Unfortunately for cockroaches, it is actually the bacteria that is harboured in them that is transmitted to humans as well as other pathogens, including a bacteria called Pseudomonas Aeruginosa which is a multidrug resistant pathogen recognised for its ubiquity, its intrinsically advanced antibiotic resistance mechanisms, and its association with serious illnesses. Hospital-acquired infections include ventilator-associated pneumonia and various sepsis syndromes. Roaches can also spread the Salmonella bacteria which leads to Salmonellosis. Salmonellosis is a symptomatic infection caused by bacteria of the Salmonella type. The most common symptoms are diarrhea, fever, abdominal cramps, and vomiting. This typically occurs between 12 hours and 36 hours after exposure with symptoms lasting from two to seven days. Occasionally more significant disease can result in dehydration. The old, young, and others with a weakened immune system are more likely to develop severe disease.[1] Specific types of Salmonella can result in typhoid fever or paratyphoid fever.
