Methicillin- Resistant staphylococcus aureus in pultury

Methicillin resistant stapyloccocus aureus (MRSA) is a staph bacteria that does not react to certain antibiotics usually causes skin infection but can also cause other infections.MRSA can be fatal.MRSA is resistant to antibiotics including methicillin, oxacillin, penicillin, and amoxicillin. These skin infections can be spread by kin to skin contact , sharing or touching a person personal item with someone infected, or touching a surface that has been in contact with someone with MRSA.
This study was done to determine if MRSA was present in pultury. There was a random selection of farms in Belgium and at each farm there was 5 laying hens sampled and 5 broiler chickens sampled. 10 farms for laying hens and 14 farms for the broiler chickens. The samples were taken from cloaca and nasal cavity. There were many tests ran on these samples. Of all the samples MRSA was not isolated from any of the laying hens. which can either mean that is just isnt present of the laying hen or that it is but in very low numbers. MRSA was isolated from 8 broiler chicken from only 2 of the 14 farms, a relativly low number. Between the nasal and cloaca amples a total of 15 MRSA isolations were found. Of all the 15 isolated they all showed resistant to 7 drugs and suseptible to 7 drugs.Molecular typing showed that all the samples were found to be spa type t1456.
