stool examinations of 402 inhabitants of 8 villages in and around an area near zahedan, and 280 people who had emigrated from the rural area of zabol, revealed the following: the prevalence of infection with ascaris, trichuris and trichostrongylus was very low (less than 5%) in all areas surveyed, while the mean infection rates found for h.nana, hookworm and e.vermicularis (by stool examination...

Hookworms infect several hundred million people worldwide, causing malnutrition, anemia, and growth retardation. Infections generally result in a strong type 2 immune response, but the effector mechanisms that mediate worm expulsion remain poorly characterized. In this study, we determined the role of mast cells and basophils in protective immunity against the murine hookworm, Nippostrongylus B...

This study was conducted to investigate the susceptibility of 4 strains (AKR, CF#l, C3H/He and KK) of inbred mice to infection with Schistosoma japonicum. The worm recovery was highest in KK strain (50%), followed by C3H/He (42%) , AKR (42%) and CF #1(38 %) respectively. The worm burden of the females of strain KK was significantly higher than that of the males. The worm maturity was highest in...

Worm is the major hurdle, which restricts the comfortable communication in any networks. Worm is a malicious software program that destroys the normal communication in the networking systems. Every system must not be vulnerable to avoid infection by worm in the computing networks. Defending against such worm still plays vital role to the network programmers. Various countermeasures have been ta...

When dogs were immunized with soluble extract of adult Ancylostoma ceylanicum antigen, they were partially resistant to challenge infection in this model of human hookworm infection. Two immunizing doses, each of 1 mg protein suspended in Freund's complete adjuvant, were administered to one group of animals 1 and 3 weeks prior to infection with 5000 larvae. When compared with control dogs given...

The study was conducted to explore the effect of two herbal drugs, Caesalpinia crista and Nigella sativa in comparison with Oxfendazole in broilers experimentally induced with Ascaridia galli infection .A total of 130 day old broiler chicks were divided into five groups i.e. A, B, C, D and E each group having 26 birds. Group E was kept as negative control, while all other groups were induced wi...

Infectious pathogens can selectively stimulate activation or suppression of T cells to facilitate their survival within humans. In this study we demonstrate that the trematode parasite Schistosoma mansoni has evolved with two distinct mechanisms to suppress T cell activation. During the initial 4- to 12-wk acute stages of a worm infection both CD4(+) and CD8(+) T cells are anergized. In contras...

The role of vitamin A was evaluated for its chemotherapeutic and chemoprophylactic action against Acanthocheilonema viteae infection in Mastomys coucha. Vitamin A was administered for 10 days, five days before infection and five days post infection. On day 0 experimental animals as well as controls were infected with L3, the infective stage. Establishment of the worms revealed significantly les...

School attendance records of all primary schools in a guinea worm-endemic village in southwestern Nigeria were examined to determine the cause of missed school days and school drop-outs. At the time of the survey, 1,495 pupils (768 boys and 727 girls were registered in the 4 primary schools in the village, of which 21% of the pupils were infected with guinea worm disease (GWD). Female pupils ha...

STUDY DESIGN Antimicrobial effect of a novel silver-impregnated pedicle screw in rabbits. OBJECTIVE A novel spine implant model was designed to study the antimicrobial effect of a modified Titanium (Ti) pedicle screws with methicillin-resistant Staphylococcus aureus (MRSA) in multiple surgical sites in the lumbar spine of a rabbit. SUMMARY OF BACKGROUND DATA Infection in spinal implant is o...
