Methicillin-Resistant Staphylococcus aureus: Risk for General Infection and Endocarditis Among Athletes. Antibiotics (Basel) 2020; 9:E332.

Abstract
The first studies on Staphylococcus aureus (SA) infections in athletes were conducted in the 1980s, and examined athletes that perform in close physical contact, with particular attention to damaged or infected skin. Recent studies have used molecular epidemiology to shed light on the transmission of SA in professional athletes. These studies have shown that contact between athletes is prolonged and constant, and that these factors influence the appearance of infections caused by SA. These results support the need to use sanitary measures designed to prevent the appearance of SA infections. The factors triggering the establishment of SA within professional sports groups are the nasal colonization of SA, contact between athletes and sweating. Hence, there is a need to use the most modern molecular typing methods to evaluate the appearance of cutaneous SA disease. This review aims to summarize both the current SA infections known in athletes and the diagnostic methods employed for recognition, pointing to possible preventive strategies and the factors that can act as a springboard for the appearance of SA and subsequent transmission between athletes.

High Occurrence of Staphylococcus aureus Isolated from Fitness Equipment from Selected Gymnasiums. JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2018; 2018:4592830. [PMID: 30245728 PMCID: PMC6136567 DOI: 10.1155/2018/4592830] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/29/2018] [Revised: 07/17/2018] [Accepted: 08/02/2018] [Indexed: 11/18/2022]
Abstract
Introduction Staphylococcus aureus is a leading cause of cutaneous bacterial infection involving community. Methods In this study, a total of 42 swab samples were collected from the surface of various fitness equipment such as back machines, exercise mats, dip stations, dumbbells, and treadmills. Identification of the bacterial isolates was conducted using biochemical tests and further analysed molecularly using the PCR method targeting nuc gene (270 bp). The nuc gene encodes for the thermonuclease enzyme, a virulent factor of S. aureus. Results The findings showed 31 out of 42 swab samples (73.81%) were positive with S. aureus. Conclusion This study showed that gymnasium equipment is a potential reservoir for S. aureus and might play an important role in transmitting the pathogen to humans. Objective This study was undertaken to assess the presence of S. aureus on the surface of fitness equipment from selected gymnasiums in Kuching and Kota Samarahan, Sarawak (Malaysia).

Abstract
OBJECTIVE To measure transmission frequencies and risk factors for household acquisition of community-associated and healthcare-associated (HA-) methicillin-resistant Staphylococcus aureus (MRSA). DESIGN Prospective cohort study from October 4, 2008, through December 3, 2012. SETTING Seven acute care hospitals in or near Toronto, Canada. PARTICIPANTS Total of 99 MRSA-colonized or MRSA-infected case patients and 183 household contacts. METHODS Baseline interviews were conducted, and surveillance cultures were collected monthly for 3 months from household members, pets, and 8 prespecified high-use environmental locations. Isolates underwent pulsed-field gel electrophoresis and staphylococcal cassette chromosome mec typing. RESULTS Overall, of 183 household contacts 89 (49%) were MRSA colonized, with 56 (31%) detected at baseline. MRSA transmission from index case to contacts negative at baseline occurred in 27 (40%) of 68 followed-up households. Strains were identical within households. The transmission risk for HA-MRSA was 39% compared with 40% (P=.95) for community-associated MRSA. HA-MRSA index cases were more likely to be older and not practice infection control measures (P=.002-.03). Household acquisition risk factors included requiring assistance and sharing bath towels (P=.001-.03). Environmental contamination was identified in 78 (79%) of 99 households and was more common in HA-MRSA households. CONCLUSION Household transmission of community-associated and HA-MRSA strains was common and the difference in transmission risk was not statistically significant.

Abstract
Background: Superficial skin injuries are considered minor, and their incidence is probably underestimated. Insight into the incidence and mechanism of acute skin injury can be helpful in developing suitable preventive measures and safer playing surfaces for soccer and other field sports. Purpose: To gain insight into the incidence and severity of skin injuries related to soccer and to describe the skin injury mechanism due to player-surface contact. Study Design: Systematic review; Level of evidence, 4. Methods: The prevention model by van Mechelen et al (1992) combined with the injury causation model of Bahr and Krosshaug (2005) were used as a framework for the survey to describe the skin injury incidence and mechanism caused by player-surface contact. Results: The reviewed literature showed that common injury reporting methods are mainly based on time lost from participation or the need for medical attention. Because skin abrasions seldom lead to absence or medical attention, they are often not reported. When reported, the incidence of abrasion/laceration injuries varies from 0.8 to 6.1 injuries per 1000 player-hours. Wound assessment techniques such as the Skin Damage Area and Severity Index can be a valuable tool to obtain a more accurate estimation of the incidence and severity of acute skin injuries. Conclusion: The use of protective equipment, a skin lubricant, or wet surface conditions has a positive effect on preventing abrasion-type injuries from artificial turf surfaces. The literature also shows that essential biomechanical information of the sliding event is lacking, such as how energy is transferred to the area of contact. From a clinical and histological perspective, there are strong indications that a sliding-induced skin lesion is caused by mechanical rather than thermal injury to the skin.

Abstract
BACKGROUND Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is increasing in incidence and manifests as skin and soft tissue infections including furuncles. The majority of studies have focused on the epidemiology of single furuncles and not recurrent disease. There is a lack of data concerning the incidence of furunculosis outside the U.S.A. OBJECTIVES This report reviews the literature of recurrent furunculosis and the impact of CA-MRSA on the disease. METHODS Article citations were searched within PubMed. Search terms used were 'furunculosis', 'recurrent furunculosis', 'skin abscess' and 'recurrent boils'. Articles were discarded if they did not refer to furunculosis secondary to S. aureus. RESULTS A total of 1515 articles were initially retrieved with the term 'furunculosis', 77 with the term 'recurrent furunculosis', 2778 with the term 'skin abscess', and 1526 with the term 'recurrent boils'. After excluding articles not referring to S. aureus furunculosis, 86 articles were included for this review. CONCLUSIONS Furunculosis is increasing within the U.S.A. secondary to the CA-MRSA epidemic and the resistant organism's close association with the Panton-Valentine leucocidin (PVL) virulence factor. PVL is associated with follicular infections in general, having its strongest association with furunculosis and its recurrence. The majority of furuncles in the U.S.A. are caused by CA-MRSA, while elsewhere in the world they are caused by methicillin-sensitive S. aureus. Nasal carriage of S. aureus is the primary risk factor for recurrent furunculosis and occurs in 60% of individuals.

Abstract
SUMMARYAn outbreak of methicillin-resistant Staphylococcus aureus (MRSA) skin and soft tissue infections (SSTIs) occurred in a college football team in August 2006. Of 109 players on the team roster, 88 (81%) were interviewed during a cohort investigation. Twenty-five cases were identified, six of which were culture-confirmed. Available culture isolates were typed by pulsed-field gel electrophoresis (PFGE), which identified two different MRSA strains associated with the outbreak. Playing positions with the most physical contact (offensive linemen, defensive linemen, and tight ends) had the greatest risk of infection [risk ratio (RR) 5·1, 95% confidence interval (CI) 2·3–11·5. Other risk factors included recent skin trauma (RR 1·9, 95% CI 0·95–3·7), use of therapeutic hydrocollator packs (RR 2·5, 95% CI 1·1–5·7), and miscellaneous training equipment use (RR 2·1, 95% CI 1·1–4·1). The outbreak was successfully controlled through team education and implementation of improved infection-control practices and hygiene policies.

Abstract
Recent outbreaks of infectious diseases in athletes in competitive sports have stimulated considerable interest. The environments in which these athletes compete, practice, receive therapy for injuries, and travel, both domestically and internationally, provide varied opportunities for the transmission of infectious organisms. The purpose of this medical literature review is to identify the agents most commonly reported in the medical literature as responsible for infectious disease outbreaks in specific sports and their modes of transmission and to guide targeted prevention efforts. A literature review of English-language articles in medical publications that reported outbreaks of infectious diseases in competitive athletes was conducted in PubMed MEDLINE from 1966 through May 2005. Outbreaks that were solely food borne were excluded. Fifty-nine reports of infectious disease outbreaks in competitive sports were identified in the published medical literature. Herpes simplex virus infections appear to be common among wrestlers and rugby players, with no single strain responsible for the outbreaks. Methicillin-resistant Staphylococcus aureus was responsible for several recent outbreaks of soft tissue and skin infections among collegiate and professional athletes. The most common mode of transmission in outbreaks was direct, person-to-person (primarily skin-to-skin) contact. Blood-borne exposure was implicated in 2 confirmed outbreaks of hepatitis. Airborne and vector transmissions were rarely reported. This review provides an overview of infectious disease outbreaks thought to be either serious enough or unusual enough to report. Appropriate surveillance of the frequency of infections will allow sports medicine staff to identify outbreaks quickly and take necessary measures to contain further transmission and prevent future outbreaks.

Abstract
Participants of contact sports are at risk for outbreaks of skin and soft tissue infection. Causes of reported outbreaks include Staphylococcus aureus, herpes simplex virus, Streptococcus pyogenes, and several fungi. Although once thought of solely as a nosocomial pathogen, methicillin-resistant Staphylococcus aureus has been identified as an emerging problem in the community, particularly in the athletic population. Despite a recent increase in reported outbreaks of community-acquired methicillin-resistant Staphylococcus aureus soft tissue infection in athletic teams, many sports medicine physicians are unfamiliar with the epidemiology of this pathogen. It is spread via person-to-person contact and is harbored within the anterior nares and on the skin of carriers. Outbreaks of community-acquired methicillin-resistant Staphylococcus aureus soft tissue infection are not treated by traditional beta-lactam antibiotics, and they can be difficult to eradicate. Such infections have been associated with significant morbidity, with up to 70% of involved team members requiring hospitalization and intravenous antibiotics. A thorough understanding of community-acquired methicillin-resistant Staphylococcus aureus is essential for the sports medicine physician to properly identify, treat, and control infectious outbreaks.

Abstract
A retrospective review of an outbreak of community-acquired methicillin-resistant Staphylococcus aureus soft tissue infections in a high school football team was conducted. Thirteen players had 20 infections. Available community-acquired methicillin-resistant S. aureus isolates showed identical antibiotic susceptibility and field inversion gel electrophoresis analysis band patterns. Nasal cultures and mupirocin were ineffective at predicting and controlling infection, respectively. Infections treated with beta-lactam antibiotics were at risk for recurrence.

Abstract
Between 1 February and 15 April 2002, 95 patients were admitted to Gaston Bourret Territorial Hospital (New Caledonia, France) for drainage of community-acquired soft tissue abscesses. Staphylococcus aureus was detected in 68 cases (72%). Two-thirds of the patients with S. aureus infection had furuncles, which were located on the limbs in 82% of cases. The median interval between symptom onset and hospital admission was 5.7 days. Three-quarters of the patients were Melanesians living in tribes. Fifty-four S. aureus isolates were screened for toxin genes. Panton-Valentine leucocidin (PVL) genes were detected in 48 isolates (89%), the exfoliative toxin A gene was detected in 1 isolate, and no toxin genes were detected in 4 isolates. S. aureus nasal carriage was detected in 39.7% of patients with S. aureus infections. Two infecting S. aureus strains and two nasal carriage strains were resistant to methicillin. Comparative pulsed-field gel electrophoresis, performed in 16 cases, showed that five of six patients with PVL-positive nasal carriage strains were infected by the same strains. In contrast, 8 of 10 patients with PVL-negative nasal carriage strains were infected by PVL-positive strains. PVL genes thus appear to be a major virulence factor in both primary and secondary S. aureus skin infections.

Abstract
BACKGROUND Athletics-associated methicillin-resistant Staphylococcus aureus (MRSA) infections have become a high-profile national problem with substantial morbidity. METHODS To investigate an MRSA outbreak involving a college football team, we conducted a retrospective cohort study of all 100 players. A case was defined as MRSA cellulitis or skin abscess diagnosed during the period of 6 August (the start of football camp) through 1 October 2003. RESULTS We identified 10 case patients (2 of whom were hospitalized). The 6 available wound isolates had indistinguishable pulsed-field gel electrophoresis patterns (MRSA strain USA300) and carried the Panton-Valentine leukocidin toxin gene, as determined by polymerase chain reaction. On univariate analysis, infection was associated (P<.05) with player position (relative risk [RR], 17.5 and 11.7 for cornerbacks and wide receivers, respectively), abrasions from artificial grass (i.e., "turf burns"; RR, 7.2), and body shaving (RR, 6.1). Cornerbacks and wide receivers were a subpopulation with frequent direct person-to-person contact with each other during scrimmage play and drills. Three of 4 players with infection at a covered site (hip or thigh) had shaved the affected area, and these infections were also associated with sharing the whirlpool > or =2 times per week (RR, 12.2; 95% confidence interval, 1.4-109.2). Whirlpool water was disinfected with dilute povidone-iodine only and remained unchanged between uses. CONCLUSIONS MRSA was likely spread predominantly during practice play, with skin breaks facilitating infection. Measures to minimize skin breaks among athletes should be considered, including prevention of turf burns and education regarding the risks of cosmetic body shaving. MRSA-contaminated pool water may have contributed to infections at covered sites, but small numbers limit the strength of this conclusion. Nevertheless, appropriate whirlpool disinfection methods should be promoted among athletic trainers.

Abstract
Staphylococcus aureus causes a variety of minor diseases but also is responsible for staphylococcal pneumonia and sepsis, both of which can be fatal. It is thought to be responsible for many of the pneumonia deaths associated with the influenza pandemics of the 20th century. The introduction of penicillin in the 1940s greatly improved the prognosis for patients with severe staphylococcal infections. However, after a few years of clinical use, most staphylococcal strains were able to hydrolyze penicillin by producing b-lactamases, making penicillin a useless antibiotic to treat staphylococcal infections caused by b-lactamase-producing S aureus. Methicillin, a semisynthetic penicillin introduced in 1959, was specifically designed to be resistant to b-lactamase degradation, but resistance developed soon after its introduction into clinical practice. Methicillin-resistant S aureus (MRSA) was first reported in the United Kingdom in 1961, followed by reports from other European countries, Japan, and Australia. The first reported case of MRSA in the United States was in 1968. Currently, MRSA is an important pathogen in nosocomial infections and is a problem in hospitals worldwide, and it is increasingly recovered from nursing home residents with established risk factors. More recently, community acquired MRSA infections have been documented among healthy individuals with no recognizable risk factors, and it seems clear that community-acquired MRSA (CA-MRSA) strains are epidemiologically and clonally unrelated to hospital-acquired strains. This review focuses on the epidemiology, clinical significance, and virulence markers of CA-MRSA infections.

Abstract
Athletes competing in a wide variety of sports are at risk of contracting and spreading bacterial skin infections. Bacteria proliferate in environments of wet, macerated skin that is repeatedly abraded against competing athletes, equipment, clothing, or objects in the field of play. Common infections include impetigo, folliculitis, furunculosis, pitted keratolysis, and otitis externa. Diagnosis and treatment are often straightforward and vary little from care for nonathletes. However, knowledge of preventive strategies and return-to-play criteria, as outlined by the National Collegiate Athletic Association, are paramount for clinicians who care for competitive athletes.

Abstract
Infections occur in childhood and adolescent athletes just as they do in all children and adolescents. Because of the sports environment, and in some instances the sport itself, athletes can be prone to infections that will alter their athletic performance or present risks to other athletes. Recognition of the infectious risks related to sports and the options for their treatment or, better yet, prevention, can help young athletes perform to their utmost potential.

Abstract
The most common injuries afflicting the athlete affect the skin. The list of sports-related dermatoses is vast and includes infections, inflammatory conditions, traumatic entities, environmental encounters, and neoplasms. It is critical that the sports physician recognises common and uncommon skin disorders of the athlete. Knowledge of the treatment and prevention of various sports-related dermatoses results in prompt and appropriate care of the athlete. Infections probably cause the most disruption to individual and team activities. Herpes gladiatorum, tinea corporis gladiatorum, impetigo, and furunculosis are sometimes found in epidemic proportions in athletes. Vigilant surveillance and early treatment help teams avoid these epidemics. Fortunately, several recent studies suggest that pharmacotherapeutic prevention may be effective for some of these sports-related infections. Inflammatory cutaneous conditions may be banal or potentially life threatening as in the case of exercise-induced anaphylaxis. Athletes who develop exercise-induced anaphylaxis may prevent outbreaks by avoiding food before exercise and extreme temperatures while they exercise. Almost all sports enthusiasts are at risk of developing traumatic entities such as nail dystrophies, calluses and blisters. Other more unusual traumatic skin conditions, such as talon noire, jogger's nipples and mogul's palm, occur in specific sports. Several techniques and special clothing exist to help prevent traumatic skin conditions in athletes. Almost all athletes, to some degree, interact with the environment. Winter sport athletes may develop frostbite and swimmers in both fresh and saltwater may develop swimmer's itch or seabather's eruption, respectively. Swimmers with fair skin and light hair may also present with unusual green hair that results from the deposition of copper within the hair. Finally, athletes are at risk of developing both benign and malignant neoplasms. Hockey players, surfers, boxers and football players can develop athlete's nodules. Outdoor sports enthusiasts are at greater risk of developing melanoma and non-melanoma skin cancer. Athletes spend a great deal of time outdoors, typically during peak hours of ultraviolet exposure. The frequent use of sunscreens and protective clothing will decrease the athlete's sun exposure. It is critical that the sports physician recognises common and uncommon skin disorders of the athlete. Knowledge of the treatment and prevention of various sports-related dermatoses results in prompt and appropriate care of the athlete.

Abstract
Outbreaks of invasive infection caused by methicillin-susceptible and methicillin-resistant Staphylococcus aureus occur in hospitals, long term care institutions, and in patients discharged from these settings. In contrast, epidemic S. aureus infection has not been reported in well persons in the community. Here, we describe a group of healthy young adults who resided in the same neighborhood and participated together in school sports, and who developed serious S. aureus infections within 3 weeks of each other, suggesting a true community outbreak. Timely use of molecular epidemiological tools, however, demonstrated that their illnesses were caused by unrelated bacterial strains.

Abstract
The objective of this article has been to focus on the more common infectious diseases that the physician caring for athletes may encounter in the office practice of sports medicine. Clearly the physician plays a critical role in treatment and prevention through early recognition and intervention when appropriate. Fortunately, being a fairly young, healthy athletic population, these patients respond well to treatment. It is critical that physicians caring for athletes take an active role to educate and counsel their patients on appropriate preventive measures and give clear return to participation recommendations. Advice should be based on consideration of each athlete's unique situation as well as up-to-date knowledge concerning the particular infectious disease process involved and appropriate treatment options.

Abstract
Coaches and athletic team physicians have provided anecdotal information and case studies to support their beliefs that athletes may be unusually prone to illness during strenuous training or competition. Many athletes, in contrast, believe that physical activity improves their resistance to infectious disease. However, it is generally agreed that the stress of competition may make athletes temporarily more susceptible to infectious illness. A review of the literature shows that upper respiratory tract infections and skin infections are more prevalent in top level athletes than in the general population, particularly during periods of intensive training. Exercise induced changes occur in both the innate and adaptive components of the immune system; however, the relative importance of each component is unknown. Strenuous exertion and contact sports may compromise host defence both by reducing physical protection and by impairing immunosurveillance. Skin lacerations, vigorous sweating and maceration of the dermis impair the defence normally provided by the skin surface. In addition, adverse changes in soluble and cellular components of the immune system can increase susceptibility to infection. Persistence with strenuous training during an infectious illness can have deleterious effects; not only is athletic performance impaired, but the severity of the disease process can be augmented.

Abstract
BACKGROUND AND METHODS Herpes simplex virus type 1 (HSV-1) has been identified as a cause of cutaneous or ocular infection among athletes involved in contact sports; in this context it is known as herpes gladiatorum. In July 1989, we investigated an outbreak among 175 high-school wrestlers attending a four-week intensive-training camp. Cases of infection were identified by review of medical records, interview and examination of the wrestlers, and culture of skin lesions. Oropharyngeal swabs were obtained for HSV-1 culture, and serum samples for HSV-1 serologic studies. HSV-1 isolates were compared by restriction-endonuclease analysis. RESULTS HSV-1 infection was diagnosed in 60 wrestlers (34 percent). The lesions were on the head in 73 percent of the wrestlers, the extremities in 42 percent, and the trunk in 28 percent. HSV-1 was isolated from 21 wrestlers (35 percent), and in 39 (65 percent) infection was identified by clinical criteria. Five had conjunctivitis or blepharitis; none had keratitis. Constitutional symptoms were common, including fever (25 percent), chills (27 percent), sore throat (40 percent), and headache (22 percent). The attack rate varied significantly among the three practice groups, ranging from 25 percent for practice group 1 (lightweights) to 67 percent for group 3 (heavyweights). Restriction-endonuclease analysis identified four strains of HSV-1 among the 21 isolates. All 10 isolates from practice group 3 were identical (strain A), and 5 of 7 isolates from practice group 2 (middleweights) were identical (strain B), which suggested concurrent transmission of different strains within different groups. HSV-1 was not isolated from any oropharyngeal swabs. CONCLUSIONS Herpes gladiatorum may cause substantial morbidity among wrestlers, and it is primarily transmitted by direct skin-to-skin contact. Prompt identification and exclusion of wrestlers with skin lesions may reduce transmission.
