A pathological and bacteriological study of the mammary glands of beef cows in north Queensland
Research article published in Australian veterinary journal (1976)
Abstract
Pathological and bacteriological studies were made of a total of 507 udders from slaughtered beef cows originating from various locations in northern Queensland. Incidence of supernumerary tests was 28%, their distribution being caudal (80%), intercalary (8%), ramal (5%) and anterior 1%; 6% had both caudal and intercalary teats. They were seen most frequency in British breed and British-Brahman crossbreds (each 29%) and less frequently in Brahmans (22%). Gross lesions were found in 11.4% of cows; these lesions comprised cysts (2.8%), leech infestation (1.0%), mastitis (0.6%), teat occlusionsion (3.9%), papillomatosis (1.2%), cutaneous horns (0.4%), teat fistulas (0.4%), teat trauma (0.6%) and udder fibrosis (0.6%). Mastitis was obviously low in occurrence, while leech infestation and teat occlusion were relatively frequent in cows from one area. Bacteriological examination of single quarters in 364 cows, revealed infection in 154 (42.3%). A total of 199 isolations were made of which 3.5% were recognised mastitis pathogens. Pathological conditions were found, and bacterial isolations were made more frequently in aged than in mature or young cows.

Resumen
A pathological and bacteriological study of the mammary glands of beef cows in north Queensland.
Por qué esto importa para la hirudoterapia
Este estudio anatomopatológico y bacteriológico examinó 507 ubres de vacas de carne sacrificadas en el norte de Queensland para caracterizar la prevalencia y los tipos de enfermedades de la glándula mamaria. El resumen informa diversas lesiones macroscópicas, incluyendo una incidencia del 1,0% de infestación por sanguijuelas, junto con quistes, mastitis, oclusión del pezón, papilomatosis y otras afecciones, así como infección bacteriana en el 42,3% de los cuartos individuales examinados. Aunque el estudio menciona sanguijuelas, está enteramente centrado en la patología veterinaria y la infestación parasitaria incidental del ganado. El artículo no contiene datos relativos al uso terapéutico de las sanguijuelas y carece de relevancia directa para la hirudoterapia o el secretoma de la sanguijuela.
