Campylobacter and risk factors associated with dog ownership: a retrospective study in household and in shelter dogs.

Campylobacteriosis has been the most frequently reported zoonotic disease in humans in Europe. The scientific literature has reported that the role of dogs may be relevant. The objectives of this work are to improve the knowledge about Campylobacter spp. carriage, infection and antimicrobial resistance in household and shelter dogs in Italy, and to assess risk factors at the dog/human interface. During the 2015­2016 period, rectal swabs were collected from 431 household vet­visiting dogs and 173 dogs housed in shelters. A total of 3 veterinary clinics, located in three Italian regions (Abruzzo, Molise and Tuscany) and 10 shelters, five in Abruzzo and five in Molise, were included in the study. Relevant risk factors for the transmission of Campylobacter spp. from dogs to humans were assessed by means of a questionnaire administered to owners of household dogs. For Campylobacter spp. isolation, selective cultivation methods were used, followed by confirmation and species identification with the PCR method. Phenotypic antibiotic resistance profiles assayed using antimicrobial susceptibility testing were combined. Campylobacter spp. were isolated from 9 household dogs (2.1% CI 1.1% ­ 3.9%) and from 13 shelter dogs (7.5 % CI 4.5% ­ 12.4%). In household dogs C. jejuni was the most represented species (0.9%). In shelter dogs, the most common species was C. jejuni (5.2%). Campylobacter spp. isolates were resistant to ciprofloxacin (22.73%), nalidixic acid (22.73%), tetracyclines (27.27%), streptomycin (9.09%) and erythromycin (4.55%). The main C. jejuni Clonal Complex identified in dogs were CC21, CC45, CC206, CC403, CC42 and CC658. The risk of contracting Campylobacteriosis from dogs remains a concrete reality. This risk is increased in the presence of common habits, as shown by the data from the questionnaire. Prevalence control of Campylobacter spp. in household and shelter dogs would be important in order to reduce the transmission to humans.

Informality in the time of COVID-19 in Latin America: Implications and policy options.

This paper analyzes the dynamics of the labor market in Latin America during the COVID-19 pandemic. After a decade of a virtuous circle of growth with the creation of formal jobs, the pandemic has had an considerable impact on the region's labor market, generating an unparalleled increase in the proportion of the inactive population, considerable reductions in informality, and, in contrast, smaller fluctuations in formal jobs. In this context, the formal sector, given its lower flexibility, became a "social safety net" that preserved the stability of employment and wages. Based on the findings presented in this paper, it is projected that, starting in 2021, informality will grow to levels higher than those of the pre-COVID-19 era-with 7.56 million additional informal jobs-as a result of the population returning to the labor market to compensate for the declines in incomes. According to the simulations presented, postponing or forgiving income tax payments and social security contributions conditional on the generation of formal jobs could reduce the growth of informality by 50 to 75 percent. Achieving educational improvements has the potential to reduce it by 50 percent.

Antimicrobial resistance in Enterococcus strains isolated from healthy domestic dogs.

Enterococci are opportunistic bacteria that cause severe infections in animals and humans, capable to acquire, express, and transfer antimicrobial resistance. Susceptibility to 21 antimicrobial agents was tested by the disk diffusion method in 222 Enterococcus spp. strains isolated from the fecal samples of 287 healthy domestic dogs. Vancomycin and ampicillin minimum inhibitory concentrations (MICs) and high-level aminoglycoside resistance (HLAR) tests were also performed. Isolates showed resistance mainly to streptomycin (88.7%), neomycin (80.6%), and tetracycline (69.4%). Forty-two (18.9%) isolates showed an HLAR to streptomycin and 15 (6.7%) to gentamicin. Vancomycin and ampicillin MIC values showed 1 and 18 resistant strains, respectively. One hundred and thirty-six (61.2%) strains were classified as multidrug resistant and six (2.7%) strains as possibly extensively drug-resistant bacteria. Enterococcus faecium and Enterococcus faecalis were the most prevalent antimicrobial resistant species. Companion animals, which often live in close contact with their owners and share the same environment, represent a serious source of enterococci resistant to several antibiotics; for this reason, they may be a hazard for public health by providing a conduit for the entrance of resistance genes into the community.
