👉 The Meyer-Infection theory, proposed by Dr. John Meyer in the early 20th century, describes a model of bacterial infection where the initial interaction between bacteria and host cells is crucial for the disease process. According to this theory, bacteria first adhere to host cells via specific receptors on the cell surface, a step that can be influenced by environmental factors such as pH and nutrient availability. Once adhered, bacteria may invade host cells or remain extracellular, leading to inflammation and tissue damage. The theory emphasizes the importance of bacterial virulence factors, which facilitate this initial attachment and subsequent infection, setting the stage for the complex immune response that follows. This model highlights the dynamic interplay between pathogens and the host's defense mechanisms, underscoring the critical role of early bacterial-host interactions in the onset and progression of infection.
