Antimicrobial susceptibility patterns and trends in bacteria isolated from cats and dogs were determined from diagnostic laboratory data from the Atlantic Veterinary College Diagnostic Services Bacteriology Laboratory over a 20-year period. Clinical samples were most commonly from the urinary tract and the ear. spp. and were the bacteria that were most frequently isolated. Increases in percentage resistant were seen with to cephalexin (57% to 61%), spp. to erythromycin (35% to 53%), and (31% to 39%), and spp. (46% to 53%) to enrofloxacin. The frequency of resistance did not change significantly over the study period; however, increased enrofloxacin resistance was identified for canine isolates of spp., spp., spp., and spp. Multidrug resistance was observed in 12% and 9% of the isolates from dogs and cats, respectively. Data from this study could be used to guide empirical antimicrobial selection in companion animal veterinary practices in Atlantic Canada.

Identifying why complex tissue regeneration is present or absent in specific vertebrate lineages has remained elusive. One also wonders whether the isolated examples where regeneration is observed represent cases of convergent evolution or are instead the product of phylogenetic inertia from a common ancestral program. Testing alternative hypotheses to identify genetic regulation, cell states, and tissue physiology that explain how regenerative healing emerges in some species requires sampling multiple species among which there is variation in regenerative ability across a phylogenetic framework.

Xylosandrus crassiusculus Motschulsky and Xylosandrus germanus Blandford are serious ambrosia beetle pests in ornamental nurseries. Three ethanol baits, AgBio low release (LR), AgBio high release (HR), and Trécé are commercially available for use in bottle traps to determine flight activity of adult Xylosandrus spp. However, release patterns of ethanol from these baits under varying temperatures and captures of Xylosandrus spp.

The reddish apocarotenoid β-citraurin, produced by CAROTENOID CLEAVAGE DIOXYGENASE 4b (CsCCD4b), is responsible for peel reddening in citrus (Citrus spp.). Ethylene induces the characteristic red color of citrus peel, but the underlying molecular mechanism remains largely unclear.

Background: Brucellosis is a zoonotic disease caused by Brucella spp., affecting various animals and humans, leading to significant economic and public health impacts. Traditional diagnostic methods, mainly serological, often fail to detect seronegative carriers, which continue to spread the infection.

Aspergillus and Candida are ubiquitous fungi included in the group of high priority in the World Health Organization list of fungal pathogens. They are found in various ecosystems and the environmental role in increasing the resistance to antifungals has been shown. Thus, we aimed to determine the occurrence of Aspergillus spp.
