Evaluating the Human Risks of Consumption of Foods of Bovine Origin with Ivermectin Residues in Ecuador.

Ivermectin is a widely used antiparasitic in livestock, but its use can result in residues in bovine products and excretions. The objective of the present study was to determine the presence of ivermectin residues in cattle meat, liver, milk, faeces, and urine and assess consumer risk from chronic exposure through contaminated bovine products using a deterministic approach. To determine the presence of ivermectin residues, 124 samples were analysed by liquid chromatography.

Analysis of epidemiological and clinical aspects in cases of fungal osteomyelitis caused by non-Candida species.

Osteomyelitis caused by non-Candida species is rare and often neglected, and current recommendations are based on primarily clinical experience and expert opinion. The objective of this study was to describe a case series of non-Candida fungal osteomyelitis. This retrospective study included 10 patients with non-Candida fungal osteomyelitis.

The Associated Decision and Management Factors on Cattle Tick Level of Infestation in Two Tropical Areas of Ecuador.

Decision-making on tick control practices is linked to the level of knowledge about livestock farming and to the social context in which individuals practice them. Tick infestation is one of the main problems in tropical livestock production. The objective of this study was to characterize tick-control related practices in two tropical livestock areas and their potential association with the level of tick infestation.
