Insights

A patient developed peritonitis from Pasteurella multocida during peritoneal dialysis. Genetic analysis confirmed the infection originated from the patient

Area of Science:

  • Nephrology
  • Infectious Diseases
  • Zoonoses

Background:

  • Continuous cyclic peritoneal dialysis is a treatment for chronic kidney disease (CKD) in diabetic patients.
  • Peritonitis is a serious complication of peritoneal dialysis.

Observation:

  • A patient undergoing peritoneal dialysis for CKD secondary to type 2 diabetes mellitus developed peritonitis.
  • Pasteurella multocida was identified as the causative agent in the dialysis effluent.
  • The same bacterial strain was isolated from the patient's domestic cat.

Findings:

  • Pulsed-field gel electrophoresis (PFGE) demonstrated the P. multocida strains from the patient and the cat were identical.
  • This suggests a zoonotic transmission event from the pet cat to the patient.
  • The exact transmission route, despite no evidence of direct trauma to dialysis equipment, remains unknown.

Implications:

  • The increasing prevalence of pet ownership necessitates heightened awareness of potential zoonotic disease transmission.
  • Strict hygiene practices are crucial for pet owners, especially immunocompromised individuals, to prevent infections like zoonoses.
  • This case highlights the importance of considering animal contact in the differential diagnosis of peritonitis in patients on peritoneal dialysis.

Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
Plague01:24

Plague

Plague is a highly virulent zoonotic disease caused by Yersinia pestis, a Gram-negative, facultatively anaerobic coccobacillus. This pathogen primarily circulates among rodent populations and is transmitted to humans through the bite of infected fleas. Additional transmission routes include direct contact with infected animal tissue or inhalation of respiratory droplets from individuals with pneumonic plague. These multiple transmission pathways highlight the bacterium’s potential for rapid...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Inhalation Anthrax01:25

Inhalation Anthrax

Anthrax is a zoonotic disease caused by Bacillus anthracis, a Gram-positive, spore-forming bacterium. It primarily affects herbivorous animals but can be transmitted to humans through skin contact, ingestion, or inhalation of spores.Cutaneous anthrax, the most common form, typically results from direct contact with bacterial spores through skin abrasions and is generally less severe. Gastrointestinal anthrax results from eating undercooked or contaminated meat. It affects the mouth, throat, or...
Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
