Pimple (colloquially known as a zit or spot) is a kind of comedo resulting from excess sebum and dead skin cells getting trapped in the pores of the skin. It causes outbreaks of skin lesions termed as acne1. Acne is a disorder of the sebaceous glands of the skin in which sebum secretions are too much and the glands become plugged and inflamed2. Acne is also known as Acne vulgaris and approximately 45 million people in the United States are suffering with acne, with about 85% prevalence in the youngsters between 15 and 24 years3. It is reported that Staphylococcus aureus and Streptococcus pyogenes cause most of the skin and soft tissues infections4.
Mostly cases of these infections are because of normal skin flora and the severity of the infection is depends on the location of inoculation and kind of microorganism5. If the infection is not treated properly then the minute wound becomes larger and spread to surrounding region resulting into a swollen, cutaneous, inflamed, localized lesion walled by deposition of fibrin by the tissue and the walling off is to stop the Staphylococcal infection from going further6.
Ajayi Adesola Adetutu and team conducted a research to isolate and characterize the strains of Staphylococcus aureus obtained from the student’s pimple and determine the antibiotic susceptibility profile for the strains of Staphylococcus aureus. In this experiment, twenty swab samples were collected from male and female students with obvious signs of pimples in Covenant University, Ota, Ogun State, Nigeria. These samples were then cultured on Mannitol Salt Agar and incubated at 37°C. Afterwards, pure isolates were subjected to Gram staining and other biochemical tests for identification. The isolates were further subjected to antibiotics sensitivity tests by utilizing antibiotic dics.
Macroscopic examination revealed that the organisms were convex, smooth and shiny and the isolates were positive after employing the Gram Staining technique. Moreover, scientists found that the isolates were Coagulase positive, Catalase positive, Urease positive, Citrate positive, Methyl-Red positive, Voges-Proskauer negative and negative upon starch hydrolysis after Biochemical tests. While, the antibiotic susceptibility test exhibited that isolates were resistant to Cotrimazole, Cloxacillin, Erythromycin, Gentamycin, Augmentin, Streptomycin, Tetracycline and Chloramphenicol. Therefore; researchers concluded that the isolates consisted of Staphylococcus aureus and other staphylococci species. For that reason, random use of antibiotics should be avoided to prevent the development of resistant strains of the Staphylococci genera and other pathogenic organisms. These findings will definitely assist to treat staphylococcal pimples infections effectively.
