BACKGROUND It has been hypothesized that helminth infections increase HIV susceptibility by enhancing systemic immune activation and hence contribute to elevated HIV-1 transmission in sub-Saharan Africa. OBJECTIVE To study systemic immune activation and HIV-1 co-receptor expression in relation to different helminth infections and in response to helminth treatment. METHODS HIV-negative adult...

background: the aim of the study was assessment of defaults and conducted meta-analysis of the efficacy of single-dose oral albendazole against t. trichiura infection. methods: we searched pubmed, isi web of science, science direct, the cochrane central register of controlled trials, and who library databases between 1983 and 2014. data from 13 clinical trial ar­ticles were used. each article w...

Ticks and tick-borne diseases, including theileriosis, constitute a major constraint to livestock production. Two species, known as Theileria lestoquardi and Theileria ovis, are suspected to contribute to ovine theileriosis in Iran. However, the epidemiological aspects of ovine theileriosis are poorly understood in this country. In a survey, designed to identify Theileria species in sheep, 52 (...

This was the first molecular study of the bacterial flora of the sheep scab mite (Psoroptes ovis). A sequence analysis of genes coding for 16S rRNA revealed that Serratia marcescens and bacteria closely related to Staphylococcus intermedius or Staphylococcus chromogens and Alloiococcus otitidis were present. These bacteria were associated with skin lesions, dermatitis, and otitis media caused b...

The effects of mesothermic anaerobic or aerobic sludge digestion on survival of eggs from the roundworms Ascaris suum, toxocara canis, Trichuris vulpis, and Trichuris suis and from the rat tapeworm Hymenolepis diminuta were studied. Destruction of eggs throughout a 15-day treatment period, as well as their viabilities after reisolation, was analyzed. The laboratory model digesters used in this ...

Experiments were performed with BALB/c mice to elucidate the roles of humoral and cell-mediated immune responses in the acquisition of protective immunity to Brucella ovis and to compare infection immunity with immunity developed through vaccination with a hot saline extract (HS) of B. ovis. Mice convalescing from a primary infection with B. ovis displayed a high level of resistance to reinfect...

While the incidence ofmany parasitic diseases has decreased because of the development of anthelmintics and environmental hygiene, infection by Trichuris still occurs. This parasite exhibits some special parasitological and clinical features. Beaver et al introduced the term visceral larva migrans in the case of toxocariasis.' While the visceral larva migrans syndrome has been reported to be ca...

The genes coding for the five outer membrane proteins (OMPs) of the Omp25/Omp31 family expected to be located in the outer membrane (OM) of rough virulent Brucella ovis PA were inactivated to evaluate their role in virulence and OM properties. The OM properties of the mutant strains and of the mutants complemented with the corresponding wild-type genes were analyzed, in comparison with the pare...

We present results of the paleoparasitological analysis of Cervidae coprolites that were recovered from the archaeological site Furna do Estrago, Pernambuco, Brazil. Trichuris sp. eggs were recovered from the coprolite samples dated 1,040 ± 50 years before present. This is the first record of Trichuris sp. in semiarid Cervidae, unexpectedly recorded in archaeological material.
