“…Another study by Laub et al in 2011 [22] on Hungarian students showed that only 2/300 students were positive for MRSA nasal colonization. On the contrary, a study carried out on medical students by Avial et al in 2012 [23] showed a significant increase of 27% to 48% over the six-year period of the students' medical course. In another study by Peichowicz et al in 2011 [24] comparing student populations with clinical exposure and without clinical exposure, the authors found that MRSA colonization was positive only in the clinical students, with an occurrence of 21%, while there was no occurrence in non-clinical students.…”

Introduction: Nosocomial infections are normally hospital acquired. Nasal carriage of Staphylococcus aureus (S. aureus) is very common and may be transmitted via a hand-to-nose route. The objective of the present study was to screen healthcare workers for the colonization of their nasal cavities with MRSA. Methodology: The study group included hospital staff such as nurses, doctors, and technicians. The control group included university students. For isolation, nasal swabs were taken from the volunteers and cultured on mannitol salt agar media selective for S. aureus. Suspected colonies were confirmed by PCR using specific primers for the coagulase and mecA gene. Typing of the coagulase-positive strains was done using restriction fragment length polymorphism (RFLP). Results: The results indicated an incidence rate of 76% among healthcare workers. This is in comparison with students who served as control and were negative for MRSA. Using RFLP, four different types of MRSA were confirmed. Conclusions: The results of this study are alarming. Effective control measures must be formulated and implemented to avoid indiscriminate use of antimicrobials and the spread of these infectious agents in the region.

“…In the public health context the biology and epidemiology of coagulase negative Staphylococcus (StCN) must be accompanied systematically (16,17) . The transmission of these bacteria among animals and humans has been described (5,18) . StCN has the potential to produce severe infection in immune suppressed individuals, including humans (19,20) and transfer genes for multi resistance genes to other bacteria (21) .…”

Effectiveness of Tobramycin and Ciprofloxacin Against Bacterial Isolates in Canine Otitis Externa in Uberaba, Minas Gerais

Canine otitis externa is a common and recurrent disease in domestic dogs. Although not being life threatening, it can result in the overuse of antibiotics, increased bacterial resistance and reduction of options for treatment. This study aimed to determine: the principal characteristics (age, race, and gender) of dogs affected by otitis externa; the most frequently bacteria identified as being associated with it and their antimicrobial resistance profiles. A total of 221 bacterial isolates were identified by morphological staining and biochemical processes and tested against eleven antibiotics. Among the 148 dogs diagnosed with otitis externa, 51.4% (76/148) were males and 48.6% (72/148) females. The cases were detected mainly in dogs with age above 7 years (54.7%; 81/148. Among the races examined, poodles were the most numerous (14.84%; 22/148). The most common bacteria found were: coagulase-negative Staphylococcus (StCN), 33.9% (75/221); coagulase-positive Staphylococcus (StCP), 19% (42/221); Proteus spp., 17.2% (38/221) and Pseudomonas aeruginosa, 9.5% (21/221). Simultaneous resistance to more than three classes of antimicrobials were most frequently detected in P. aeruginosa (61.9%; 13/21) and Proteus spp (39.47%; 15/38). According to data obtained from this study, two veterinary medications found to be most effective for topical treatment were tobramycin and ciprofloxacin.

“…Asymptomatic carriage of S. aureus in healthy individuals has been shown to have a high prevalence, especially in children, young adults, and healthcare workers [ 7 – 10 ]. Medical students represent an important portion of the healthcare staff, whom are in frequent contact with community in general or healthcare environment and may spread the bacteria to other community members or to susceptible patients, respectively [ 10 – 16 ].…”

Introduction. Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) represents a risk for the spread of bacteria. This study characterized the S. aureus isolated from medical students, who were in their clinical rotation at a hospital in the city of Cali. Materials and Methods. 216 students participated in the study and 63 isolates of S. aureus were evaluated for susceptibility and PCR amplification of agr and mecA genes. The origin of MRSA isolates was established by analyzing agr polymorphisms. Results. A total of 29.2% of students were colonized by S. aureus and nasal carriage rate was 23.6% and 14.3% MRSA. Three agr groups (agr II, and agr III) were identified; the agr I group was the most common, with a 35% prevalence; this group is from community origin. Conclusion. The present study demonstrates that medical students carry S. aureus strains, with the threat of spreading them both to community and hospital environments.
