Abstract:
People with diabetes are at increased risk of infection and are worried about biological agents such as bacteria. Particularly, foot infections, urinary tract infections, pneumonia, and skin diseases are due to bacterial infections that make diabetic patients suffer from clinical difficulties. Although antibiotics, one of the bacterial therapies, have been used, the emergence of multidrug-resistant bacteria is now in demand for alternative therapies. Although, many studies reported that antibiotic-resistant for bacterial infections and their rate have increased significantly in the diabetic pa

Skin and wound infections are serious medical problems, and the diversity of bacteria makes such infections difficult to treat. Bacteria possess many virulence factors, among which motility plays a key role in skin infections. This feature allows for movement over the skin surface and relocation into the wound. The aim of this paper is to review the type of bacterial movement and to indicate the underlying mechanisms than can serve as a target for developing or modifying antibacterial therapies applied in wound infection treatment.

Bacterial infections can be of two types: acute or chronic. The chronic bacterial infections are characterized by being a large bacterial infection and/or an infection where the bacteria grows rapidly.

The microabscess is characterized by an area comprising fluids, bacteria, immune cells (mainly neutrophils), and many types of dead cells.

Abstract:
Bacteria causing chronic infections are generally observed living in cell aggregates suspended in polymer-rich host secretions, and bacterial phenotypes induced by aggregated growth may be key factors in chronic infection pathogenesis. Bacterial aggregation is commonly thought of as a consequence of biofilm formation; however the mechanisms producing aggregation in vivo remain unclear. Here we show that polymers that are abundant at chronic infection sites cause bacteria to aggregate by the depletion aggregation mechanism, which does not require biofilm formation functions.

Bacteroides caccae is an anaerobic bacterium with a reportedly high isolation rate; however, it rarely causes bloodstream infections. Patients with hypertension are at increased risk of developing anaerobic bacterial infection.

This study describes the clinical manifestations of bloodstream infection involving B. caccae to provide guidance for laboratory technicians and clinicians.

Abstract:
Endodontic infection is a penetration of microorganisms into the dental pulp. Bacteria are the most common entities that induce an infection. This state is associated with significant pain and discomfort. Therapeutic intervention involves removal of infected pulp from the tooth and roots, which eliminates viable tissue, thus creating a tooth less resistant to mechanical pressure. Studies suggest that there are several types of bacteria most commonly associated with endodontic infections. Furthermore, it is considered that different types of pathogens could play a major role in primary and seco

Urinary tract infection is the global health problem being 2nd most common bacterial infection. The abuse of antibiotics without bacterial characterization during its treatment results in emergence of highly antibiotic-resistant bacteria. Some biofilm forming bacterial strains are hard to treat using antibiotics. So, an alternative therapy is urgently needed. Phage therapy offers promising results for treatment of these infections in which virulent or lytic phages are used to lyse infection-causing bacterial cells.

Optical imaging of bacteria in vivo is much less developed than methods such as radioimaging and MRI. Furthermore near-infrared (NIR) dyes with emission wavelengths in the region of 650–9
