Abstract
BACKGROUND Inflammatory diseases may occur within the crypt beside the preputial frenulum in men. This study was performed to gain an understanding of the etiology, clinical manifestations, and management methods of cryptitis beside the preputial frenulum in men. RESULTS Thirteen patients treated for cryptitis beside the preputial frenulum served as the observation group, and 40 healthy individuals served as the control group. The patients' clinical manifestation was the presence of a yellowish oily substance embedded in the crypt. Wiping off the substance revealed a conical blind cavity-like structure with an opening diameter of 1 to 5 mm (2.8 ± 1.3 mm) and depth of 1 to 4 mm (2.5 ± 1.1 mm). No blind cavity-like structures in the crypt were found in the control group. The shortest distance between the opening edges of the bilateral crypts in the observation and control groups was 6 to 14 mm (10.3 ± 2.4 mm) and 2 to 10 mm (3.9 ± 1.9 mm), respectively, with a statistically significant difference. Examination for pathogens in the secretions from skin lesions showed that the three most common pathogens were Candida albicans, Staphylococcus aureus, and Escherichia coli. All patients recovered after antibiotic treatment. CONCLUSIONS A blind cavity-like structure in the crypt may be related to excessive width of the preputial frenulum. Cryptitis may be a secondary infection caused by smegma trapped in the blind cavity-like structure. Maintaining cleanliness in the frenulum area may help to prevent the occurrence of cryptitis. Antibiotic treatment is effective.

Abstract
The penile epithelial microbiome remains underexplored. We sequenced human RNA and a segment of the bacterial 16S rRNA gene from the foreskin tissue of 144 adolescents from South Africa and Uganda collected during penile circumcision after receipt of 1-2 doses of placebo, emtricitabine + tenofovir disoproxil fumarate, or emtricitabine + tenofovir alafenamide to investigate the microbiome of foreskin tissue and its potential changes with antiretroviral use. We identified a large number of anaerobic species, including Corynebacterium acnes, which was detected more frequently in participants from South Africa than Uganda. Bacterial populations did not differ by treatment received, and no differentially abundant taxa were identified between placebo versus active drug recipients. The relative abundance of specific bacterial taxa was negatively correlated with expression of genes downstream of the innate immune response to bacteria and regulation of inflammation. Our results show no difference in the tissue microbiome of the foreskin with short-course antiretroviral use but that bacterial taxa were largely inversely correlated with inflammatory gene expression, consistent with commensal colonization.

Abstract
Introduction Balanitis is an inflammation of the glans penis. Balanoposthitis involves both the glans penis and prepuce and occurs only in uncircumcised males. Recurrent balanoposthitis represents a strong indication for circumcision. After Candida infections, aerobic bacteria are the second most common aetiological cause of acute infectious balanoposthitis, mainly streptococci groups B and D, and staphylococci, usually S. aureus . Their clinical manifestations are variable inflammatory changes, including diffuse erythema and oedema. Severe balanopreputial oedema with purulent exudate occurs in painful, erosive streptococcal balanoposthitis. Coagulase-negative staphylococci (CoNS) are commensal skin bacteria, but are also recognized pathogens of the genitourinary system, mainly related to urinary tract infections. Staphylococcus haemolyticus is one of the main species of CoNS that is part of the cutaneous microflora but is also associated with nosocomial infections. In addition, S. haemolyticus also causes other infections of the male urogenital tract, such as chronic prostatitis and epididymo-orchitis, but it has not been associated with balanitis. Case presentation A 45-year-old man reports having suffered several episodes of balanoposthitis in the last 3 years, which were treated with topical antifungal treatments alone or associated with corticosteroids. For this reason, he underwent a postectomy by his urologist 8 months ago to avoid further recurrences. The patient consulted for an episode of painful, erosive and exudative lesions on the glans penis and over the post-operative scars lasting 5 days. He had no urinary discomfort or inguinal lymphadenopathy. A complete blood count, biochemical analysis, C-reactive protein (CRP), prostate-specific antigen (PSA) and urinalysis were normal. Abundant growth of S. haemolyticus was obtained in the culture on tryptone soya agar with sheep blood and chocolate agar with Vitox media. The MicroScan panel CIM 37 (PM37) was used to study the antimicrobial susceptibilities of the isolated bacteria. The fungal culture on Sabouraud dextrose agar was negative. Based on the antimicrobial susceptibility study, treatment with oral ciprofloxacin and topical mupirocin was started, and the genital infection was completely cured. Conclusion We present a healthy, non-diabetic, circumcised male patient with severe, erosive and painful balanitis probably due to S. haemolyticus .

Abstract
The human body represents a complex and diverse reservoir of microorganisms. Although the human microbiome remains poorly characterized and understood, it should not be underestimated, since recent studies have highlighted its importance in health. This is especially evident when considering microbiota in the male reproductive system, responsible for men’s fertility and sexual behavior. Therefore, the aim of this systematic review is to provide an overview of the microbial communities of the healthy male genital mucosa and its role in disease. This study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The search was limited to the English language and studies published until August 2022 that included culture-independent techniques for microbiome characterization in male genital mucosa. Ten articles were included. The bacterial composition of the male genital mucosa consists of several genera including Prevotella, Finegoldia, Peptoniphilus, Staphylococcus, Corynebacterium, and Anaerococcus, suggesting that the male genital microbiome composition shows similarities with the adjacent anatomical sites and is related with sexual intercourse. Moreover, male circumcision appears to influence the penile microbiome. Despite the lack of knowledge on the male genital mucosa microbiome in disease, it was reported that Staphylococcus warneri and Prevotella bivia were associated with balanoposthitis, whereas Enterobacteriaceae, Prevotella, and Fusobacterium were more abundant in male genital lichen sclerosus. The limited data and paucity of prospective controlled studies highlight the need for additional studies and established criteria for sampling methods and the microbiome assay procedure. Such a consensus would foster the knowledge about the composition of the genital microbiome of healthy males and its role in disease.

Abstract
The skin is the largest and outermost organ of the human body. The microbial diversity of the skin can be influenced by several variable factors such as physiological state, lifestyle, and geographical locations. Recent years have seen increased interest in research aiming at an improved understanding of the relationship between the human microbiota and several diseases. Albeit understudied, interesting correlations between the skin microbiota and several dermatological conditions have been observed. Studies have shown that a decrease or increase in the abundance of certain microbial communities can be implicated in several dermatological pathologies. This narrative review (i) examines the role of the skin microbiota in the maintenance of skin homeostasis and health, (ii) provides examples on how some common skin diseases (acne inversa, candidiasis, psoriasis) are associated with the dysbiosis of microbial communities, and (iii) describes how recent research approaches used in skin microbiome studies may lead to improved, more sensitive diagnostics and individual therapeutics in the foreseeable future.

Abstract
Mycoplasma species (spp.) are bacteria that are difficult to detect. Currently, the polymerase chain reaction (PCR) is considered the most effective diagnostic tool to detect these microorganisms in both human and veterinary medicine. There are 13 known species of human Mycoplasma and 15 species of canine Mycoplasma. Owing to the difficulties in identifying the individual species of Mycoplasma, there is a lack of information regarding which species are saprophytic and which are pathogenic. The prevalence of the individual species is also unknown. In addition, in both humans and dogs, the results of some studies on the impact of Mycoplasma are conflicting. The presence of Mycoplasma spp. on the epithelium of reproductive tract is often associated with infertility, although they are also detected in healthy individuals. The occurrence of Mycoplasma spp. is more common in dogs (even 89%) than in humans (1.3%-4%). This is probably because the pH of a dog's genital is more conducive to the growth of Mycoplasma spp. than that of humans. Phylogenetically, human and canine Mycoplasma are related, and majority of them belong to the same taxonomic group. Furthermore, 40% of canine Mycoplasma spp. are placed in common clusters with those of human. This suggests that species from the same cluster can play a similar role in the canine and human reproductive tracts. This review summarizes the current state of knowledge about the impact of Mycoplasma on canine and human male fertility as well as the prospects of further development in this field.
