“Neisseria gonorrhoeae” is considered one of the most significant global health challenges, as it is the primary cause of gonorrhea, which is one of the most widely spread infectious diseases in the world. Over time, this bacteria has been able to develop resistance against all recommended antimicrobial treatments, and recent concerns have centered around new genetic alleles such as “penA-60” and “penA-237” that are associated with high resistance to antibiotics such as “Ceftriaxone.” In this article, we review the emergence and spread of these alleles, highlight how resistance against antimicrobials has developed, and discuss the impact of this on public health in the future. We will also discuss the importance of continuous monitoring of strain development and understanding their sources to combat this growing problem.
Emergence of Antimicrobial Resistance in Neisseria gonorrhoeae
Neisseria gonorrhoeae is one of the bacteria responsible for gonorrhea infections, and it is an sexually transmitted infectious disease that presents a global health threat. This bacteria has undergone significant evolution in its antibiotic resistance, making it increasingly difficult to combat this infection. In recent years, strains of Neisseria gonorrhoeae with high levels of resistance to the antibiotic ceftriaxone, which was the last single recommended treatment for this infection, have been discovered.
In 2019, the FC428 strain was identified, which carries the mosaic penA-60 resistance gene, associated with high minimum inhibitory concentrations (MICs) of ceftriaxone. This strain was first discovered in Las Vegas, USA, and since then has spread globally. This phenomenon represents a worrying sign of the increasing ability of Neisseria gonorrhoeae to develop effective resistance even to the latest available treatments, raising the need for proper monitoring and understanding of the evolutionary dynamics of these organisms.
The resistance of Neisseria gonorrhoeae requires immediate responses from medical examination and scientific research to ensure the availability of effective treatment options in the future. The presence of factors such as the mosaic penA-60 strain poses a threat to individuals and communities, indicating that Neisseria gonorrhoeae can adapt and evolve under the pressure of frequent antibiotic use. In light of this fact, continuous monitoring and international cooperation are essential to control the spread of these alarming strains.
Genetic Analysis of Resistant Strains
A large-scale study was conducted to analyze the genome and evolutionary relationships among three isolates carrying the mosaic penA-60 gene. This study included 2104 genomes of the MLST-1901 lineage, focusing on understanding the complex evolutionary dynamics that lead to the emergence of these strains in different areas. Specifically, three prominent isolates were observed: GCWGS-10723, F92, and H22-722, which recorded high levels of ceftriaxone resistance and were grouped within one lineage in the first genetic cluster.
Additionally, two bacterial species, Neisseria sicca and Neisseria mucosa, were identified as potential sources for the independent recombination events that led to the emergence of the new resistant genes. These findings suggest multiple evolutionary pathways that could lead to the emergence of new resistance genes through lateral recombination between traditional Neisseria gonorrhoeae strains and beneficial bacterial species. These complex dynamics highlight that the surrounding environment may play an important role in enhancing the spread of resistance.
Future research should continue to focus on tracking and identifying resistant strains in areas that have seen increases in infections, especially in remote areas such as Asia. Clear phases in monitoring and investigating new strains are required to understand the rise of antimicrobial resistance in response to this global challenge.
The Importance of Surveillance and Prevention Strategies
Effective surveillance of epidemics is a key aspect of containing Neisseria gonorrhoeae resistance. The ongoing rise in antimicrobial resistance cases calls for robust and sustainable monitoring mechanisms for populations and communities. Countries need to enhance infectious disease control programs that include developing effective vaccination and early treatment strategies. This includes improving access to healthcare, promoting education and awareness about the risks associated with sexually transmitted infections and how to prevent their transmission.
Furthermore,
Regular examinations by medical authorities represent a significant milestone in the early detection of resistant strains. Thanks to advanced genetic technologies, strains of Neisseria gonorrhoeae can be classified and understood more accurately, aiding the innovative development of treatment strategies. The scientific and medical community must strive to develop a coordinated and integrated response that includes partnerships between countries and healthcare facilities to enhance the capacity of research to address these global health challenges.
Prevention is an integral part of combating drug resistance, and thus, the focus should be on promoting good health practices among individuals and communities. Educating individuals about the importance of using condoms, reducing the number of sexual partners, and regular monitoring of sexual health can all contribute to reducing the spread of infections. Creating a healthy environment that minimizes the likelihood of resistant strains spreading is a shared dream that everyone should strive to achieve.
Future Challenges in Combating Neisseria gonorrhoeae Resistance
Combating Neisseria gonorrhoeae resistance faces several challenges, including the increasing levels of resistance against available drugs, as well as many healthcare systems’ inability to cope with the new situation.

CutAdapt is also employed to remove unwanted sequences, allowing for accurate analysis of the strain’s genome. The isolated strains are also analyzed using programs like Spades to create genetic assemblages that include vital information about the strain, such as occurring mutations and growth conditions.
The genetic patterns of antibiotic resistance determinants are identified using specialized tools such as ARIBA and Neisseria gonorrhoeae Genome Profiler, which facilitate distinguishing resistant strains from sensitive ones. The analysis of complete genetic data requires the integration of genetic knowledge with clinical data to provide a clearer picture of how resistant strains evolve and understand how to combat them in the future.
Analysis of Genetic Factors and Evolutionary Development
Analyzing the genetic factors of strains is a fundamental step in understanding how antibiotic resistance develops. Using evolutionary analysis axes, the relationship between different strains and the impact of genetic factors on their resistance is understood. A phylogenetic tree is created using highly precise analyses like RAxML to reflect the relationships between strains and their spread.
The results show that gonorrhea strains are closely related to each other, indicating that the evolution of antibiotic resistance may be linked to genetic changes that occurred in common ancestors. Both SNP analysis and repeat frequency analysis are important tools for tracing lineages and resistance factors, allowing researchers to understand how new strains can evolve under certain conditions.
Based on the obtained results, it can be concluded that the specific genes of the strains are not static, but continuously evolve in response to environmental pressures and human usage factors. Therefore, it is important to establish data-driven evolutionary programs to track resistant strains and identify how genetic separations occur.
Future Research and Diagnostic Prospects
As research continues in the fields of genetic sequencing and phylogenetic analysis, new prospects emerge for diagnosing pathogenic strains and improving treatment strategies.

The Evolutionary Tree and Isolation of the First Line
The topic of the evolutionary tree relates to understanding the genetic relationship between different bacterial strains, which is revealed through genetic sequencing analysis. In this case, the evolutionary tree concerns Neisseria gonorrhoeae strains, where a small group named MLST-1901 has been identified. This group includes 19 samples tracing the first line and contains three main strains with high resistance to ESC drugs, namely GCWGS-10723, H22-722, and F92. These strains are characterized by high genetic diversity, representing samples from North America and Southeast Asia. This tree indicates the genetic root relationships and how these strains have evolved in different environments.
It is important to…
genetic factors such as genetic sequence changes like SNPs (single nucleotide polymorphisms) are key indicators of genetic identity. For example, the GCWGS-10723 strain from Las Vegas, USA exhibited significant variation, indicating it is a highly diverse strain within the first line. The closest genetic strain was found in Canada, specifically strain 88259, suggesting there are shared genetic determinants between the two strains. However, strain GCWGS-10723 has been exposed to different genetic reservoirs, indicating potential Asian origins.
Genetic Analysis and Genetic Diversity
Genetic analysis is a powerful tool for understanding genetic diversity among strains. In this case, advanced methods such as allele analysis and investigation of changes in the penA gene, which plays a pivotal role in antibiotic resistance, were used. Strains like H22-722 and F92, which harbor genetically adjacent strains, showed significant genetic differences with strain GCWGS-10723. The DNA segment studied in these strains is among the most important areas for studying genetic diversity, as it contains genetic variations that affect drug resistance.
Research shows that a significant amount of genetic shifts has occurred in resistance-related genes, meaning that strains can quickly adapt to new environments or under drug pressure. For example, strains have been found carrying mutations at the gene level indicating specific resistance to certain agents like drugs. Analysis shows that almost all strains in the first line, except one, contain mutations related to ciprofloxacin resistance, demonstrating how genetic adaptation processes can affect the efficacy of treatment in clinical cases.
Strain Distribution and Antibiotic Resistance
The distribution of strains and resistance to antibiotics is a critical topic in the study of bacterial strains. The first line has representatives from many geographic regions, with North America and Southeast Asia being major areas. This may mean that drug resistance processes have evolved separately in different environments, complicating the fight against these strains. Both strains GCWGS-10723 and H22-722 possess genetic mutations leading to specific resistance to antimicrobial drugs like azithromycin. It also appears that there are distinct genetic changes leading to increased strain resistance.
Factors influencing the development of resistance include the environment and specific strain genetics. Environmental factors such as the use of antibiotics in veterinary medicine or extensively in public health care may cause strain resistance to develop. Analyses show that strains carry certain genetic groups, such as penA alleles, that directly affect antibiotic resistance. These genetic strains are distributed across regions. In the United States, for instance, specific genetic mutations correlated to a range of strains have been observed, suggesting the presence of a progenitor strain that may be the source of this resistance.
Recombination Events and Genetic Changes
Recombination events are a key factor in genetic diversity. By analyzing the penA gene and associated regions, several recombination events have been identified that occurred among different strains. By utilizing advanced analytical tools such as Gubbins, multiple recombination events were identified within the MLST-1901 group. These events may lead to the transfer of resistance-related genes among strains, increasing their ability to adapt to new factors.
Recombination events reflect the important role of genetic interactions among different species. Some strains have transferred specific genes, leading to the formation of new strains with distinct genetic traits. It is noteworthy that these events can lead to the emergence of new strains that may be more resistant or confer competitive advantages in their surrounding environment. Therefore, studying these events is a crucial element in understanding how strains evolve and their ability to survive medical treatment.
