Stephanurus dentatus infections are parasitic infestations caused by the roundworm Stephanurus dentatus. This worm primarily affects pigs and is commonly found in tropical and subtropical regions, although it has also been reported in temperate areas. It belongs to the family Strongylidae, which comprises a diverse group of parasitic nematodes.
Stephanurus dentatus infections can lead to significant health problems in affected pigs. The adult worms primarily reside in the kidneys, but can also be found in other organs such as the liver and bladder. They cause damage to these organs by directly invading the tissues and stimulating an immune response, leading to inflammation and potential organ dysfunction.
Infected pigs may display a range of clinical signs, including weight loss, reduced appetite, lethargy, and reproductive problems such as infertility or abortions. In severe cases, they may develop kidney or bladder failure, leading to urine retention or blood in the urine. These symptoms can have a detrimental impact on the overall health and productivity of infected pigs, resulting in economic losses for pig farmers.
Diagnosis of Stephanurus dentatus infections typically involves detecting the eggs or larvae of the parasite in fecal samples or in post-mortem examinations. Treatment usually involves the administration of anthelmintic drugs effective against nematodes, although complete eradication of the parasite from an infected pig population can be challenging.
Prevention and control of Stephanurus dentatus infections involve good management practices, including maintaining clean and hygienic pig premises, regular deworming, strict biosecurity measures, and adequate sanitation. The implementation of these measures is essential to reduce the risk of infection and minimize the impact of this parasite on affected pigs.
