Prevalence of pathogens in honey bee colonies and association with clinical signs in southwestern Quebec, Canada
Can J Vet Res. 2024 Apr;88(2):45-54.ABSTRACTHoney bees can be affected by a variety of pathogens, which impacts their vital role as pollinators in agriculture. A cross-sectional study was conducted in southwestern Quebec to: i) estimate the prevalence of 11 bee pathogens; ii) assess the agreement between beekeeper suspicion of a disease and laboratory detection of the causative pathogen; and iii) explore the association between observed clinical signs and pathogen detection in a colony. A total of 242 colonies in 31 apiaries owned by 15 beekeepers was sampled in August 2017. The prevalence of Varroa destructor detection wa...

Comparison of estimations of urinary bladder volume in different scanning positions using 2D linear dimension formula and 3D bladder circumference tracing in client-owned cats
Can J Vet Res. 2024 Apr;88(2):55-65.ABSTRACTUrinary bladder volume (UBV) can be estimated using point-of-care ultrasound. The purpose of this study was to compare 2 UBV estimation methods, i.e., three-dimensional (3D) bladder circumference tracing and 2-dimensional (2D) linear bladder dimension formula, against actual bladder volumes in awake client-owned cats and identify the best scanning position for UBV estimations. Up to 3 paired sets of orthogonal longitudinal and transverse bladder ultrasound images were acquired by a trained clinician from 21 cats positioned in dorsal, right lateral, and left lateral recumbency. UB...

Production of a new tetravalent vaccine targeting fimbriae and enterotoxin of enterotoxigenic < em > Escherichia coli < /em >
The objective of this study was to prepare a novel tetravalent vaccine to effectively prevent piglet diarrhea caused by E. coli. In order to realize the production of K88ac-K99-ST1-LTB tetravalent inactivated vaccine, the biological characteristics, stability, preservation conditions, and safety of the recombinant strain BL21(DE3) (pXKKSL4) were studied, and the vaccine efficacy and minimum immune dose were measured. The results indicated that the biological characteristics, target protein expression, and immunogenicity of the 1st to 10th generations of the strain were stable. Therefore, the basic seed generation was preli...

Comparison of blood profiles between housed and grazing Korean indigenous cattle (Hanwoo)
The objective of this study was to compare the hematology profiles of Korean indigenous cattle (Hanwoo) raised in a barn (housed) or on pasture (grazing). Our findings showed significant differences in the red blood cell (RBC) profiles of these 2 groups. When compared to cattle raised in a barn, a significant decrease in hematocrit (P = 0.000), hemoglobin (P = 0.000), and red blood cells (RBCs) (P = 0.000) and a significant increase in mean cell volume (P = 0.015) and reticulocytes (P = 0.000) were observed in grazing cattle, which indicate regenerative anemia. Furthermore, indirect bilirubin was significantly higher in gr...

SARS-CoV-2 Mu variant in dogs visiting veterinary clinics during the third pandemic peak in Eastern Colombia
AbstractThe global presence of SARS-CoV-2 in household pets is acknowledged, yet documentation remains scarce, leaving many regions unexplored. Thus, our study sought to fill this gap by investigating SARS-CoV-2 presence in dogs visiting veterinary clinics during the third pandemic peak in eastern Colombia. We collected and analyzed 43 oropharyngeal and rectal swabs using real-time PCR assays targeting the Envelope Gene of SARS-CoV-2. Out of these, two dogs tested positive, indicating an infection rate of 4.7%. Further examination through complete sequencing and phylogenetic analysis revealed the lineage B.1.621 for the SA...

Time, temperature and media: the three keys to improve the recovery of Campylobacter fetus subsp. venerealis from preputial bull samples
AbstractThe isolation ofCampylobacter fetus subsp.venerealis (Cfv) from clinical samples is the gold standard for confirming cases of bovine genital campylobacteriosis, an important cause of infertility in cattle and a potential public health concern. Furthermore, isolation is also necessary for the development of autologous vaccines, characterization of strains for antimicrobial susceptibility patterns, etc. Nevertheless, the sensitivity of culture methods is usually low, and there is no standardized protocol to maximize the recovery of Cfv from clinical samples. The aim of the current study is to design a protocol for th...

Estrogen receptors alpha and beta expression in different canine cancer types with an emphasis on hematopoietic malignancies
AbstractEstrogen receptors (ERs) are located in both healthy and neoplastic tissues. The type of estrogen receptor expressed varies depending on its location, tumor type, and species. Estrogen action is mediated by binding to ER and activating the transcriptional and signaling processes that result in the control of gene expression. There are two main types of estrogen receptors: ER alpha (ER α) and ER beta (ERβ). Both receptors are functionally different, they may act antagonistically and are distributed in different tissues but their structure is similar – as they are composed of 5 different domains: A/B, C, D, E, an...
