Three medicated soap: Dettol, Delta and Tetmosol were investigated for their antibacterial activities against Staphylococcus aureus. Identification of the antibacterial isolate was by standard microbiological techniques which include colonial / cultural examination, gram staining and biochemical testing such as indole test, methyl red test, voges proskauer, catalase and coagulase test as inoculated in table 1 and table 2 of the result. Zone of inhibition was also examined, Dettol soap has the highest antibacterial activity (8.5mm) against Staphylococcus aureus  as presented in table 3. Significance differences were observed on the different concentration of soap preparation used in the work. Staphylococcus aureus was very sensitive to most of the soaps used. The medicated soaps analyzed have bacteriostatic and bacteriocidal effects on the test organism.






Staphylococcus aureus is a gram-positive coccal bacterium that is a member of the Firmicutes, and is frequently found in the nose, respiratory tract, and on the skin. It is often positive for catalase and nitrate reduction. Although Staphylococcus aureus is not always pathogenic, it is a common cause of skin infections such as abscesses, respiratory infections such as sinusitis, and food poisoning. Pathogenic strain often promote infections by producing potent protein toxins and expressing cell-surface protein that bind and inactivate antibodies. The emergence of antibiotics – resistance forms of Staphylococcus aureus such as MRSA is a World Wide problem in clinical medicine.

Staphylococcus was first identified in 2000 in Aberdeen Scotland by the Surgeon Sir Alexander Ogston in pus from a surgical abscess in a knee joint. This name was later appended to Staphylococcus aureus by Friedrich Julius Rosenbach, who was credited by the official system of nomenclature at this time. An estimated 20% of the human population are long-term carriers of Staphylococcus aureus which can be found as part of the normal skin flora and in the nostrils.

Staphylococcus aureus is the most common species of Staphylococcus to cause Staphylococcus infection and is a successful pathogen due to a combination of nasal carriage and bacterial immunoevasive strategies. Staphylococcus aureus can cause a range of illnesses, from minor skin infections such as pimples, impetigo, boils, cellulities, folliculities, carbuncles, scalded skin syndrome, and abscesses, to life-threatening disease such as pneumonia, meningitis, osteomyelitis, endocarditis toxic shock syndrome, bacteremia, and sepsis.

It’s incidence ranges from skin, soft tissue, respiratory, bone, joint, endovascular to wound infections. It is still one of the five most common causes of hospital acquired infections and is often the cause of post surgical wound infection each year, around 500,000 patients in United State Hospitals contract a Staphylococcal infections like Staphylococcus aureus. Staphylococcus infections may cause disease due to direct infection or due to the production of toxins by the bacterial. Boils, impetigo, food poisoning, cellulitis, and toxic shock syndrome are all examples of diseases that can be caused by Staphylococcus.

Staphylococcus aureus is responsible for many Staphylococcal infections, but it may also occur as a commensal. The presence of Staphylococcus aureus does not always indicate infection. It can survive from hours to weeks, or even months, on dry environmental surfaces, depending on strain. Staphylococcus aureus can infect tissues when the skin or mucosal barriers have been  breached. This can lead to many different types of infections, including pimples, boils and carbuncles (a collection of boils). Staphylococcus aureus infection can spread through contact with pus from an infected wound, skin-to-skin contact with an infected person by producing hyaluronidase that destroy tissues, and contact with objects such as towels, clothing or athletic equipment used by an infected person. Deeply penetrating Staphylococcus aureus infections can be severe. Prosthetic joints put a person at particular risk of septic arthritis, and Staphylococcal endocarditis (infection of the heart valves) and pneumonia. Strains of Staphylococcus aureus can host phages such as PVL (produces Panton-valatine leukocidin), that increases virulence.

Staphylococcus aureus is extremely prevalent in person with Atopic dermatitis. It is mostly found in fertile active places, including the armpit hair and scalp. Large pimples that appear in those areas may exacerbate the infection of lacerated. This can lead to Staphylococcal scalded skin syndrome. A severe form of this Ritter’s disease; can be observed in neonates.

The presences of Staphylococcus aureus in persons with atopic dermatitis is not an indication to treat with oral antibiotics, as evidence has not shown this to give benefit to the patience. The relationship between Staphylococcus aureus and atopic dermatitis is unclear. Evidence shows that attempting to control Staphylococcus aureus with oral antibiotics is not efficacious.

Staphylococcus aureus can survive on dog, cat, and horses, and can cause bumble foot in chickens. Some believe health care workers dogs should be considered a significant sources of antibiotic – resistance Staphylococcus aureus is one of the casual agent of mastitis in dairy cows. Its large polysachainde capsule protects the organism from recognition by the cows immune defenses.

Staphylococcus aureus belong to the family Staphylococcaceae. It affects all known mammalian species, including human. Further due to its ability to effect wide range of species. Staphylococcus aureus can be readily transmitted from one species to another. This includes transmission between human and animals.

Staphylococcus aureus may commonly occur in the environment. Staphylococcus aureus is transmitted through air droplets or aerosol. When an infection person cough or sneezes, he or she releases numerous small droplets of saliva that remain suspended in air. These contain the bacterial and can infect others.

Another common method of transmission is through direct contact with objects that are contaminated by the bacterial or by the bites from infected person or animals. Approximately 30% of healthy humans carry Staphylococcus aureus in their nose, back of the throat and on their skin (Hubert 2000, Alylitte G.A.J 2001).



  • To isolate Staphylococcus aureus from wound infection.
  • To determine the antibacterial activity of three medicated soap on Staphylococcus aureus isolated from wound infection.



Since Dorland (2003) stated that medicated soap have germicidal substances like chloroxylene pothaium, mercunic widede trichloro-carberilide etc incorporated into them in order to greatly their antibacterial activity. It is necessary to investigate the antibacterial activity of three medicated soap (Delta Soap, Tetmosol Soap and Detol Soap) on Staphylococcus aureus isolated from wound infection.



The study is limited to three types of medicated soap which are:

  • Delta Soap
  • Tetmosol soap
  • Detol soap


The result of the project work will indicate the antibacterial activity of medicated. And if favourable, then medicated soap can be used for cleansing and washing the surface of minor wound for the application of further medication.
