Food handlers have a major role in transmission of food-borne parasitic infections including intestinal helminths. The objective the present study was to assess global prevalence helminthic parasites among food handlers. Multiple databases (PubMed, Scopus, ProQuest, Web Science, Science Direct and Google Scholar) were searched for literature published from 1990 2022. Pooled estimated using meta...

Prevalence of arthropod-borne parasites often differs drastically between host sexes. This sex-related disparity may be related to physiological (primarily hormonal) differences that facilitate or suppress replication of the pathogen in host tissues. Alternately, differences in pathogen prevalence between host sexes may be owing to differential exposure to infected vectors. Here, we report on t...

Aggregation of parasites amongst hosts is important for the epidemiology of vector-borne diseases because hosts that support the majority of the vector population are responsible for the majority of pathogen transmission. Ixodes ricinus ticks transmit numerous pathogens of medical importance including Borrelia burgdorferi s.l. and tick-borne encephalitis virus. One transmission route involved i...

Vector-borne diseases are principally zoonotic diseases transmitted to humans by animals. Pathogens such as bacteria, parasites and viruses are primarily maintained within an enzootic cycle between populations of non-human primates or other mammals and largely non-anthropophilic vectors. This 'wild' cycle sometimes spills over in the form of occasional infections of humans and domestic animals....

introduction: intestinal parasites have world wide prevalence and are considered to be as one of the leading hygienic and economic problems in the world. it can be said that there is nowhere in the world without parasitic infestations. the present study was conducted to determine the prevalence of intestinal parasites in patients referring to yazd central laboratory in 2000-2002. methods: the p...

background: the aim of the study was to determine the helminthic species occurring in great gerbil rhombomys opimus collected from maraveh tappeh, golestan province, northeast iran. methods : during 2010-2011, a total of 77 r. opimus were captured from rural areas of maraveh tap-peh, golestan province, using sherman live traps and examined for infectivity with any larva or adult stages of helmi...

background: blastocystis  is a zoonotic protozoan parasite habit in intestinal tract of humans and wide range of animals. because of the mysterious nature and unknown or less-known aspects of blastocystis, comprehensive information about epidemiology of this parasite is not available. the objective of this study was to investigate the available parasitology studies during the last decade in ira...

Apicomplexa tick-borne hemoparasites, including Babesia bovis, Babesia microti, and Theileria equi are responsible for bovine and human babesiosis and equine theileriosis, respectively. These parasites of vast medical, epidemiological, and economic impact have complex life cycles in their vertebrate and tick hosts. Large gaps in knowledge concerning the mechanisms used by these parasites for ge...

BACKGROUND The rising global temperature is predicted to expand the distribution of vector-borne diseases both in latitude and altitude. Many host communities could be affected by increased prevalence of disease, heightening the risk of extinction for many already threatened species. To understand how host communities could be affected by changing parasite distributions, we need information on ...

Vector-borne parasites are commonly predicted to be less virulent to the vector than to the definitive host as the parasite gains little by harming its main route of transmission. Here we assess the empirical evidence from systems in which insects are vectors for vertebrate, plant, and invertebrate parasites. The body of evidence supports lower (but nonzero) parasite virulence to vectors than t...
