Adhesins need to be exposed on the surface of pathogenic bacteria to properly interact with host tissues and allow establishment of the infection. This fact implies that, in theory, one could manage or avoid infection by controlling adhesins' function, and also by indirectly detecting bacteria through their surface-exposed adhesins. Besides, binding of anti-adhesin immunoglobulins on the bacterial surface tend to promote the opsonization of the pathogen. Therefore, bacterial adhesins represent a great target to develop new biopharmaceuticals, which may become commercially and medically important products. In this review, we will summarize the biological importance of bacterial adhesins, and also discuss some recent patents related to these molecules, as well as their use and possible new future developments in this area.

Urinary tract infections (UTIs) are among the most common bacterial infections of both dogs and humans, with most caused by uropathogenic Escherichia coli (UPEC). Recurrent UPEC infections are a major concern in the treatment and management of UTIs in both species. In humans, the ability of UPECs to form intracellular bacterial communities (IBCs) within urothelial cells has been implicated in recurrent UTIs.

Combating multidrug-resistant is considered a priority by the World Health Organization. Virulence mechanisms, such as biofilm formation, multidrug resistance, and high adherence to both biotic and abiotic surfaces, underscore the urgency of exploring approaches to control this pathogen. The search for new antibiotic compounds and alternative strategies like immunotherapies and vaccination offers potential solutions to address this pressing health concern.
