and 20 normal pregnancy (CP group)] and 26 non-pregnant (NP group) women were subjected to 16 s rRNA sequencing. Differential analysis of intestinal flora at the genera level was performed. RESULTS The relative abundance of Coprobacillus, Acinetobacter, Enterococcus, Weissella and Lysinibacillus was increased in the digestive diseases (AF, C and V) groups compared with CP group, whereas that of five common genera, including Terrisporobacter, Dysgonomonas, Adlercreutzia, Fusicatenibacter and Blautia, was decreased in digestive diseases groups. Additionally, in digestive diseases (AF, C and V) groups, the abundance of 13 common genera, such as Carnobacterium, Coprobacillus and Psychrobacter, was higher than NP group, whereas that of 27 common genera, such as Blautia and Terrisporobacter, was lower than NP group. About 69 genera were differentially abundant between AF and C groups; two genera (Aerococcus and Senegalimassilia) were identified between AF and V groups; moreover, total 63 genera were obtained between C and V groups. CONCLUSION Our data revealed that the abundance of Acinetobacter, Enterococci, Paenibacillus, Blautia and Collinsella might be associated with the digestive diseases during pregnancy. These findings further supported the idea that targeting the gut microbiota could be a new prevention or therapeutic approach for improving digestive diseases during pregnancy.

Abstract
Lysinibacillus massiliensis, formerly Bacillus massiliensis, is an environmental Gram-positive bacillus that is generally non-pathogenic. Rare case reports in immunosuppressed patients have described sepsis with this organism. In this study, we report a case of L massiliensis as a cause of infectious panniculitis mimicking erythema nodosum after infusion of autologous adipose-derived stem cells in an immunosuppressed patient with refractory Crohn’s disease. This case highlights the importance of care providers to consider exposures and host factors when interpreting culture results with otherwise benign organisms.

Abstract
Strain FF3(T) was isolated from the skin-flora of a 39-year-old healthy Senegalese man. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry did not allow any identification. This strain exhibited a 16S rRNA sequence similarity of 96.8% with Bacillus massiliensis, the phylogenetically closest species with standing nomenclature. Using a polyphasic study made of phenotypic and genomic analyses, strain FF3(T) was Gram-positive, aeroanaerobic and rod shaped and exhibited a genome of 4 068 720 bp with a G+C content of 37.03% that coded 3982 protein-coding and 67 RNA genes (including four rRNA operons). On the basis of these data, we propose the creation of Bacillus ndiopicus sp. nov.

Abstract
Lysinibacillus and Paenibacillus are pervasive bacteria rarely associated with human disease. Less sophisticated microbiology techniques may frequently incorrectly identify these genera as Bacillus spp., often regarded as environmental contamination. This report describes a case of severe sepsis due to persistent Lysinibacillus and Paenibacillus bacteremia, identified by matrix-assisted laser desorption and ionization time-of-flight mass spectroscopy and 16S rRNA gene sequencing.

Abstract
Background.In 2007–2008, several US hospitals reported summertime increases in the number of clinical blood cultures positive forBacillusspecies, which are common environmental bacteria.Objective.To investigate increased rates of isolation ofBacillusspecies from blood cultures, identify risk factors, and recommend control strategies.Design.Survey and case-control study.Setting.Multiple hospitals, including a cancer center.Methods.We surveyed 24 facilities that reported increases. We also conducted a field investigation at a hospital with a high rate, reviewing charts, collecting clinical and environmental isolates, and observing infection control procedures. A case-control study compared inpatient case patients who had any blood culture positive forBacilluswith unmatched control patients who had a blood culture with no growth during June-August 2008.Results.Among surveyed facilities, mean monthly rates rose from 25 to a peak of 75Bacillus-positive blood cultures per 10,000 blood cultures performed during the period June-August. At the hospital where the case-control investigation was conducted, for most case patients (75%), theBacillus-positive blood cultures represented contamination or device colonization rather than infection. We enrolled 48 case patients and 48 control patients; in multivariate analysis, only central venous access device use was significantly associated with case status (odds ratio, 14.0;P< .01). Laboratory testing identified at least 12 differentBacillusspecies (non-anthracis) among the isolates. Observation of infection control procedures revealed variability in central line care and blood sample collection techniques.Conclusions.Periodic increases in the environmental load ofBacillusspecies may occur in hospitals. Our investigation indicated that at one facility, these increases likely represented a pseudo-outbreak ofBacillusspecies colonizing central venous lines or their accessories, such as needleless connector devices. Vigilant attention should be paid to infection control practices when collecting blood samples for culture, to minimize the risk of contamination by environmental microorganisms.

Abstract
BACKGROUND The risk of developing a tunnelled central venous catheter (CVC)-related infection ranges between 0.1 and 2.3 per 1000 catheter days for children with cancer. These infections are difficult to treat with systemic antibiotics (salvage rate 24% - 66%) due to biofilm formation in the CVC. Lock treatments can achieve 100 - 1000 times higher concentrations locally without exposure to high systemic concentrations. OBJECTIVES Our objective was to investigate the efficacy of antibiotic and other lock treatments in the treatment of CVC-related infections in children with cancer compared to a control intervention. We also assessed adverse events of lock treatments. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, issue 3, 2011), MEDLINE/PubMed (1945 to August 2011) and EMBASE/Ovid (1980 to August 2011). In addition we searched reference lists from relevant articles and the conference proceedings of the International Society for Paediatric Oncology (SIOP) (from 2006 to 2010), American Society of Clinical Oncology (ASCO) (from 2006 to 2010), the Multinational Association of Supportive Care in Cancer (MASCC) (from 2006 to 2011), the American Society of Hematology (ASH) (from 2006 to 2010) and the International Society of Thrombosis and Haematology (ISTH) (from 2006 to 2011). We scanned the ISRCTN Register and the National Institute of Health Register for ongoing trials (www.controlled-trials.com) (August 2011). SELECTION CRITERIA Randomised controlled trials (RCTs) and controlled clinical trials (CCTs) comparing an antibiotic lock or other lock treatment (with or without concomitant systemic antibiotics) with a control intervention (other lock treatment with or without concomitant systemic antibiotics or systemic antibiotics alone) for the treatment of CVC-related infections in children with cancer. For the description of adverse events, cohort studies were also eligible for inclusion. DATA COLLECTION AND ANALYSIS Two authors independently selected studies, extracted data and performed 'Risk of bias' assessments of included studies. Analyses were performed according to the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS Two RCTs evaluated urokinase lock treatment with concomitant systemic antibiotics (n = 56) versus systemic antibiotics alone (n = 48), and one CCT evaluated ethanol lock treatment with concomitant systemic antibiotics (n = 15) versus systemic antibiotics alone (n = 13). No RCTs or CCTs evaluating antibiotic lock treatments were identified. All studies had methodological limitations and clinical heterogeneity between studies was present. We found no evidence of significant difference between ethanol or urokinase lock treatments with concomitant systemic antibiotics and systemic antibiotics alone regarding the number of participants cured, the number of recurrent CVC-related infections, the number of days until the first negative blood culture, the number of CVCs prematurely removed, ICU admission and sepsis. Not all studies were included in all analyses. No adverse events occurred in the five publications of cohort studies (one cohort was included in two publications) assessing this outcome; CVC malfunctioning occurred in three out of five publications of cohort studies assessing this outcome. AUTHORS' CONCLUSIONS No significant effect of urokinase or ethanol lock in addition to systemic antibiotics was found. However, this could be due to low power or a too-short follow-up. The cohort studies identified no adverse events; some cohort studies reported CVC malfunctioning. No RCTs or CCTs were published on antibiotic lock treatment alone. More well-designed RCTs are needed to further explore the effect of antibiotic or other lock treatments in the treatment of CVC-related infections in children with cancer.

J Microbiol Methods 2007; 71:147-55. [PMID: 17889384 DOI: 10.1016/j.mimet.2007.08.006] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2007] [Revised: 08/16/2007] [Accepted: 08/20/2007] [Indexed: 10/22/2022]
Abstract
In an effort to overcome historical problems associated with the isolation of Bartonella species from animal and human blood samples, our laboratory developed a novel, chemically modified, insect-based, liquid culture medium (Bartonella alpha-Proteobacteria growth medium, BAPGM). In this study, we describe the isolation of non-Bartonella bacteria from aseptically obtained human blood and tissue samples that were inoculated into BAPGM pre-enrichment culture medium, and were obtained during attempts to define each individuals Bartonella infection status. After incubation for at least 7 days in liquid BAPGM, pre-enriched inoculums were sub-cultured onto a BAPGM/blood agar plate. Bacterial DNA was extracted from pooled plated colonies and amplified using conventional PCR targeting the 16S rRNA gene. Subsequently, amplicons were cloned, sequenced and compared to GenBank database sequences using the BLAST program. Regardless of the patient's Bartonella status, seventeen samples generated only one 16S rDNA sequence, representing the following genera: Arthrobacter, Bacillus, Bartonella, Dermabacter, Methylobacterium, Propionibacterium, Pseudomonas, Staphylococcus and bacteria listed as "non-cultured" in the GenBank database. Alkalibacterium, Arthrobacter, Erwinia, Kineococcus, Methylobacterium, Propionibacterium, Sphingomonas, and Staphylococcus were isolated from nine Bartonella-infected individuals. Co-isolation of Acinetobacter, Sphingomonas, Staphylococcus spp. and bacteria listed as "non-cultured" in the GenBank database was achieved for four samples in which Bartonella spp. were not detected. Despite the phylogenetic limitations of using partial 16S rRNA gene sequencing for species and strain identification, the investigational methodology described in this study may provide a complementary approach for the isolation and identification of bacteria from patient samples.

Abstract
Daptomycin inhibited 67 of 70 clinical isolates of Bacillus species at < or =1 microg/ml and 100% of them at < or =2 microg/ml. It showed bactericidal activity similar to that of ciprofloxacin against vegetative cells but not against spores. For 2 strains, the ciprofloxacin MICs were >4 g/ml, and 10 strains were resistant to erythromycin.

Abstract
Between April 2000 and May 2005, 350 bacteraemic episodes occurred among patients treated in our haematology unit. Two hundred and twenty-eight of these episodes were caused by Gram-positive pathogens, most commonly coagulase-negative staphylococci and Staphylococcus aureus. One hundred and twenty-two episodes were due to Gram-negative pathogens, with a predominance of Escherichia coli, Acinetobacter baumannii and Pseudomonas aeruginosa. Bacillus bacteraemias constituted 12 of these episodes occurring in 12 patients, and accounted for 3.4% of all bacteraemic episodes. Of the 12 strains evaluated, seven were Bacillus licheniformis, three were Bacillus cereus and two were Bacillus pumilus. Seven episodes presented with bloodstream infection, three with pneumonia, one with severe abdominal pain and deterioration of liver function, and one with a catheter-related bloodstream infection. B. licheniformis was isolated from five patients who had been hospitalized at the same time. This outbreak was related to non-sterile cotton wool used during skin disinfection. B. cereus and B. licheniformis isolates were susceptible to cefepime, carbapenems, aminoglycosides and vancomycin, but B. pumilus isolates were resistant to all antibiotics except for quinolones and vancomycin. Two deaths were observed. In conclusion, Bacillus spp. may cause serious infections, diagnostic and therapeutic dilemmas, and high morbidity and mortality in patients with haematological malignancies. Both B. cereus and B. licheniformis may be among the 'new' Gram-positive pathogens to cause serious infection in patients with neutropenia.

Abstract
An unidentified Gram-negative-staining, aerobic, rod-shaped, spore-forming bacterium was isolated from a sample of cerebrospinal fluid. Based on comparative analysis of 16S rRNA gene sequences and phenotypic characteristics, the novel isolate was included in the Bacillus sphaericus-like group. The isolate was closely related to Bacillus odysseyi and Bacillus silvestris, with 96.2 and 94.4 % 16S rRNA gene sequence similarity, respectively. The major fatty acid was iso-C15 : 0 (48 %). The name Bacillus massiliensis sp. nov. is proposed for the novel isolate, with strain 4400831T (=CIP 108446T=CCUG 49529T) as the type strain.
