    Summary

    A novel Stephanofilaria species, similar to S. stilesi, causes lesions on cattle in Queensland. This study details the parasite and its pathological effects on the animals.

    Area of Science:

    • Veterinary Parasitology
    • Dermatology in Livestock

    Background:

    • Stephanofilariasis is a parasitic disease affecting livestock.
    • Lesions caused by Stephanofilaria parasites can impact animal health and productivity.

    Purpose of the Study:

    • To identify and describe a Stephanofilaria species causing lesions in cattle.
    • To provide macroscopic and histopathological details of the lesions and the parasite.

    Main Methods:

    • Field observation and sample collection from affected cattle in northern Queensland.
    • Macroscopic examination of external lesions.
    • Histopathological analysis of tissue samples.
    • Morphological description of the identified parasite.

    Main Results:

    • A Stephanofilaria species, morphologically similar to S. stilesi, was identified as the causative agent.
    • Lesions were observed on the head, neck, and sternum of affected cattle.
    • Macroscopic and histopathological features of the lesions were documented.
    • Key morphological characteristics of the parasite were described.

    Conclusions:

    • The identified Stephanofilaria species represents a significant cause of parasitic skin lesions in cattle in northern Queensland.
    • Further research may be needed to fully differentiate this species from S. stilesi and assess its economic impact.
