Analyzed to View Trend of Microfilaria Intensity of Brugia spp. in Domestic Cats at Surat Thani Province

Brugia spp. microfilariae in cats at Subdistricts 1 and 2, Sincharoen District, Surat Thani Province, were detected for 4 years (2010-2013) after completion of the National Program to Eliminate lymphatic filariasis (PELF) (2002-2006). The annual microfilaria positive rate was found in cats' venipuncture of 80% coverage to the number of cats each year, i.e., 5.67 (10/176), 3.26 (6/184), 3.78 (9/238) and 11.46 (25/218) found, respectively and 2 cats were found infected with 250 and 353 mcf. Most cats were found in the 2-4 years age group with a greater ratio of males than females (2:1). However, the important issues from these findings are whether new infections exist among other domestic cats or not and that they should be detected continuously. Even though the filarial species of Brugia spp. was not confirmed and compared with human filariasis, but this Brugia malayi can infect both humans and animals. However, the trend of infected cats with Brugia spp. was increasing. Filarial control measures should be strongly launched continuously.
