Summary: “Maternally derived multivalent recombinant vaccines show potential as transmission-blocking vaccines against mixed infection of Eimeria. The specific antibodies can sustain for 11 weeks and be transferred to hatchlings through maternal immunization. Vaccinated chickens exhibit higher survival rates, body weight gains, reduced lesion scores, and decreased oocyst excretion compared to unvaccinated chickens when challenged with mixed Eimeria infection.”

Summary: The effects of eight plant extracts and essential oils, as well as their mixture, on the pathogenic parasite Eimeria tenella were investigated. Both in vitro and in vivo studies showed that these extracts and essential oils inhibited the invasion of Eimeria tenella and improved the symptoms of coccidial infection. They have potential as anticoccidial agents.

Summary: Understanding the molecular basis of the determinants of tissue tropism among Eimeria parasites, this study revealed the crucial roles of microneme protein (MIC) and its associated microneme adhesive repeat (MAR) domain in governing the site-specific development of E. acervuline, E. maxima, and E. mitis within their hosts.

Summary: Infections by apicomplexan parasites involve interactions with host proteins such as SAGs and SRS. The SAG family of Eimeria tenella, a parasite causing coccidiosis in chickens, shares a conserved three-layer alpha beta alpha fold with the CAP superfamily. Despite differences in structure, Eimeria SAG and Toxoplasma SRS families exhibit sequence hypervariable hotspots on their surfaces, suggesting a common purpose of providing a platform for sequence variability.

Summary: This study aimed to determine the effect of Eimeria parasite infection on the luminal and mucosal microbiota of the duodenum and jejunum in broiler chickens. Through 16S rRNA amplicon sequencing, it was found that there were differences in microbiota diversity between infected and control birds, with the infection affecting mucosal microbiota in the longer term and jejunal microbiota in the shorter term. Additionally, the relative abundances of bacteria known for short-chain fatty acid (SCFA) production were lower in infected birds, potentially impacting SCFA production. These findings contribute to a better understanding of the impact of Eimeria infection on chicken gut microbiota.

Summary: This study describes the genetic diversity of Eimeria acervulina populations in Africa and Europe using PCR-RFLP analysis. The results show high levels of haplotype diversity, with different countries having different PCR-RFLP haplotypes. This variability may pose challenges for anticoccidial drugs and future subunit vaccines.

Summary: This pilot study evaluated the concentration of prostaglandin GF2 alpha and isoprostane 8-iso-PGF2 alpha in plasma and intestine of SPF Leghorn chickens challenged with Eimeria maxima, with or without dietary supplementation of curcumin. The results indicated that curcumin supplementation reduced the levels of oxidative damage and lipid oxidation products in the intestine after Eimeria maxima challenge. Additional studies in broiler chickens are needed to confirm and expand on these findings.

Summary: Avian coccidiosis caused by genus Eimeria leads to significant economic losses in the global poultry industry, emphasizing the need for cost-effective recombinant vaccines. Studies on genetic diversity of potential vaccine candidates like MIC2 and SAG1 show different patterns in field isolates from countries such as China and India. Monitoring genetic heterogeneity and evolutionary aspects in more E. tenella isolates from different regions is crucial for designing effective coccidial vaccines.

Summary: The severity of white striping in chicken breasts affects the chemical composition and texture, which in turn has some impact on the quality of chicken nuggets and hamburgers. Severe white striping increases fat and collagen content, lipid oxidation, cooking loss, and yellow intensity in chicken breasts. However, the presence of white striping does not significantly affect the production and quality of chicken nuggets and hamburgers.

Summary: This study investigated the impact of temperature, storage time, and relative humidity on egg quality indicators, with temperature being identified as the most crucial environmental factor. Principal Component Analysis revealed that most quality indexes are similar, except for the eggshell percentage which represents an exterior quality indicator. An artificial neural network with one hidden layer and four neurons accurately predicted the Yolk index, showing promise as a tool for evaluating egg quality.

Summary: This study aimed to investigate the effects of adding Ilex paraguariensis residue (IPPR) to the basal diet of laying hens on bird health, production, fatty acids, egg quality, and transfer of chlorogenic acids to the egg. The results showed that IPPR did not affect egg production and feed conversion, but led to an increase in chlorogenic acids in the egg yolks and a reduction in total bacterial count in the feces and eggshells. Additionally, IPPR intake resulted in lower levels of saturated fatty acids and higher levels of monounsaturated fatty acids.

Summary: This study investigated the effects of adding industrial egg residue (IER) to broiler feed on digestibility and performance. Results showed that IER, which has high concentrations of calcium and crude protein, can fully replace limestone in broiler diets. There were no significant differences in performance and meat yield between the treatments, and the inclusion of IER also led to a decrease in abdominal fat percentage.

Summary: The high mortality rate caused by parasitic worms on their hosts is a major concern. Current drugs on the market are often toxic with numerous side effects, necessitating the search for new, more potent molecules. Medicinal plants have been found to contain a wide range of novel molecules that can effectively combat different types of helminths. This review provides an overview of the methods, activities, and mechanisms of action of cyclic peptides, specifically cyclotides, for treating helminthic infections.
