Streptococcus pneumoniae es resistente a la penicilina y al cloramfenicol
Lancet (London, England)
|November 12, 1977
Resumen
Los neumococos resistentes a la penicilina, las cefalosporinas y el cloramfenicol causaron infecciones graves. A pesar del tratamiento, los casos de meningitis fueron fatales, mientras que los casos de sepsis se recuperaron, destacando los desafíos en la resistencia a los antibióticos.
Área de la Ciencia:
- Microbiología Microbiología.
- Enfermedades infecciosas Enfermedades infecciosas.
- La medicina clínica es la medicina clínica.
Sus antecedentes:
- La emergente resistencia a los antibióticos en Streptococcus pneumoniae plantea una amenaza significativa para la salud pública.
- Las penicilinas, las cefalosporinas y el cloramfenicol son antibióticos críticos para el tratamiento de las infecciones neumocócicas.
Objetivo del estudio:
- Para informar casos clínicos de enfermedad neumocócica invasiva causada por cepas resistentes a múltiples antibióticos.
- Para investigar las características de estos neumococos resistentes.
Principales métodos:
- Reporte y revisión de casos clínicos.
- Análisis microbiológico de los aislados de neumococos causantes, incluida la prueba de beta-lactamasa.
Principales resultados:
- Se identificaron cinco casos de enfermedad neumocócica invasiva (3 meningitis, 2 septicemia).
- Los aislamientos de neumococos mostraron resistencia a las penicilinas, las cefalosporinas y el cloramfenicol.
- No se detectó actividad de la beta-lactamasa en las cepas resistentes.
- Todos los pacientes con meningitis sucumbieron a la infección.
- Los pacientes con septicemia sobrevivieron después de un tratamiento adecuado con antibióticos.
Conclusiones:
- Los neumococos resistentes a los antibióticos clave pueden causar meningitis y septicemia que amenazan la vida.
- La falta de beta-lactamasa en estas cepas resistentes sugiere mecanismos de resistencia alternativos.
- La terapia antibiótica efectiva es crucial para la supervivencia en los casos de septicemia neumocócica, incluso con cepas resistentes.

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...
01:14Atypical 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...
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...
01:23Inhibitors of Gram-positive Cell Wall Synthesis
Bacterial cell walls are typically rigid structures composed mainly of peptidoglycan, a mesh-like polymer that provides mechanical strength and maintains cell shape. The synthesis of peptidoglycan is a crucial process in bacterial growth and serves as a primary target for many antibiotics.Mechanism of Action of Beta-Lactam AntibioticsBeta-lactam antibiotics, such as penicillin, inhibit peptidoglycan synthesis in actively growing cells. These antibiotics share a characteristic four-membered...
01:25Clinical 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...
01:29Pneumonia I: Introduction
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
