Excretory urography can track down morphological changes in the urinary bladder associated with urachal anomalies in calves for early diagnosis.

Objective: To investigate radiographic detection by excretory urography of morphological changes in the urinary bladder associated with urachal anomalies in calves.

Methods: Excretory urography was performed to detect morphological changes in the urinary bladder of 13 calves, of which 6 were nondysuric with swelling of umbilical region and 7 were dysuric without clinical umbilical swelling from November 2022 through April 2024.

Results: The urinary bladder was delineated in all 13 calves after excretory urography.

The growth-stimulating factor of Treponema phagedenis from bovine digital dermatitis lesions.

Bovine digital dermatitis (BDD) is an infectious skin disease of the hoof characterized by painful ulcerations that cause lameness in dairy cattle. Cell-free supernatants (CFS) of Falsiporphyromonas endometrii predominantly isolated from BDD lesions had the highest growth-stimulating effect on Treponema phagedenis among BDD-associated bacteria. Butyric acid was detected at a concentration of 45.

Comprehensive Analyses of the Bacterial Population in Non-Healing Claw Lesions of Dairy Cattle.

Non-healing claw lesions (NHCLs) are a newly characterized disorder affecting the deep dermis of the hoof in dairy cattle. Although NHCLs are thought to be associated with bovine digital dermatitis (BDD), their precise etiology is not yet understood. To investigate the bacterial populations present in each type of NHCL (toe necrosis: TN, non-healing white line disease: nhWLD, and a non-healing sole ulcer: nhSU), and the newly added entity non-healing verrucous-like lesions (nhVLL), 16S rRNA-based metagenomic analysis with next-generation sequencing (NGS) was employed.

Efficacy of fosfomycin in the prevention of postoperative infection following transurethral resection of bladder tumor during periods of limited cefazolin, cefotiam, and cefmetazole supply.

Introduction: In March 2019, cefazolin availability was limited owing to the contamination of the drug substance. In addition, there was a difficulty in supplying drugs alternative to cefazolin, such as cefotiam and cefmetazole. In our Department of Nephro-urology, we used fosfomycin-based drugs to substitute cefazolin as perioperative preventive antibacterial drugs.

Detection of the Plasmodium falciparum Kelch-13 gene P553L mutation in sporozoites isolated from mosquito salivary glands in South-Central Vietnam.

Background: Plasmodium falciparum has developed resistance against artemisinin in Southeast Asia. Mutations in the P. falciparum Kelch-13 (Pfk13) gene are associated with artemisinin resistance in vitro and in vivo.
