Article Synopsis
- - The New World screwworm fly (Cochliomyia hominivorax) is a major cause of myiasis in animals, including pets like dogs, highlighting the need for effective treatments.
- - A study tested the effectiveness of the drug lotilaner, which is typically used for ticks and fleas, on 11 dogs suffering from myiasis by administering a single oral dose and measuring larval expulsion over time.
- - Results showed that lotilaner achieved a larval expulsion rate of 93% within 6 hours and complete efficacy (100%) within 24 hours, indicating it is a rapid and effective treatment for myiasis in dogs.

Article Synopsis
- Bartonella is a type of bacteria linked to mammals, and bats serve as natural reservoirs for many pathogens affecting both human and animal health.
- A study in São Luís Island, Brazil, found no presence of Bartonella in bat blood samples, but identified it in 20% of bat flies from a specific family.
- Genetic analysis revealed that the Bartonella sequences from these flies were closely related to those found in bats in other countries, suggesting a wider distribution of Bartonella among bat flies in South America.
Cochliomyia hominivorax (Coquerel, 1858), the New World screwworm, causes primary myiasis in wild and domestic animals in tropical and subtropical regions of Brazil. Although this species is considered to occur throughout the country, organized information about its recorded distribution has not been available until now. This article aimed to provide a comprehensive review of the historical and current data published on both immature (myiasis) and adult stages of C.

An analysis of analytical sensitivity and specificity showed that the antigen MBP-p26rec reacted positively with a reference World Organization for Animal Health serum and demonstrated no cross-reaction against sera from vaccinated animals in either test. The diagnostic characteristics were evaluated and presented excellent values.

Male cross-bred Anglo-Nubian goat kids between 3 and 5 months of age were dewormed at the beginning of the experiment. The goat kids were divided into one group that received weekly 24 g oral doses of A.
