“…For most people, these bacteria are not etiologic agents of infections. However, for children, immunosuppressed patients, or patients undergoing invasive medical procedures during hospitalization, micrococci, and streptococci can cause severe invasive infections ( Laupland et al 2019 ; Martín Guerra et al 2019 ; Neff et al 2020 ; Zhu et al 2021 ). Contrary to our findings, other studies showed a much lower percentage of contamination with bacilli, micrococci, and streptococci on the surfaces of stethoscopes.…”

The stethoscope remains an indispensable diagnostic tool for medical students. Improper stethoscope hygiene may cause bacterial infections, including hospital-associated infections (HAIs), which challenge the Polish medical system. The study’s main objective was to evaluate the hygiene habits declared by medical students. Moreover, microbiological control with the characteristics of potentially pathogenic microorganisms was performed. The study included 66 medical students from the Faculty of Medicine at the Jagiellonian University Medical College in Cracow, Poland. The participants filled in an anonymous questionnaire. Stethoscope contamination was assessed through isolation, identification, testing of antibiotic resistance, and clonality of the isolates bacterial pathogens. The survey showed that only 30.3% of students cleaned their stethoscopes after each patient, and 1.5% never did this. Of the 66 stethoscopes tested, 100% were positive for bacterial growth. Staphylococcus spp. was the most frequently isolated contaminant (50.5%). The questionnaire results demonstrated the necessity of the validated procedures for cleaning the stethoscopes. Stethoscopes used by medical students are contaminated with numerous bacterial species, including multidrug-resistant organisms. The clonal structure of the MRSA and MRSE populations acquired from stethoscopes has been demonstrated. Our results confirm the possibility that these medical devices mediate the spread of hazardous pathogens in the hospital environment. Practical exercises are essential to forming the correct hygiene habits involving stethoscopes, which enable practicing and checking the correctness of the established skills.

“…It has been noted to be an opportunistic bacterium and immunocompromised patients pose the greatest risk of infection 20,21 . Treatment of M. luteus infection typically involves the use of antibiotics such as penicillin, vancomycin and gentamicin 22 . Cefoxitin has also been successfully used to treat peritonitis as a result of M. luteus infection 23 .…”

Chimwamurombe, First Report of Micrococcus luteus in the Buccal Cavity of Bearded Dragon (Pogona vitticeps) in Namibia, J Pure Appl Microbiol., 2019; 13(4):2123-2127. https://doi.org/10.22207/ JPAM.13.4.24 AbstractCentral bearded dragons, Pogona vitticeps, are ectothermic heliotherms native to dry and arid regions and are often kept as exotic pets in colder less arid countries. They do however, often fall sick resulting in sudden death. This is now known to be caused by bacterial infections such as Listeria monocytogenes and Porphyromonas pogonae sp. This study therefore, aimed to identify microorganisms present in the buccal cavity of the central bearded dragon (P. vitticeps) in Namibia. In order to achieve this, oral swabs were taken from a bearded dragon found in a garden in Windhoek, Namibia and grown in nutrient agar. Colony morphology was described before Gram's staining to differentiate the bacteria. The automated VITEK®2 system was used to identify the bacteria. On nutrient agar, opaque yellow circular colonies were observed after 24hrs incubation at 37°C. A gram-positive coccus shaped bacteria was observed. VITEK®2 analysis identified the bacteria as Micrococcus luteus. There has not been a study on the microbiota of the buccal cavity of the central bearded dragon in Namibia.

“…Ovipin peptide was inhibited the growth of Micrococcus luteus A270 (MIC = 1,94 µM (2,84 µg/mL)), Aspergillus niger (MIC = 31,01 µM (45,5 µg/mL)) and this peptide not was able inhibited the growth of E. coli. M. luteus in general it is founded in skin, mucous membranes and oropharynx, but in immunosuppressed patients this microorganism can triggered bacteremia infection (Martín Guerra et al, 2019). Invasive aspergillosis is also problem serious for a medicine because affect mainly immunocomppromissed individuals or patients which receive immunosuppressive treatments, as also solid organ transplantation (Sugui et al, 2014).…”

The intensive and indiscriminate use of antibiotic has increased cases of microorganisms resistance and becoming a worldwide public health problem. In the last years, from natural sources such as hen egg, have received special attention in the discovery of new bioactive compounds. This study aims to identify and characterize a new peptide from chicken egg of Gallus gallus domesticus. The peptide was isolated and purified by high-performance liquid chromatography (HPLC), and its antimicrobial activity was evaluated through liquid growth inhibition assays. The peptide, Ovipin, presented antimicrobial activity against Gram-positive bacteria, Filamentous fungus and Yeast, not cause significant hemolytic effect against human erythrocytes. The molecular weight and amino acid sequence of the peptide was determined by mass spectrometry (MS). Ovipin primary sequence is YVSPVAIVKGLNIPL and a molecular weight of 1,581.94 Da. Ovipin shows 100% and 93.3%, respectively, sequence similarity with the fragments Apolipoprotein B of Gallus gallus and Apolipoprotein B of five others species of Aves. Our data suggest that Ovipin peptide could be a potential therapeutic candidate to be used in combination with other antimicrobial molecules or an alternative led compound for substitution the conventional antibiotics against infections developed by resistant microorganisms.
