Many plant pathogens produce virulence factors, or effectors, that modulate or interfere with normal host processes to the benefit of the pathogens. The first phytoplasmal virulence factor, a secreted protein termed “tengu-su inducer” (TENGU; C0H5W6 ), was identified in 2009 from a phytoplasma causing yellowing of onions .
Phyllody on a purple coneflower (Echinacea purpurea). Phyllody is the abnormal development of floral parts into leafy structures. It is generally caused by phytoplasma or virus infections, [1] though it may also be because of environmental factors that result in an imbalance in plant hormones. [2]
Exotoxins are typically proteins with enzymatic activity that interfere with host cells triggering the symptoms associated with the disease. Exotoxins are also relatively specific to the bacteria that produce it; for example, diphtheria toxin is only produced by Corynebacterium diphtheriae bacteria and is required for the diphtheria disease.

Some herbal supplements—like turmeric, cinnamon, St. John’s Wort and echinacea—can interfere with how your body processes prescription and over-the-counter medications, leading to potential ...
Echinacea has also been linked to allergic reactions, including asthma, shortness of breath, and one case of anaphylaxis. [35] [36] [37] Muscle and joint pain has been associated with Echinacea, but it may have been caused by cold or flu symptoms for which the Echinacea products were administered. [35]
The symptoms of disease appear as pathogenic bacteria damage host tissues or interfere with their function. The bacteria can damage host cells directly or indirectly by provoking an immune response that inadvertently damages host cells, [ 21 ] or by releasing toxins .
Erdosteine showed in vivo and in vitro synergistic activity with antibiotics, against bacterial adhesiveness, in patients with respiratory infections. [ 2 ] [ 3 ] Several clinical studies underline that, when given in combination with antibiotics, erdosteine does not interfere with their activity but improve their effects, causing an increase ...
The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...
