The apicomplexa Toxoplasma gondii is capable of actively proliferating in numerous types of nucleated cells, and therefore has a high potential for dissemination and resistance. Thus, the present work aimed to correlate the inoculum concentrations and amount of post-infection parasites with porcine hematological parameters (including biochemistry) through in vitro culture.

Background Cryptosporidiosis is a crucial zoonotic global health concern which can be treated by alternative medicinal plants extracts. Aim of the study The study was carried out to assess the therapeutic efficacy of Citrus sinensis peel ethanolic extract on Cryptosporidium-infected mice. Methods Two doses of Citrus sinensis extract; high dose (30 mg/kg) and low dose (15 mg/kg) were investigated compared to the commo

Cryptosporidium is an important cause of gastroenteritis globally and the main agent of waterborne outbreaks caused by protozoan parasites. Water monitoring for Cryptosporidium oocysts is by detection and enumeration using stained slide microscopy. Species identification (known as genotyping) may be undertaken post hoc and remains a specialist test, only undertaken in some laboratories.

Infections with Cryptosporidium spp. Constitute a substantial public health burden and are responsible for widespread production losses in cattle herds. Reducing disease and shedding of Cryptosporidium oocysts is an important One Health goal. There are very few therapeutic options available to treat cryptosporidiosis.

Toxoplasma gondii, a protozoan parasite, is responsible for toxoplasmosis.

Toxoplasmosis is a disease with a worldwide prevalence that is caused by Toxoplasma gondii. Pyrimethamine and sulfadiazine are two pharmacological agents commonly used to treat of this infection. However, they are accompanied by some side effects. Therefore, the identifying of new drugs with low toxocytosis seems to be a matter of vital importance.

Intestinal epithelial cells (IECs) reside in a highly anaerobic environment that is subject to daily fluctuations in partial oxygen pressure (pO2), depending on intestinal tissue perfusion.

Acute Toxoplasma gondii infections can influence the liver as well as other organs.

Giardia lamblia (G. lamblia) is an important cause of severe malabsorption, weight loss, physical and mental retardation especially in infants and children throughout the world. Metronidazole (MTZ) is the standard drug used for their treatment which possesses several drawbacks with low efficacy. Gold nanoparticles possess a broad-spectrum antimicrobial activity and could be considered as a future alternative to many microbial agents.

Toxoplasma gondii infects almost all warm-blooded animals, and toxoplasmosis is a common zoonotic parasitic disease worldwide. A nested PCR with high specificity and sensitivity was developed in this study based on the data collected on the infection rate of toxoplasmosis in chickens in Shandong province, and the effect of low temperature on the infectivity of tachyzoites was investigated. The sampling data showed that the total prevalence of T.

Toxoplasma gondii, as other apicomplexa, employs adhesins transmembrane proteins for binding and invasion to host cells. Search and characterization of adhesins is pivotal in understanding Apicomplexa invasion mechanisms and targeting new druggable candidates. This work developed a machine learning software called ApiPredictor UniQE V2.0, based on two approaches: support vector machines and multilayer perceptron, to predict adhesins proteins from amino acid sequences.

Infections caused by protozoan parasites are a major public health concern globally. These infections are commonly diagnosed during water-borne outbreaks, necessitating accurate and highly sensitive detection procedures to assure public health protection. Current molecular techniques are challenged by several factors, such as low parasite concentration, inefficient DNA extraction methods, and inhibitors in environmental samples.
