1. Native parasite acquisition provides introduced species with the potential to modify native host-parasite dynamics by acting as parasite reservoirs (with the 'spillback' of infection increasing the parasite burdens of native hosts) or sinks (with the 'dilution' of infection decreasing the parasite burdens of native hosts) of infection. 2. In New Zealand, negative correlations between the pre...

OBJECTIVE To investigate the endemic characteristics of Metorchis orientalis (M. orientalis)in the Huainan area, Anhui province, China. METHODS The first-intermediate host, second-intermediate host and reservoir hosts were collected, and the endemic characteristics of M. orientalis were examined through field investigation and artificial infection. RESULTS Investigation was completed in 89 ...

Fleas are the vectors of many communicable diseases that are normally found in oriental rats. Climate and environmental changes influence the habitat and migration patterns of vectors. In this study, the oriental rat flea abundance, represented as total flea index, was determined in correlation to host specificity and various environmental factors. The number of hosts and fleas calculated from ...

The Coronavirus disease 2019, identified by Chinese researchers to be the caused by a novel enveloped betacoronavirus, Severe Acute Respiratory Syndrome Coronavirus- 2 which was first isolated in Wuhan, China has been declared a global pandemic by the world health organization. The virus has several structural proteins that contributed to its pathogenesis such as spikes, membrane, envelop and n...

Vector-borne zoonotic disease agents, which are known to often infect multiple species in the wild, have been identified as an emerging threat to human health. Understanding the ecology of these pathogens is especially timely, given the continued anthropogenic impacts on biodiversity. Here, we integrate empirical scaling laws from community ecology within a theoretical reservoir-vector-pathogen...

HIV establishes a latent reservoir in a small pool of resting CD4+ T cells early in the infection of a new host. This viral reservoir has a very slow rate of decay and it is resistant to anti-retroviral therapy and the immune surveillance. This reservoir poses a significant obstacle to the eradication of virus in an infected individual. It is thus of importance to understand how this reservoir ...

Background: An epidemiological study was carried out on the vector(s) and reservoir(s) of cutaneous leishmaniasis in rural areas of Kalaleh District, Golestan Province during 2006 2007. Methods: Totally 4900 sand flies were collected using sticky papers and were subjected to molecular methods for detection of leishmanial parasite. Results: Phlebotomus papatasi was the common species in outdoor ...

Abstract Among people living with human immunodeficiency virus type 1 (HIV-1), the long-term persistence of a population cells carrying transcriptionally silent integrated viral DNA (provirus) remains primary barrier to developing an effective cure. Ongoing cell division via proliferation is generally considered be driving force behind this latent HIV-1 reservoir. The contribution mechanism (cl...
