Big cities of Argentina are characterized by a strong social and economic fragmentation. This context enables the presence of urban rodents in close contact to the human population, mostly in the peripheral areas of the cities. Urban rodents can harbor a large variety of zoonotic pathogens. The aim of this study was to molecularly characterize spp. and spp. in urban rodents from the area of Gran La Plata, Buenos Aires province, Argentina. The species of urban rodents captured and tested were , and and were detected in and respectively. spp. DNA was not detected in any of the kidney samples tested. No significant differences were observed between the prevalence of bacteria and rodent and environmental variables such as host sex, presence of stream and season by Generalized Linear Model analysis. These results confirm the role of urban rodents as infection sources of spp., suggesting the need to implement public health measures to prevent the transmission of spp. and other zoonotic pathogens from rodents to humans. was not detected in this set of samples.

Capybaras (Hydrochoerus hydrochaeris) are hosts for several parasites of public health importance, including Cryptosporidium spp. Therefore, this study aimed to perform the molecular characterization of Cryptosporidium spp. in fecal samples from capybaras inhabiting urban areas.

Experimental studies of chronic noise exposure in modern urban life testified about oxidative stress due to the corresponding hormones effects leading to accumulation of reactive oxygen species and endothelial dysfunction. This study aims to evaluate the protective effect of α2-adrenoblockers to modulate oxidative stress and corticosterone levels due to chronic noise exposure. To achieve this, we examined the effects of beditin (2-aminothiozolyl-1,4-benzodioxane) and mesedin (2-(2-methyl-amino-thiozolyl)-1,4-benzodioxane hydrochloride), along with changes in corticosterone, Ca2 + content, and morphological alterations in various tissues under noise-induced stress.

Angiostrongylus cantonensis, commonly known as the rat lungworm, causes Eosinophilic meningitis in humans. Our study aimed to investigate the prevalence and distribution of this parasite in rats in Haiti. Rats were trapped at 8 sites, 7 in Artibonite (rural region) and one in an urban area of Port-au-Prince.

The black rat Rattus rattus is an exotic and synanthropic rodent prominent in Brazil and with high adaptation to urban areas. The species have an omnivorous diet feed on human food resources, potentially becoming infected and spreading infectious agents that cause zoonoses such as leptospirosis, leishmaniosis, Chagas disease, and toxoplasmosis, which are significant public health concerns in the country. We analyzed the epidemiologic profile of R.

Humans may play a key role in providing small prey mammals spatial and temporal refuge from predators, but few studies have captured the heterogeneity of these effects across space and time. Global COVID-19 lockdown restrictions offered a unique opportunity to investigate how a sudden change in human presence in a semi-urban park impacted wildlife. Here, we quantify how changes in the spatial distributions of humans and natural predators influenced the landscape of fear for the California ground squirrel (Otospermophilus beecheyi) in a COVID-19 pandemic (2020) and non-COVID (2019) year.
