this research aims  to monitor the trace elements content (cr, cu, pb, cd, ag, al, mn, mg, zn and fe) in the tissues of the muscle and liver of silver carp (h. molitrix ) and stone moroko (p. parva) from zarivar wetland in western iran. this research was cross-sectional. the research specimen  was fish caught from zarivar wetland. metal concentration analysis was carried out utilizing an  icp. ...

The development of sensitive surveillance technologies using PCR-based detection of microbial DNA, such as the reverse line blot assay, can facilitate the gathering of epidemiological information on tick-borne diseases, which continue to hamper the productivity of livestock in many parts of Africa and elsewhere. We have employed a reverse line blot assay to detect the prevalence of tick-borne p...

INTRODUCTION East Coast fever, a devastating disease of cattle, can be controlled partially by vaccination with live T. parva sporozoites. The antigens responsible for conferring immunity are not fully characterized. Recently it was shown that the P. falciparum immunodominant protein UB05 is highly conserved in T. parva, the causative agent of East Coast fever. The aim of the present investigat...

Lymphocyte homeostasis is regulated by mechanisms that control lymphocyte proliferation and apoptosis. Activation-induced cell death is mediated by the expression of death ligands and receptors, which, when triggered, activate an apoptotic cascade. Bovine T cells transformed by the intracellular parasite Theileria parva proliferate in an uncontrolled manner and undergo clonal expansion. They co...

An infection and treatment protocol is used to vaccinate cattle against Theileria parva infection. Due to incomplete cross-protection between different parasite isolates, a mixture of three isolates, termed the Muguga cocktail, is used for vaccination. While vaccination of cattle in some regions provides high levels of protection, some animals are not protected against challenge with buffalo-de...

Fish assemblages inhabiting the Taizi River basin have been severely degraded by anthropogenic disturbances, which weaken basin’s ecological function and limited revitalization of northeast industrial base. Long-term rehabilitation has conducted to restore fish fauna improve habitat conditions. To explore distribution patterns key factors after this rehabilitation, a comprehensive detailed surv...

-1. Paramyosins isolated from nematode Caenorhabditis elegans, clam Meretrix meretrix and Mercenaria mercenaria, scallop Patinopecten yessoensis, abalone Notohaliotis discus, lobster Homarus vulgaris and sea cucumber Holothuria leucospilata were examined for phosphorylation rate and immunological reactivity against anti-Meretrix ~t-paramyosin antiserum. 2. A high phosphorylation was only observ...

Procedures for impact assessment, including “beyond-BACI” (before–after control–impact) and proportional differences (ratios between impact and control treatments) were used to test population replenishment of marine invertebrates at a marine conservation area (MCA) and three fished (control) areas in the Solomon Islands of the southwestern tropical Pacific. Within shallow reef terrace habitat,...
