the protective capacity of the crude extracts from larval and nymphal stages of hyalomma anatolicum anatolicum was examined in the new zealand white rabbits. the rabbits were randomly divided into 3 groups of five animals. the rabbits in groups 1 and 2 were immunized with crude extracts of larval and nymphal antigens, respectively and group 3 was served as control. following challenge of each r...

An antigen-capture enzyme-linked immunosorbent assay (ELISA) was developed for detecting North American isolates of Borrelia burgdorferi in larval, nymphal, and adult ticks. The assay uses an anti-OspA monoclonal antibody (H5332) for antigen capture and biotin-labelled polyclonal sera with streptavidinhorseradish peroxidase for signal generation. The assay recognized 15 of 15 North American B. ...

We evaluated human risk for infection with Babesia microti at a site in eastern Switzerland where several B. microti-infected nymphal Ixodes ricinus ticks had been found. DNA from pooled nymphal ticks amplified by polymerase chain reaction was highly homologous to published B. microti sequences. More ticks carried babesial infection in the lower portion of the rectangular 0.7-ha grid than in th...

Borrelia burgdorferi lipoprotein Lp6.6 is a differentially produced spirochete antigen. An assessment of lp6.6 expression covering representative stages of the infectious cycle of spirochetes demonstrates that the gene is solely expressed during pathogen persistence in ticks. Deletion of lp6.6 in infectious B. burgdorferi did not influence in vitro growth, or its ability to persist and induce i...

The life cycle of Rhipicephalus evertsi evertsi Neumann, 1897, is discussed under the following headings: larval feeding; larval drop; nymphal feeding; nymphal drop; nymphal moulting; adult feeding; adult drop; preoviposition period; oviposition period and incubation. Special attention has also been given to the development of both male and female reproductive organs, gametogensis and mating.

Population flactuations of the sunn pest, Eurygaster integriceps Putton was studied in the wheat and barley fields of five regions of Shahre Rey including, Esmail Abad, Shahed University, Dorsun Abad, Ghaleh Nou and Nazar Abad from 25th March 2009 to 10th June of 2009. Additionally important parasitoids of the sunn pest were collected and identified in different regions of Varamin and Shahre Re...

Female engorgement weight, oviposition, and molting times of larvae and nymphs of Amblyomma maculatum Koch (Acari: Ixodidae) were studied at various photoperiods under constant humidity and temperature in the laboratory. Ticks were held at photoperiods of 0:24, 10:14, 12:12, or 14:10 (L:D) h from egg through unfed nymphal stage and then at either the same or a different regime from fed nymphs t...

Ticks are parasites that usually suck the blood of wild or domestic animals; rarely, they ingest human blood and spread various febrile infectious diseases along with skin problems. Out of 40 cases of tick bite reported in Korea, only 3 were caused by nymphal ticks, and tick bites by nymphal Amblyomma testudinarium have not been reported previously. Herein, we report a rare case of tick bite by...

The causal agents of Lyme disease in North America, Borrelia burgdorferi and Borrelia mayonii, are transmitted primarily by Ixodes scapularis ticks. Due to their limited metabolic capacity, spirochetes rely on the tick blood meal for nutrients and metabolic intermediates while residing in the tick vector, competing with the tick for nutrients in the blood meal. Metabolomics is an effective meth...
