Abstract
SUMMARYDespite the early recognition of their therapeutic potential and the current escalation of multidrug-resistant (MDR) pathogens, the adoption of bacteriophages into mainstream clinical practice is hindered by unfamiliarity with their basic pharmacokinetic (PK) and pharmacodynamic (PD) properties, among others. Given the self-replicative nature of bacteriophages in the presence of host bacteria, the adsorption rate, and the clearance by the host's immunity, their PK/PD characteristics cannot be estimated by conventional approaches, and thus, the introduction of new considerations is required. Furthermore, the multitude of different bacteriophage types, preparations, and treatment schedules impedes drawing general conclusions on their in vivo PK/PD features. Additionally, the drawback of acquired bacteriophage resistance of MDR pathogens with clinical and environmental implications should be taken into consideration. Here, we provide an overview of the current state of the field of PK and PD of bacteriophage therapy with a focus on its application against MDR Gram-negative infections, highlighting the potential knowledge gaps and the challenges in translation from the bench to the bedside. After reviewing the in vitro PKs and PDs of bacteriophages against the four major MDR Gram-negative pathogens, Klebsiella pneumoniae, Acinetobacter baumannii complex, Pseudomonas aeruginosa, and Escherichia coli, specific data on in vivo PKs (tissue distribution, route of administration, and basic PK parameters in animals and humans) and PDs (survival and reduction of bacterial burden in relation to the route of administration, timing of therapy, dosing regimens, and resistance) are summarized. Currently available data merit close scrutiny, and optimization of bacteriophage therapy in the context of a better understanding of the underlying PK/PD principles is urgent to improve its therapeutic effect and to minimize the occurrence of bacteriophage resistance.

Abstract
Poultry production faces challenges from bacterial infections, aggravated by antibiotic resistance, affecting bird welfare and the industry's economy. Bacteriophages show promise as a solution, but their use in poultry systems is still limited. This study uses scientometric analysis to investigate the incidence of bacterial infections in poultry systems and bacteriophage application trends. The Web of Science database was used, and the articles were refined by searching for keywords that included the most rep orted bacteria in the different phases of poultry farming and the application of phages. The articles were analyzed using the CiteSpace and Excel software, allowing the evaluation of publication trends, influential countries, and correlations with antimicrobial resistance and the use of bacteriophages. Results highlight Escherichia coli prevalence in poultry systems and reveal a correlation between the number of publications and poultry productivity, with the United States and China leading both aspects. Findings offer insights into bacterial control gaps in poultry systems, underscoring the need for further research and practical strategies.

Abstract
Importance Evaluation of the microbiological diagnostic profile of multidrug-resistant Pseudomonas aeruginosa keratitis and potential management with rose bengal-photodynamic antimicrobial therapy (RB-PDAT) is important. Objective To document the disease progression of carbapenemase-resistant P aeruginosa keratitis after an artificial tear contamination outbreak. Design, Setting, and Participants This retrospective observation case series included 9 patients 40 years or older who presented at Bascom Palmer Eye Institute and had positive test results for multidrug-resistant P aeruginosa keratitis between January 1, 2022, and October 31, 2023. Main Outcomes and Measures Evaluation of type III secretion phenotype, carbapenemase-resistance genes blaGES and blaVIM susceptibility to antibiotics, and in vitro and in vivo outcomes of RB-PDAT against multidrug-resistant P aeruginosa keratitis. Results Among the 9 patients included in the analysis (5 women and 4 men; mean [SD] age, 73.4 [14.0] years), all samples tested positive for exoU and carbapenemase-resistant blaVIM and blaGES genes. Additionally, isolates were resistant to carbapenems as indicated by minimum inhibitory concentration testing. In vitro efficacy of RB-PDAT indicated its potential application for treating recalcitrant cases. These cases highlight the rapid progression and challenging management of multidrug-resistant P aeruginosa. Two patients were treated with RB-PDAT as an adjuvant to antibiotic therapy and had improved visual outcomes. Conclusions and Relevance This case series highlights the concerning progression in resistance and virulence of P aeruginosa and emphasizes the need to explore alternative therapies like RB-PDAT that have broad coverage and no known antibiotic resistance. The findings support further investigation into the potential effects of RB-PDAT for other multidrug-resistant microbes.

Abstract
Escherichia coli is a commensal bacterial species in the human gastrointestinal tract; however, it could be pathogenic and cause severe infections in intra and extra-intestinal sites. Uropathogenic E. coli accounts for 80-90% of urinary tract infections that can result in urosepsis and septic shock. Consequently, multidrug-resistant uropathogenic E. coli poses a considerable risk to the healthcare system worldwide. Phage therapy is demonstrated as an optimistic solution to over-the-counter antibiotics that contribute to the global issue of multidrug-resistant bacteria. This study aims to isolate a novel phage that could be implemented to cure urinary tract infections mediated by multidrug-resistant E. coli. Twenty-seven E. coli isolates were collected from patients with urinary tract infections to assess the antibacterial efficacy of phage vB_Ec_ZCEC14. Phage kinetics were encountered against the E. coli strain (EC/4), in addition to evaluating phage stability under various temperatures, pH values, and UV exposure periods. Full genome sequencing and morphological analysis were conducted for further phage characterization, which revealed that phage vB_Ec_ZCEC14 belongs to the family Straboviridae. Phage vB_Ec_ZCEC14 showed thermal tolerance at 80 ℃, pH stability between pH 3 and pH 12, and endurance to UV exposure for 45 min. The phage-host interaction results revealed that phage vB_Ec_ZCEC14 has strong and steady antibacterial action at lower concentrations (MOI 0.1). The study findings strongly indicate that phage vB_Ec_ZCEC14 holds significant promise as a potential therapeutic alternative for treatment of antibiotic-resistant uropathogenic E. coli.

Abstract
Pseudomonas aeruginosa is considered as one of the human health care problems, P. aeruginosa's carbapenem resistance emerges by several different mechanisms, some of which include carbapenems genes. P. aeruginosa's carbapenem resistance is a significant health concern, So this study aims to evaluate MBL gene expressions. The study was conducted at the Department of Microbiology, AL-Mahmoodia Hospital, over one year from January to December 2022. The samples were collected from patients with different clinical sources (Burn, Urine, Wound, Sputum, Ear, and Blood), from different ages while. Samples were collected from three hospitals in Baghdad including Al-Yarmouk Teaching Hospital, AL-Mahmmodiya Hospital, and Child's Central Teaching Hospital. A study analyzed 55 P. aeruginosa strains from various clinical sources, the study utilizes the chemical characterization, VITEK 2 system, 16s rRNA, antibiogram sensitivity tests, antibiotic susceptibility using eight antibiotics, including Amikacin, Ciprofloxacin, Levofloxacin, Imipenem Meropenem, Piperacillin, Cefepim and Aztreonam. The test of bacterial susceptibility revealed that each isolate was highly resistant to piperacillin, which are 96.36%, and lower resistance to Ciprofloxacin, which are 32%. Phenotypic screening carbapenem resistance methods combined the disk synergy test and conventional PCR that were used to detect isolates by using 16 S rRNA. This proves that the bacteria is P. aeruginosa and computed by measuring gene expression of the target genes (GIM, VIM, SPM) by using the real-time PCR, which is employed for twenty-five isolates. The result indicates that the expression level of the VIM gene is highly regulated in carbapenem-resistance isolates compared to control isolates that is 1.00. While the expression level of gene GIM and SPM is downregulated in carbapenem-resistance isolates compared to control isolates that is 6. The carbapenem VIM and GIM, SPM (class B) genes are essential for resistance in P. aeruginosa induced by chromosomal changes that modify membrane permeability efflux pump overexpression for genes. As a result, many studies require for discovering new strategies to reduce the threat to public health through preventing the spread of these isolates via tight infections, control measures, and the reduction of the danger to public health.

Abstract
Abstract
Background
Antibiotic-resistant Pseudomonas aeruginosa (P. aeruginosa) is one of the most critical pathogens in wound infections, causing high mortality and morbidity in severe cases. However, bacteriophage therapy is a potential alternative to antibiotics against P. aeruginosa. Therefore, this study aimed to isolate a novel phage targeting P. aeruginosa and examine its efficacy in vitro and in vivo.
Results
The morphometric and genomic analyses revealed that ZCPA1 belongs to the Siphoviridae family and could infect 58% of the tested antibiotic-resistant P. aeruginosa clinical isolates. The phage ZCPA1 exhibited thermal stability at 37 °C, and then, it decreased gradually at 50 °C and 60 °C. At the same time, it dropped significantly at 70 °C, and the phage was undetectable at 80 °C. Moreover, the phage ZCPA1 exhibited no significant titer reduction at a wide range of pH values (4–10) with maximum activity at pH 7. In addition, it was stable for 45 min under UV light with one log reduction after 1 h. Also, it displayed significant lytic activity and biofilm elimination against P. aeruginosa by inhibiting bacterial growth in vitro in a dose-dependent pattern with a complete reduction of the bacterial growth at a multiplicity of infection (MOI) of 100. In addition, P. aeruginosa-infected wounds treated with phages displayed 100% wound closure with a high quality of regenerated skin compared to the untreated and gentamicin-treated groups due to the complete elimination of bacterial infection.
Conclusion
The phage ZCPA1 exhibited high lytic activity against MDR P. aeruginosa planktonic and biofilms. In addition, phage ZCPA1 showed complete wound healing in the rat model. Hence, this research demonstrates the potential of phage therapy as a promising alternative in treating MDR P. aeruginosa.
