چکیده

In order to establish the most sensitive and specific method in the detection of Rickettsia tsutsugamushi in Leptotrombidium deliense , mice and patients, a comparative study on DNA extraction, PCR, hybridization and PCR-hybridization was conducted. The results showed that the sensitivity of PCR-hybridization was 10 times higher than that of PCR and 1000 times higher than that of hybridization. Quick DNA extraction method could take the place of phenol-chloroform method to prepare DNA template when detecting the rickettsiae in mice and patients' blood by PCR. De-inhibitor quick DNA extraction method could improve the detection rate of rickettsiae from chigger mites. Key word s: Leptotrombidum deliense , Rickettsia tsutsugamushi , PCR, hybridization, PCR-hybridization

Efficiency of Leptotrombidium chiggers (Acari: Trombiculidae) at transmitting Orientia tsutsugamushi to laboratory mice.

Thirteen different laboratory colonies of Leptotrombidim chiggers [L. chiangraiensis Tanskul & Linthicum, L. deliense Walch and L. imphalum (Vercammen-Grandjean &Langston)] were evaluated for their ability to transmit Orientia tsutsugamushi (Hyashi) to mice. Of 4,372 transmission attempts using individual chiggers from all 13 colonies, 75% (n = 3,275) successfully infected mice. Transmission ra...

Scrub Typhus: An Emerging Threat

Scrub typhus is caused by Orientia tsutsugamushi (formerly Rickettsia) and is transmitted to humans by an arthropod vector of the Trombiculidae family (Leptotrombidium deliense and L. akamushi). It is the most common re-emerging Rickettsial infection in India and many other South East Asian countries. In fact, scrub typhus is confined geographically to the Asia Pacific region, a billion people ...

Investigation of the role of Blankaartia acuscutellaris (Acari: Trombiculidae) as a vector of scrub typhus in central Thailand.

Monthly collections of rodents were conducted in Phitsanulok Province, central Thailand in 1993 to investigate the role of the mite Blankaartia acuscurellaris as a vector of scrub typhus. Overall, a total of 41 rodents were collected and examined for the presence of the red colored larvae of B. acuscutellaris and yellow larvae of Leptotrombidium deliense and Ascoshoengastia sp. A total of 787 B...

Rickettsial diseases and ectoparasites from military bases in Japan.

Ectoparasitic arthropods are often vectors of rickettsiosis. We conducted a survey of ectoparasites on U.S. military facilities throughout Japan with the use of specimens submitted by pest control, public health, and veterinary personnel. Over 1,600 individual ectoparasites were collected. Fifteen species were identified, including several significant vectors of human diseases such as scrub typ...

Seroprevalence of Scrub typhus among Febrile Patients in a Tertiary Care Hospital in Thiruvananthapuram, Kerala

Scrub typhus is a rickettsial infection caused by Orientia tsutsugamushi that belongs to the family Rickettsiaceae and transmitted by some species of trombiculid mites "chiggers", particularly a Leptotrombidium deliense. A necrotic eschar at the inoculating site of the mite is pathognomic of Scrub typhus. Scrub typhus is a zoonosis and is a widespread disease in Asia and Pacific Islands. Fever ...
