Understanding why some exotic species become widespread and abundant in their colonised range is a fundamental issue that still needs to be addressed. Among many hypotheses, newly established host populations may benefit from a parasite loss ("enemy release" hypothesis) through impoverishment of their original parasite communities or reduced infection levels. Moreover, the fitness of competing ...
Present study was based on a parasitic survey of captured domestic rat (Rattus rattus) at five selected study sites including, Gampaha, Dalugama, Kadawatha, Sedawatte-Bloemandhal and Wattala,of the Western Province, Sri Lanka. Study also included examination of enteric parasite stages in fresh fecal samples of residents, domestic cats and dogs of the Sedawatte-Bloemandhal, a shanty area. Result...
This study is to detect the presence of Orientia tsutsugamushi in chiggers and host target organs of scrub typhus such as liver, spleen as well as blood. Nine locations of Peninsular Malaysia were chosen; Slim River, Perak; Janda Baik, Pahang; Seremban, Negeri Sembilan; Hulu Langat, Selangor; Raub, Pahang; Bukit Panchor, Pulau Pinang; Gunung Inas, and Ulu Sedim, Kedah and Setiu, Terengganu. Col...
This paper describes the first visit to Jacquemart Island in the south of the subantarctic Campbell Island group. The island contrasts with the main island by the absence of introduced grazing mammals, rats (Rattus spp.) and feral cats (Felis catus), and in the dominance of palatable plant species. A survey of the main vegetation communities was made and bird species seen were recorded. Specime...
This study describes our investigation on the prevalence and molecular identification of bartonellae from Rattus diardii and R. norvegicus in the urban areas of Malaysia. Of 95 rats investigated, Bartonella tribocorum, B. rattimassiliensis, B. coopersplainsensis, B. elizabethae, and B. queenslandensis were isolated from kidney and spleen homogenates of four rats. Bartonellae DNA was amplified f...
Mammalian herbivores can limit plant recruitment and affect forest composition. Loulu palms (Pritchardia spp.) once dominated many lowland ecosystems in Hawai'i, and non-native rats (Rattus spp.), ungulates (e.g. pigs Sus scrofa, goats Capra hircus) and humans have been proposed as major causes of their decline. In lowland wet forest, we experimentally determined the vulnerability of seeds and ...
To the Editor: Bartonella spp. are gram-negative alphaproteobacte-ria that are transmitted between the reservoir and mammal host by he-matophagous insects (1). The genus Yersinia comprises 11 species, of which Y. pestis is the causative agent of plague, a deadly rodent-associated, fleaborne zoonosis (2). Despite the large number of plague cases reported in humans and the large amount of data ab...
بیوسیستماتیک ratlus turkestanicus و dryomys nitedula (جوندگان) مناطق زشک ، طرقبه و گلمکان اطراف مشهد
به منظور مشخص شدن موضع بیوسیستماتیکی رات شمال خراسان نمونه برداری از راتهای کوهپایه های اطراف مشهد با استفاده از تله های زنده گیر انجام گرفت و شناسایی در سه مرحله کاریولوژی، مورفولوژی و مورفومتری صورت گرفت . نتایج حاصل از کاریولوژی اینگونه با کاریوتیپ r.turkestanicus در کشورهای همجوار مقایسه شدند و از نظر مورفولوژیک و مورفومتریک نیز با گونه های rattus rattus و r.norvegicus مقایسه انجام شد. نتای...
Rattus spp trapped in wet markets in Quiapo, Manila and Balayan, Batangas had ectoparasites, Echinolaelaps echidnius (mite), and Polyplax spinulosa (louse). The endoparasites identified were Hymenolepis diminuta; the acanthocephalan Moniliformis moniliformis; Taenia taeniaeformis strobilocercus larvae and Capillaria hepatica in liver; Trichosomoides crassicauda of the urinary bladder; Sarcocyst...
