Susceptibility And Resistance

Introduction: Infections caused by Staphylococcus species can spread not only in hospitals but also in the community and in other healthcare institutions. These organisms were known for its capability to acquire resistance to various classes of antibiotics. Methods: The antibiotic susceptibility and resistance rates of S. aureus strains isolated from numerous clinical samples at a public hospital in Al-kharj city were collected from the monthly antibiogram prepared by the laboratory department in the hospital. Results: The bacterial culture results found that there were 450 Staphylococcus species; the majority of bacteria were Staphylococcus aureus. Some medications such as Vancomycin, Linezolid still very effective in treating Staphylococcus infections. Conclusion: S. aureus infections were common in Alkharj city and the resistance is widespread for staphylococci species, mainly MRSA. To reduce the resistance rate antimicrobial stewardship programs should be implemented and antibiotic susceptibility should be monitored continuously.

Susceptibility And Resistance

Background. Staphylococus aureus (S. aureus) colonization is revealed in 80-84% of patients with atopic dermatitis (AD). There are no results on S. aureus susceptibility to antibiotics in children with AD within the period 2002-2004 to 2007-2009 years. Methods. S. aureus susceptibility to antibiotics was evaluated in 62 children with AD in 2002-2004 years and in 199 children in 2007-2009 years. S. aureus susceptibility and resistance to antibiotics were evaluated as frequencies (q) and their 95% confidential intervals (CI 95%) with MS «Excell». results. S. aureus antibiotic susceptibility in AD children is increased to ciprofloxacin since 2002-2004 to 2007-2009 [0,54 (0,42..0,67) /0,85 (0,80..0,91)] and is not changed to ceftriaxone [0,57 (0,44..0,70) /0,64 (0,57..0,71)], oxacillin [0,75 (0,64..0,86)/0,71 (0,64..0,78)] and cefuroxime [0,61 (0,49..0,74)/0,58 (0,36..0,80)]. Erythromycin susceptibility of S. aureus is 7 times reduced [0,71 (0,60..0,82)/0,10 (0,06..0,14)]; chloramphenicol susceptibility is 2 times reduced [0,79 (0,69..0,90)/0,33 (0,09..0,57)]. There is a decline of S. aureus antibiotic susceptibility to penicillin, ampicillin, linkomycin. Conclusion. Ceftriaxone may be the antibiotic of choice in children with severe infected AD. Oxacillin and cefuroxime should be recommended as an alternative choice.

Staphylococcus aureus (S. aureus) has long been recognized as an important human pathogen causing many severe diseases. It is also a part of human normal flora with its ecological niche in the human anterior nares. This study focused on screening S. aureus nasal carriage in community and its relationship to human physiological and pathological factors which have not been studied in Vietnam previously. Two hundred and five volunteers in Ho Chi Minh City from 18 to 35 and over 59 years old both male and female participated in the study. Result showed that the prevalence of S. aureus nasal carriage in southern Vietnamese community was relatively low, only 11.2% (23/205), much lower than that in other international reports on human S. aureus. In addition, nasal carriage of the older age group (> 59 years old, 13.7%) was higher than that of younger age (18-35 years old, 10.4%). Other potential risk factors such as gender, career, height, weight, history of antibiotic usage, daily nasal wash, use of nasal medication sprays, acne problems, smoking and nasal problems showed no significant impact on S. aureus carriage. The obtained S. aureus nasal isolates were all sensitive to vancomycin. Lincomycin and tetracycline had low resistance rate with 4.3 % and 17.4 %, respectively. However, the isolates showed particularly high rate of multidrug resistance (54.2%) In summary, our data provided researchers an overview on S. aureus nasal carriage and antibiotic susceptibility profile of the community- isolated S. aureus in Vietnam. This would serve as valuable information on assessing risk of community-acquired S. aureus infections.

Diabetic foot infections (DFIs) are a significant health issue and a common complication among patients with diabetes. To develop antibiotic therapy for these high-risk patients, the current study evaluates the scope of DFIs and identifies the causing microbes. It also measures spectrum and antibiotic susceptibility of the pathogens isolated from adults with DFIs in Saudi Arabia. To achieve the study objectives, a cross-sectional study was implemented and the baseline characteristics for 44 patients with DFIs were defined. Optimal aerobic and anaerobic microbiological techniques were utilized to culture specimens isolated from infected foot ulcers. The standard microbiological methods were employed to identify the bacterial isolates and antibiotic susceptibility testing was conducted following the procedures of the Clinical and Laboratory Standards Institute (CLSI). Results showed that 12 microorganisms were isolated from the participants’ diabetic foot ulcers. Staphylococcus Aureus was ranked first because it appeared in 29 (65.9%) cases. Streptococcus Agalactiae was ranked second and multi-microbial infections were also found. Most of the organisms were susceptible to Vancomycin, Ciprofloxacin, and Cefalexin, but they were resistant to Methicillin, Gentamicin, and Ampicillin antibiotics. Staphylococcus Aureus was most sensitive to Ciprofloxacin, while it was resistant to Methicillin. About 10% of the isolates were multidrug-resistant. The study concludes that while Vancomycin should be used empirically for Gram-positive isolates, Ciprofloxacin can be taken into consideration for most of the Gram-negatives aerobes. Based on including various microorganisms and the advent of multidrug-resistant strains, proper culture and sensitivity testing are necessary prior to the empirical therapy.

Objectives: To isolate methicillin resistant Staphylococcus aureus (MRSA) from anterior nares of dairy workers and dairy products and assess the antibiotic susceptibility pattern of the isolates. Methods: Swab samples collected from anterior nares of dairy workers and dairy product (butter) were inoculated into mannitol salt agar and incubated at 37ºC for 24 hours. Identification was done based on colony characteristics, Gram's staining, catalase, oxidase and coagulase test. Antibiotic susceptibility testing was done by modified Kirby Bauer disc diffusion method. MRSA was confirmed by using cefoxitin disc. Results: A total of 109 S. aureus (98 from dairy workers and 11 from butter samples) were isolated. Out of them 32 MRSA were isolated from dairy workers and 4 from butter samples. The association between age group and MRSA was found insignificant (p = 0.115). The association of MRSA between male and female workers was found significant (>0.05). About 86% of the MRSA isolates were susceptible to Gentamicin (86.11%) followed by Ciprofloxacin (77.78%). Conclusion: Detection of MRSA among dairy workers and dairy products warrants proper handling and adequate control measures to prevent transmission of MRSA from dairy industry.

(1) Background: nasopharynx colonization by resistant Staphylococcus aureus and Streptococcus pneumoniae can lead to serious diseases. Emerging resistance to antibiotics commonly used to treat infections due to these pathogens poses a serious threat to the health system. The present study aimed to determine the antibiotic susceptibility of S. aureus and S. pneumoniae isolates from the febrile children’s nasopharynx under 5 years in Nanoro (Burkina Faso). (2) Methods: bacterial isolates were identified from nasopharyngeal swabs prospectively collected from 629 febrile children. Antibiotic susceptibility of S. aureus and S. pneumoniae isolates was assessed by Kirby–Bauer method and results were interpreted according to the Clinical and Laboratory Standard Institute guidelines. (3) Results: bacterial colonization was confirmed in 154 (24.5%) of children of whom 96.1% carried S. aureus, 3.2% had S. pneumoniae, and 0.6% carried both bacteria. S. aureus isolates showed alarming resistance to penicillin (96.0%) and S. pneumoniae was highly resistant to tetracycline (100%) and trimethoprim–sulfamethoxazole (83.3%), and moderately resistant to penicillin (50.0%). Furthermore, 4.0% of S. aureus identified were methicillin resistant. (4) Conclusion: this study showed concerning resistance rates to antibiotics to treat suspected bacterial respiratory tract infections. The work highlights the necessity to implement continuous antibiotic resistance surveillance.

SummaryThe present study was undertaken to investigate the frequency of the nasal carrier rate ofStaphylococcus aureus. The investigation was performed on 104 healthy persons. The total number of swabs performed was 1498 and this resulted in isolation of 522S. aureusstrains. All strains have been identified, tested for antibiotic susceptibility, and phage-typed. The carrier-index (number of positive swabs/number of total swabs for each individual person) was compared with different sampling and culturing methods, phage type, age, and resistance to antibiotics. There was statistical difference in carrier rate according to sex (P·05). Among the 104 persons 15 (14·4%) were persistent carriers, 17 (16·3%) intermittent carriers, 55 (52·9%) occasional carriers and 17 (16·3%) non-carriers. Among intermittent and occasional carriers the phage-type distribution was different from theS. aureusstrains isolated from Danish hospitalized patients in 1992, while the persistent carriers had similar phage-type distribution.
