Art in the age of artificial intelligence.

There is more to art than AI-created artifacts, but computational creativity is worth pursuing.

Potential of Lactobacillus plantarum IBB3036 and Lactobacillus salivarius IBB3154 to persistence in chicken after in ovo delivery.

The aim of this study was to characterize and compare selected Lactobacillus strains originating from different environments (cow milk and hen feces) with respect to their applicative potential to colonize gastrointestinal track of chickens before hatching from an egg. In vitro phenotypic characterization of lactobacilli strains included the investigation of the important prerequisites for persistence in gastrointestinal tract, such as a capability to survive in the presence of bile salts and at low pH, enzymatic and sugar metabolic profiles, adhesion abilities, and resistance to osmolytes, temperature, and antibiotics. Regarding the resistance of lactobacilli to most of the various stress factors tested, the milk isolate Lactobacillus plantarum IBB3036 showed better abilities than the chicken feces isolate Lactobacillus salivarius IBB3154.

Lactic acid bacteria as a surface display platform for Campylobacter jejuni antigens.

Background: Food poisoning and diarrheal diseases continue to pose serious health care and socioeconomic problems worldwide. Campylobacter spp. is a very widespread cause of gastroenteritis.

Influence of synbiotics delivered in ovo on immune organs development and structure.

Prebiotics and probiotics applied alone or together (synbiotics) can influence the intestinal microbiota and modulate the immune response. We analyzed the impact of in ovo administration of synbiotics on immune system development in Ross (broiler) and Green-legged Partridgelike (GP, dual-purpose fowl) chickens. For in ovo delivery on the 12th day of the eggs incubation, two strains of lactic acid bacteria (LAB) were used, i.

Influence of in ovo prebiotic and synbiotic administration on meat quality of broiler chickens.

A trial was conducted to evaluate the effect of in ovo injection of prebiotic and synbiotics on growth performance, meat quality traits (cholesterol content, intramuscular collagen properties, fiber measurements), and the presence of histopathological changes in the pectoral muscle (PS) of broiler chickens. On d 12 of incubation, 480 eggs were randomly divided into 5 experimental groups treated with different bioactives, in ovo injected: C, control with physiological saline; T1 with 1.9 mg of raffinose family oligosaccharides; T2 and T3 with 1.

Adaptative potential of the Lactococcus lactis IL594 strain encoded in its 7 plasmids.

The extrachromosomal gene pool plays a significant role both in evolution and in the environmental adaptation of bacteria. The L. lactis subsp.

Complete nucleotide sequence of the pCTX-M3 plasmid and its involvement in spread of the extended-spectrum beta-lactamase gene blaCTX-M-3.

Here we report the nucleotide sequence of pCTX-M3, a highly conjugative plasmid that is responsible for the extensive spread of the gene coding for the CTX-M-3 extended-spectrum beta-lactamase in clinical populations of the family Enterobacteriaceae in Poland. The plasmid belongs to the IncL/M incompatibility group, is 89,468 bp in size, and carries 103 putative genes. Besides bla(CTX-M-3), it also bears the bla(TEM-1), aacC2, and armA genes, as well as integronic aadA2, dfrA12, and sul1, which altogether confer resistance to the majority of beta-lactams and aminoglycosides and to trimethoprim-sulfamethoxazole.

Mosaic structure of p1658/97, a 125-kilobase plasmid harboring an active amplicon with the extended-spectrum beta-lactamase gene blaSHV-5.

Escherichia coli isolates recovered from patients during a clonal outbreak in a Warsaw, Poland, hospital in 1997 produced different levels of an extended-spectrum beta-lactamase (ESBL) of the SHV type. The beta-lactamase hyperproduction correlated with the multiplication of ESBL gene copies within a plasmid. Here, we present the complete nucleotide sequence of plasmid p1658/97 carried by the isolates recovered during the outbreak.
