“…Control of poultry coccidiosis is presently based on managerial skills and the use of prophylactic coccidiostatic drugs (Tewari and Maharana, 2011). It is a ubiquitous intestinal protozoan infection of poultry seriously impairing the growth and feed utilization of infected animals.…”

The present study is undertaken to compare the efficacy of alcoholic extracts of Black Peppers (Piper nigrum ) and Chutra leaves (Urtica dioica ) with a patent drug Esb3 against coccidiosis in chicken. 16 Fayoumi breed chickens were collected from a local farm and divided into four groups; A, B, C and D, each consisting of four chickens, Group A (control), Group B (alcoholic extracts of Black Peppers @ 9ml/kg bd wt.), Group C (alcoholic extracts of Chutra leaves @ 9ml/kg bd wt.) and Group D ( Esb3 @ 1 ml/ liter drinking water). All the treated chickens were kept under close observation for 18 days and data was collected at 3 days interval. In group B, two chickens died within 4-7 days of treatment and in group C one chicken died on 5th day of medication. All the chickens of control group died within 5-7 days of medication. Oocyst was counted for per gram of feces in all groups. Biochemical parameters like SGPT and haematological parameters like Total erythrocyte count (TEC), Haemoglobin count (Hb), Packed cell volume (PCV), Erythrocyte sedimentation rate (ESR) were determined. There were significant decrease in oocyst count in group B and C in compared to control and very few oocysts were present in faeces of 6 days onward of medication. All the chickens were survived in group D and oocyst started to disappear in the faeces from 3rd day onward of medication. Our study suggests Both Black Peppers and Chutra are effective against coccidiosis in chicken and Chutra is more effective than Black peppers.Res. Agric., Livest. Fish.2(1): 117-124, April 2015

“…They have developmental cycles with an exogenous phase in the environment and an endogenous phase in the intestine of chickens [3]. The efforts to prevent this disease have been focused on developing vaccines and drugs with coccidiostatic and coccidicidal activity [4]. So far, genomic studies have revealed the wide antigenic variability of species such as Eimeria tenella, one of the most pathogenic parasites to chickens, which leads to develop a vaccine resistance rapidly [1].…”

The control of avian coccidiosis since the 1940s has been associated with the use of ionophores and chemical drugs. Recently, a significant interest in natural sources has developed due to the pressure to poultry industry to produce drug-free birds. Consequently, the search of products derived from plants and other natural sources has increased in the last years. Today, many commercial products containing essential oils, extracts, and other compounds are available. The use of these compounds of natural origin is related to an increased immune response, a body weight gain, destruction of oocyst, among other benefits. The main inconvenience of these products is the act on some species of Eimeria, but not all. This genetic variability found in the parasite makes the use of products difficult to control and treat coccidiosis. In this chapter, several proposals of treatment are presented based on the use of natural products, considering the new strategies of treatment with minimal consequences to birds.

“…This infection is mostly asymptomatic and the response raised by the immune system pushes the parasite to differentiate into a slowly dividing, encysted form that persists for the life span of its host (Innes, 2010). Two other parasites of the phylum, Eimeria and Theileria spp., can cause economic losses affecting poultry and cattle, respectively (Bishop et al, 2004;Tewari and Maharana, 2011).…”

Emerging roles for protein S-palmitoylation in Toxoplasma biology

a b s t r a c tPost-translational modifications are refined, rapidly responsive and powerful ways to modulate protein function. Among post-translational modifications, acylation is now emerging as a widespread modification exploited by eukaryotes, bacteria and viruses to control biological processes. Protein palmitoylation involves the attachment of palmitic acid, also known as hexadecanoic acid, to cysteine residues of integral and peripheral membrane proteins and increases their affinity for membranes. Importantly, similar to phosphorylation, palmitoylation is reversible and is becoming recognised as instrumental for the regulation of protein function by modulating protein interactions, stability, folding, trafficking and signalling. Palmitoylation appears to play a central role in the biology of the Apicomplexa, regulating critical processes such as host cell invasion which is vital for parasite survival and dissemination. The recent identification of over 400 palmitoylated proteins in Plasmodium falciparum erythrocytic stages illustrates the broad spread and impact of this modification on parasite biology. The main enzymes responsible for protein palmitoylation are multi-membrane protein S-acyl transferases harbouring a catalytic Asp-HisHis-Cys (DHHC) motif. A global functional analysis of the repertoire of protein S-acyl transferases in Toxoplasma gondii and Plasmodium berghei has recently been performed. The essential nature of some of these enzymes illustrates the key roles played by this post-translational modification in the corresponding substrates implicated in fundamental processes such as parasite motility and organelle biogenesis. Toward a better understanding of the depalmitoylation event, a protein with palmitoyl protein thioesterase activity has been identified in T. gondii. TgPPT1/TgASH1 is the main target of specific acyl protein thioesterase inhibitors but is dispensable for parasite survival, suggesting the implication of other genes in depalmitoylation. Palmitoylation/depalmitoylation cycles are now emerging as potential novel regulatory networks and T. gondii represents a superb model organism in which to explore their significance.
