An epidemic of herpes simplex virus type 1 occurred in 60 of 175 wrestlers (34%) attending a four-week intensive training camp. Five of these 60 patients (8%) developed ocular involvement that included follicular conjunctivitis, blepharitis, and phlyctenular disease. Cultures of the conjunctiva and eyelid vesicles were positive for herpes simplex virus type 1 in four of the five patients with ocular disease. The viral isolates were compared by restriction-endonuclease analysis, which disclosed that three of the four isolates were the same strain. None of the patients had corneal involvement and there has been no evidence of viral recurrence to date. Herpes simplex virus type 1 is a health risk for wrestlers, and ocular infections are part of the clinical spectrum. Prompt diagnosis and appropriate management of the outbreak may reduce the severity of the outbreak transmission.

Severe infections due to methicillin-resistant Staphylococcus aureus (MRSA) have been increasingly recognized in virtually all fields of veterinary medicine. Our objective was to study the occurrence, phylogenetic relationships and antimicrobial resistance properties of MRSA isolated from ocular surfaces of horses prior to invasive procedures. Within a 49-week sampling period, ocular swabs obtained from 46 eyes of 44 horses, including eyes with clinical signs of conjunctivitis/blepharitis, keratitis or uveitis were screened for the presence of S. aureus. As a result, seven samples were positive for S. aureus (15.2%), with six of them being classified as MRSA (13%). In addition, all isolates were resistant or showed reduced susceptibility to tetracyclines, the aminoglycosides gentamicin and kanamycin, fluoroquinolones, and the combination sulfamethoxazole/trimethoprim. Since a very close relationship between the MRSA isolates was assumed after pulsed-field gel electrophoresis employing the restriction endonuclease ApaI, whole genome sequencing (WGS) was used to shed more light on the phylogenetic relationships and the molecular composition of all MRSA isolates. Analysis of WGS data revealed closely related MRSA belonging to sequence type 398, spa type t011 and dru type dt10q, harboring an SCCmec IV element and the Staphylococcus aureus pathogenicity island SaPIbov5. Moreover, all MRSA were positive for a beta-hemolysin converting phage carrying genes of the immune evasion cluster (IEC). Since cases of eye infections due to MRSA were often associated with fatal outcomes, more research is needed with respect to the origin of MRSA isolated from ocular surfaces to implement sufficient barrier and infection control measures.
