Abstract
Bovine mastitis is a widespread infectious disease with a significant economic burden, accounting for 80 % of the antibiotic usage in dairy animals. In recent years, extensive research has focused on using biomimetic approaches such as probiotics, bacteriocins, bacteriophages, or phytochemicals as potential alternatives to antibiotics. The local administration of therapeutic molecules through the intramammary route is one of the most commonly strategies to manage bovine mastitis. This review highlights the most important findings in this field and discusses their local application in mastitis therapy. In contrast to antibiotics, the proposed alternatives are not limited to promote bacterial death but consider other factors associated to the host microenvironments. To this end, the proposed biomimetic strategies can modulate different stages of infection by modifying the local microbiota, preventing oxidative stress, reducing bacterial adhesion to epithelial cells, modulating the immune response, or mediating the inflammatory process. Numerous in vitro studies support the antimicrobial, antibiofilm or antioxidant properties of these alternatives. However, in vivo studies incorporating these components within pharmaceutical formulations with potential clinical application are limited. The development of secure, stable, and effective drug delivery systems based on the proposed options is necessary to achieve real alternatives to antibiotics in the clinic.

Zhao Y, Feng L, Zhou B, Zhang X, Yao Z, Wang L, Wang Z, Zhou T, Chen L. A newly isolated bacteriophage vB8388 and its synergistic effect with aminoglycosides against multi-drug resistant Klebsiella oxytoca strain FK-8388. Microb Pathog 2023; 174:105906. [PMID: 36494020 DOI: 10.1016/j.micpath.2022.105906] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Revised: 11/24/2022] [Accepted: 11/24/2022] [Indexed: 12/12/2022]
Abstract
The bacteriophage vB8388 can lyse multi-drug resistant Klebsiella oxytoca strain FK-8388 and maintain stability in a wide range of temperatures (from 4 °C to 80 °C) and pHs (3-11). Bioinformatics analysis showed that vB8388 is a linear double-stranded DNA virus that is 39,750 long with 50.65% G + C content and 44 putative open reading frames (ORFs). Phage vB8388 belongs to the family Autographviridae and possesses a non-contractile tail. The latency period of vB8388 was approximately 20 min. The combination of phage vB8388 and gentamicin, amikacin, or tobramycin could effectively inhibit the growth of K. oxytoca strain FK-8388, with a decrease of more than 4 log units within 12 h in vitro. Phage vB8388 showed a strong synergistic effect with gentamicin that could enhance the anti-biofilm effect of vB8388. The phage + gentamicin combination also showed synergy in vivo in the larval infection model of Galleria mellonella. In conclusion, the findings of this study suggest the potential of phage + antibiotic combination therapy to be used as an alternative therapeutic approach for treating infectious diseases caused by multidrug-resistant bacteria.

[PMID: 34925270 PMCID: PMC8678519 DOI: 10.3389/fmicb.2021.763136] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Accepted: 11/04/2021] [Indexed: 12/13/2022] Open
Abstract
Klebsiella oxytoca is an important nosocomial and community-acquired opportunistic pathogenic Klebsiella and has become the second most prevalent strain in the clinic after K. pneumoniae. However, there have been few reports of bacteriophages used for treating K. oxytoca. In this study, a novel bacteriophage, vB_Kox_ZX8, which specifically infects K. oxytoca AD3, was isolated for the first time from human fecal samples. The biological characteristics of vB_Kox_ZX8 showed an incubation period of 10 min, a burst size of 74 PFU/cell, and a stable pH range of 3-11. Genomic bioinformatics studies of vB_Kox_ZX8 showed that it belongs to the genus Przondovirus, subfamily Studiervirinae, family Autographiviridae. The genome of vB_Kox_ZX8 is 39,398 bp in length and contains 46 putative open reading frames encoding functional proteins, such as DNA degradation, packaging, structural, lysin-holin, and hypothetical proteins. We further investigated the efficacy of vB_Kox_ZX8 phage in the treatment of mice with bacteremia caused by K. oxytoca infection. The results showed that vB_Kox_ZX8 (5 × 109 PFU/mouse) injected intraperitoneally alone was metabolized rapidly in BALB/c mice, and no significant side effects were observed in the control and treatment groups. Importantly, intraperitoneal injection with a single dose of phage vB_Kox_ZX8 (5 × 107 PFU/mouse) for 1 h post-infection saved 100% of BALB/c mice from bacteremia induced by intraperitoneal challenge with a minimum lethal dose of K. oxytoca AD3. However, all negative control mice injected with PBS alone died. Owing to its good safety, narrow host infectivity, high lysis efficiency in vitro, and good in vivo therapeutic effect, phage vB_Kox_ZX8 has the potential to be an excellent antibacterial agent for clinical K. oxytoca-caused infections.

Abstract
The prevalence of multidrug-resistant (MDR) strains has caused serious problems in the treatment of burn infections. MDR Enterobactercloacae and Enterobacterhormaechei have been defined as the causative agents of nosocomial infections in burn patients. In this situation, examination of phages side effects on human cell lines before any investigation on human or animal that can provide beneficial information about the safety of isolated phages. The aim of this study was to isolate and identify the specific bacteriophages on MDR E. cloacae and E. hormaechei isolated from burn wounds and to analyze the efficacy, cell viability and cell cytotoxicity of phages on A-375 and HFSF-PI cell lines by MTT (3-(4, 5-dimethylthiazol-2-yl)2,5-diphenyl-tetrazolium bromide) colorimetric assay and lactate dehydrogenase (LDH) release assay. Phages were isolated from urban sewage Isfahan, Iran. Enterobactercloacae strain Iau-EC100 (GenBank accession number: MZ314381) and E. hormaechei strain Iau-EHO100 (GenBank accession number: MZ348826) were sensitive to the isolated phages. Transmission electron microscopy (TEM) results revealed that PɸEn-CL and PɸEn-HO that were described had the morphologies of Myovirus and Inovirus, respectively. Overall, MTT and LDH assays showed moderate to excellent correlation in the evaluation of cytotoxicity of isolated phages. The results of MTT and LDH assays showed that, phages PɸEn-CL and PɸEn-HO had no significant toxicity effect on A375 and HFSF-PI 3 cells. Phage PɸEn-HO had a better efficacy on the two tested cell lines than other phage. Our results indicated that, there were significant differences between the two cytotoxicity assays in phage treatment compared to control.

Abstract
Mastitis (intramammary inflammation) caused by infectious pathogens is still considered a devastating condition of dairy animals affecting animal welfare as well as economically incurring huge losses to the dairy industry by means of decreased production performance and increased culling rates. Bovine mastitis is the inflammation of the mammary glands/udder of bovines, caused by bacterial pathogens, in most cases. Routine diagnosis is based on clinical and subclinical forms of the disease. This underlines the significance of early and rapid identification/detection of etiological agents at the farm level, for which several diagnostic techniques have been developed. Therapeutic regimens such as antibiotics, immunotherapy, bacteriocins, bacteriophages, antimicrobial peptides, probiotics, stem cell therapy, native secretory factors, nutritional, dry cow and lactation therapy, genetic selection, herbs, and nanoparticle technology-based therapy have been evaluated for their efficacy in the treatment of mastitis. Even though several strategies have been developed over the years for the purpose of managing both clinical and subclinical forms of mastitis, all of them lacked the efficacy to eliminate the associated etiological agent when used as a monotherapy. Further, research has to be directed towards the development of new therapeutic agents/techniques that can both replace conventional techniques and also solve the problem of emerging antibiotic resistance. The objective of the present review is to describe the etiological agents, pathogenesis, and diagnosis in brief along with an extensive discussion on the advances in the treatment and management of mastitis, which would help safeguard the health of dairy animals.

Abstract
Bovine mastitis caused by Klebsiella pneumoniae is usually treated with antibiotics, thereby potentially increasing antimicrobial resistance. The objective of this study was to evaluate efficacy of a bacteriophage, isolated from dairy farm wastewater, as a treatment for a murine model of K. pneumoniae mastitis. A lytic bacteriophage CM8-1 was isolated, morphological and biological characteristics were assessed with transmission electron microscopy and double-layer plate, and its genome was sequenced and analyzed. Furthermore, effectiveness of this bacteriophage for treatment of a murine model of K. pneumoniae mastitis was evaluated based on the following mammary gland characteristics: morphological changes; number of K. pneumoniae; and mRNA and protein expression of pro-inflammatory factors TNF-α, IL-1β, IL-6, and IL-8. Bacteriophage CM8-1 had an incubation period of 30 min and a burst time of 20 min. Its viability and adsorption were stable at 30 to 50°C, but decreased significantly at >60°C, with no significant change in viability or infectivity at pH 6 to 10. In a murine model of K. pneumoniae mastitis, injecting bacteriophage CM8-1 into the mammary gland 2 h after inoculation with K. pneumoniae resulted in reductions in bacterial counts in the murine mammary gland, improvements in mammary gland tissue morphology, and reductions in mRNA and protein expression of pro-inflammatory factors. Bacteriophage CM8-1 had stable biological characteristics and suppressed K. pneumoniae mastitis when injected into the mammary gland 2 h latera in mice bacterial inoculation.
