Lysogenic Cycle of Bacteriophages

Lysogenic 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...

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...

Gastritis-II: Pathophysiology

Gastritis-II: Pathophysiology

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Summary

Arcobacter butzleri poses a public health threat due to emerging antibiotic resistance. Most tested antibiotics showed resistance, except erythromycin, necessitating further study for effective treatment and control.

Area of Science:

Foodborne pathogens
Microbiology
Public health

Background:

Arcobacter butzleri is an emerging foodborne pathogen causing bacterial enteritis.
Vulnerable populations are more susceptible to A. butzleri infections.
Antibiotic resistance in A. butzleri complicates empirical treatment and poses a public health risk.

Purpose of the Study:

To assess the antibiotic resistance profile of Arcobacter butzleri isolates.
To identify effective antimicrobial agents for treating A. butzleri infections.

Main Methods:

Seven isolates of Arcobacter butzleri were collected in 2024.
Antimicrobial susceptibility testing was performed using first-line antibiotics for gastroenteritis.

Main Results:

Resistance rates exceeding 25% were observed for all tested antimicrobials, with the exception of erythromycin.
Erythromycin demonstrated susceptibility against the tested A. butzleri isolates.

Conclusions:

Arcobacter butzleri exhibits significant resistance to common antibiotics.
Erythromycin may be a potential treatment option, but further investigation into the antimicrobial resistance profile is crucial for effective control strategies.
