Morphological characterization of Setaria worms collected from cattle.

Area of Science:

• Veterinary Parasitology
• Helminthology
• Animal Health

Background:

• Setaria species are common nematodes affecting livestock globally.
• Accurate identification of Setaria species is crucial for understanding their epidemiology and impact on animal health.
• Morphological characterization aids in differentiating closely related species.

Purpose of the Study:

• To identify and morphologically characterize Setaria species infecting cattle and buffaloes.
• To determine the prevalence of different Setaria species in a cattle population.

Main Methods:

• Collection of Setaria specimens from cattle and buffaloes.
• Detailed morphological examination of male and female worms.
• Microscopic identification based on key morphological features.

Main Results:

• Three Setaria species were identified: Setaria digitata, Setaria cervi, and Setaria labiatopapillosa.
• In a screening of 500 cattle, 187 (37.4%) harbored Setaria infections.
• Setaria digitata was the most prevalent species (56.8% of infected animals), followed by S. cervi (24.13%) and S. labiatopapillosa (18.96%).

Conclusions:

• Morphological analysis confirmed the presence of S. digitata, S. cervi, and S. labiatopapillosa in the studied livestock.
• Setaria digitata represents a significant parasitic burden in the investigated cattle population.
• Detailed morphological data are essential for accurate diagnosis and control strategies against Setaria infections in ruminants.
