AbstractBovine mastitis caused byStreptococcus agalactiaeis mainly subclinical and therefore can be diagnosed only in the laboratory. A nested polymerase chain reaction (PCR)-based method for specific, sensitive and rapid detection ofS. agalactiaein raw milk was developed. The general streptococci primers, which anneal to conserved areas within the 16S rRNA subunit gene, were used as positive controls. The specificity ofS. agalactiaeprimers is based on various areas within conserved areas of the 16S rRNA genes ofS. agalactiae. Results have indicated that the method enables the detection of 1 C

Abstract:

Contagious agalactia (CA) is one of the major animal health problems in small ruminants. It has economic effect and is caused by Mycoplasma agalactiae, the classic etiological agent in sheep and goats. The significance of the different Mycoplasma spp causing CA varies depending on the geographic area. This study conducted between 2012 and 2013 on 189 small ruminants with CA signs in the west of Iran, an area where CA is endemic. All samples (milk, synovial fluid, ear swabs, conjunctival swabs and nasal swabs) were examined by PCR method. Mycoplasma spp was detected in 76.2% and M. agalactiae

Abstract:

Contagious agalactia (CA) is suspected when small ruminants show all or several of the following clinical signs: mastitis, arthritis, keratoconjunctivitis and occasionally abortion. It is confirmed following mycoplasma isolation or detection. The historical and major cause is Mycoplasma agalactiae which was first isolated from sheep in 1923. Over the last thirty years, three other mycoplasmas (Mycoplasma mycoides subsp. capri, Mycoplasma capricolum subsp. capricolum and Mycoplasma putrefaciens) have been added to the etiology of CA because they can occasionally cause clinically similar outcome

ABSTRACT We developed a new recombinant enzyme-linked immunosorbent assay (rELISA) for serodiagnosis of contagious agalactia (CA), a disease caused by Mycoplasma agalactiae in sheep and goats. The assay is based on two M. agalactiae surface proteins, namely, P80 and P55. Identification of these immunodominant and common antigens was accomplished by examining the antibody response elicited in sheep during experimental infection and comparing it to the protein expression profiles of 75 M. agalactiae field strains.

To satisfy its growth requirements, S. agalactiae takes up 9 of the 20 proteinogenic amino acids from the environment. Defined S. agalactiae mutants in one or several of four putative peptide permease systems were constructed and tested for peptide uptake, growth in various media, and expression of virulence traits. Oligopeptide uptake by S. agalactiae was shown to be mediated by the ABC transporter OppA1-F, which possesses two substrate-binding proteins (OppA1 and OppA2) with overlapping substrate spe

The aim of this work was to evaluate the effects of beneficial human vaginal lactobacilli (Lb) on urogenital pathogens through in vitro and in vivo experiments. Co-aggregative and antimicrobial properties between five vaginal Lb strains and urogenital pathogens or potential pathogens (Streptococcus agalactiae, Staphylococcus aureus and Candida albicans strains) were assayed. Also, associative cultures of Lb strains and S. agalactiae were performed and bacterial growth, pH, lactic acid and hydrogen peroxide (H2O2) were determined at different times. Based on the results obtained, the in vivo st

Abstract:

SUMMARY Streptococcus agalactiae (group B Streptococcus) is the major cause of invasive bacterial disease, including meningitis, in the neonatal period. Although prophylactic measures have contributed to a substantial reduction in the number of infections, development of a vaccine remains an important goal. While much work in this field has focused on the S. agalactiae polysaccharide capsule, which is an important virulence factor that elicits protective immunity, surface proteins have received increasing attention as potential virulence factors and vaccine components. Here, we summarize curre

Abstract:

The phylogenically related Mycoplasma agalactiae and Mycoplasma bovis species are two ruminant pathogens difficult to differentiate and for which a limited amount of sequence data are available. To assess the degree of genomic diversity existing between and within these mycoplasma species, sets of DNA fragments specific for M. bovis type-strain PG45 or for M. agalactiae type-strain PG2 were isolated by suppression subtractive hybridization and used as probes on a panel of M. agalactiae and M. bovis field isolates. Results indicated that approximately 70 % of the DNA fragments specific to one o

Serologic diagnosis of ovine contagious agalactia ( Mycoplasma agalactiae) with the enzyme-linked immunosorbent assay (ELISA) developed by Agence Française de Séceurité Sanitaire des Aliments (AFS-SA) may produce a few false-positive (FP) and false-negative (FN) results. When the prevalence of disease is low, these erroneous results may generate problems for eradication schemes. To prevent this, 2 commercial ELISAs were compared with the AFSSA ELISA.

Abstract:

Streptococcus agalactiae is an important cause of invasive infections in neonates and is emerging as an important pathogen in elderly females. S. agalactiae is a commensal organism of the female genital tract; however, isolation from the uterine cavity suggests ascending infection of this organism caused by occlusion of the uterine cavity. We report a case of S. agalactiae causing pyometra in an elderly female with cervical cancer.

In zebrafish, NOD1 deficiency significantly promoted S. agalactiae proliferation and decreased larval survival. Transcriptome analysis revealed that the significantly enriched pathways in NOD1−/− adult zebrafish were mainly involved in immune and metabolism. Among 719 immunity-associated DEGs at 48 hpi, 74 DEGs regulated by NOD1 deficiency were histone variants. Weighted gene co

Abstract:

The genetic relationship between Streptococcus agalactiae and Streptococcus difficilis was studied. S. difficilis was originally described as serologically non-typable but was later reported to be a group B, type Ib streptococcus. Upon comparative analysis of five gene sequences, it was found that S. agalactiae and S. difficilis are closely related. Sequence similarity values between these two species were 100·0 % for 16S rRNA, 99·6 % for gyrB, 98·6 % for sodA, 99·5 % for gyrA and 99·8 % for parC genes. These data strongly suggest that S. agalactiae and S. difficilis are synonyms. The biochemi
