- Comparison of a conventional and nested PCR for diagnostic confirmation and genotyping of Orientia tsutsugamushi.
- Janardhanan J1, Prakash JA2, Abraham OC1, Varghese GM3.Author information 1Medicine Unit I and Infectious Diseases, Christian Medical College, Vellore, Tamil Nadu 632004, India.2Department of Clinical Microbiology, Christian Medical College, Vellore, Tamil Nadu 632004, India.3Medicine Unit I and Infectious Diseases, Christian Medical College, Vellore, Tamil Nadu 632004, India. Electronic address: georgemvarghese@hotmail.com.AbstractA nested polymerase chain reaction (PCR) targeting the 56-kDa antigen gene is currently the most commonly used molecular technique for confirmation of scrub typhus and genotyping of Orientia tsutsugamushi. In this study, we have compared the commonly used nested PCR (N-PCR) with a single-step conventional PCR (C-PCR) for amplification and genotyping. Eschar samples collected from 24 patients with scrub typhus confirmed by IgM enzyme-linked immunosorbent assay were used for DNA extraction following which amplifications were carried out using nested and C-PCR methods. The amplicons were sequenced and compared to other sequences in the database using BLAST. Conventional PCR showed a high positivity rate of 95.8% compared to the 75% observed using N-PCR. On sequence analysis, the N-PCR amplified region showed more variation among strains than the C-PCR amplified region. The C-PCR, which is more economical, provided faster and better results compared to N-PCR.

- A prospective study on distribution of eschar in patients suspected of scrub typhus.
- Munegowda K1, Nanda S, Varma M, Bairy I, Vidyasagar S.Author information 1Senior Research Fellow, Department of Microbiology, Melaka Manipal Medical College, India.AbstractScrub typhus is an acute febrile illness caused by a tick bite infected with the bacteria Orientia tsutsugamushi. The clinical diagnosis is difficult as the symptoms are similar to other febrile illnesses such as dengue, typhoid, leptospirosis and so on. An eschar, if present, will narrow down the provisional diagnosis towards scrub typhus. There are no data on the preferential sites of tick bites in an Indian population. We present here the preferential sites of tick bites in a South Indian population of 123 cases positive for eschar. Geographically, clothing styles vary leading to the differences in the areas of skin exposed to the bite and thus the formation of eschars. Scrub typhus, if not treated, may lead to fatal complications. As scrub typhus is one of the most under-reported illnesses in the world, clinicians should look for the presence of an eschar in the preferential sites at least to narrow down the diagnosis and treatment.

- Pancreatitis in scrub typhus: a rare complication.
- Dhakal M1, Dhakal OP, Bhandari D.Author information 1Department of Medicine, Sikkim Manipal Institute of Medical Sciences, Gangtok, Sikkim, India.AbstractScrub typhus is a zoonosis transmitted by a trombiculid mite which introduces bacteria of Orientia tsutsugamushi by its bite. The acute febrile illness is characterised by eschar at the site of the bite with maculopapular rashes and local and/or generalised lymphadenopathy. The disease is endemic in the tsutsugamushi triangle. Sikkim, a small Himalayan north-eastern state, is also not unaffected where outbreaks of the disease have been reported. The clinical spectrum of the disease ranges from mild to fatal depending on the virulence of the bacterial strain, susceptibility of the host and promptness of the treatment. In severe cases, there can be multiple organ involvement. Pancreatitis is a serious and unusual complication of this disease, which was seen in our presentation. A 22-year-old man, diagnosed to have scrub typhus, developed pancreatitis in the second week of the illness and responded well to medical treatment.
