The Thai Journal of Veterinary Medicine

An 11-year-old neutered female Labrador Retriever presented with a 1-week history of respiratory distress, lethargy and anorexia. On physical examination, the dog exhibited dyspnea with a rapid and shallow breathing pattern. Thoracic radiography showed diffuse nodular or miliary interstitial patterns, which raised suspicion of bacterial, fungal and parasitic infections and metastatic tumors. Bronchoalveolar lavage (BAL) was performed and the culture yielded no growth of infectious agents, including bacteria and fungi. A presumptive diagnosis of pulmonary mesothelioma was made based on malignant mesothelial cells on BAL fluid cytology. Therefore, this is a report identifying suspected pulmonary mesothelioma using BAL fluid in …

Radiographic Cardiac Indices For The Evaluation Of Cardiac And Left Atrial Sizes In Healthy Wistar Albino Rats (Rattus Norvegicus), Mehmet Alper ÇETİNKAYA, Mahir KAYA 2022 Chulalongkorn University

Radiographic Cardiac Indices For The Evaluation Of Cardiac And Left Atrial Sizes In Healthy Wistar Albino Rats (Rattus Norvegicus), Mehmet Alper Çeti̇nkaya, Mahir Kaya

The Thai Journal of Veterinary Medicine

This study was performed for the purpose of comparing vertebral heart score (VHS), radiographic left atrial dimension (RLAD) and vertebral left atrial size (VLAS) values derived from plain and contrast right lateral thoracic radiographs from 70 healthy, young adult Wistar albino rats and to identify reference values for these radiographic cardiac indices. Measurements were taken by two observers blinded to the study data. VHS, RLAD and VLAS median values and reference ranges were 8v and 7-9.3v for plain radiography, 8.2v and 7.4-9.5v for contrast radiography (P< 0.000), 1.3v and 1-1.8v for plain radiography, 1.3v and 1.1-1.6v for contrast radiography (P <0.000) and 1.9v and 1.4-2.4v for plain radiography and 1.95v 1.5-2.4v for contrast radiography (P<0.001), respectively. The only statistically significant difference was observed in terms of gender between VHS values from plain and contrast radiographs (P<0.02). Intraobserver and interobserver measurements revealed excellent agreement for radiographic cardiac indices obtained from contrast radiography. The study measurements indicate that contrast radiography provides a more effective quantitative assessment of cardiac and left atrial sizes than plain radiography. The radiographic cardiac index measurements presented in this study can serve as a reference baseline for both veterinarians and experimental cardiovascular studies.

Odor Detection Of Cancer Cell Metabolites By Scent-Detection Dogs, Geontae Park, Dongwook Kim, Seongsoo Jeong, Dongsun Park, Gonhyung Kim

The Thai Journal of Veterinary Medicine

Dogs have a superior olfactory system; thus, they have been trained and used to detect various nonbiological and biological scents. In addition, many studies have recently reported dogs’ ability to detect the odor of certain cancers or cancer cells. A previous study documented that a dog trained to detect a certain malignant cancer cell could also detect another, unfamiliar malignant cancer cell well, implying that these two cancer cells share a certain specific odor. Thus, given the hypothesis that malignant cancer cells of different origins may contain a common cancer-specific odor, the purpose of the present study was to evaluate …

A Systematic Review: The Source Of Antimicrobial Resistance Pathogenic Bacteria On Slaughtered Meat, Cross-Contamination Or Self-Contamination?, Xin Wu, Fanan Suksawat, Sunpetch Angkititrakul, Chunlian Song, Jun Chai, Yifang Zhang, Xianghua Shu, Huiyan Xing, Wengui Li

The Thai Journal of Veterinary Medicine

Slaughtered meat has been identified as one of the major vehicles for forming antimicrobial resistance (AMR). It is still believed that AMR pathogens introduced by overusing antimicrobials in the breeding industry are directly brought in from farm animals. This disregards however the fact that many gut pathogens do not settle on muscle parts; the presence of gut pathogens on muscle products does not directly correlate to farm feeding. To investigate whether the source of AMR bacteria on slaughtered meat was cross-contamination or self-contamination, many peer-reviewed publications were studied to assess if the observational studies focused on AMR pathogenic bacteria association …
