When the flea is infested with pathogens causing bubonic plague the bacteria multiply in the proventriculus (foregut) of the flea. Bubonic plague causes fever and very throbbing swelling of the lymph glands also called buboes, which is the reason why the disease is called bubonic plague. The disease mainly affects wild rodents, it can also be transmitted to human and other domestic animals through flea bites. Thus even though the disease is historic it still infect and kill thousands of people around the world. It is characterised by geographical foci and extraordinarily adaptation capability which gives it ability to re- emerge even after decades of silence. Received 23 June 2016 accepted 13 September 2016 published 16 September 2016īubonic plague is the bacterial infection caused by Yersinia pestis when the bacteria infect lymphatic system. The results show that bubonic plague canīe eradicated if efforts are made to ensure that there are effective and timely Was globally asymptotically stable when R 0 1. ![]() The Metzler matrix method was used to prove that the DFE Using Jacobian method disease free equilibrium (DFE) point, E 0 was proved to be locallyĪsymptotically stable. Conditions for existence and stability of the equilibrium points areĮstablished. Study, a deterministic model for bubonic plague disease with Yersinia pestis in the environment is developed andĪnalyzed. ![]() Interaction with the infected materials or surfaces in the environment. However, the disease may also be transmitted upon the Serious bacterial disease, mainly transmitted to human beings and rodents
