" (Sharma, Kunimoto, Garg, & Rao) They believe that he information they are providing will allow the clinician to have a more expansive approach in treating bacterial keratitis and in deciding which secondary antibiotic to use.
The goal of initial antibiotic therapy for bacterial keratitis is the proper selection of a drug which has coverage for the aetiopathogen. Microscopic evaluation of corneal smears can provide insight into the identity of the pathogen, but when smear examination is uninformative the principle of managing bacterial keratitis has been to use antibiotics which have coverage that is sufficiently broad and effective to treat the leading corneal pathogens. (Sharma, Kunimoto, Garg, & Rao)
The main thrust for their interest in this study was to assist the clinician who is in less that ideal setting when faced with treating bacterial keratitis. As mentioned previously the virulent nature of this disease necessitates immediate treatment but the proper facilities are not always present for the clinician to extract corneal scrapings for analysis. Therefore they have provided information that will help this clinician to use secondary antibiotic with a certain degree of judgment when initial antibiotic treatment is unsuccessful. This should provide assistance in all areas of treatment for this...
Furthermore, by increasing the information available regarding success rate of various antibiotic therapies, the authors hope to reduce the time necessary in stopping the further deterioration of the patient's eyesight.
The authors note that one of the obvious limitation of their study is that all the data was gathered from the Hyderabad, India region and that strain of bacteria vary from region to region and some may develop more resistance to specific antibiotic than other, as is their nature to do so. They also do not promote the diagnosis of bacterial keratitis without the proper laboratory test to discover the specific strain when beginning treat and advise against using broad spectrum antibiotics as this further exacerbates the problem of resistance to more and more antibiotic therapies.

Antibiotic resistant organisms has become a topic of much debate in recent years. Antibiotic resistance is a serious concern because of the health care implications that occur as a result of this problem. The purpose of this discussion is to explain antibiotic resistance development in humans. The research will also provide a General overview of specific strains, causes and effects. Antibiotic Resistance Development According to the Centers for Disease Control and Prevention
Conventional approaches including bacterial therapy are becoming less effective and in some cases completely ineffective for combating bacterial infection. Bacteria are evolving, becoming smarter and more virulent, and increasingly resistant to traditional treatment including antibiotic use. While scan the literature available on probiotic use supports use of probiotics for treating drug resistant strains of bacteria in some cases (Diped, 2003). If nothing else the literature supports the use of
Macrolide: Erythromycin This is a proposal describing a study to test the hypothesis that: The macrolide, erythromycin, normally used to treat individuals with community-acquired pneumonia, causes significant antibiotic resistance in patients in Europe but not individuals in the United States. 9 sources To assess the prevalence of macrolide resistance (Erythromycin) among pneumococci in Europe and the United States and difference in frequency of Erythromycin use in both countries for respiratory infections.

Efficiency of Antibiotic Resistance Gene Transfer Mechanisms Upon Exposure to Triclosan Triclosan has become the latest buzz word in the grocery store. It is being hailed as the ultimate biocide and finds its way into many everyday products such as toothpaste and hand soap. Mass media produced a great amount of hype and convinced the general public that this was necessary to protect them from potentially harmful or even fatal bacteria.
One organism, Methicillin-resistant Staphylococcus aureus (MRSA), kills approximately 19,000 Americans annually, which is more than HIV / AIDS, Parkinson's disease, emphysema, and homicide combined (5). In the mid-1980s, the incidence of MRSA isolates was close to zero, and by 1998 the incidence of MRSA was approximately 70% in Japan, 40% in Belgium, 30% in the United Kingdom, and 28% in the United States (1). Every year, 2 million Americans
Antibiotic Resistant Streptococci There are more than thirty different species of streptococcal bacteria. The infections that strep causes in humans range from "strep throat," which is caused by Group A strep and relatively easily treatable, to diseases such as pneumonia and serious wound infections, both of which can prove deadly.(1) Antibiotics were first developed during World War II, and have saved many millions of human lives since then that would have been
