Dr. Becca Bruning, Infectious Diseases Pharmacy Specialist at the Moffitt Cancer and Research Institute in Tampa, FL, takes a deep dive into the subject of resistance mechanisms for specific gram negative bacteria. Dr. Bruning begins her talk by discussing the primary resistance mechanisms, including porin channels, efflux pumps, and other target sites. Extended spectrum beta-lactamases (ESBLs) are next covered, including typical bacterial species, identification techniques, ESBL testing, and the use of Piperacillin-tazobactam and carbapenems. Next, Dr. Bruning mentions AmpC-type resistance, and identifies the “HECKYES” bacteria. Pharmacokinetic and phamacdynamic considerations are explored, and specific antimicrobial agents are discussed. Lastly, Dr. Bruning covers the use of carbapenemase testing including the modified hodge test and the Carba-R test.

In this episode, Martin talks to Cansu Cimen, a researcher at University Hospitals Groningen in the Netherlands, about a recent paper that documents an outbreak and in particular the critical role of next-generation sequencing (NGS) in tracking and controlling the transmission of MDROs via contaminated duodenoscopes. Focusing on an outbreak linked to ESBL-producing Citrobacter freundii and Klebsiella pneumoniae after endoscopic retrograde cholangiopancreatography (ERCP), standard culture methods failed to detect contamination. After many negative cultures using established methods, destructive dismantling of the implicated scope revealed contamination on hard-to-clean components, highlighting NGS as an effective tool for identifying pathogen transmission pathways.

From generating 150 liters-worth of E. coli to the first X-ray crystallography of an ESBL, Drs. Robert Bonomo, Ryan Shields (@ryankshields), and Erin McCreary (@ErinMcCreary) take a deep dive into beta-lactamases like AmpCs, KPCs, and more.

We're all racing neck and neck against antimicrobial resistance - trying to preserve antibiotics for use in the most critical situations. This equine specialist pinpoints actions horse owners and veterinarians can take to minimize spread of resistant pathogens in horse populations and facilities. With fewer anti-microbials in our equine veterinary toolkit, it is essential that we learn all we can about how antimicrobial resistant pathogens travel between horses and their handlers. Without being able to identify and track antibiotic resistant bacteria, we are left in the dark when we try to adjust our management of our animals to minimize disease and to save these valuable medications for situations where they are absolutely necessary. Dr. Maud de Lagarde is a researcher and diplomate of the American College of Veterinary Internal Medicine who studies the movement of antimicrobial resistant genes in bacterial populations that affect horses in both Quebec and France. She is specifically interested in their route of dissemination to develop strategies to prevent antimicrobial resistance, and her work highlights some interesting intervention points for horse owners and veterinarians alike.

Nous sommes tous engagés dans une course contre la résistance aux antibiotiques et nous essayons de préserver l'efficacité de ces médicaments pour pouvoir continuer à les utiliser dans les situations les plus critiques. Cette spécialiste en médecine équine propose aux propriétaires de chevaux et aux vétérinaires équins des mesures qui peuvent être utilisées pour réduire la propagation de bactéries pathogènes résistantes au sein de la population équine et dans les écuries. Étant donné la réduction du nombre d'antibiotiques disponibles dans la trousse médicale des vétérinaires équins, il est essentiel que ces derniers aient accès à un maximum de connaissances concernant la façon dont les bactéries pathogènes résistantes aux antibiotiques peuvent se transmettre entre les chevaux et leurs propriétaires. Si les vétérinaires équins ne savent pas comment identifier et suivre les mouvements des bactéries résistantes aux antibiotiques, il leur est difficile d'adapter la gestion de leurs cas pour réduire le risque de maladies et réserver ces médicaments importants aux situations pour lesquelles ils sont absolument nécessaires. Dre Maud de Lagarde est chercheure et diplomée du Collège américain de médecine interne vétérinaire (ACVIM). Elle étudie les mouvements des gènes de résistance aux antibiotiques dans les populations bactériennes retrouvées chez les chevaux au Québec et en France. Elle s'intéresse particulièrement à la façon dont ces gènes se propagent afin de développer des stratégies de prévention de la résistance. Son travail souligne des possibilité d'interventions concrètes pour les propriétaires de chevaux et leurs vétérinaires.

Join us with our guest: Maureen Spencer, RN, M.Ed., CIC joining us to discuss an array of important topics: 1. Overuse and inappropriate prescribing of antibiotics worldwide is leading to the global healthcare issue of antibiotic resistance. 2. Empiric antibiotics are used consistently in healthcare when infection is suspected 3. Empiric antibiotics are prescribed to cover gram positive, gram negative and yeast infections until the final lab result is available 4. Overuse of antibiotics adversely effect the normal flora and microbiome in the body depleting colonies of bacteria that are necessary for digestion and protection. 5. When the microbiome is depleted other resistant species overgrow on the skin and in the systems of the body, especially the gut. 6. Multiple Drug Resistant organisms MDRO include MRSA, VRE, ESBL and CRE that will grow in patients who have been on antibiotics AND MUCH MORE.

Dr. Bachmeier presents an up-to-date review of newer-generation antimicrobials designed to be effective against infections with multiple drug-resistant pathogens. He first reviews the different types of extended-spectrum beta-lactamase (ESBL) resistance. He then discusses the significance of Carbapenemase-producing enterobacteriaceae and ESBL producing E coli, Klebsiella pneumonia, and Pseudomonas aeruginosa strains. Such organisms have become increased threats to our patients over the last two decades while new drug approvals have dwindled. Dr. Bachmeier reviews Ceftolozane-tazobactam, Ceftazidime-avibactam and their current indications. He then reviews Meropenem-vaborbactam and its utility in the treatment of Klebsiella pneumonia carbabenemase (KPC) infections. He then discusses imipenem-relebactam and its advantages in the treatment of MDR gram-negative infections. Lastly, he reviews plazomycin, eravacycline, and Cefiderocol.

Join the EMGuideWire crew once again for this month's series on Sepsis in honor of Sepsis Awareness month. Episode 3 will cover antibiotic use and selection. Antibiotics for Sepsis Take a history and perform a chart biopsy first! Consider past infections, bug susceptibilities, healthcare acquired vs. community acquired infection, foreign travel, and comorbidities.  Always check local antibiogram and prior culture results. Septic shock - Start broad spectrum antibiotics within 1 hour. Stable patient - find the source! UA, CXR, and a good skin exam are fast and can help guide antibiotic choice. Remember some patients need surgical management!  Antibiotic choice in septic shock. 1st agent - Piperacillin/Tazobactam (covers GP/GN + Pseudo)  2nd agent - Choose based on patient characteristics Ceftriaxone - simple community acquired infections. Vancomycin - covers MRSA. Meropenem - use for patients with a hx of ESBL. Flagyl + cefepime/meropenem - Use for intra-abdominal infections. Clindamycin - Useful for skin infections (toxin suppression).  Cefazolin - IV line infections, endocarditis, soft tissue infections w/o MRSA (covers MSSA, GAS, GBS).  Summarized by: Travis Barlock, MD PGY-1 References: Alam N et al. 2018.

Como nota interesante para los infectologos, a causa de la tuberculosis estuvo desde los cinco años hasta los 9 recluida en casa dedicándose  a leer y escribir La Frase dice:   “La vida es un pequeño espacio de luz entre dos nostalgias: la de lo que aun no has vivido y al de lo que ya no vas a poder vivir. Y el momento justo de la acción es tan confuso, tan resbaladizo y tan efímero que lo desperdicias mirando con aturdimiento alrededor”

Protect Your Kids at Petting Zoos From Drug Resistant BacteriaShow Notes:A new study finds petting zoos can be breeding grounds for drug resistant bacteria (MDR) including e coli. These bacteria can place anyone touching animals at risk, particularly young children.This study was done by researchers from Ariel University in Israel. They choose eight petting zoos at random, collecting fecal matter samples and swabs from fur, skin, and feathers from 228 animals representing 42 species. Of particular interest were two bacteria types, extended spectrum beta-lactamase (ESBL) and AmpC-producing Enterobacteriaceae (AmpC-E). These bacteria are known to be highly resistant to antibiotics.About 12% of animals were colonized with at least one of the bacterial strains. Researchers discovered 35 bacterial species including two strains of e coli. E coli can cause serious The authors found that nearly 1 in 8 animals (12%) were found to be colonized with at least one of the two antibiotic-resistant bacterial strains, with 35 different recovered species of bacteria. A quarter of animals that tested positive for drug-resistant bacteria had more than one bacterial strain, including two e. coli strains. E coli can cause serious diarrhea and other infections.According to researchers, children are at elevated risk of illness from these pathogens. One of the Researchers Speaks:Professor Shiri Navon-Venezia at Ariel University, one of the researchers, comments,“Our findings demonstrate that animals in petting zoos can result in shedding and transmission of MDR pathogens that may cause illness for human visitors, even when the animals appear healthy,”She continues (note: the professor was identified as "he" in the audio. My apology for the error),“We recognize the high educational and emotional value of petting zoos for children, therefore, we strongly recommend that petting zoo management teams implement a strict hygiene and infection control policy, together with rationalized antibiotic policy, in order to reduce the risk of transmission between animals and visitors.”Common Sense PrecautionsIf you take your kids or grandkids to petting zoos, apply these common sense precautions:- No food or drink consumption by kids until after they have visited and touched all of the animals AND HAVE WASHED THEIR HANDS AND EXPOSED SKIN COMPLETELY.- Don’t let them touch any objects that will be touched by other people during the time they’re interacting with petting zoo animals.- If there is any indication an animal is being treated with antibiotics, don’t let children touch or come near that animal.- As soon as possible, change children’s clothing. Place the clothing items directly in the washer and wash the clothes in hot water and dry with high heat.- Ensure YOU wash your hands and exposed skin after touching clothes worn by children at the petting zoo.For more, “Safe Living Today” episodes, visit us at www.SafeLivingToday.com.Sources and Resources“Petting Zoos May Be Crawling With Drug-Resistant Bacteria, Putting Kids At Risk”. https://www.studyfinds.org/petting-zoos-multi-drug-resistant-bacteria/.European Society of Clinical Microbiology and Infectious Diseases.

Aunque en el tratamiento de infecciones causadas por microorganismos productores de beta-lactamasa de espectro extendido (BLEE) se favorece tradicionalmente el uso de carbapenemicos existe la esperanza que otros antibióticos puedan ser efectivos. De eso se trata el Estudio Merino, cuyos resultados fueron dados a conocer recientemente en Europa.  Referencias:    Vardakas KZ y colaboradores.

Kirurgia, syöpähoidot ja elinsiirrot ryytyvät, jos bakteereja karaistaan vielä paremmin antibiootteja kestäviksi. Kaikissa näissä tarvitaan antibiootteja tulehdusten varalta. Nyt bakteerit totutetaan antibiootteihin, kun turhia kuureja syödään jatkuvasti. Matkailija kerää mukaansa superbakteereita, jos ottaa antibiootteja riskialueilla. Kuuri tappaa lälläribakteerit ja tekee tilaa lääkkeitä kestäville superbakteereille. Antibiootteja nappaava matkailija valikoi riskialueelta tuliaisiksi kaikkein vastustuskykyisimmät ESBL-superbakteerit. Ja resistenssiongelma pahenee. Studiossa Leena Mattila sekä professorit Anu Kantele ja Pentti Huovinen.

Shiga toxin producing E. coli (STEC) can occur either as part of the normal intestinal gut flora or as pathogenic agents in animals and humans causing serious disease in humans. In the present study we determined the frequencies of resistance against 14 different antimicrobial agents of in total 235 STEC isolates from farm cattles, wild ruminants and food products. This susceptibility testing was performed using broth microdilution method. Overall, the most frequent resistances were detected against streptomycin, sulfonamides, and tetracycline. Furthermore, 30 of the 36 resistant isolates detected in this study were multi drug resistant against two or more antimicrobial agents. Another focus of this study was the detection of potential ESBL producing isolates, which show resistance to the enlarged spectrum of β‐lactam antibiotics such as cephalosporins of the 3rd and 4th generation. Therefore, all STEC isolates were examined both phenotypically and genotypically using microdilution method and PCR, respectively. Performing a sequential analysis the majority (8/10) of those isolates were non‐ESBL blaTEM‐1. However, using microdilution method detectably minor susceptibility to 3rd and 4th generation cephalo‐sporins in five (2.1%) out of the 235 studied STEC isolates was observed. Overall, antimicrobial susceptibility of STEC isolates could be detected in isolates from domestic ruminants as well as in a very small proportion of wild ruminant isolates.
