Reproduction of the Escherichia coli peritonitis syndrome in laying hens.

Reproduction of the Escherichia coli peritonitis syndrome in laying hens. Avian Pathol. 2013 Apr;42(2):157-62 Authors: Landman WJ, Heuvelink A, van Eck JH Abstract In five experiments, each consisting of four or six groups with seven or 14 brown laying hens per group, birds were inoculated with an Escherichia coli strain, isolated from a layer with the E. coli peritonitis syndrome (EPS) by different routes between 23 and 33 weeks of age. Aerosol-exposed hens inhaled 10(5.1) to 10(6.2) colony-forming units per hen; hens inoculated by other routes received 10(7.6) to 10(9.1) colony-forming units per hen. In one experiment, one-half of the birds of each group were injected intraperitoneally with sterile egg yolk simultaneously with E. coli. Dead and surviving birds were necropsied and bacteriological examination of the bone marrow was performed. The percentage of birds with EPS that died was 89 (159/179). Nearly all dead birds showed septicaemia (155/159 = 97%), while most had septicaemia and peritonitis (126/159 = 79%). Surviving hens with EPS (20/179 = 11%) showed chronic peritonitis and inactive ovaries. Taking all experiments together, exposure of hens by the intravenous, intratracheal and intraperitoneal routes induced EPS in 84% (41/49), 80% (55/69) and 76% (16/21), respectively, while aerosol and intravaginal exposure resulted in EPS percentages of 57% (32/56) and 49% (28/57), respectively. Except for orally inoculated groups (7/56 = 13% EPS), in all othe...

ConclusionsWe found that EFVF is safe with regard to acute toxicity in rats as well as genotoxicity such as mutagenesis or clastogenesis under the present experimental conditions. These results might support the safety of EFVF as a potential therapeutic material for the traditional use or pharmaceutical development.Graphical abstract

CONCLUSIONS: in Mexico, there is a very low prevalence of PI-IBS in patients from a tertiary-referral center. However, it varies according to the surrogate-criteria used. The later needs to be taken into account when performing PI-IBS studies. PMID: 31718206 [PubMed - as supplied by publisher]

ConclusionThis is the first report on the synthesis of two novel ginsenosides, namely glucosyl-ginsenoside Rh2 and diglucosyl-ginsenoside Rh2 from Rh2 by utilizing recombinant glycosyltransferase isolated from L. rhamnosus. Moreover, diglucosyl-ginsenoside Rh2 might be a new candidate for treatment of inflammation, obesity and skin whiting, and especially for anticancer.Graphical abstract

Abstract Healthcare-associated infections (HAIs) not only bring additional medical cost to the patients but also prolong the length of stay (LOS). 2119 HAI case-patients and 2119 matched control-patients were identified in 68 hospitals in 14 primary sampling provinces of 7 major regions of China. The HAI caused an increase in stay of 10.4 days. The LOS due to HAI increased from 9.7 to 10.9 days in different levels of hospitals. There was no statistically significant difference in the increased LOS between different hospital levels. The increased LOS due to HAI in different regions was 8.2 to 12.6 days. Comparing b...

The objective of this study was to isolate and characterize genotoxin-encoding E. coli from healthy and ill small mammal pets examined at a veterinary clinic and at two animal adoption centers. E. coli isolates were cultured from fecal samples and biochemically characterized. A total of 65 animals, including mice, rats, rabbits, guinea pigs, and hedgehogs, were screened. Twenty-six E. coli isolates were obtained from 24 animals. Twelve of the 26 isolates (46.2%) were PCR-positive for the pks genes clbA and clbQ. Two isolates (7.7%) were PCR-positive for cnf. All isolates were PCR-negative for cdt. All genotoxin-encoding is...

The Seychelles biota contains a mix of ancient taxa with Gondwanan origins and young taxa that arrived there via dispersals. We investigate the phylogenetic position of an enigmatic, critically endangered, Seychellean endemic of the coffee family (Rubiaceae), Psathura/Psychotria sechellarum, and assess whet...
