|September 1, 1978
Abstract:
Endogenous bacteriophage from clinically isolated, erythromycin-resistant strains of Streptococcus pyogenes, upon induction by treatment with mitomycin C, were demonstrated to cause transduction of antibiotic resistance yielding transductants resistant to relatively high concentrations of erythromycin. Transduction of resistance to erythromycin via endogenous phage may play a significant role in the emergence of streptococci with multiple resistance in the clinical environment.
Insights
Endogenous bacteriophage in Streptococcus pyogenes can transfer erythromycin resistance. This phage-mediated transduction may contribute to the rise of antibiotic-resistant bacteria in clinical settings.
Area of Science:
- Microbiology
- Molecular Biology
- Genetics
Background:
- Streptococcus pyogenes is a significant human pathogen.
- Antibiotic resistance in bacteria is a growing global health concern.
- The role of bacteriophage in horizontal gene transfer of antibiotic resistance is under investigation.
Purpose of the Study:
- To investigate the role of endogenous bacteriophage in transferring erythromycin resistance in Streptococcus pyogenes.
- To determine if bacteriophage can mediate the transduction of antibiotic resistance.
Main Methods:
- Isolation of endogenous bacteriophage from erythromycin-resistant Streptococcus pyogenes strains.
- Induction of bacteriophage release using mitomycin C treatment.
- Experimental transduction assays to transfer antibiotic resistance.
Main Results:
- Endogenous bacteriophage from Streptococcus pyogenes successfully transduced erythromycin resistance.
- Transductants exhibited resistance to high concentrations of erythromycin.
- Evidence suggests bacteriophage-mediated transfer of antibiotic resistance.
Conclusions:
- Endogenous bacteriophage of Streptococcus pyogenes are capable of transducing erythromycin resistance.
- Phage-mediated transduction may be a significant factor in the emergence of multidrug-resistant streptococci.
- Understanding these mechanisms is crucial for combating antibiotic resistance in clinical environments.

00:43Lysogenic Cycle of Bacteriophages
In contrast to the lytic cycle, phages infecting bacteria via the lysogenic cycle do not immediately kill their host cell. Instead, they combine their genome with the host genome, allowing the bacteria to replicate the phage DNA along with the bacterial genome. The incorporated copy of the phage genome is called the prophage. Some prophages can re-activate and enter the lytic cycle. This often occurs in response to a perturbation, such as DNA damage, but can also transpire in the absence of...
01:16Transduction
Among the three main modes of HGT—transformation, conjugation, and transduction—transduction is unique in that it is mediated by bacteriophages, or bacterial viruses.Transduction occurs in two ways. Generalized transduction occurs during the lytic cycle of a bacteriophage infection. In this process, bacteriophages infect bacterial cells, replicate within them, and ultimately cause cell lysis, releasing newly assembled virions. Occasionally, random fragments of the bacterial genome are...
01:30Development of Antibiotic Resistance
Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...
01:16Viral Replication: Lysogenic Cycle
The lysogenic cycle is a crucial viral replication strategy that allows bacteriophages to persist within host cells without immediately destroying them. This process is primarily observed in temperate phages, such as bacteriophage lambda (λ), which infects Escherichia coli. The cycle allows the viral genome to persist across bacterial generations while keeping host cells viable.Integration of the Viral GenomeUpon infection, bacteriophage lambda attaches to the bacterial surface and injects its...
01:27Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
01:25Mechanism of Antibiotic Resistance in MRSA
Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and acquisition...
