There are no recommended drugs to treat cattle infected with the protozoan Tritrichomonas foetus (TF). Ivermectin, widely used in the treatment of intestinal parasites, was found effective against some protozoa growing in vitro. Here, its effectiveness against a TF line was investigated. Trophozoites were incubated in media with increasing concentrations of ivermectin and mortality was determined after 24 h. Ivermectin killed cells with a mean maximum effective concentration (EC50) of 2.47 μg mL-1. The effective concentration of ivermectin was rather high for a formulation suitable for systemic treatment. However, topical treatment of animals against TF could still be considered and tested.

Tritrichomonas foetus is a protozoan parasite that causes bovine trichomonosis (also referred to as trichomoniasis) resulting in substantial economic loss in extensive grazing systems. The parasite colonises the reproductive tracts of both male and female cattle, being asymptomatic in males but causing early reproductive failure in infected females. This systematic review aimed to examine research manuscripts describing the development of T.

Bovine trichomoniasis is a reproductive illness that affects cattle causing pyometra, early to mid-pregnancy miscarriages, and lower birth rates. is a flagellated protozoan which first discovered in France in 1888 and composts three phases during its lifecycle including trophozoite, cyst, and pseudocyst. In addition, several factors contributed to the prevalence of trichomoniasis and fall into three categories are management, cow, and bull-related factors.

The early evolution of eukaryotes and their adaptations to low-oxygen environments are fascinating open questions in biology. Genome-scale data from novel eukaryotes, and particularly from free-living lineages, are the key to answering these questions. The Parabasalia are a major group of anaerobic eukaryotes that form the most speciose lineage of Metamonada.

- The study aimed to check for the presence of Tritrichomonas foetus in male reproductive tissues of bulls that tested positive and analyzed how post mortem tissue acidity affects testing accuracy.
- Eight bulls were euthanized, and samples from their testicles, epididymis, and accessory sex glands were collected; however, T foetus was not found in any of these tissues.
- Researchers found that as the pH of the penis and prepuce decreased after death, the cycle threshold values increased, indicating that pH changes could influence the effectiveness of detecting genetic material over time.

Article Synopsis
- Trichomonas vaginalis causes trichomoniasis, a widespread STD that affects over a hundred million people, and resistance to common treatments like metronidazole is increasing.
- The study explored using Tritrichomonas foetus, a related parasite, as a better animal model for testing new treatments since it caused reliable infections in mice, unlike T. vaginalis.
- Findings showed that while some drugs had similar effectiveness on both parasites, proteasome inhibitors were less effective on T. foetus, suggesting the need for targeted drug development and further understanding of genetic differences between the two organisms.
