Halophilanema prolata (Nematoda: Allantonematidae) is described from the intertidal bug, Saldula laticollis on the Oregon coast. Infection rates ranged from 0 % to 85% depending on the microhabitat in the intertidal zone.

Prevalence and risk factors for Giardia duodenalis infection among children: A case study in Portugal

Parasites and Vectors — Fri, 27 Jan 2012 05:00:00 +0100

We investigated the prevalence of Giardia duodenalis infection and identified possible associated risk factors in a healthy paediatric population from Portugal. We highlight the high prevalence of G.duodenalis in these children, as well as the parents¿ education level as the main risk factor. Of interest, we also found an association between G. duodenalis and Helicobacter pylori infections. Image: Giardia duodenalis cysts stained by FICT. (Source: Parasites and Vectors)

Low and seasonal malaria transmission in the middle Senegal River basin: identification and characteristics of Anopheles vectors.

Parasites and Vectors — Mon, 23 Jan 2012 05:00:00 +0100

This study, conducted in the Middle Senegal River basin demonstrates that, although various malaria vectors are present all the year round in this region, malaria transmission remains low and limited to the short rainy season. Image: Senegal River in Guede village. (Source: Parasites and Vectors)

The transmission of Leishmania infantum chagasi by the bite of the Lutzomyia longipalpis to two different vertebrates

Parasites and Vectors — Thu, 19 Jan 2012 05:00:00 +0100

We established a transmission model of Leishmania infantum chagasi by the bite of Lutzomyia longipalpis, the vector of American visceral leishmaniasis. The parasites were successfully transmitted to mice and hamsters indicating that both animals are good experimental models.Image: An infected sandfly biting a mouse ear (transmission experiment). Inset: The mouse ear after bite (red dot). (Source: Parasites and Vectors)

First report on the occurrence of Rickettsia slovaca and Rickettsia raoultii in Dermacentor silvarum in China

Parasites and Vectors — Thu, 19 Jan 2012 03:02:11 +0100

This study reported the occurrence of R. raoultii and R. slovaca in XUAR, China and suggests that D. silvarum could be involved in the transmission of rickettsial agents in China. Image: An stereomicroscope view of a Dermacentor silvarum adult female. (Source: Parasites and Vectors)

Ecological factors related to the widespread distribution of sylvatic Rhodnius ecuadoriensis populations in southern Ecuador

Parasites and Vectors — Fri, 13 Jan 2012 05:00:00 +0100

Searches conducted in 23 localities in southern Ecuador show an abundance of sylvatic triatomines associated with squirrel, bird and rat nests, which may jeopardize the effectiveness of Chagas disease control campaigns. Image: Nests of the squirrel Sciurus stramineus are frequently infested with R. ecuadoriensis. (Source: Parasites and Vectors)

SYBR Green-based Real-Time PCR targeting kinetoplast DNA can be used to discriminate between the main etiologic agents of Brazilian cutaneous and visceral leishmaniases

Parasites and Vectors — Thu, 12 Jan 2012 05:00:00 +0100

SYBR Green-based real-time PCR targeting kDNA minicircles can differentiate between Leishmania subgenera through the amplicons dissociation kinetic. This methodology was further validated with human clinical specimens and field sandflies from Brazil. Image: Characteristic SYBR Green dissociation curve profiles of kDNA conserved regions amplicons from both Leishmania subgenera. (Source: Parasites and Vectors)
