Two strains of Trueperella (Arcanobacterium) pyogenes previously isolated from lung abscesses of two camels (Camelus dromedarius) in Jordan were identified phenotypically, by MALDI-TOF MS analysis and genotypically using T. (A.) pyogenes 16S-23S rDNA intergenic spacer region (ISR) and T. (A.) pyogenes superoxide dismutase A encoding gene sodA specific oligonucleotide primers. Both isolates coul...

Objective: Identify the occurrence of certain virulence genes Escherichia coli vaginal isolates associated with postpartum dysgalactia syndrome (PDS) in sows. Materials and methods: Two hundred two sows from 5 Macedonian pig farms were clinically examined for PDS 12 to 24 hours after farrowing. Vaginal swabs bacteriological testing taken PDS-affected (PDSA, n = 47) PDS-unaffected (PDSU, 155) In...

Due to the genetic similarity of pathogenic Escherichia coli isolated from birds and pathotypes human origin, it is suggested that they have a common ancestor may exchange virulence-associated genes. This study aimed detect genes in E. strains Red-browed Amazon parrot (Amazona rhodocorytha) kept at conservation institute Brazil. High variability virulence was observed, since 12 profiles were fo...

Porphyromonas gingivalis is a keystone periopathogen that plays an essential role in the progress of periodontitis. Like other gram-negative bacteria, the ability of P. gingivalis to produce outer membrane vesicles is a strategy used to interact with, and survive within its biological niches. Here we compared the protein components associated with vesicles derived from a fimbriated strain (3327...

The present study reports on layer chickens with colibacillosis in 2 commercial egg-producing farms (referred to as farm A and farm B, which were managed by the same owner and were about 1 km apart) in the middle region of the Korean peninsula. The 2 flocks were infected at the initiation of egg laying. They were characterized by no previous clinical signs but sudden mortality (2.7-4.0%), with ...

The assembly of type 1 pili on the surface of uropathogenic Escherichia coli proceeds via the chaperone-usher pathway. Chaperone-subunit complexes interact with one another via a process termed donor strand complementation whereby the G1beta strand of the chaperone completes the immunoglobulin (Ig) fold of the pilus subunit. Chaperone-subunit complexes are targeted to the usher, which forms a c...

Urinary tract infection (UTI) is a major bacterial infectious disease among women. Uropathogenic Escherichia coli is the most dominant causative agent. Clinical observations indicate that repeated cystitis induces a protective immune response and secretory IgA has been suggested as one of the candidates involved in the defence mechanisms against bladder infections. The aims of the present study...

The acquisition of transition metal ions is essential for the viability and in some cases the expression of virulence genes in bacteria. The fimCBA operon of Streptococcus parasanguinis FW213 encodes a Mn(2+)/Fe(2+)-specific ATP-binding cassette transporter. FimA, a lipoprotein in the system, is essential for the development of endocarditis, presumably by binding to fibrin monolayers on the dam...
