Control of the sheep blowfly relies on insecticides, however resistance is currently impacting on their efficacy. The use of insecticides in combination (mixtures) is considered to be a useful strategy to delay resistance under some circumstances. The present study aimed to examine the combination of spinosad with macrocyclic lactones in order to determine if the two drug classes showed any interactions that would impact on the usefulness of a combination product for flystrike control.

Introduction: This paper presents (a) the progress made towards achieving the 2023 Lymphatic Filariasis (LF) Mass Drug Administration (MDA) campaign goals, (b) the estimated financial savings resulting from integrating LF MDA into Polio immunization campaigns, and (c) the best practices, challenges, and recommendations.
Methods: In 2023, 21,336,057 people in 83 districts were affected by LF and required Preventive Chemotherapy (PC). The National NTD Control Programme (NTDCP) conducted three phases of LF MDA campaigns in those districts.

The aim of this work was to analyse the spatiotemporal heterogeneity of Rhipicephalus microplus (Canestrini, 1888) (Acari: Ixodidae) resistance to chemical acaricides at intra-farm level under different environmental (favourable and unfavourable areas for tick development) and management (different schemes of acaricides applications) conditions using ivermectin as a model. The in vitro larval immersion test (LIT) was used to determine quantitatively the levels of resistance to ivermectin in the different populations and subpopulations of R. microplus analysed.

Detection of Strogyloides-specific IgG antibodies in urine and serum has been used in diagnostic and epidemiological studies on strongyloidiasis. However, the usefulness of these assays in assessing responses to anthelmintic treatment is unclear. Thus, we evaluated the diagnostic performance and temporal profiles of Strongyloides-specific IgG antibodies in a cohort of participants at baseline and post-treatment.
