BACKGROUND The knowledge of the current prevalence of lymphatic filariasis and its transmission will be helpful in its elimination. Thus, the present study is aimed to determine its prevalence among hydrocele patients which is a common presentation in chronically infected cases. MATERIALS AND METHODS One hundred patients suffering from hydrocele admitted to the surgical ward were included in ...

Ultrastructure of microfilaria Brugia malayi was investigated with electron microscope. Microfilariae are covered by a sheath membrane with dense materials on its outer surfaces. The cuticle consists of 3 layers; namely, external cortical, internal cortical and fibrous layer. Beneath these cuticular layers, thin hypodermis is present and the muscle cells are arranged of 4 groups in a crosssecti...

This study was conducted to investigate the low prevalence of Dirofilaria immitis in dogs in Johor Bahru as reported by veterinary practitioners, using wet blood mount, Knott’s Concentration Test and two heartworm antigen test kits (IDEXX Canine SNAP® 4Dx and RapiGEN®). This study also compared the two test kits used and determined the microfilaria species. Blood were collected from 100 owned d...

The parasites of genera Haemoproteus, Plasmodium, and Leucocytozoon are well-known avian haematozoa and can cause declined productivity and high mortality in wild birds. The objective of the study was to record the prevalence of haematozoan parasites in a wide range of wetland birds in Bangladesh. Six species of Haemoproteus, seven species of Plasmodium, one unidentified species of Leucocytozoo...

Filaria can be present for several years before symptoms develop, or they may be of a nonpathogenic type. In these cases the microfilaria may be found incidentally as in the present cases. The complement fixation test is positive in up to 50 per cent of the cases of filariasis but is negative in pure Acanthocheilonema perstans infection. This test is of value in confirming a diagnosis of tropic...

Canine and feline heartworm diagnostic, treatment and prevention strategies have changed during the previous decade. We experienced an unprecedented increase in the numbers and kinds of available medications and diagnostic aids, and also in the capabilities of pet owners to acquire information. This can be both beneficial and detrimental in our efforts to establish and maintain effective strate...

Glutamate-gated chloride channels (GluCl) are targets for avermectin/milbemycin (A/M) anthelmintics such as ivermectin that cause paralysis of somatic and pharyngeal muscles in gastrointestinal nematodes. Ivermectin is useful for onchocerciasis control programs because of its activity against microfilariae that often cause ocular disease and severe dermatitis. However, mechanisms responsible fo...

Epidemiological and entomological surveys were carried out in the human and mosquito populations in Maceió, Alagoas, in order to assess the present status of bancroftian lymphatic filariasis. Examination of thick blood smears of 10,450 students from different areas of the city revealed 0.66% Wuchereria bancrofti microfilaria carriers. The distribution of filariasis is focal in the city, 80% of ...

A total of 534 psittacine and passerine birds consisting of 241 imported and 293 local birds were examined histologically. As a result, the following parasites were found: Giardia (86 cases), Knemido-coptes (26 cases), coccidia (10 cases), Ascaridia (6 cases), Cryptosporidium (5 cases), Sarcocystis (5 cases), tapeworm (4 cases), microfilaria (2 cases), Hexamita (1 case), and Spiroptera (1 case)...

OBJECTIVE The present study investigates the prevalence of onchocerciasis in 40 communities of the LGA and provides data, which could contribute towards the control programme of the disease in the local government Area, Edo state, Nigeria. METHODS A physician performed the skin examination and thereafter a skin biopsy taken and immersed in normal saline solution in the wells of micro titratio...
