Promoting Success and Persistence in Pandemic Times: An Experience With First-Year Students.

The transition and adaptation of students to higher education (HE) involve a wide range of challenges that justify some institutional practices promoting skills that enable students to increase their autonomy and to face the difficulties experienced. The requirements for this adaptation were particularly aggravated by the containment and sanitary conditions associated with coronavirus disease 2019 (COVID-19). With the aim of promoting academic success and preventing dropout in the first year, a support program was implemented for students enrolled in two courses in the area of education at a public university in northern Portugal during the first semester of 2020/2021.

Use of β-caryophyllene to combat bacterial dental plaque formation in dogs.

Background: Periodontal disease is a highly prevalent illness that affects many dogs, reaching up to 85 % prevalence in individuals over the age of 4 years. Currently the drug of choice for combating the formation of dental plaque in these animals, the etiologic agent of the disease, is chlorhexidine, which has several side effects reported. Thus, surveys are conducted throughout the world in order to identify potential substitutes for antimicrobial therapy and prevention of periodontal disease.

Distribution of infectious bronchitis virus strains in different organs and evidence of vertical transmission in natural infection.

On the basis of partial sequencing of the infectious bronchitis virus (IBV) S1 gene, this study investigated the molecular diversity of the virus in two life periods of a batch of breeding hens at the field level. The chicks were vaccinated against IBV on the second day of life with the vaccine Ma5, but at the age of 18 days, they exhibited clinical signs and macroscopic lesions compatible with avian infectious bronchitis (IB). In the clinical disease stage, the Ma5 vaccine strain was detected in the trachea, lungs, and small intestine of the chicks, while IBV variants were detected in the bursa of Fabricius and kidneys.

Genotype distribution of Mycoplasma hyopneumoniae in swine herds from different geographical regions.

Genetic heterogeneity of Mycoplasma hyopneumoniae in pigs has been reported, however there has been limited reproducibility on the molecular methods employed so far. The aim of this study was to modify and standardize a high-resolution multiple locus variable number tandem repeat analysis (MLVA), to investigate the genetic variability of M. hyopneumoniae circulating in the United States of America (USA), Brazil, Mexico and Spain.

Biofilm formation on biotic and abiotic surfaces in the presence of antimicrobials by Escherichia coli Isolates from cases of bovine mastitis.

Escherichia coli is a highly adaptive microorganism, and its ability to form biofilms under certain conditions can be critical for antimicrobial resistance. The adhesion of four E. coli isolates from bovine mastitis to bovine mammary alveolar (MAC-T) cells, biofilm production on a polystyrene surface, and the expression profiles of the genes fliC, csgA, fimA, and luxS in the presence of enrofloxacin, gentamicin, co-trimoxazole, and ampicillin at half of the MIC were investigated.

Increased production of biofilms by Escherichia coli in the presence of enrofloxacin.

The literature has demonstrated that subinhibitory concentrations of some antimicrobials are able to induce biofilm formation by certain bacterial species. Biofilms present in the mammary glands of cattle contribute to antimicrobial resistance, resulting in the appearance of persistent mastitis and consequent great losses to the dairy sector worldwide. The present study aimed to investigate the induction of biofilm formation by enrofloxacin in Escherichia coli isolates obtained from bovine mastitis.
