“…As described in many studies on birds, this study clearly confirmed a decrease in albumin and the A/G ratio in inflammatory diseases in all six species ( 14 , 28 , 29 ). The results by group show that the greater the severity, the more pronounced the decrease.…”

“…In particular, C-reactive protein (CRP) in dogs and serum amyloid A (SAA) in cats have been routinely tested in small animal clinics as measurement kits have been commercialized. Known avian APPs include SAA, alpha-1 acid glycoprotein, ceruloplasmin, transferrin, fibrinogen, and haptoglobin (8)(9)(10)(11)(12)(13)(14)(15). Among these avian APPs, SAA has been the focus of research because it is a precursor of the amyloid A (AA) protein.…”

Rescued wild birds have very high rates of inflammatory diseases; however, there have been limitations in assessing them sensitively. Few studies have examined acute-phase proteins in wild birds. In this study, serum amyloid A (SAA) was evaluated as an inflammatory indicator along with traditional indices such as white blood cell count, albumin, and albumin/globulin ratio. In total, 291 samples from 139 birds of six avian species were analyzed. All samples were divided into four groups (severe, moderate, mild injuries, and clinically healthy) based on clinical examinations and evaluated by group. SAA levels were measured using an anti-chicken SAA ELISA kit and compared with leukocyte counts, albumin concentrations, and albumin/globulin ratios. Differences among groups were evaluated using the Kruskal–Wallis test, followed by a post hoc test using Dunn’s multiple comparisons with SPSS V27. Statistical significance was set at a value of p of <0.05. The median concentration and interquartile range (ng/mL) of SAA in each group were 78.10 ng/mL (50.71–109.30), 31.15 ng/mL (19.85–49.24), 9.68 ng/mL (4.71–22.06), and 3.10 ng/mL (1.50–6.00). We observed a significant difference in the mean levels between the groups (p < 0.001), with the same results observed across species. All four indices showed significant differences in mean values between the groups (p < 0.001). In addition, SAA showed rapid changes in periodically collected samples, reflecting either a positive treatment response or the onset of subclinical diseases. SAA can be used to detect inflammatory conditions and asymptomatic disease in wild birds and is helpful in accurately identifying current health status, which is essential for successful treatment and release.

“…Similarly, if leukocytes are infected, the host immune system might face some difficulties identifying a pathogen and mounting an immune response against it. However, the host inflammatory response to parasitic infections is much more complex than that and assumptions should be carefully developed [ 52 , 53 , 54 ].…”

Host Cells of Leucocytozoon (Haemosporida, Leucocytozoidae) Gametocytes, with Remarks on the Phylogenetic Importance of This Character

et al. 2023

Leucocytozoon parasites remain poorly investigated in comparison to other haemosporidians. The host cell inhabited by their blood stages (gametocytes) remains insufficiently known. This study aimed to determine the blood cells inhabited by Leucocytozoon gametocytes in different species of Passeriformes and to test if this feature has a phylogenetic importance. We microscopically analyzed blood films stained with Giemsa from six different bird species and individuals and used PCR-based methods for parasite lineage identification. The DNA sequences obtained were applied for phylogenetic analysis. Leucocytozoon parasite from the song thrush Turdus philomelos (cytochrome b lineage STUR1), the blackbird Turdus merula (undetermined lineage), the garden warbler Sylvia borin (unknown lineage) inhabited erythrocytes, a parasite from the blue tit Cyanistes caeruleus (PARUS4) infects lymphocytes, while in the wood warbler Phylloscopus sibilatrix (WW6) and the common chiffchaff Phylloscopus collybita (AFR205) they were found inhabiting thrombocytes. Parasites infecting thrombocytes were closely related, while the parasites infecting erythrocytes were placed in three different clades, and the one found in lymphocytes was placed in a separate clade. This shows that the determination of host cells inhabited by Leucocytozoon parasites can be phylogenetically important and should be considered in future species descriptions. Noteworthy, phylogenetic analysis might be used for the prediction of which host cells parasite lineages might inhabit.

“…Serum GLb level was indicator of the immune function and protein metabolism of the poultry, 19.00% CP significantly increased the serum GLb of hens compared to 14.00% CP (Poosuwan et al 2010), in our study, 19.00% CP also induced the serum GLb concentration in peacock. However, the serum GLb concentration in peacock fed with 20.00% CP was normal, indicating irrational CP might lead to chronic or acute inflammatory reaction (Walton & Siegel, 2022). Egg production was controlled by the development of ovarian follicles, which in turn were regulated by reproductive hormones, including LH, FSH and E 2 (Wilson, 1978;Wang & Johnson, 1993).…”

In Experiment one, a total of 60 blue peacocks were randomly assigned into the control group (12.00 MJ/kg) and treatment group (12.30 MJ/kg). Each group consisted of three repeats and each replicate contained 10 peacocks (2 males and 8 females). In Experiment two, based on better metabolic energy (ME) (12.30 MJ/kg), 90 blue peacocks were randomly assigned to three dietary treatments with 18.00%, 19.00% and 20.00% crude protein (CP) levels. The results of Experiment one revealed that the different dietary ME levels had minor effect on productive performance of peacocks (p>0.05). Decreasing dietary ME levels decreased the concentration of estradiol (E 2 ) and increased the concentrations of follicle stimulating hormone (FSH) and luteinizing hormone (LH) (p<0.01). However, 12.00 MJ/kg ME stimulated creatinine levels of blue peacock, which exceeded normal values. Based on this result, blue peacocks fed with 12.30 MJ/kg ME had better performance. Results from Experiment two indicated that egg production of blue peacocks was significantly improved by the 20.00% CP diet. The concentrations of FSH, LH, and E 2 remained at high levels fed with the 20.00% CP diet. Changes in serum biochemical indices such as total cholesterol, creatinine and globulin of peacocks supplied with 18.00% and 19.00% CP diets were abnormal (p<0.05). Based on the results of two experiments, the optimal dietary ME and CP levels of blue peacocks were 12.30 MJ/kg ME and 20.00% CP.
