Background: The vaginal microbiota consists primarily of Lactobacillus species, which help maintain microbial balance through acid production and antimicrobial activity. The disruption of balance causes vaginal dysbiosis and infection. Objective: The aim of this study was to analyze the association of vaginal infection with the distribution of Lactobacillus species, vaginal pH, and antimicrobial activity. Methods: The study was designed as a case-control study. A total of 100 subjects, including 50 healthy subjects and 50 infected subjects, were included. Vaginal swabs were collected to assess pH, microbial isolation, and identification using the standard microbiology technique. The antimicrobial activity of Lactobacillus isolates was assessed using the agar well diffusion technique and peroxide production was assessed qualitatively. Chi-square test and independent t-test were used for the statistical analysis of the results. Results: The isolation of Lactobacillus was 90% in healthy women and 40% in infected women, with a statistically significant difference (p < 0.001). Infected women had increased vaginal pH (5.6 ± 0.5) as compared to healthy women (4.3 ± 0.3) (p < 0.001). Lactobacillus crispatus was the most frequent in healthy women and Lactobacillus iners was the most frequent in infected women. Pathogenic organisms, especially Gardnerella vaginalis, were statistically significantly more common in the infected group. The isolates taken from healthy women had the highest hydrogen peroxide production and antimicrobial activity. Conclusions: An increase in vaginal pH, a decrease in antimicrobial defenses, and overgrowth of pathogens are associated with the loss of functionally active Lactobacillus species. Composition and functional capacity are critical factors in determining vaginal health.

The vertebral column begins at the occipital bone and concludes with the coccyx, collectively forming the structure referred to as the Ṣulb, or spine. The vertebrae are relatively small in size and extend from the cervical region down to the coccyx, with the spinal cord being distinct from the brain. The cervical vertebrae are essential for facilitating a range of movements while maintaining stability, and their cavities are designed to be spacious, allowing the spinal cord to reside within them comfortably. The vertebrae have a distinctive thorn-like form, with each featuring two foramina located on its right and left sides. From each foramen, two processes extend; one connects to the upper vertebral foramen, while the other connects to the lower vertebral foramen. The closure of these foramina has enhanced stability and strength within the vertebral structure. Each vertebra is characterized by three analogous processes: one that extends upward and two that project laterally. A vertebra typically features four processes, with two located on the right and two on the left of the foramen. The processes serve the essential function of establishing articular connection between adjacent vertebrae, utilizing the cavities of some processes and the condyloid projections of others. They also provide protection, support, and resistance to impact, as well as facilitate the attachment of ligaments. The structures located at the posterior aspect of the vertebrae are referred to as spinous processes, while those situated laterally on the right and left are known as transverse processes. These processes serve to safeguard the nerves, blood vessels, and muscles that are situated deeper within the body along its length. The spinal cord's gradual reduction in thickness from top to bottom mirrors natural patterns found in rivers and trees, allowing for the emergence of nerve pairs from the intervertebral foramen. The cervical region comprises five cervical vertebrae, each characterized by four processes that extend both upward and downward. The twelve vertebrae of the spine are arranged such that each joint produces two upwardly extending processes, while two additional processes descend into corresponding pits that interlock with adjacent vertebrae. The research aims to conduct a comprehensive analysis of the complex anatomical framework of the vertebral column, as described by various esteemed scholars and notable philosophers from both Greek and Arab civilizations.
