Expert Review of Vaccines
|July 31, 2008
Summary
Despite years of research, Staphylococcus aureus vaccines have struggled to prevent infections in humans and cattle. This review examines vaccine targets and reasons for the limited success of Staphylococcus aureus immunotherapeutics.
Area of Science:
- Veterinary Medicine
- Human Medicine
- Infectious Diseases
Background:
- Staphylococcus aureus is a significant pathogen causing human and animal infections, including mastitis in dairy cattle.
- Methicillin-resistant Staphylococcus aureus (MRSA) is an emerging threat, increasing interest in immunotherapeutics.
- Vaccine development for Staphylococcus aureus has been ongoing for decades.
Purpose of the Study:
- To review antigens targeted by Staphylococcus aureus vaccines.
- To explore reasons for the limited efficacy of current Staphylococcus aureus vaccines.
Main Methods:
- Literature review of Staphylococcus aureus vaccine research.
- Analysis of vaccine antigen targets and their effectiveness.
- Discussion of challenges in developing successful Staphylococcus aureus vaccines.
Main Results:
- Several Staphylococcus aureus vaccine formulations have shown partial success in reducing disease severity.
- No Staphylococcus aureus vaccine has demonstrated complete prevention of new infections.
- Key antigens targeted include surface proteins and toxins.
Conclusions:
- Developing effective Staphylococcus aureus vaccines remains a significant challenge.
- Further research is needed to identify optimal antigens and strategies for Staphylococcus aureus prevention.
- Understanding the reasons for vaccine failure is crucial for future immunotherapeutic development.

01:29Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
01:26Antigens Involved in Adaptive Immunity
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.

01:25Clinical Significance of Antibiotic Resistance
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
01:31Defense Against Bacterial Pathogens
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

01:23Vaccine Production
Vaccine production involves a sequence of upstream and downstream processes to generate a safe and effective immunological product. It begins with cultivating microorganisms, such as viruses or bacteria, to obtain antigenic material. For viral vaccines, mammalian host cells are grown in bioreactors and subsequently infected with the target virus. The virus replicates within the host cells, which are lysed to release viral particles. This lysate is then clarified through filtration or...
