The estrogen receptor (ER) was visualized immunohistochemically in paraffin sections of the canine uterus using a monoclonal antibody. The ER-expression was quantified by means of an immunohistochemical score. In the uterine horns highest scores were found during proestrus and lowest scores during early metestrus. Staining scores in the uterine body and cervix were high during estrus and metestrus compared with the uterine horns. A negative correlation was found between serum progesterone levels and immunohistochemical staining for ER in the uterine horns. The fluctuations in immunohistochemical scores were more pronounced in the endometrial stroma cells than in the epithelial cells of the uterine horns and therefore stromal cells may be of higher importance than epithelial cells concerning cyclic endometrial changes and uterine pathology.

The uterine artery resistivity index is affected by embryo resorption rate at canine pregnancy diagnosis.

Dipartimento di Scienze Veterinarie, Università di Pisa, Via Livornese (Lato Monte), 1289, San Piero a Grado, PI, Pisa, 56122, Italy.
Article Synopsis
- - The study focused on evaluating the uterine artery resistivity index (RI) through Doppler ultrasonography to assess canine fetal and placental conditions during pregnancy, particularly in relation to embryo resorption rates.
- - It examined 44 bitches of varying breeds and weights, conducting ultrasounds 25 days post-ovulation to gather data on embryo viability and resorption sites, along with factors like age and size group.
- - Statistical analysis revealed a significant relationship between the RI and gestational age and the percentage of embryo resorptions, indicating that these factors may influence uterine blood flow in pregnant dogs.
On-farm epidemiology and phylogenetic evaluation of methicillin and beta-lactam-resistant isolated from dairy cattle and buffaloes with endometritis.

Department of Theriogenology, University of Veterinary and Animal Sciences, Lahore, Pakistan.
Article Synopsis
- - The research investigates a multidrug-resistant pathogen linked to bovine endometritis, focusing on the prevalence and characteristics of methicillin-resistant (MRSA) and beta-lactam resistant strains (BRSA) in dairy cattle and buffaloes.
- - A total of 384 samples were analyzed, revealing a 17.96% prevalence of the pathogen, with MRSA and BRSA confirmed in over 50% and 36% of isolates, respectively; risk factors such as breed and lactation number were significantly associated with the condition.
- - The study warns of significant antibiotic resistance among isolates and calls for more research to understand the economic impact of this pathogen on farms.
Effects of cloprostenol and oxytocin on ultrasonographic changes of uterine horns in postpartum primiparous Hu sheep.

This study aimed to evaluate the effects of exogenous hormones on postpartum ultrasonographic changes of uterine horn in Hu sheep. 90 nulliparous Hu sheep were divided into three groups according to the number of lambs. Each group was further randomly subdivided into three groups (n = 10), a control group (sodium chloride), a PG group (cloprostol), and a PG+OT group (cloprostol + oxytocin).

Women with an aplastic uterus (ESHRE/ESGE classification) or Müllerian agenesis (ASRM MAC 2021) might present with functional uterine remnants. Our study aimed to report the clinical course of symptomatic uterine rudiments in adolescents and adults with Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS). This study involved 20 patients with MRKHS who, between 2012 and 2023, underwent surgery for symptomatic uterine horns at the mean age of 25.

A non-communicating rudimentary uterine horn is a Müllerian abnormality that manifests due to abnormal Müllerian duct development. This abnormality is associated with endometriosis, infertility, and pregnancy complications, including ectopic pregnancy, abnormal fetal presentation, abruption, increased fetal mortality and morbidity, preterm rupture of membranes, preterm birth, intrauterine growth restriction, and uterine rupture. If pregnancy does occur, there is a high risk of complications, most notably rupture of the rudimentary horn.
