AI Article Synopsis
- The sheep botfly larvae (Oestrus ovis) typically infest sheep and goats but can occasionally affect humans, leading to temporary survival in the nose or eyelids.
- A 47-year-old woman developed symptoms like sneezing and facial swelling after visiting Cape Verde, which were found to be caused by three larvae in her sinuses, later removed via endoscopy.
- Such infestations in healthy individuals are rare and may occur in areas where botflies are endemic, typically in those with compromised immune responses.
Article Abstract
Background: Larvae of the sheep botfly (Oestrus ovis) normally have sheep or goats as host. In humans the larvae can survive for a short time in the nose or under the eyelids, after which they die or are sneezed out.
Case Description: We describe a 47-year-old woman who during a stay in the Cape Verde Islands developed symptoms of sneezing, a swollen face and an itchy feeling in her nose. These symptoms were due to an infestation of three fully-developed larvae of the O. ovis species in her sinus maxillaries which were later evacuated by endoscopy.
Conclusion: In exceptional cases larvae of the O. ovis species can fully mature in a healthy person after a visit to an endemic area. Development into the mature stage has only been described in patients with a poor mucosal immune response.

Background: Anthelmintic resistance in ruminants is a widespread problem that has a severe impact on productivity and animal welfare. The helminth Haemonchus contortus is generally considered the most important parasite in small ruminants due to its high pathogenicity and the widespread occurrence of anthelmintic resistance in it. Although the molecular mechanisms associated with resistance against the anthelmintics benzimidazoles (BZs) and levamisole are relatively well understood, the resistance mechanisms against the widely used anthelmintic macrocyclic lactones (MLs) ivermectin (IVM) and moxidectin (MOX) remain poorly understood.

In this study, molecular analysis was used to show the possibility of transovarial and transstadial transmission of Borrelia valaisiana in Ixodes ricinus ticks in the natural biotopes of North-Western Russia. Female ticks collected in nature were fed on rabbits; larvae obtained from these females were fed on white mice. Eggs, female ticks after the egg deposition, larvae and nymphs of ticks after overwintering were studied for Borrelia burgdorferi s.

Article Synopsis
- - The study evaluates the effectiveness of two bio-inhibitors (seed-QS from a plant and larvae-OOL from an insect) in preventing corrosion of carbon steel in hydrochloric acid (HCl) environment, focusing on different concentrations of these inhibitors.
- - Various electrochemical techniques and spectroscopic analyses were employed to assess the steel’s corrosion behavior and the characteristics of the protective films formed by the inhibitors.
- - Results showed that the optimal concentration of the bio-inhibitors improved corrosion resistance by 85%, with the seed-QS proving to have a stronger adsorption on the steel surface compared to larvae-OOL, as confirmed by quantum calculations and molecular dynamics simulations.

Haemonchus contortus is a highly pathogenic gastrointestinal nematode that parasitizes the abomasum of cattle, sheep, and other ruminants. Long-term use of large quantities of ivermectin (IVM) to control H. contortus has resulted in the development of drug resistance.
