Potential risk factors for Ureaplasma diversum in the vaginal mucus of 1,238 dairy cows were included in a multivariate logistic regression model, based on the cow level (i.e., granular vulvovaginitis [+GVV], yearly milk production [4500 kg or more], pregnancy, predominance of Bos taurus [+Bos Taurus], score of corporal condition [at least 2.5], concomitant positivity for Escherichia coli [+E.c...

The activity of grepafloxacin, a new orally active fluoroquinolone, was compared with the activities of ofloxacin, clarithromycin and doxycycline against Chlamydia pneumoniae, Chlamydia trachomatis, Mycoplasma pneumoniae, Mycoplasma hominis and Ureaplasma urealyticum, and with the activities of ofloxacin, clarithromycin and rifampicin against Legionella spp. Grepafloxacin (MIC range 0.06-0.12 m...

Mastitis is one of the main diseases that affects dairy cattle. It characterized by a multifactorial disease with multiple etiologies including microorganisms such as bacteria, viruses, fungi, yeasts, and algae. caused Mycoplasma spp. results in contagious nature infection has been studied much Brazil. The objectives this research were (1) to investigate clinical mastitis milk samples, conventi...

Preterm delivery (PTD) is the leading cause of infant morbidity and mortality. Epidemiological association between PTD and various bacteria that are part of the vaginal microflora has been reported. Bacterial vaginosis is believed to be a risk factor for preterm delivery. The aim of the present study is to investigate the association between bacterial vaginosis, cervicovaginal fetal fibronectin...

Mycoplasma spp, belongs to the class Mollicutes and is capable to produce alterations in cellular cultures causing damages to the biotechnological industry. Bioproducts generally require two essential inputs, bovine serum and cells. The study herein aims to evaluate the mycoplasma concentrations that affect the growing of BHK21 and Vero cells. The species used were: Mycoplasma orale, M. salivar...

The present study was carried out to determine the prevalence of subclinical mastitis in cattle in eighteen herds in the center region of Algeria. Milk samples were collected from 560 quarters of 140 cows free of clinical mastitis. The samples were subjected to California Mastitis Test (CMT) and the positive samples were analysed by bacteriological culture and Speed Mam® Color. The overall quar...

Bacterial and Fungal Organisms in the Vagina of Normal Cows and Cows with Vaginitis. (December 2003) James Ross Husted, B.S. Texas A&M University Chair of Advisory Committee: Dr. R. Bruce Simpson Previous studies on infections of the reproductive tract in various animal species have focused on uterine and cervical infections. This study defined the bacterial flora from the vaginal fornix of 110...

The study evaluated possible transmission of Mycoplasma bovis from sand bedding to naive dairy calves. Screening of a closed herd showed 99% probability that the herd was free of mycoplasma in calves. Neonatal calves (n = 12) from the herd were blocked by weight and height and randomly assigned as controls (n = 6) bedded with quarry sand, or exposed (n = 6) bedded with M. bovis-positive bedding...

BACKGROUND Detection of Ureaplasma, Mycoplasma and Candida spp. in the vagina during pregnancy has previously been associated with preterm birth (PTB). However, the prevalence of these microorganisms and the associated obstetric risks (likely to be population-specific) have not been determined in Australian women; furthermore, in the case of Ureaplasma spp., very few studies have attempted char...
