Enterobacter cloacae is an opportunistic pathogen that causes hospital-acquired infections in immunocompromised patients. Here, we describe vB_EclM_CIP9, a novel Enterobacter phage that infects a multidrug-resistant isolate of E. cloacae. Phage vB_EclM_CIP9 is a myovirus that has a 174,924-bp genome, with 296 predicted open reading frames.

Globally, carbapenemase-producing Enterobacterales (CPE) cause life-threatening, hospital-acquired infections in people, and have been reported recently among veterinary patients. Organisms that produce a Klebsiella pneumoniae carbapenemase (KPC) are one of the most common CPE isolated from people but have been reported only rarely in animals. We characterized 2 KPC-producing Enterobacterales isolated from companion animal rectal swabs during the response to an outbreak caused by a strain of blaNDM-5 Escherichia coli. Both isolates were characterized by whole-genome sequencing (WGS) and analysis. The first isolate (case A) was from an immunosuppressed 6-y-old Yorkshire Terrier and was identified as E. coli (ST372) with a blaKPC-18 gene and an IncFII plasmid. The second isolate (case B) was from a 3-y-old Labrador Retriever with acute diarrhea and was identified as Citrobacter koseri with a blaKPC-2 gene, multiple plasmids (ColRNAI, pKPC-CAV1193), and a putative enterotoxin gene ( senB). Further research is needed to determine what role animals might play in the epidemiology of CPE in communities. It is imperative that all CPE isolated from companion animals be fully characterized by WGS and the associated case examined. All veterinary isolates should be sequenced and shared for surveillance, monitoring, and investigation purposes.

Abstract Catheter associated urinary tract infections (CAUTIs) are an endemic problem in the American medical system, causing nearly 32% of all hospital-acquired infections (HAIs) [1]. Novel antimicrobial coatings for catheters, consisting of metal powders (Ag/Ag2O) and polydimethylsiloxane (PDMS), have recently been developed to combat this problem [2,3]. The active ingredients in these coatings were modeled using simplified assumptions in both ANSYS Maxwell and Quantum Espresso to determine the electric field strength at various particle radii. SEM/EDX analysis of the Ag/Ag2O coating was also performed to simulate the particles in ANSYS and provide comparison between idealized models and actual particle geometries.

Hospital-acquired infections have become a major challenge which threaten the hospitalized patients’ safety. The presence of nosocomial pathogens is generally reported in connection with solid surfaces near patient environments. These surfaces become significant sources of transmission and lead most often to the contamination and cross-contamination of nosocomial pathogens to the patients and staff. This paper investigates strategies to apply beneficial bacteria on viscose-based nonwoven wipes and the viability of these beneficial bacteria on the wipes along with characterization of the physical properties of the wipes. Major findings include that it is possible to produce dry wipes which contain an adequate number of beneficial bacteria or spores. After these wipes are wetted, they can release a certain number of bacteria from the wetted wipes. These released beneficial bacteria can inhibit pathogens by growing and colonizing on the wiped surfaces.

Staphylococcus epidermidis is a leading cause of hospital-acquired infections, mostly associated with the use of medical devices in seriously ill or immunocompromised patients. Currently, the clonal characteristics of S. epidermidis in the hospital environment in China are unknown; neither is it known why these sequence types are easily disseminated in the hospital setting. In this study, multilocus sequence typing (MLST) was employed for the clonal analysis of 80 S. epidermidis isolates collected from patients with S. epidermidis infections. MLST revealed a total of 16 different sequence types among these isolates. ST2, which contained exclusively ica-positive, IS256-positive and biofilm-forming isolates, represented the majority of clinical strains tested. Of the S. epidermidis strains circulating in the hospital environment in China, as many as 96.25 % are resistant to meticillin. Four staphylococcal chromosomal cassette mec (SCCmec) types were identified among the total 80 S. epidermidis isolates, none of the strains carried an SCCmec I cassette. All of the ST2 isolates carried the SCCmec type III cassette. Taken together, the combination of biofilm-forming ability and antibiotic resistance helps ST2 become successfully established within nosocomial environments, and promotes the device-related infection and bacteraemia.
