ABSTRACT

Partial or complete bladder eversion is a rare condition of poor prognosis in cows, commonly associated with intense tenesmus observed in the peripartum period. A 14-year-old obese Nellore cow at 280 days of gestation was referred with 24-hour bladder prolapse. The bladder was complete eversion through the vulvar vestibule showing a thick congested wall and small residual urine volume. After clinical examination, the cow received scopolamine butylbromide and intercoccygeal epidural anesthesia, and the externalized bladder segment was partially reduced, remaining only 10 cm externalized. The cow was maintained with an intravesical human gastric tube number 16 and constant monitoring. The eversion was fully reduced after 12 hours of local treatment, and as the cow presented subclinical ketosis, hypocalcemia and cystitis, antibiotic, glucose, calcium and propylene glycol therapy were performed. We opted for induction of parturition, and after 24 hours, a healthy 52kg calf was born and the placenta was delivered 16 hours after calving. The cow and calf were discharged on the sixth day of hospitalization, with no recurrences or secondary complications after treatment.


A eversão vesical parcial ou completa é uma condição rara de mau prognóstico em vacas, comumente associada a tenesmo intenso observado no período periparto. Uma vaca Nelore obesa de 14 anos de idade, com 280 dias de gestação, foi encaminhada com prolapso de bexiga de 24 horas. A bexiga apresentava eversão completa por meio do vestíbulo vulvar apresentando parede espessa e congestionada e pequeno volume residual de urina. Após exame clínico, a vaca recebeu butilbrometo de escopolamina e anestesia peridural intercoccígea, e o segmento vesical exteriorizado foi parcialmente reduzido, permanecendo apenas 10cm exteriorizado. A vaca foi mantida com sonda gástrica humana número 16 por via intravesical e monitorada constantemente. A eversão foi totalmente reduzida após 12 horas de tratamento local, e, como a vaca apresentava cetose subclínica, hipocalcemia e cistite, foi realizada antibioticoterapia, glicose, cálcio e propilenoglicol. Optou-se pela indução do parto. Após 24 horas, nasceu um bezerro saudável de 52kg e a placenta foi expelida 16 horas após o parto. A vaca e o bezerro receberam alta no sexto dia de internação, sem recidivas ou complicações secundárias após o tratamento.

ABSTRACT

In recent years, veterinary probiotic formulations constitute an interesting alternative to the use of antibiotics in animals for human consumption, but beneficial microorganisms must meet certain requirements to be included in these products. The objective of this work was to evaluate the safety and innocuity of beneficial autochthonous lactic bacteria (BALB) as well as to determine their beneficial, environmental, and technological characterization. Antibiotic resistance was assayed using phenotypic and genotypic methodology. A bovine vaginal fluid simulated medium (MSBVF) was designed where growth, pH changes, and expression of beneficial characteristics of lactic bacteria were evaluated; additionally, the optimal culture conditions in commercial media were determined in order to obtain the highest biomass production of the strains. Finally, the best strains were lyophilized and administered intravaginally to pregnant cows and their permanence in the vagina and adverse effects were evaluated. The results show that most of the strains were resistant to vancomycin, tetracycline, and streptomycin, with a high sensitivity to ampicillin, gentamicin, and clindamycin. The strains evaluated did not show gelatinase or hyaluronidase activity; however, 11 strains produced α-type hemolysis. The optimal growth of the microorganism was obtained in MRS broth, under slight agitation and without pH control. The strains grown in the MSBVF grew well and maintained the probiotic properties. Animals treated with probiotics bacteria did not show systemic or local inflammation. These strains can be included in a probiotic veterinary product to be applied to different bovine mucosa.
