However, information regarding these filarids and their epidemiological patterns remains scarce in Malaysia. The present study aimed to determine the infection rate and associated risk factors of filarial parasites in dogs in Malaysia.

Generation of human scFv-IgG1Fc antibodies for detection of lymphatic filarial recombinant antigens, BmR1 and BmSXP.

Lymphatic filariasis is a neglected parasitic disease that affects millions in tropical and subtropical countries and is caused by Wuchereria and Brugia species. Specific and sensitive detection methods are essential in mapping infected areas where rapid tests are needed to cover underdeveloped and remote regions, which facilitates eliminating the disease as a public health problem. A few commercialized rapid tests based on antigen or antibody detection are available, but the former only detects infection by Wuchereria species and cross-reacts with nonlymphatic filaria, whereas antibody detection might provide positive results of previous infection.

Measuring fitness of Kenyan children with polyparasitic infections using the 20-meter shuttle run test as a morbidity metric.

Background: To date, there has been no standardized approach to the assessment of aerobic fitness among children who harbor parasites. In quantifying the disability associated with individual or multiple chronic infections, accurate measures of physical fitness are important metrics. This is because exercise intolerance, as seen with anemia and many other chronic disorders, reflects the body's inability to maintain adequate oxygen supply (VO(2) max) to the motor tissues, which is frequently linked to reduced quality-of-life in terms of physical and job performance.

Elimination of lymphatic filariasis in India--a successful endeavour.

World Health Assembly resolution in 1997 for elimination of lymphatic filariasis (ELF) by 2020 made all the filaria endemic countries in the world to put efforts for its elimination by progressively reducing and ultimately interrupting the transmission of lymphatic filariasis. National Health Policy, 2002 has set the goal for elimination of lymphatic filariasis (ELF) in India by the year 2015. In pursuit to achieve this goal, the strategy of mass drug administration (MDA) with annual single dose of diethylcarbamazine citrate (DEC) tablets was introduced in 2004 in all the filaria endemic states of the country and 202 districts were covered.

Strengthening of mass drug administration implementation is required to eliminate lymphatic filariasis from India: an evaluation study.

Background & Objectives: The mass drug administration (MDA) is one of the strategies to eliminate lymphatic filariasis in India. Eleven districts are endemic for the disease in Madhya Pradesh state of India, which conduct MDA activities annually. A mid-term evaluation was conducted with the objectives to review the progress of the single dose of di-ethyl-carbamazine (DEC) administration, and to understand the functioning of the programme to recommend mid-term amendments.

Awareness of health personnel about lymphatic filariasis and mass drug administration in Kerala State.

The mass drug administration programme to eliminate lymphatic filariasis with DEC in Kerala was started in 1997, extended to all the 11 endemic districts by 2005. Since the beginning of Mass drug Administration, the drug consumption rate was found to be not satisfactory. The reasons for noncompliance indicated that the community is not fully convinced about the programme.

Distribution of filarial elephantiasis and hydrocele in Matara district, Sri Lanka, as reported by local leaders, and an immunological survey in areas with relatively high clinical rates.

To eliminate lymphatic filariasis by means of mass drug administration, it is essential to have reliable data on the disease distribution and prevalence in targeted areas. In Matara district, Sri Lanka, self-administered questionnaires were mailed to 2105 local leaders questioning the presence and the numbers of elephantiasis and hydrocele cases. The information provided by them revealed that elephantiasis was clearly aggregated in the southern part of the district along the coast, while hydrocele was distributed rather evenly in the whole district, including Deniyaya region where no endemic filariasis had been known.

Presence and gradual disappearance of filaria-specific urinary IgG4 in babies born to antibody-positive mothers: a 2-year follow-up study.

A total of 14 Sri Lankan pregnant women, who were anti-Brugia pahangi urinary IgG4 positive, and their 14 newborn babies were followed up for the urinary antibody for 2 years by enzyme-linked immunosorbent assay. Eight babies showed positive IgG4 reaction, at least once within 4 months after birth. Urinary antibody titers of mothers and their babies measured around the perinatal period showed a significant positive correlation, suggesting that baby's IgG4 was transferred from the mother through the placenta.
