Brugia pahangi

Brugia pahangi have been found in cats in Malaysia, Thailand, and Indonesia.[2] A large population of cats, more specifically stray cats, are infected with the parasite. When the nematode was first being studied, a report by Mak et al. (1980) reported that 11% of cats sampled in the Peninsular Malaysia were infected. In Thailand, 25% of the blood samples take from 83 cats residing in Buddhist temples carried the worm (Palmieri et al., 1985).[3]

The size is approximately 280 μm long by 5–6 μm wide. The cephalic tip is bluntly rounded. The nerve ring (excretory pore) and the nucleus of the excretory cell are said to be similar to B. malayi. Behind the nerve ring it was found that the cells of the nuclear column over time become less dense. The central viscus (Innenkorper) begin around the middle of the body, the body nuclei are scatter which causes trouble in experiments the reason being that it is difficult to stain. There are four rectal cells ("G" or "R" cells), R₁ is the most prominent of the rectal cells, and it is about four-fifths of the body width. The anal spot is V-shaped. The nucleus is around 3 μm in diameter.[1] Females are about 38 to 63 mm long.[4] This genus of Brugia is most commonly recognized by the spicules in males, which are needle like mating structures that open the vulva of the female worm.

In the Brugia genus, there are two spicules, they are the shortest in length, the left one being 200–215 μm and the right one 75–90 μm long. Despite the fact that males have certain characteristics that help key this species out, the females lack those key characteristics. However, according to [5] In an experiment done by Knott, 2% of the nematodes he collected had microfilaria that was about 280 μm long.

To find if the cat is infected or not, a blood test is taken. To measure the severity of the infection, the number of microfilariae per microliter of blood is tested.[7]
