subsp. serovar Paratyphi B from mute swan (): complete genome sequence features point towards invasive variant potential.

A subgroup of Salmonella (S.) enterica subsp. enterica serovar Paratyphi B is significantly associated with invasive infections in humans.

gen. nov., sp. nov. a member of the family associated with bovine endocarditis.

Seven bacterial strains isolated from bovine endocarditis in six animals from different geographic regions were investigated in a polyphasic taxonomic approach. Phylogenetic analysis based on 16S rRNA gene sequences placed all seven isolates on a distinct, monophyletic cluster in the family with closest similarity to type strains of (97.06 %) and (96.

Re-Emergence and Spread of Haemorrhagic Septicaemia in Germany: The Wolf as a Vector?

Since 2010, outbreaks of haemorrhagic septicaemia (HS) caused by (.) capsular type B (B) emerged in Germany. In 2017, we noticed a close spatiotemporal relationship between HS outbreak sites and wolf () territories.

Reliable differentiation of a non-toxigenic tox gene-bearing Corynebacterium ulcerans variant frequently isolated from game animals using MALDI-TOF MS.

Corynebacterium (C.) ulcerans is a zoonotic member of the C. diphtheriae group and is known to cause abscesses in humans and several animal species.

Streptococcus castoreus, an uncommon group A Streptococcus in beavers.

Streptococcus castoreus is a rarely encountered beta-haemolytic group A Streptococcus with high tropism for the beaver as host. Based on 27 field isolates under study, evidence strongly suggests that S. castoreus behaves as an opportunistic pathogen in beavers.

Draft Genome Sequences of Helcococcus ovis Strains Isolated at Time of Metritis Diagnosis from the Uterus of Holstein Dairy Cows.

is an emerging pathogen implicated in the pathogenesis of metritis in dairy cows. Herein, we report the first draft genome sequences of four isolates from the uterus of dairy cows with metritis. This information will enable a better understanding of the bacterium's pathogenicity and antimicrobial resistance.

Isolation and antimicrobial susceptibility of Streptococcus castoreus isolated from carcasses of European beavers (Castor fiber) in Germany.

Streptococcus (S.) castoreus was isolated from seven beavers (Castor fiber), which were found dead in the federal state of Brandenburg, Germany, and submitted to the Berlin-Brandenburg State laboratory for post mortem diagnostics. The isolates originated from various inflammatory processes where they were associated with other Gram negative and Gram positive aerobic and/or anaerobic bacteria (i.

Nontoxigenic tox-bearing Corynebacterium ulcerans infection among game animals, Germany.

Corynebacterium ulcerans may cause diphtheria in humans and caseous lymphadenitis in animals. We isolated nontoxigenic tox-bearing C. ulcerans from 13 game animals in Germany.

Cryptosporidium baileyi--infection in Red-breasted Merganser (Mergus serrator) ducklings from a zoological garden.

Infection of the Bursa of Fabricius with Cryptosporidium baileyi was diagnosed in a group of hand reared Red-breasted Merganser (Mergus serrator) ducklings during one breeding season in a German zoological garden.The birds had died in an emaciated and anaemic state after problems with spontaneous feeding. The bursae were infected with moderate to high numbers of cryptosporidia, which were associated with hyperplasia, degeneration and sloughing of the affected epithelial cells and mild heterophilic bursitis, lesions typically seen in bursal cryptosporidiosis in other avian species.

[Acute pasteurellosis in fallow deer, cattle and pigs in a region of Eastern Germany].

Hemorrhagic septicaemia, an acute disease caused by P multocida capsular type B which is rarely detected in Europe, caused considerable losses in fallow deer, cattle and pigs within a region along the border of the federal states Brandenburg and Saxony-Anhalt in the summer of 2010. Clinical appearances and diagnostic findings are presented and possible triggering influences discussed. Pasteurella multocida capsular type B has not been cultivated from clinically healthy cattle and pigs of the region.

Changes in faecal bacteria and metabolic parameters in foals during the first six weeks of life.

Many foals develop diarrhoea within the first two weeks of life which has been suggested to coincide with postpartum oestrus in their dams. To analyse the pathogenesis of this diarrhoea we have determined faecal bacteria in foals and their dams (n=30 each), and serum IGF-1 and γ-globulins for 6 weeks after birth. In addition, effects of β-carotene supplementation to mares (group 1: 1000 mg/day, n=15, group 2: control, n=15) on diarrhoea in foals were studied.

Antimicrobial susceptibilities and occurrence of resistance genes in bovine Helcococcus ovis isolates.

The aim of the study was to investigate antimicrobial susceptibilities of bovine Helcococcus ovis isolates and to detect genes encoding for H. ovis erythromycin and tetracycline resistance. Twenty-nine isolates were included and the minimal inhibitory concentrations (MICs) of seven antimicrobials were determined using test conditions as given in an approved CLSI guideline for the pyridoxal-dependent Abiotrophia spp.

Spontaneous Aujeszky's disease (pseudorabies) in European wild boars (Sus scrofa) in the federal state of Brandenburg, Germany.

In this report two cases of spontaneous Aujeszky's disease (AD, syn. pseudorabies) in European wild boars (Sus scrofa), in the federal state of Brandenburg, Germany, are described. Both animals displayed severe central nervous disturbances, including loss of fear of humans, disorientation, and tremors of head and limbs, and were shot by hunters for laboratory exclusion of rabies.

Helcococcus ovis, an emerging pathogen in bovine valvular endocarditis.

The initial isolation of Helcococcus ovis from a valvular thrombus prompted us to investigate the prevalence of this bacterium in bovine valvular endocarditis. Specimens from 55 affected hearts were examined by culture using Columbia blood agar and cross streaking the inoculated plate with a Staphylococcus aureus strain. As confirmed by 16S rRNA gene sequencing, H.

[Canine brucellosis--a case report].

Brucella (B.) canis was isolated from ejaculate of a 4-year old Korthals-Griffon male dog after occurrence of epididymitis and orchitis. Despite several trials of therapy with different antibiotics relapes occurred, with B.
