Cows phenomena medical8/7/2023 ![]() ![]() In adults, GBS can cause bacteremia, respiratory infections, urinary tract infections, joint and bone infections, endocarditis or meningitis, and skin and soft tissues infections, particularly in elderly and immunocompromised patients 11, 12. Despite the fact that GBS colonization may lead to neonatal infection, the predominant strains associated with carriage, notably sequence type (ST)1, ST19 and ST23, differ from the major neonatal clade, ST17 11. Furthermore, GBS is a severe neonatal infections such as sepsis, meningitis and pneumonia 10. In pregnant women, GBS may reach the amniotic fluid and fetal membranes, and cause fetal deaths 9. In South America, the reported prevalence of GBS colonization in pregnant women ranges from 6% to 26%, depending on country and culture methods 5, 6, 7, 8. GBS is often carried asymptomatically by healthy adults, ranging from 20 to 40% in developed countries 1, 2, 3, 4. Streptococcus agalactiae or Group B Streptococcus (GBS) is an important etiologic agent in a wide variety of human infections. Further investigation of this phenomenon is needed and could lead to modification of standard testing and treatment recommendations in human and veterinary medicine. Apparent prevalence of penicillin resistance was surprisingly high in human and bovine isolates. Two members of the bovine-specific clonal complex 61/67 were detected in human samples (ST718 and ST1175), providing evidence for the lack of genuine species barriers. Sequence type (ST) 1 was the most common strain in both host species, suggesting that interspecies transmission may be possible. The majority (64%) of isolates belonged to shared sequence types (ST). Across 33 farms, throat swabs and rectal swabs were collected from 191 people, and rectal swabs and composite milk samples from 2092 cattle, yielding 60 human isolates and 301 bovine isolates. We explored the potential transmission of GBS between cattle and people on dairy farms in Colombia and compared the antimicrobial resistance (AMR) profiles of isolates from both host species. ![]() The likelihood of GBS interspecies transmission is largely unknown. Additionally, GBS is a bovine pathogen causing intramammary infections. ![]() Group B Streptococcus (GBS), is a leading cause of neonatal death and an emerging pathogen in adults. ![]()
