Neurocysticercosis (NCC) has attained the importance of one of the most common cause of focal brain lesions in patients infected with HIV (human immunodeficiency virus). Adequate data regarding the rate of this co-infection is lacking. Therefore, the present study was carried out to determine the prevalence of cysticercosis among HIV patients residing in Puducherry or its neighboring districts ...

Background and Aim: Recent information on the occurrence of bovine hypodermosis in Kazakhstan is limited to results a few clinical studies northern eastern regions. A first serological study aimed obtain more data its geographical distribution estimate prevalence this country. Materials Methods: Serum samples collected from 891 dairy cows 30 farms eight Kazakh provinces during winter season 201...

Diagnosis of larval migrans (LM) is usually done by immunodiagnostic methods. These methods, however, simply show the presence or absence of antibody but not the active infection of the patients. Therefore, we aimed to establish a diagnostic method for detecting circulating Toxocara canis antigen using a sandwich, ELISA. Monoclonal antibodies (MAb) were produced against the excretory-secretory ...

The evolutionary causes of variation in host specialization among phytophagous insects are still not well understood and identifying them is a central task in insect /host plant biology. Here we examine host utilization of the chrysomelid beetle Oreina elongata that shows interpopulation variation in the degree of specialization. We focus on larval behaviour and on what selection pressures may ...

A monoclonal antibody 2F7.C7 which identifies an epidermal antigen common to both anuran and urodele amphibia is described. This antigen has a high molecular weight and is expressed at stage 12 1/2 first inside and then on the surface of epidermal cells. It is not expressed on presumptive nervous tissue. It is expressed on all cells of the larval epidermis including ciliated and nonciliated cel...

Mice have been used to the study the mechanisms of protective innate and adaptive immunity to larval Strongyloides stercoralis. During primary infection, neutrophils and eosinophils are attracted by parasite components and kill the larvae by release of granule products. Eosinophils also function as antigen-presenting cells for the induction of a Th2 response. B cells produce both IgM and IgG th...

Because diagnosis of strongyloidiasis by stool examination is unreliable and because of the potential for serious disease in Strongyloides infections, there is need for improved diagnostic aids to facilitate recognition and treatment of this parasitic infection. Serologic testing, when available, requires antigen preparation from infected primates or dogs that can be difficult to maintain. Seve...

For most of the family Porcellanidae, which comprises 283 species, larval development remains to be described. Full development has been only described for 52 species, while part of the larval cycle has been described for 45 species. The importance of knowing the complete larval development of a species goes beyond allowing the identification of larval specimens collected in the plankton. Morph...

Genetic loci that influence behavior are often difficult to identify and localize in part due to the quantitative nature of behavioral phenotypes. Previous studies had found an association between pupal lethality and altered larval behavior for mutants of several genes. To facilitate the identification and localization of new mutants that influence larval foraging (movement in the presence of f...

Using the rate of development of blowflies colonising a corpse, accumulated degree hours (ADH), or days (ADD), is an established method used by forensic entomologists to estimate the post-mortem interval (PMI). Derived from laboratory experiments, their application to field situations needs care. This study examines the effect of the post-feeding larval dispersal time on the ADH and therefore t...
