Klebsiella pneumoniae como patógeno intrahospitalario: epidemiología y resistencia

Abstract

La resistencia bacteriana es un problema serio, de magnitud creciente y presentación universal, que reviste gran importancia, especialmente en los ambientes hospitalarios; los microorganismos más frecuentemente aislados de pacientes con infecciones intrahospitalarias son Staphylococcus aureus y Escherichia coli. En Medellín, sin embargo, Klebsiella pneumoniae ha cobrado gran importancia en años recientes debido a su gran incremento como agente causal de ese tipo de infecciones, lo que motiva esta revisión. Se incluyen los siguientes aspectos: microbiología, epidemiología, diseminación, resistencia a los beta-lactámicos y sus mecanismos, impacto clínico e importancia del problema en la ciudad.

Antibacterial potential of leaf and fruit of citrus extract (Citrus aurantifolia) against klebsiella oxytoca

“…Klebsiella is a type of bacteria that is gram-negative, anaerobic, and rod-shaped. It is commonly found in the intestinal tract and is known to be an opportunistic pathogen, meaning it can cause infections in people with weakened immune systems (Echeverri & Catano, 2010). 10.31932/jpbio.v8i1.2261…”

Bloodstream infections and its antibiogram from a tertiary care hospital of western India

“…1,3 The most common bacteria genera responsible for BSIs are Klebsiella, Escherichia, and Staphylococcus. 3,4 BSIs can originate from various sources, including infections in other parts of the body such as the lungs, urinary tract, or surgical wounds. 1,4,5 They can also occur as a result of medical procedures such as intravenous catheter insertion or from the spread of an existing infection.…”

“…3,4 BSIs can originate from various sources, including infections in other parts of the body such as the lungs, urinary tract, or surgical wounds. 1,4,5 They can also occur as a result of medical procedures such as intravenous catheter insertion or from the spread of an existing infection. 6 Symptoms of a bloodstream infection can vary depending on the severity and the underlying cause but often include fever, chills, low blood pressure, and general malaise.…”

“…In severe cases, sepsis can develop, which is a life-threatening condition characterized by widespread inflammation throughout the body. 1,4 Diagnosis of BSIs involves blood cultures, where a sample of blood is collected and cultured to identify the presence of microorganisms. [7][8][9] Treatment typically involves the administration of appropriate antibiotics or antifungal agents, depending on the causative organism.…”

Evaluación in vitro del efecto bactericida del Piper aduncum "matico" frente a Klebsiella pneumoniae ATCC BAA1706 y Staphylococcus aureus ATCC 25923

“…Por otra parte, el Piper aduncum no presentó efecto bactericida frente a Klebsiella pneumoniae, que es una bacteria gram negativa, debido quizás a su cápsula hidrófila que la protege de los fagocitos y de los factores bactericidas del huésped (34). En cambio, a diferencia del Staphylococcus aureus que es un gram positivo que no posee cápsula, podría explicar que haya un efecto bactericida.…”
