Heat is the most commonly used method to fully destroy bacteria, including any proteins they leave behind. The second method is filtering. If you're trying to make sure that a liquid, such as.. How does a macrophage kill bacteria? When a macrophage ingests a pathogen, the pathogen becomes trapped in a phagosome, which then fuses with a lysosome. Within the phagolysosome, enzymes and toxic peroxides digest the pathogen. However, some bacteria, such as Mycobacterium tuberculosis, have become resistant to these methods of digestion There are many herbs and plant foods that kill bacteria in the gut. The problem is that they kill 'good' bacteria too. We can't say it enough: a happy microbiome is a diverse microbiome.
