“…Children whose age was in between 3 and 4 years were 3.1 times at risk to be colonized with S. pneumoniae (P = 0.01). This finding was in line with studies conducted in Belgium, Spain, and Ethiopia [10, 24, 25]. The decline in S. pneumoniae colonization rate as age increases could be due to the gradual acquisition of mucosal immunity and reduction of exposure.…”

Objective The aim of this study was to determine the colonization rate of Streptococcus pneumoniae , antimicrobial susceptibility pattern and associated risk factors among children attending kindergarten school in Hawassa, Ethiopia. Results Out of 317 study participants, 68 (21.5%) were colonized with S. pneumoniae . Colonization rate was significantly associated with factors such as age (3 to 4 years old) (P = 0.01), having a sibling whose age was less than 5 years (P = 0.011), sharing a bed with parents (P = 0.005), cooking within bedroom (P = 0.002), and previous hospitalization (P = 0.004). Forty-four (64.6%), 33 (48.5%), and 2942.6%) of S. pneumoniae isolated were resistant to cotrimoxazole, penicillin, and tetracycline respectively.

“…The prevalence of nasal carriers of S. aureus varies greatly between different countries and health professional categories; for example, the prevalence of nasal carriers of S. aureus among different health personnel has been reported to vary between 22.7% to 48% [ 8 – 10 ]. However, in our study, we observed a prevalence of S. aureus among podiatrists of 24.3%, which falls within the prevalence range observed in general population-based studies (17.8–31.6%) [ 4 , 6 ].…”

“…This shows that the longer the exposure to the infectious agent, the more likely one is to be colonized. There are numerous longitudinal studies that corroborate this observation [ 4 , 28 – 30 ], such as a study conducted among medical students at the Complutense University of Madrid. This study found the prevalence of S. aureus and MRSA colonization to be 26.92% and 0%, respectively, for students in their third course of study.…”

“…The prevalence of S. aureus nasal carriage varies by country, profession, and demographic group. In the general population, values range from 17.8% to 21.6% in European countries [ 4 , 5 ] to a prevalence of 31.6% in the US [ 6 ]. A higher prevalence of S. aureus among health professionals has been observed, with values of 52% among physiotherapists [ 7 ], 36–66% among nurses [ 8 , 9 ], and 30.6% among pediatricians [ 10 ], but the prevalence in Doctors of Podiatric Medicine (Podiatrists) as members of the surgical and medical team has not been described yet in any country.…”

BackgroundThis study aimed to estimate the prevalence of methicillin-susceptible and -resistant Staphylococcus aureus (MSSA and MRSA) and methicillin-resistant Staphylococcus epidermidis (MRSE) nasopharyngeal carriage among Doctors of Podiatric Medicine (Podiatrists) and to determine the potential risk factors.MethodsA cross-sectional study was carried out in 2016–2017 among 239 podiatrists in Spain. The presence of MSSA, MRSA, and MRSE was determined by microbiological analysis of nasal exudate and antimicrobial susceptibility was determined. Each podiatrist completed a questionnaire. The questionnaire comprised various parameters such as sex, age, podiatry experience duration, underlying diseases, prior antibiotic treatment, hospitalization during the last year, and use of a protective mask, an aspiration system, or gloves.ResultsThe prevalence of MSSA, MRSA, and MRSE was 23.0%, 1.3%, and 23.8%, respectively. The MSSA prevalence was higher among podiatrists who did not use an aspiration system (32.3%) compared to those who did (19.3%; p = 0.0305), and among podiatrists with respiratory diseases (36.8%) compared to those without (20.8%; p = 0.0272). The MRSE prevalence was higher among men (33.7%) compared to women (8.6%; p = 0.0089), podiatrists aged ≥50 (38.5%) compared to ≤35 (17.8%; p = 0.0101), and podiatrists with ≥15 (39.3%) compared to ≤5 years of podiatry experience (12.5%; p = 0.0015). Among the S. aureus strains, 84.5% were resistant to penicillin, 22.4% to erythromycin, 20.7% to clindamycin, and 12.7% to mupirocin. The MRSE strains were resistant to penicillin (93.0%), erythromycin (78.9%), and mupirocin (73.7%).ConclusionsThe prevalence of S. aureus and S. epidermidis nasal carriage is low among Spanish podiatrists compared to other health professionals.Electronic supplementary materialThe online version of this article (10.1186/s13756-018-0318-0) contains supplementary material, which is available to authorized users.

A tünetmentes hordozás felnőttekben 40-50%, gyerekekben magasabb, 50-70% körüli [10]. A felnőttkori hordozás átlagosan 4-6 hétig perzisztál, dohányosoknál gyakoribb és több szerotípust is involvál-hat egyazon gazdaszervezetben.…”

A Streptococcus pneumoniae (pneumococcus) által okozott infekciók világszerte, így Magyarországon is, tartósan magas morbiditási és mortalitási mutatókkal rendelkeznek a gyermek-és felnőttpopulációban egyaránt. A felnőttkori, hospitalizációt igénylő, otthon szerzett tüdőgyulladások 35-40%-ában a pneumococcus kóroki szerepe igazolható, az S. pneumoniae-pneumoniák 25-30%-a bacteraemiával jár. Az összes fertőzés 5-7%-a fatális kimenetelű, idősek és rizikóbetegek körében az arány meredeken növekedik. A súlyos, invazív formában zajló infekciók esetében a mortalitás elérheti a 20%-ot, a szövődményráta adekvát antibiotikus terápia mellett is jelentős. A szerzők összefoglalják a pneumococcalis betegségek epidemiológiáját, a noninvazív és invazív fertőzések patogenezisét, valamint prezentálják a legfontosabb klinikai aspektusokat esetbemutatásokon keresztül. A betegek rizikóstratifi kációja, a hemokultúrák vétele és a korai antibiotikum-kezelés mellett az aktív immunizáció széles körű alkalmazása segíthet csökkenteni az invazív fertőzések mortalitását. A pneumococcus elleni vakcináció javasolt minden 50 év feletti felnőttnek, illetve minden 18 év feletti krónikus betegnek, aki alapbetegsége miatt fogékony a pneumococcalis infekcióra. Orv. Hetil., 2015, 156(44), 1769-1777. Kulcsszavak: pneumococcus, Streptococcus pneumoniae, invazív pneumococcusbetegség, IPD, konjugált vakcina, poliszacharidvakcina Thousand faces of Streptococcus pneumoniae (pneumococcus) infectionsIncidence and mortality rates of infections caused by Streptococcus pneumoniae (pneumococcus) are high worldwide and in Hungary among paediatric as well as adult populations. Pneumococci account for 35-40% of community acquired adult pneumonias requiring hospitalization, while 25-30% of Streptococcus pneumoniae pneumonias are accompanied by bacteraemia. 5-7% of all infections are fatal but this rate is exponentially higher in high risk patients and elderly people. Mortality could reach 20% among patients with severe invasive pneumococcal infections. Complications may develop despite administration of adequate antibiotics. The authors summarize the epidemiology of pneumococcal infections, pathogenesis of non-invasive and invasive disease and present basic clinical aspects through demonstration of four cases. Early risk stratifi cation, sampling of hemocultures, administration of antibiotics and wider application of active immunization could reduce the mortality of invasive disease. Anti-pneumococcal vaccination is advisable for adults of ≥50 years and high risk patients of ≥18 years who are susceptible to pneumococcal disease.
