Total IgE, mosquito saliva specific IgE and CD4+ count in HIV-infected patients with and without pruritic papular eruptions.

Background: Pruritic Papular Eruption (PPE) is a skin disorders found in HIV infected patients. However, the exact etiology of PPE is not documented. It has been suggested that PPE might result from arthropod bites.

A preliminary study of the acaricidal activity of clove oil, Eugenia caryophyllus.

Background: The search for more eco-friendly acaricides has prompted testing of medicinal plants from botanical sources.

Objective: To evaluate the eradication of house dust mites (HDM), Dermatophagoides pteronyssinus, by direct contact using the essential clove oil (Eugenia caryophyllus).

Methods: A pilot study was initiated to determine the killing power of clove oil.

A high resolution melting real time PCR for mapping of filaria infection in domestic cats living in brugian filariosis-endemic areas.

We present here a real time PCR with high resolution melting (HRM) analysis for determining the prevalence and distribution of filarial species in domestic cats residing in brugian filariosis endemic areas of Narathiwat province, Thailand. Filarial species can be clearly distinguished in a single well using a single pair of primers. Blood samples were taken from a total of 2039 domestic cats living in endemic areas.

Effects of high and low temperatures on development time and mortality of house dust mite eggs.

Hatching of Dermatophagoides pteronyssinus eggs was investigated when exposed to temperatures ranging from -70 to +70°C, at varying degrees of humidity (dry and wet heat, direct sunlight) and lengths of time (seven intervals, ranging from 0.5 to 5 h). Exposure to cold was induced using a domestic refrigerator at 4°C, its freezing compartment at -10°C and a deep freezer at -20, -40 and -70°C.

Comparative identification of protein profiles and major allergens of saliva, salivary gland and whole body extracts of mosquito species in Thailand.

Allergic reactions to mosquito bites, such as generalized urticaria or severe local reactions are common problems worldwide. The diverse sources of allergen prepared from different mosquito body parts usage are a major obstacle to obtaining safe and effective tests and immunotherapy for mosquito bite allergy. Thus, the reactions are often not recognized and allergen immunotherapy is seldom used for severe reaction to mosquito bites.

Immunocompromised group differences in the presentation of intestinal strongyloidiasis.

The hospital records of 213 outpatients from Bangkok, Thailand, infected with Strongyloides stercoralis as determined by stool inspections were examined retrospectively for the different clinical presentations ascribed to patients with HIV, those with chronic illness, those who used immunosuppressant drugs and relatively healthy subjects. For HIV patients with strongyloidiasis, the most common symptoms were chronic diarrhea, fever, persistent coughing and loss of weight, but only the first three symptoms were significantly different from other immunocompromised hosts. For healthy patients with strongyloidiasis, acute diarrhea and abdominal pain were the most frequent symptoms.

The potential usefulness of the modified Kato thick smear technique in the detection of intestinal sarcocystosis during field surveys.

A total of 479 stool specimens were collected from rural communities of Ubon Ratchathani Province, Thailand and examined by two techniques: the modified Kato thick smear and the direct smear. The prevalence of Opisthorchis viverrini (14.8%), hookworm (10.

Mite penetration of different types of material claimed as mite proof by the Siriraj chamber method.

Background: There are different materials and principles used in the construction of bed encasings. Although these covers claim to have antimite properties, they might not be mite proof.

Objective: This study evaluated the effectiveness of mite penetration of these covers by using the Siriraj chamber method.
