Introduction Onchocerciasis, or ‘river-blindness’, is a disease caused by infection with the filarial worm, Onchocerca volvulus. The parasite is transmitted to human hosts by infected female ‘blackflies’, Simulium spp., as they feed on the host’s blood. Whilst feeding, the fly secretes saliva containing infective larvae. These larvae enter the host’s subcutaneous tissue, migrate, and form nodul...

We present a case of mixed infection by two filariae (Loa loa and Mansonella perstans). It seems that the infection was suspected due to a pronounced eosinophilia in a routine analysis. Sheathed and unsheathed microfilariae were observed in the spread of peripheral blood, which enabled a diagnosis to be established of mixed infection by filariae. The definitive diagnosis of the species was carr...

Abstract Background Bancroftian filariasis remains endemic in Fiji despite >10 years of mass drug administration (MDA) using diethylcarbamazine and albendazole (DA). The addition ivermectin to this combination (IDA) has improved efficacy microfilarial clearance at 12 months individually randomized trials nocturnal transmission settings, but impact a setting diurnally subperiodic filarial...

A study was conducted to determine the susceptibility of local strains of Culex quinquefasciatus and Aedes aegypti to infection with the strain of Wuchereria bancrofti that occurs in Maceió. State of Alagoas, Brazil. Cx. quinquefasciatus blood fed simultaneously on the same microfilariae carrier ingested more blood and 2-3x more microfilariae than Ae. aegypti. Survival rates of both species of ...

Dirofilariosis caused by the Dirofilaria repens nematodes is widely dispersed in southern Europe, Asia and Africa among dogs, cats, other carnivores and occasionally, humans. The first case of D. repens infection, found in Poland in 2007, concerned humans. In 2009, dirofilariosis was first registered in dogs in 3 focuses in central Poland, Warsaw, Pruszków and Zyrardów, whose range grew conside...

Basophils play a key role in the development and effector phases of type 2 immune responses in both allergic diseases and helminth infections. This study shows that basophils become less responsive to IgE-mediated stimulation when mice are chronically infected with Litomosoides sigmodontis, a filarial nematode, and Schistosoma mansoni, a blood fluke. Although excretory/secretory products from m...

Microfilarial periodic pattern of Wuchereria bancrofti in Kenya was confirmed by the statistical method proposed by Aikat and Das (1977). Fifteen microfilarial positive individuals were brought to Nairobi from Malindi, which is one of the filariasis foci on the coastal area of Kenya. From each individual a 60-microliter finger prick blood film was made every 2 hours throughout one complete 24-h...

this study was performed to determine the prevalence of canine parvovirus (cpv) in dogs referred to veterinary hospital of ahvaz, khouzestan province, iran. fecal samples were collected from 78 diarrheic dogs between 2005 and 2007. the dogs were divided into two age groups (< 6 months and > 6 months), four different breeds (terriers, germanshepherds, doberman pinschers and mixed) and another tw...
