Abstract Helminth infection conditions lung macrophages in the long term, but little is known about how helminths affect macrophage responses to respiratory viral coinfection. Experimental helminth of BALB/c and C57BL/6 mice revealed an increased type 2 airway inflammation that was associated with pronounced phenotypic changes macrophages. These consist a disappearance reaction SiglecF+ alveola...

A system was developed to identify and quantify up to seven species of helminth eggs (Ascaris lumbricoides -fertile and unfertile eggs-, Trichuris trichiura, Toxocara canis, Taenia saginata, Hymenolepis nana, Hymenolepis diminuta, and Schistosoma mansoni) in wastewater using different image processing tools and pattern recognition algorithms. The system was developed in three stages. Version on...

BACKGROUND Helminth infections can negatively affect the immunologic host control, which may increase the risk of progression from latent Mycobacterium tuberculosis infection to tuberculosis (TB) disease and alter the clinical presentation of TB. We assessed the prevalence and determined the clinical relevance of helminth co-infection among TB patients and household contact controls in urban Ta...

Helminth infection provides a unique challenge to the host immune system. Not only are helminths complex multicellular organisms, but they have intricate life cycles with multiple developmental stages, several of which may coexist in the infected host. In most cases, the host response to helminth infection is characterized by eosinophilia, increased serum immunoglobulin (Ig) E and IgG4, and mas...

One cestode and eight nematode species were collected from 30 badgers, Taxidea taxus, from Kansas and West Texas. These included Mesocestoides corti Hoeppli, 1925 (23% of hosts infected), Filaroides milksi Whitlock, 1956(7%), Filaria taxideae Keppner, 1970(33%), Metathelazia capsulata Gerichter, 1948 (47%), Physaloptera torquata Leidy, 1886 (100%), Molineus sp. (37%), Ancylostoma taxideae Kalka...

A total of 267 rural scavenging chickens were examined from October 1998 to August 1999 in four woredas (districts) of the Amhara Region, Ethiopia. Of these chickens, 243 (91.01%) were found to harbour one to nine different helminth parasites and 24 (8.99%) were free of helminth parasites. A significant difference (P < 0.01) was found between the prevalence rates of helminth parasites in the di...

In this paper, we analyse the distributional patterns of adult helminth parasites of freshwater fishes with respect to the main hydrological basins of Mexico. We use the taxonomic distinctness and the variation in taxonomic distinctness to explore patterns of parasite diversity and how these patterns change between zoogeographical regions. We address questions about the factors that determine t...

BACKGROUND Understanding the prevalence of soil-transmitted helminth infections is necessary to plan control strategies and focus on highly endemic regions for preventive chemotherapy and improved sanitation facilities. India is known to be endemic for soil-transmitted helminth infections. METHODS To understand the prevalence, spatial distribution and identify high-risk zones, a systematic se...

Characterisation of protective helminth acquired immunity in humans or experimental models has focused on effector responses with little work conducted on memory responses. Here we show for the first time, that human helminth infection is associated with altered proportions of the CD4+ memory T cells, with an associated alteration of T(H)1 responses. The reduced CD4+ memory T cell proportions a...

This study was performed  in second half of year 2009.For bird counting , monthly from Septamber until March 2009. Total counted birds in Maroon lake were (971). Maximum number of counted birds was in February  (191) and minimum of counted was in Septamber (95). Total counted birds in Jaizan were (385. Maximum number of the counted bird was in February (84) and minimum of counted (52) was in Ja...
