Bacterial resistance to multiple drugs is considered one of the major global health threats facing modern societies. At the heart of this phenomenon, carbapenem-resistant Klebsiella pneumoniae (CR-Kp) stands out as one of the most dangerous health threats due to its extensive resistance and lethal impact in the hospital environment. Therefore, medical research is seeking effective alternatives to traditional antibiotics, with bacteriophages representing one of the potential solutions. This new study reviews the isolation of four phages to treat Klebsiella pneumoniae strains with genotypes ST307 and ST147, outlining their characteristics and efficacy factors. Through these results, scientists aim to provide new therapeutic prospects in combating this increasing health dilemma, opening the door for a better understanding of the use of phages as a sustainable treatment against resistant bacterial diseases.
Spread of Antibiotic-Resistant Bacteria and Its Challenges
The spread of bacteria resistant to a potent class of antibiotics, known as MDR, represents a significant public health threat worldwide. These bacteria, often attributed to the ineffectiveness of conventional drugs, lead to increased mortality rates and prolonged hospital stays. For instance, infections caused by these types of bacteria were responsible for over 1.27 million deaths in 2019. As the spread of these germs continues, the need for new antibiotics grows, a challenge that requires a globally coordinated response from all countries.
Carbapenem-resistant Klebsiella pneumoniae, or CR-Kp, is one of the highly resistant pathogens that raises concern on both medical and global levels. These germs are considered major adversaries in hospitals, leading to localized and regional outbreaks. These strains are viewed particularly critically due to their high resistance rates, with resistance levels exceeding 20% in some countries. Thus, the development of new antibiotics has become not only an urgent necessity but also essential for developing alternative therapeutic strategies that revive hope in controlling these infections.
Alternative Treatment Strategies: Bacteriophage Therapy
The scarcity of effective therapeutic options has led to the rediscovery of bacteriophages as a promising strategy to combat antibiotic-resistant bacteria. This strategy was utilized in the early 20th century and involves using viruses that attack and kill bacteria. Bacteriophages are part of the microbiome ecosystem and can be isolated from natural sources such as wastewater. Bacteriophage therapy possesses unique characteristics that make it adaptable to many bacterial strains, making it the optimal solution for dealing with CR-Kp strains.
Moreover, the use of bacteriophages is less likely to cause severe side effects compared to traditional antibiotics. Studies have shown that these viruses do not contain antibiotic resistance genes or virulence factors, meaning they target only pathogenic germs without affecting beneficial bacteria in the gut. This precision of action makes bacteriophages ideal candidates for therapy, especially in the current health conditions dominated by microbial resistance.
Isolation and Characterization of Targeted Bacteriophages for K. pneumoniae
In a recent study, four phage strains targeting CR-Kp Klebsiella pneumoniae strains were isolated. These strains were obtained from wastewater samples and are characterized by their specific resistance patterns to bacteria. These strains were able to destroy K. pneumoniae strains belonging to two specific types, ST307 and ST147. The results of the experiments show that 85.7% of ST307 strains were susceptible to the bacteriophage, indicating a high relative capacity to eliminate these bacterial patterns.
Each isolated bacteriophage strain was subjected to detailed analysis regarding stability over a wide range of pH and temperature. It was also observed that these viruses enjoy latent periods ranging from 10 to 50 minutes, producing between 10 to 100 plaque-forming units. The genetic characterization study of these viruses also reveals the absence of antibiotic resistance genes or virulence factors, supporting the idea of their use as an effective and biologically safe treatment.
Opportunities

One common method for assessing phage host range is the spot test, where a set of K. pneumoniae strains is used to determine the sensitivity of the strains to isolated bacteriophages. This process involves culturing bacterial cells on a nutrient medium and then applying the phages to identify the presence of lysis zones. Strains are classified based on their response – whether they are sensitive, partially sensitive, or resistant – providing an overview of how phages interact with various bacterial strains.
Evaluation of Phage Culture Efficiency
Phage culture efficiency, also known as the efficiency of bacteriophage in causing productive infections in sensitive or partially sensitive incidental strains, represents vital aspects in phage research. This efficiency is measured using a double-layer plating technique, where different dilutions of phages are applied to specific bacterial strains. The results of these tests provide valuable information regarding the efficiency of phages in achieving infection and whether they can form plaque-forming units in culture.
Efficiency results are plotted based on the number of active units in each group. Phages are classified according to their efficiency: high-producing (EOP ≥ 0.5), medium-producing (0.1 ≤ EOP < 0.5), low-producing, and non-effective. This information sheds light on how phages can be used as a potential treatment against antibiotic-resistant bacteria and their contribution to developing new tools for combating infections.
Single Growth Curve and Temporal Gaps
Analyzing the single growth curve contributes to understanding how quickly phages replicate and the duration of the latent periods they require before new viruses begin to proliferate. The burst size, which is the number of phages produced from each infected bacterial cell, is calculated to help evaluate phage efficacy. This analysis is crucial for determining the therapeutic potential of phages.
To assess the potential use of phages as treatments, temporal events related to phage replication are monitored. The single curve involves sampling from bacterial cultures at specified time intervals to measure phage activity. This helps highlight how quickly phages spread and how this can be influenced by various environmental factors.

Reports from the World Health Organization indicate that bacterial resistance is unfortunate as it leads to increased mortality, economic burdens, and longer hospital stays.
This challenge has been exacerbated by the fact that resistant bacteria are not limited to hospitals but have also become present in the community, making it difficult to identify sources of infection. Diseases that include muscle infections, pneumonia, and urinary tract infections have become more common due to the emergence of resistant strains such as “ST307” and “ST147” of “Klebsiella pneumoniae.” Therefore, urgent action is required to reduce inappropriate antibiotic use and develop effective treatment and prevention strategies.
The Importance of Research and Development in Combating Antibiotic Resistance
Researchers face immense challenges in developing new drugs to combat resistant bacteria. The list of microorganisms posing significant threats is increasing, making it essential to invest more resources into research and development. For example, strains of “Klebsiella pneumoniae” are among the most significant problems in infection control, as they are commonly found in hospitals and acquire resistance to antibiotics.
Recent research includes new strategies such as developing drugs that target resistance mechanisms or using gene therapy to control the spread of resistant bacteria. Additionally, the medical community must promote awareness of the importance of responsible antibiotic use and support initiatives aimed at developing new tools such as phage therapy, which shows promising potential in treating resistant bacterial infections.
Global Collaboration to Address Antimicrobial Resistance
Addressing the phenomenon of antimicrobial resistance requires integrated efforts on a global scale. It necessitates cooperation between countries and improved communication between public health entities and scientific research. Comprehensive strategies must be established that range from public awareness, regulating the use of antimicrobials, to creating incentives for industries to develop new drugs. Among the notable global initiatives is one led by the World Health Organization, which has established a priority list of resistant bacteria representing health threats, helping to guide research and innovation.
For instance, countries can work on developing networks to monitor antimicrobial resistance and share data related to infections. Furthermore, research into new methods and techniques to combat resistance should be enhanced, contributing to improved treatment and prevention strategies. Collaborative efforts are a critical factor in curbing this global phenomenon; thus, efforts towards building effective partnerships between governments, researchers, and health industries should be pursued.
