Abstract

Insights

Elderly patients experiencing persistent diarrhea after antibiotic treatment may have Clostridioides difficile infection. Prompt diagnosis and targeted therapy, such as with ciprofloxacin, are crucial for recovery.

Area of Science:

  • Gastroenterology
  • Infectious Diseases
  • Geriatrics

Background:

  • Antibiotic therapy can disrupt the gut microbiome, leading to opportunistic infections.
  • Elderly patients are particularly vulnerable to complications from dysbacteriosis.

Observation:

  • A case of an elderly patient presenting with persistent diarrhea following antibiotic treatment for a respiratory infection.
  • Colonoscopy revealed proctosigmoiditis with membranous exudations.
  • Stool culture confirmed an antibiotic-associated infection caused by Pseudomonas aeruginosa.

Findings:

  • Pseudomonas aeruginosa identified as the causative agent of antibiotic-associated diarrhea.
  • Oral ciprofloxacin therapy demonstrated effectiveness in treating the infection.

Implications:

  • Highlights the risk of antibiotic-associated infections in the elderly.
  • Emphasizes the importance of considering dysbacteriosis and secondary infections in elderly patients with persistent diarrhea post-antibiotics.
  • Ciprofloxacin can be an effective treatment option for Pseudomonas aeruginosa-induced enteritis.

Development 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...

Infection01:20

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Stages of Infection01:26

Stages of Infection

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Sexually Transmitted Infections01:26

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
