The present study evaluated, in laboratory and field, the efficacy and safety of formulations of Pelargonium graveolens (geranium - G), Origanum majorana (oregano - O) commercial essential oils (EO) and thymol (T) to control of Rhipicephalus sanguineus sensu lato. In the laboratory, three formulas (A: 2% tween 80%, B: powder and C: nanoemulsion) by a mixture of these components (GOT) were prepared and evaluated, and the best one was used to assess its safety and field application against R. sanguineus s.

The most economically significant ectoparasites in the tropics and subtropics are ixodid ticks, especially Rhipicephalus annulatus and Rhipicephalus sanguineus. Years of extensive use of the readily available acaricides have resulted in widespread resistance development in these ticks, as well as negative environmental consequences. Benzyl alcohol (BA) has been frequently used to treat pediculosis and scabies, and it may be an effective alternative to commonly used acaricides.

Schistosomiasis is one of the major health problems in many tropical and developing countries. Infection takes place once cerceriae penetrate human skin, then it changed into schistosomules. The schistosomules takes iron in the form of heme from host's haemoglobin, ferritin and transferrin.

Meat-borne parasites are Sarcocystis species, Toxoplasma gondii, Taenia saginata, Taenia solium and Trichinella spiralis. A total of 300 animals including 100 cattle, 100 goat, and 100 pigs, slaughtered in El-Minia governmental slaughterhouses. From each animal, five samples were taken from different muscles (esophageal, tongue and cardiac) and different organs (liver and brain).

Blastocystis spp., one of the most common parasites colonizing the human intestine, is an extracellular, luminal protozoan with controversial pathogenesis. The host's immune response against Blastocystis spp.

Article Synopsis
  • The study assessed the effects of sulfamethoxazole (SMX) on Toxoplasma gondii infection in wild-type C57BL/6 mice after they were infected with a specific strain of the parasite.
  • Different organs reacted differently to SMX treatment: some showed reduced T. gondii levels (like skin and kidney), while others did not fully clear the parasite (like brain, heart, and lung), and some organs (tongue, skeletal muscle, small intestine) eradicated it completely with treatment.
  • Higher SMX concentrations were found in the brains, hearts, and lungs of infected mice compared to uninfected ones, suggesting that chemotherapy is critical for lowering the parasite load and preventing recurring infections even in healthy

Controversy surrounding the pathogenic role of Blastocystis spp. in humans and lack of well-established diagnostic criteria led to debates concerning the treatment for that organism. Furthermore, some strains develop resistance against the recommended drugs.

Plasmodium parasites multiply within host erythrocytes, which contain high levels of iron, and parasite egress from these cells results in iron release and host anemia. Although Plasmodium requires host iron for replication, how host iron homeostasis and responses to these fluxes affect Plasmodium infection are incompletely understood. We determined that Lipocalin 2 (Lcn2), a host protein that sequesters iron, is abundantly secreted during human (P.
