Haemosporidian Parasites in Domestic and Wild Birds

Isra’a M. Essa — 2025-02-19

This study aims to provide brief information about the role of haemosporidian parasites in birds and significant implications for avian health, population dynamics, and control efforts. Haemosporidian parasites, belonging to the phylum Apicomplexa, are a diverse group of protozoan organisms that infect a wide range of vertebrate hosts, including birds. These parasites have a complex life cycle, with both sexual and asexual stages, and are transmitted by blood-feeding insects such as mosquitoes, midges, and blackflies. The potential impact of these parasites include a wide range of health issues in infected birds, including anemia, decreased body condition, and reduced reproductive success. Additionally, the distribution of parasitic populations within individual hosts can lead to complex interactions between the host and its parasites, which can influence the overall population structure and dynamics of both the host and the parasite. The prevalence and genetic diversity of haemosporidian parasites can also vary depending on various factors, such as the migratory patterns of birds, availability of suitable vectors, and environmental conditions in different regions. In conclusion, haemosporidian parasites play a crucial role in the dynamics of bird populations, influencing their health, fitness, and population structure. Understanding the complex interactions between these parasites and their avian hosts is essential for developing effective strategies for the conservation and management of bird populations.

Duaa R.M. Al-Safi — 2025-03-15

Antioxidants and lipid markers have gained significant attention in recent decades for their pivotal role in promoting overall health and well-being. On other hand, the improper disposal of industrial effluents has emerged as a major environmental challenge leading to contamination of water sources that subsequently impact public health. Estimation of the effect of contaminated water by the residents of brick kilns on the level of antioxidants (CAT, GPX, and SOD), lipid peroxidation MDA, and lipid profile (TC, HDL, LDL, and TG). A total of 30 surface water samples were collected from the areas near the brick kilns located in Al-Hai, Al-Kut, and Badra cities into labeled plastic containers. Then, overall 60 rats were divided equally into two groups; the 1st was given tap water (negative control), and the 2nd was given the contaminated water (experimental). After 75 days, blood was collected from all animals to obtain the sera that tested using the specific species quantitative enzyme-linked sorbent assay (ELISA) kits to measure the concentration of antioxidants, lipid peroxidation and lipid profile. In comparison to values of control group, results of antioxidants including CAT (5.419 ± 0.363 pg/ml), GPX (24.533 ± 1.317 IU/ml) and SOD (4.013 ± 0.479 U/ml) were reduced significantly; while significant increases were shown in results of lipid peroxidation MDA (187.333 ± 10.402 ng/ml), as well as in LDL (641.611 ± 54.809 ng/ml). However, insignificant variation between the values of experimental and control groups was seen in values of TC (3.528 ± 0.332 nmol/ml), HDL (36.283 ± 1.881 ng/ml), and TG (567.556 ± 72.724 ng/ml).

Septiani Septiani — 2025-04-22

Processing potatoes into flour is one way to reduce the risk of damage and extend the shelf life of potatoes. Potato flour has high absorption, fine texture, sweet taste, and a distinctive fragrant aroma. Cookies are dry baked goods produced by baking dough made from wheat flour, either with or without substitutes, along with oil or fat, and optionally incorporating other food ingredients and approved additives. Based on this, it is necessary to conduct research on potato flour formulations in cookies with organoleptic tests to determine the best formulation for making cookies from potato peel flour, obtaining the best formulation it can reduce the dependence of the community and industry on the use of wheat flour. The research used a Completely Randomized Design (CRD) with four formulations (0%, 25%, 50%, and 75% potato peel flour substitution) and two repetitions. Organoleptic testing, including hedonic and hedonic quality assessments, was conducted to evaluate panellists' preferences for colour, texture, taste, and aroma. The results showed that cookies with 25% potato peel flour substitution (F1) were the most preferred, achieving the highest scores in all sensory attributes. However, increasing the substitution level resulted in a darker colour, firmer texture, and a more pronounced bitter taste, affecting overall acceptability.
