Polymerase chain reaction (PCR) amplification provides a powerful tool for parasite detection. This chapter examines the use of PCR to diagnose malaria in patients with low parasite densities (submicroscopic infections, SMI) and also occult loaiosis (OL: Loa loa infection without detectable circulating microfilaria on standard microscopy). It provides therefore the issue of management of these ...

CASE REPORT We present a case of ocular loiasis with a subconjunctival filaria, 5.5cm long, and a severe microfilaremia, 1 microfilaria/ml, on a previously asymptomatic woman from Equatorial Guinea, with a past medical history of hypereosinophilia of unknown origin. DISCUSSION Ocular loiasis is an imported infestation with a very low rate in our country. Nevertheless, chronic infestation in i...

Dirofilaria immitis is a filariid worm which typically lives as adult in the right ventricle of the heart and the pulmonary arteries of the dog, causing the canine heartworm disease. Therapy of canine dirofilariosis due to Dirofilaria immitis is indicated for dogs suffering from clinical signs of the disease (such as chronic cough). The present paper describes diagnostic and treatment features ...

In order to clarify the genetic differences between Onchocerca dewittei japonica, the causative agent of zoonotic onchocerciasis in Japan and a related undescribed Onchocerca sp., both parasitizing wild boar (Sus scrofa) of which the infective larval stages are indistinguishable from each other, we compared the sequences of the mitochondrial cytochrome c oxidase subunit 1 (CO1) gene region from...

The status of Dirofilaria immitis infection was assessed in pet dogs of Busan, Korea, and chemoprophylactic effects of microfilaricidal medication were evaluated. A total of 294 pet dogs older than 6 mo were examined, 217 of which had been maintained indoors, and 77 had been kept outdoors. The SnapR kit and direct microscopic examinations of the peripheral blood were used. The mean overall para...

Abstract. Hanafiah M, Athaillah F, Helmi TZ, Sutriana A. 2023. Morphology of Setaria spp. (Setariidae; Nematoda) in Aceh cattle, Indonesia. Biodiversitas 24: 4151-4160. filaria usually inhabit the peritoneal cavity and its microfilaria can be found cattle blood. Adult worms are considered non-pathogenic but may cause mild fibrinous peritonitis. However, serious conditions. The migrate randomly ...

Ivermectin treatment was evaluated for its efficacy and side reactions in sixty patients of Orissa with Bancroftian filarial infection and microfilaremia. Ivermectin was administered as a single oral dose at four dosage levels (20, 50, 100 and 200 micrograms/kg), and both microfilarial clearance and associated side reactions were monitored in a double blind fashion. Blood microfilariae were cle...

Filariae of animals, especially those of mammals, often infect humans and typically produce cryptic infections. These "zoonotic" infections have been reported from virtually all parts of the world including temperate zones. Infections may be symptomatic or not, and the parasites are found in surgical tissue biopsy specimens or, more rarely, are removed intact from superficial sites such as the ...
