Ocular Microbiology

by PK Mukherjee, Preeti Bandyopadya

Last few decades have witnessed tremendous change in the field of microbiology in general and ophthalmology in particular. The behavior of the microbes have undergone many variations. The two most probable causes being the changes in the organism and its ability to mutate. Many organisms have developed newer protective mechanisms against known antimicrobials. The second cause is the changed immunity in the hosts. Some organisms that were thought to be commensals are proving to be the causes of many unsuspected devastations. On one end of the scenario is the emergence of newer and potent drugs that have made management of infections easy, but on the other end is a dismal picture of drug resistance. Common organisms have developed mechanisms to circumvent commonly used older drugs. Clinical presentation of many of the infections and infestations are sufficient to reach a tentative diagnosis which may require simple tests to clinch the presence of the specific organisms. Unfortunately, this is not always possible due to a lack of broad based knowledge of ocular micro-biology in postgraduates and younger teachers. This makes it imperative that the postgraduates in ophthalmology have a broad based knowledge of microbiology. The present book is mainly addressed to those who would find it handy for day-to-day reference. They are expected to consult larger books on microbiology for advanced knowledge.
