Perineural anaesthesia is an essential part of lameness investigation in horses. Painful reactions to injections imply a high risk of accidents for veterinarians. To evaluate the efficacy of two topical anaesthetic creams on desensitization of the skin at two perineural injection sites and to evaluate the effects these formulations may have on pain perception distally to the application sites. Randomized, blind, prospective study. 14 healthy horses were randomly divided in two groups of 7 horses each, one treated with EMLA and one with PLIAGLIS preparations. The mechanical nociceptive threshold (MNT) was recorded via pressure algometer at the baseline and one hour after application (T1) on palmar and palmar digital nerve blocks sites. Skin sensation was also assessed on the distal limb, recording MNT on the coronary band and on both bulbs of the heels. Data were compared with a 3-way ANOVA statistical analyses. No significant difference was encountered in the MNT values between baseline records and records at T1 at the control sites. A significant difference of MNT values was detected between the two time points in the treated limbs. The significant sources of variation in our study were the time and the presence of anaesthetic cream. The type of treatment did not determine any differences. Furthermore, no significant difference of MNT values at sites distal to treatment was recorded between the two time points, both in the treated limb and control limbs. Both formulations are effective to obtain superficial skin desensitization.Equine salmonellosis is caused by several Salmonella serotypes, including Salmonella Newport, which cause enterocolitis and diarrhea. Treatment usually includes the administration of antibiotics. However, since multidrug-resistant Salmonella is commonly detected, alternative options to control the pathogen are needed. One of these options is the use of specific egg yolk antibodies (IgY) for passive immunotherapy. Thus, the aim of our work was to produce IgY antibodies against an equine S. Bcl-2 pathway Newport strain and assess their in vitro inhibitory activity. To this end, laying hens were immunized with an inactivated S. Newport strain by using either Freund's or Montanide adjuvant and egg yolk extracts were obtained. The levels of specific IgY antibodies against Salmonella in sera and egg extracts were determined by dot-blot and microagglutination. Besides, the IgY extracts were characterized by total protein analysis, SDS-PAGE, Western Blot, and inhibition of bacterial motility. IgY extracts showed high purity (87.7 to 91.8 %), high microagglutination titers, and the ability to inhibit the motility of the bacterium. The results using Montanide were similar to those using the traditional Freund's adjuvant. Thus, Montanide may also be a good adjuvant to produce IgY. IgY-technology represents a potential tool for the control of salmonellosis in horses.Dwarfism is a skeletal disorder that causes abnormal growth. In Miniature horses, dwarfism can occur as chondrodysplastic dwarfism, an autosomal recessive disorder associated with five mutations (D1, D2, D3*, D4 and c.6465A > T variant) in the aggrecan (ACAN) gene. The aim of this study was to evaluate the expression of aggrecan (at the gene and protein level) and specific cytokines (IL-1β, IL-6, and TNF-α) in the articular cartilage of Miniature horses with chondrodysplastic dwarfism (D4/c.6465A > T genotype). Metatarsal bone samples from eight dwarf Miniature horses were collected for histopathological analysis, and articular cartilage was collected to detect and quantify aggrecan levels through Western blotting and determine the relative expression levels of ACAN, IL-1β, IL-6, and TNF-α through qPCR. All affected animals presented chondrodysplasia-like lesions with disorganization of the chondrocyte layers and reduced the amount of an extracellular matrix. No significant difference in aggrecan expression levels in uncleaved samples from the dwarf and control groups (composed of phenotypically normal animals of similar age and breed (P = .7143)) was found using Western blotting. qPCR revealed that ACAN gene expression was higher in the affected animals than in normal animals (P = .0119). No significant difference in cytokine levels was detected between the groups. Mutant aggrecan may interfere with normal cellular function, leading to chondrodysplasia and the observed phenotypic findings.This case series discusses the clinical presentation, ultrasonographic findings, treatment, and outcome of 5 horses with superficial digital flexor tendon (SDFT) lesions within the carpal canal. The horses' ages ranged from 11-28 years, and presented with an acute, unilateral forelimb lameness which worsened following proximal limb flexion. The presence of a lesion within the SDFT of the carpal canal was accompanied by a mild swelling of the palmar carpal region in most cases. Diagnostic anesthesia of the ulnar nerve, when performed, abolished the lameness. Ultrasound evaluation revealed an increased cross-sectional area (CSA) of the superficial digital flexor tendon compared to the contralateral, sound limb and a loss of tendon fiber architecture within the palmar aspect of the affected tendon, most readily identifiable upon longitudinal ultrasound images. Three out of the five horses returned to their previous level of performance, and two were euthanized. A back at the knee carpal region conformation was associated with a poorer prognosis in these cases. An intratendinous fibroma was identified on histopathological analysis of one-horse following euthanazia, which has been recorded in a complementary short communication.Reliable and simple tests are constantly being sought to enable the quick detection of acute kidney injury in humans and animals. Diagnosis of subclinical AKI in horses, mainly in field practice, is difficult. An ultrasound scan is a routine test performed when kidney disease is suspected. The aim of the study was to establish the value of the renal resistive index (RRI) in intrarenal arteries in horses with clinical AKI and compare it to that of healthy horses. The second goal was to determine whether potentially nephrotoxic agents can influence RRI. The kidney ultrasonography examination was performed in 30 healthy horses, 11 horses with AKI and 30 horses at risk for AKI (10 colic horses, 10 horses receiving gentamicin and 10 horses receiving NSAIDs). RRI values were measured using pulsed-wave Doppler. Differences in RRI between groups were observed only in the right kidney. Horses with AKI had significantly higher RRI values compared to healthy horses. In the risk group, there was no effect of potentially nephrotoxic agents on the RRI value.Bcl-2 pathway
