With most epidemiological studies focused on poultry, dogs are often overlooked as a reservoir of , even though these animals maintain close daily contact with humans. The present study aimed to obtain a first insight into the presence and characteristics of spp. in different canine populations in Portugal, and to evaluate its zoonotic potential through genomic analysis. From a total of 125 rectal swabs collected from companion ( = 71) and hunting dogs ( = 54) living in two different settings, rural ( = 75) and urban ( = 50), 32 spp. isolates were obtained. Four different species were identified by Multiplex PCR and MALDI-TOF mass spectrometry, of which ( = 14, 44%) was overall the most frequently found species. Relevant resistance phenotypes were detected in with 93% of the isolates being resistant to ciprofloxacin, 64% to tetracycline, and 57% to ampicillin, and three isolates being multi-drug-resistant. Comparison of the phenotypic and genotypic traits with human isolates from Portuguese patients revealed great similarity between both groups. Particularly relevant, the wgMLST analysis allowed the identification of isolates from human and dogs without any apparent epidemiological relationship, sharing high genetic proximity. Notwithstanding the limited sample size, considering the high genomic diversity of the genetic overlap between human and dog strains observed in this study confirmed that the occurrence of this species in dogs is of public health concern, reinforcing the call for a One Health approach.

Heartworm infection caused by Dirofilaria immitis induces a devastating disease that greatly affects the global canine population. The mechanism leading to heartworm pathology has been attributed to be mostly by mechanical damage of the worm to the dog´s vascular system and immune-mediated, but the latter processes are not completely understood. Autoantibodies targeting host molecules such as lipids and nucleic acids have been described with pathological roles during malaria and COVID-19 and mediating anemia and thrombocytopenia.

Invading species along with increased anthropogenization may lead to hybridization events between wild species and closely related domesticates. As a consequence, wild species may carry introgressed alleles from domestic species, which is generally assumed to yield adverse effects in wild populations. The opposite evolutionary consequence, adaptive introgression, where introgressed genes are positively selected in the wild species, is possible but has rarely been documented.

Dental anomalies are frequent in boars and pigs, and they generally affect the first premolar loci. The prevalence of these dental anomalies was investigated in a large number of populations around the world. These studies mainly focused on the influence of domestication, size, sexual dimorphism or food hardness on these anomalies.

Urinary tract infections (UTIs) are among the most common bacterial infections of both dogs and humans, with most caused by uropathogenic Escherichia coli (UPEC). Recurrent UPEC infections are a major concern in the treatment and management of UTIs in both species. In humans, the ability of UPECs to form intracellular bacterial communities (IBCs) within urothelial cells has been implicated in recurrent UTIs.

Background: Asthma, a chronic inflammatory lung disease, is one of the leading causes of disability, demands on health resources, and poor quality of life. It is necessary to identify asthma-related risk factors to reduce the presence and development of symptoms.
Objective: This study aimed to explore the association of multiple possible factors with asthma symptoms in two subpopulations, children, adolescents, and adults, in six cities in Colombia.
