Evaluation of causative organisms and their resistance in a university hospital setup over a time period of four years.
David J Apple Laboratory, Dept. of Ophthalmology, University Hospital, Heidelberg, Germany
Methods: In a retrospective design the microbiological results of 1143 probes were analyzed for their causative organisms and their resistance over a time period of four years. Changes in resistance were evaluated and compared to the available topical pharmaceutics.
Over the whole time period the highest amount of causative organisms was found for coagulase-negative staphylococcus (54%), followed by the staphylococcus aureus (19%). Greening streptococcus, streptococcus pneumonia, corynebacterium, haemophilus influence were found in a range of 6 to 8%. Other causative organisms like enterococcus, pseudomonas, non-hamolysing streptococcus and also MRSA could only be found in a range between 1 - 2%. Resistance underwent little changes during follow up time.
Bacterial infections are still a danger in any field of medicine. Our analyzes show, that there is a wide spectrum of causative organisms and their infections in the daily clinic. Often only the normal skin flora can be detected. Sometimes resistance is proven for all available antibiotics, still in the field of ophthalmology, most infections can be healed by topical intervention.
