“…Transmission through sexual contact has been reported for H. influenzae [ 7 ], including unprotected oral sex [ 3 , 7 , 8 , 9 ]. Our patient had protected coitus but unprotected orogenital sex, which suggests transmission of the oropharyngeal commensal flora from his partner, who was likely colonized by H. influenzae , to the urethra, allowing the bacteria to express their virulence factors, mainly adhesins and pili, responsible for adhesion to the genital epithelium.…”

Urethritis may be acute or subacute and can be classified as gonococcal or nongonococcal. Nongonococcal urethritis is mainly dominated by Chlamydia trachomatis . Other bacteria such as Haemophilus influenzae have been implicated in some cases. We report the case of a 56-year-old diabetic man with H. influenzae urethritis following unprotected oral sex. The patient initially received treatment with ciprofloxacin, but this proved to be ineffective. Once our diagnosis was made, we switched the patient to cefixime for a period of seven days, which resulted in a successful clinical outcome.

“…Clinically, common symptoms of Haemophilus spp. urethritis include urethral discomfort, dysuria, and/or mucopurulent or clear discharge [ 7 ]. Our patient’s symptoms were consistent with this clinical presentation, exhibiting all of the previously mentioned clinical elements as well as a clear discharge.…”

The impact of urine collection method on canine urinary microbiota detection: a cross-sectional study

Background The urinary tract harbors unique microbial communities that play important roles in urogenital health and disease. Dogs naturally suffer from several of the same urological disorders as humans (e.g., urinary tract infections, neoplasia, urolithiasis) and represent a valuable translational model for studying the role of urinary microbiota in various disease states. Urine collection technique represents a critical component of urinary microbiota research study design. However, the impact of collection method on the characterization of the canine urinary microbiota remains unknown. Therefore, the objective of this study was to determine whether urine collection technique alters the microbial populations detected in canine urine samples. Urine was collected from asymptomatic dogs by both cystocentesis and midstream voiding. Microbial DNA was isolated from each sample and submitted for amplicon sequencing of the V4 region of the bacterial 16 S rRNA gene, followed by analyses to compare microbial diversity and composition between urine collection techniques. Results Samples collected via midstream voiding exhibited significantly higher sequence read counts (P = .036) and observed richness (P = .0024) than cystocentesis urine. Bray Curtis and Unweighted UniFrac measures of beta diversity showed distinct differences in microbial composition by collection method (P = .0050, R2 = 0.06 and P = .010, R2 = 0.07, respectively). Seven taxa were identified as differentially abundant between groups. Pasteurellaceae, Haemophilus, Friedmanniella, two variants of Streptococcus, and Fusobacterium were over-represented in voided urine, while a greater abundance of Burkholderia-Caballeronia-Paraburkholderia characterized cystocentesis samples. Analyses were performed at five thresholds for minimum sequence depth and using three data normalization strategies to validate results; patterns of alpha and beta diversity remained consistent regardless of minimum read count requirements or normalization method. Conclusion Microbial composition differs in canine urine samples collected via cystocentesis as compared to those collected via midstream voiding. Future researchers should select a single urine collection method based on the biological question of interest when designing canine urinary microbiota studies. Additionally, the authors suggest caution when interpreting results across studies that did not utilize identical urine collection methods.
