Chlamydia trachomatis is a major cause of ocular and sexually transmitted diseases worldwide. While much of our knowledge about its genetic diversity comes from serotyping or ompA genotyping, no quantitative assessment of genetic diversity within serotypes has been performed. To accomplish this, 507 urogenital samples from a multicenter U.S. study were analyzed by phylogenetic and statistical m...

Editor Striae are common dermal lesions of unknown aetiology. These stretch marks are linear and atrophic plaques due to the continuous and progressive distension of the skin. Their pathogenesis involves reductions and modifications in the configuration of the elastic fibres, collagen and fibrillin of the dermis, structures which are produced by fibroblasts. Striae and dystopic urogenital tissu...

Cholesterol determinations in morning urine samples were taken in 235 selected patients with a positive test for microscopic hematuria. Values ranged from 0.2 to 76.0 mg (median 5.5) in 23 patients with urologic malignancies and from 0.1 to 33.4 mg (median 1.1) in 38 patients with various benign diseases of the kidney or urogenital tract. In the 28 patients with urinary tract infections and 146...

Emergence of chronic inflammation in the urogenital tract induced by Chlamydia trachomatis infection in females is a long-standing concern. To avoid the severe sequelae of C. trachomatis infection, such as pelvic inflammatory diseases (PID), ectopic pregnancies, and tubal infertility, antibiotic strategies aim to eradicate the pathogen even in asymptomatic and uncomplicated infections. Although...

The morphology of the urogenital system of extant dipnoans is compared among the three genera, and to that of other fishes and amphibians. Analysis is based on dissections, sectioned material, and the literature. Urogenital system morphology provides no support for the hypothesis of a sister-group relationship between dipnoans and amphibians, for virtually all shared characters are primitive, a...

Diffusion-weighted magnetic resonance imaging (DW-MRI) appears to hold promise as a non-invasive imaging modality in the detection of early microstructural and functional changes of different organs. DW-MRI is an imaging technique with a high sensitivity for the detection of a large variety of diseases in the urogenital tract. In kidneys, DW-MRI has shown promise for the characterization of sol...

BACKGROUND Rosacea is a common chronic inflammatory dermatosis of unclear origin. It has been associated with systemic comorbidities, but methodical studies addressing this association are lacking. OBJECTIVE We evaluated: (1) the association between rosacea and systemic comorbidities; and (2) if the severity of rosacea is impacted by comorbidities. METHODS This was a case-control study: pat...

BACKGROUND Mycoplasma hominis and Ureaplasma urealyticum are implicated in a wide array of infectious diseases in adults and children. Since some species have innate or acquired resistance to certain types of antibiotics, antibiotic susceptibility testing of mycoplasma isolated from the urogenital tract assumes increasing importance. AIMS To evaluate the prevalence and antibiotic susceptibili...

I investigated the microanatomy of distal urogenital system male Wood Frog (Lithobates sylvaticus) from a small sample (n = 6) collected in northern Arkansas February 2020. Specifically, my primary objectives were as follows: 1) to focus on histology paired Wolffian (urogenital) ducts caudally kidneys their merging with urodeum cloaca, 2) reveal structure seminal vesicles (sperm storage structu...

Bacterial adherence and the growth of bacteria on solid surfaces as biofilm are both naturally occurring phenomena. Biofilms can be defined as an accumulation of microorganisms and their extracellular products forming structured communities attached to a surface. Biofilms are able to build up under natural circumstances, for instance on the urothelium or prostate stones and they can also coloni...
