Background: Due to its distinct vascular tropism, Campylobacter fetus is recognized as a significant cause of severe systemic infections, especially in immunocompromised individuals, while it is rarely reported as a cause of gastrointestinal infections. Methods: A rare case of mycotic abdominal aortic aneurysm associated with Campylobacter fetus detected on the aneurysm wall itself was described. Results: A 68-year-old male was admitted to the hospital due to severe abdominal pain. The patient was afebrile, hemodynamically stable with elevated C-reactive protein levels. A physical examination revealed a palpable, pulsatile, tender mass located in the periumbilical region. Ultrasonography and multi-slice computer tomography angiography (MSCTA) identified an infrarenal abdominal aortic aneurysm with a maximum diameter of 6.5 cm, showing suspicious signs of dissection. Aneurysmectomy with Dacron tube graft interposition was performed. Although the blood cultures remained negative, the culture of the aneurysmal wall grew Campylobacter fetus, enabling early diagnosis and targeted antibiotic therapy. The patient was treated with meropenem for two weeks, followed by amoxicillin-clavulanate for another two weeks after hospital discharge. Conclusions: Campylobacter fetus associated with abdominal aortic aneurysms represents a life-threatening condition, posing a significant challenge in vascular surgery. Due to the lack of clear guidelines on antibiotic susceptibility testing and the treatment of infections associated with this pathogen, enhanced surveillance of Campylobacter fetus is necessary in both human and veterinary medicine.

Human papillomavirus (HPV) is one of the most common sexually transmitted infections, affecting both men and women. However, in Serbia, the previous epidemiological and clinical research on HPV has primarily focused on women due to its established role in cervical cancer, while the data on HPV prevalence in men remain scarce. This study analyzed 634 samples from men (mean age: 30 years, SD = 9.98; range: 18–79) from between 2012 and 2024. Overall, 30.76% of the tested men were HPV–positive, with the highest percentage of cases being observed in those aged 25–29 years (32.82%). The most common genotypes were HPV 16 and HPV 31 (22.05% each), followed by HPV6 (20.51%), HPV 56, and HPV 52 (9.23% each). The prevalence of HPV was the highest in the samples from men with genital warts (40.77%). Among the available vaccines, the nonavalent Gardasil 9 provides the broadest protection, covering genotypes found in 82% of the HPV–positive cases identified in this study. Our findings underscore the importance of comprehensive HPV prevention and control measures for the male population, contributing to ongoing research efforts aimed at reducing the burden of HPV–associated diseases in our region. Increasing the vaccination coverage among Serbian men could substantially reduce the overall burden of HPV–related diseases in both sexes.
