Title: Antimicrobial resistance in aeromonads and new therapies targeting quorum sensing
AbstractAeromonasspecies (spp.) are well-known fish pathogens, several of which have been recognized as emerging human pathogens. The organism is capable of causing a wide spectrum of diseases in humans, ranging from gastroenteritis, wound infections, and septicemia to devastating necrotizing fasciitis. The systemic form of infection is often fatal, particularly in patients with underlying chronic diseases. Indeed, recent trends demonstrate rising numbers of hospital-acquiredAeromonasinfections, especially in immuno-compromised individuals. Additionally,Aeromonas-associated antibiotic resistance is an increasing challenge in combating both fish and human infections. The acquisition of antibiotic resistance is related toAeromonas’ innate transformative properties including its ability to share plasmids and integron-related gene cassettes between species and with the environment. As a result, alternatives to antibiotic treatments are desperately needed. In that vein, many treatments have been proposed and studied extensively in the fish-farming industry, including treatments that targetAeromonasquorum sensing. In this review, we discuss current strategies targeting quorum sensing inhibition and propose that such studies empower the development of novel chemotherapeutic approaches to combat drug-resistantAeromonasspp. infections in humans. Key points• Aeromonas notoriously acquires and maintains antimicrobial resistance, making treatment options limited.• Quorum sensing is an essential virulence mechanism in Aeromonas infections.• Inhibiting quorum sensing can be an effective strategy in combating Aeromonas infections in animals and humans.  more » « less

    ABSTRACT Antibiotics are often used to treat severeVibrioinfections, with third-generation cephalosporins and tetracyclines combined or fluoroquinolones alone being recommended by the US Centers for Disease Control and Prevention. Increases in antibiotic resistance of both environmental and clinical vibrios are of concern; however, limited longitudinal data have been generated among environmental isolates to inform how resistance patterns may be changing over time. Hence, we evaluated long-term trends in antibiotic resistance of vibrios isolated from Chesapeake Bay waters (Maryland) across two 3-year sampling periods (2009–2012 and 2019–2022).Vibrio parahaemolyticus(n= 134) andVibrio vulnificus(n= 94) toxR-confirmed isolates were randomly selected from both sampling periods and tested for antimicrobial susceptibility against eight antibiotics using the Kirby-Bauer disk diffusion method. A high percentage (94%–96%) ofV. parahaemolyticusisolates from both sampling periods were resistant to ampicillin and only 2%–6% of these isolates expressed intermediate resistance or resistance to third-generation cephalosporins, amikacin, tetracycline, and trimethoprim-sulfamethoxazole. Even lower percentages of resistantV. vulnificusisolates were observed and those were mostly recovered from 2009 to 2012, however, the presence of multiple virulence factors was observed. The frequency of multi-drug resistance was relatively low (6%–8%) but included resistance against antibiotics used to treat severe vibriosis in adults and children. All isolates were susceptible to ciprofloxacin, a fluoroquinolone, indicating its sustained efficacy as a first-line agent in the treatment of severe vibriosis. Overall, our data indicate that antibiotic resistance patterns amongV. parahaemolyticusandV. vulnificusrecovered from the lower Chesapeake Bay have remained relatively stable since 2009.IMPORTANCEVibriospp. have historically been susceptible to most clinically relevant antibiotics; however, resistance and intermediate-resistance have been increasingly recorded in both environmental and clinical isolates. Our data showed that while the percentage of multi-drug resistance and resistance to antibiotics was relatively low and stable across time, someVibrioisolates displayed resistance and intermediate resistance to antibiotics typically used to treat severe vibriosis (e.g., third-generation cephalosporins, tetracyclines, sulfamethoxazole-trimethoprim, and aminoglycosides). Also, given the high case fatality rates observed withVibrio vulnificusinfections, the presence of multiple virulence factors in the tested isolates is concerning. Nevertheless, the continued susceptibility of all tested isolates against ciprofloxacin, a fluoroquinolone, is indicative of its use as an effective first-line treatment of severeVibriospp. infections stemming from exposure to Chesapeake Bay waters or contaminated seafood ingestion.

    ABSTRACT The human skin microbiome is a diverse ecosystem that can help prevent infections by producing biomolecules and peptides that inhibit growth and virulence of bacterial pathogens.Staphylococcus aureusis a major human pathogen responsible for diseases that range from acute skin and soft tissue infections to life-threatening septicemia. Its ability to form biofilms is a key virulence factor contributing to its success as a pathogen as well as to its increased antimicrobial resistance. Here, we investigated the ability of bacterial skin commensals to produce molecules that inhibitS. aureusbiofilm formation. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) identified 77 human skin microbiome bacterial isolates fromStaphylococcusandBacillusgenera. Metabolites from cell-free concentrated media (CFCM) from 26 representative isolates were evaluated for their ability to inhibit biofilm formation by both methicillin-resistant (MRSA) and methicillin-sensitive (MSSA)S. aureusstrains. CFCM, derived from most of the isolates, inhibited biofilm formation to varying extents but did not inhibit planktonic growth ofS. aureus. Size fractionation of the CFCM of threeS.epidermidisisolates indicated that they produce different bioactive molecules. Cluster analysis, based on either MALDI-TOF mass spectra or whole-genome sequencing draft genomes, did not show clear clusters associated with levels of biofilm inhibition amongS. epidermidisstrains. Finally, similar biosynthetic gene clusters were detected in allS. epidermidisstrains analyzed. These findings indicate that several bacterial constituents of the human skin microbiome display antibiofilmin vitroactivity, warranting further investigation on their potential as novel therapeutic agents. IMPORTANCEThe skin is constantly exposed to the environment and consequently to numerous pathogens. The bacterial community that colonizes healthy skin is thought to play an important role in protecting us against infections.S. aureusis a leading cause of death worldwide and is frequently involved in several types of infections, including skin and soft tissue infections. Its ability to adhere to surfaces and produce biofilms is considered an important virulence factor. Here, we analyzed the activity of different species of bacteria isolated from healthy skin onS. aureusbiofilm formation. We found that some species ofStaphylococcusandBacilluscan reduceS. aureusbiofilm formation, although a generally lower level of inhibitory activity was observed compared toS. epidermidisisolates. AmongS. epidermidisisolates, strength of activity was dependent on the strain. Our data highlight the importance of mining the skin microbiome for isolates that could help combat skin pathogens.

    The prompt appearance of multiantibiotic-resistant bacteria necessitates finding alternative treatments that can attenuate bacterial infections while minimizing the rate of antibiotic resistance development. Streptococcus pneumoniae , a notorious human pathogen, is responsible for severe antibiotic-resistant infections. Its pathogenicity is influenced by a cell-density communication system, termed quorum sensing (QS). As a result, controlling QS through the development of peptide-based QS modulators may serve to attenuate pneumococcal infections. Herein, we set out to evaluate the impact of the introduction of bulkier, nonproteogenic side-chain residues on the hydrophobic binding face of CSP1 to optimize receptor-binding interactions in both of the S. pneumoniae specificity groups. Our results indicate that these substitutions optimize the peptide–protein binding interactions, yielding several pneumococcal QS modulators with high potency. Moreover, pharmacological evaluation of lead analogs revealed that the incorporation of nonproteogenic amino acids increased the peptides’ half-life towards enzymatic degradation while remaining nontoxic. Overall, our data convey key considerations for SAR using nonproteogenic amino acids, which provide analogs with better pharmacological properties.

    ABSTRACT The increasing threat of antibiotic resistance underscores the urgent need for innovative strategies to combat infectious diseases, including the development of antivirulants. Microbial pathogens rely on their virulence factors to initiate and sustain infections. Antivirulants are small molecules designed to target virulence factors, thereby attenuating the virulence of infectious microbes. The bacterial type IV pilus (T4P), an extracellular protein filament that depends on the T4P machinery (T4PM) for its biogenesis, dynamics and function, is a key virulence factor in many significant bacterial pathogens. While the T4PM presents a promising antivirulence target, the systematic identification of inhibitors for its multiple protein constituents remains a considerable challenge. Here we report a novel high‐throughput screening (HTS) approach for discovering T4P inhibitors. It usesPseudomonas aeruginosa,a high‐priority pathogen, in combination with its T4P‐targeting phage, φKMV. Screening of a library of 2168 compounds using an optimised protocol led to the identification of tuspetinib, based on its deterrence of the lysis ofP. aeruginosaby φKMV. Our findings show that tuspetinib also inhibits two additional T4P‐targeting phages, while having no effect on a phage that recognises lipopolysaccharides as its receptor. Additionally, tuspetinib impedes T4P‐mediated motility inP. aeruginosaandAcinetobacterspecies without impacting growth or flagellar motility. This bacterium‐phage pairing approach is applicable to a broad range of virulence factors that are required for phage infection, paving ways for the development of advanced chemotherapeutics against antibiotic‐resistant infections.

    ABSTRACT Rhizopus microsporusis a necrotrophic post-harvest pathogen that causes significant economic losses in the agricultural sector. To explore alternatives to conventional management strategies for the mitigation of post-harvest infections, we investigated the potential of two previously identified endophyticBacillus velezensisstrains as biological control agents. Throughin vitroandin vivoexperiments, we examined the mechanisms of biocontrol displayed by twoB. velezensisstrains (KV10 and KV15) against threeR. microsporusstrains (W2-50, W2-51, and W2-58).In vitroassays assessed co-cultivability and the inhibitory effects ofB. velezensisagainstR. microsporus. The results demonstrated strain-specific antifungal activity with a reduction in fungal growth across treatments. Further analysis revealed that volatile organic compounds produced byB. velezensiscontributed to its antifungal properties. To evaluate the biocontrol efficacyin vivo, tomato fruits were inoculated withR. microsporusand subsequently treated withB. velezensis. The results support the strain-specific reduction in tomato spoilage, yielding various spoilage rates observed across treatments. Our findings highlight the potential ofB. velezensisas a promising biocontrol agent for the management ofR. microsporuspost-harvest infections in tomatoes. Further research is warranted to optimize the applicationof B. velezensisas a sustainable and environmentally friendly approach for controlling post-harvest diseases in tomatoes.IMPORTANCEOur study shows the significance of improving sustainable agriculture by offering an alternative to the use of chemical fungicides in post-harvest applications. Opportunistic fungal pathogens likeRhizopus microsporuscan have detrimental effects on post-harvest commodities like tomatoes. Post-harvest fungal infections are mainly controlled by chemical fungicides that pose health risks to humans and the environment. Utilizing biocontrol agents provides an environmentally safe alternative. Understanding the mechanisms of biocontrol employed by beneficial bacteria likeBacillus velezensison fungal pathogens gives insight into safer, more environmentally friendly alternatives to protect food crops. Our results suggest that targeted microbial solutions can mitigate post-harvest losses.
