Vaginal microbiota in Pelibuey sheep treated with antimicrobials at the removal of intravaginal sponges impregnated with flurogestone acetate

Comparison of the Efficacy of Enrofloxacin and Lactobacillus Plantarum Cell-Free Supernatant Treatments on Vaginitis in Ewes

“…7 Therefore, vaginitis after using intravaginal sponges leads to the reduction of pregnancy rate. 8 Vaginal bacterial load number increases with vaginitis at sponge removal compared to sponge insertion in ewes. 2 Escherichia coli, Staphylococcus spp., and Trueperella spp.…”

“…constitutes the majority of the vaginal microbiota in ewes with vaginitis. 5,[8][9][10][11][12][13] Efficient antibiotic therapy such as enrofloxacin was recommended to reduce the detrimental effects of vaginitis in recent studies. 8 However, controlling vaginitis by adding antibiotics into sponge has not been preferred due to the resistance of microorganisms 8,14 and drug residues.…”

“…5,[8][9][10][11][12][13] Efficient antibiotic therapy such as enrofloxacin was recommended to reduce the detrimental effects of vaginitis in recent studies. 8 However, controlling vaginitis by adding antibiotics into sponge has not been preferred due to the resistance of microorganisms 8,14 and drug residues. 15,16 Considering the resistance of microorganisms to antibiotics and residue for human health, antibiotic-free treatment options should be investigated.…”

Use of Probiotics in Intravaginal Sponges in Sheep: A Pilot Study

“…The use of intravaginal devices may generate retention of vaginal secretions and abnormal discharges at device withdrawal, which may create changes in the normal vaginal bacterial microbiota [3,4] and a lower fertilization rate [5][6][7][8]. These changes in vaginal microbiota could allow the growth of opportunistic pathogenic bacteria which can require antibiotic treatment [9,10]. The addition of antibiotics on sponges poses a risk of antibiotic residues presence in small ruminants milk [11].…”

Los dispositivos reutilizados en protocolos cortos de sincronización tienen el mismo efecto sobre el desempeño reproductivo y perfiles de progesterona en ovejas Pelibuey

“…El tratamiento hormonal más usado en protocolos de sincronización del estro en ovinos son los basados en el uso de progesterona natural (P4) y progestágenos (Abecia et al, 2011) administrados a través de dispositivos intravaginales (silicona o esponjas de poliuretano). La sincronización del estro con esponjas en ovejas es menos costoso, sin embargo, se reportan mayores casos de vaginitis y cambios en la flora vaginal (Manes et al, 2018;Ojeda-Hernández et al, 2019) lo cual puede afectar negativamente la atracción sexual de la oveja (Gatti y Ungerfeld, 2012).…”
