Goats are the one of the most susceptible domestic species to toxoplasmosis affecting animal health and production. The present study aimed to determine the seroprevalence of T. gondii infection in dairy goats from Rio de Janeiro, Brazil, as well as to evaluate associated risk factors, parasitic DNA detection in raw goat milk samples, and attempts to isolate the parasite from raw goat milk samples.

Cystic and alveolar echinococcosis are severe zoonotic diseases characterized by long asymptomatic periods lasting months or years. Viable Echinococcus spp. eggs released into the environment through the feces of canids can infect humans through accidental ingestion via hand-to-mouth contact or consumption of contaminated food or water.

The hemoflagellate parasite is transmitted by triatomine kissing bugs and may co-infect humans together with its Chagas disease-causing congener . Using real-time quantitative polymerase chain reaction (RT-qPCR) and antimicrobial assays, we studied () the temporal and spatial distribution of in common bed bugs, , following oral ingestion and hemocoelic injection of and () the immune responses of bed bugs induced by infections. Irrespective of infection mode, no live were present in the bed bugs' hemolymph, salivary glands, or feces.

Article Synopsis
- Aedes aegypti mosquitoes are key carriers of dengue, and factors like urbanization, climate change, and trade are affecting their populations.
- Higher temperatures have been shown to impact insect mortality and fertility, with this study focusing on how heat influences the fertility of Ae. aegyti across different generations.
- Results indicated that while mosquitoes can acclimate to heat, their fertility declines with increasing temperatures, affecting both male and female mosquitoes’ ability to reproduce and produce viable offspring, which could impact their populations in warmer climates.

Antimicrobial resistance poses a global public health threat, compelling the search for alternative treatments, especially in resource-limited settings. The increasing ineffectiveness of traditional antibiotics has intensified the need to explore medicinal plants as viable therapeutic options. This study sought to compare the efficacy of certain medicinal plants used in Owerri, Nigeria, for treating pathogenic bacteria against traditional commercial antibiotics.
