Gut microbial composition differs among FUNAAB Alpha broiler chicken genotypes raised in a tropical environment. Microb Pathog 2025; 198:107126. [PMID: 39551110 DOI: 10.1016/j.micpath.2024.107126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Revised: 11/06/2024] [Accepted: 11/14/2024] [Indexed: 11/19/2024]
Abstract
The gut microbiota of FUNAAB Alpha chickens plays a crucial role in determining their overall health and performance. Understanding the various types and diversity of microbiota in the gut of different genotypes of chickens is crucial for enhancing their well-being, productivity, and disease resistance. This study employed 16S rRNA and metagenomics analysis to examine the gut bacteria of three genotypes of FUNAAB Alpha broiler chickens, namely Naked neck, Frizzle, and Normal feather. There were three phyla observed in the three genotypes: Bacteroidetes, Actinobacteria, and Firmicutes. Through the utilisation of 16S rRNA sequencing, we successfully identified and categorised the various microbiota present within the gastrointestinal tract. Our study revealed notable variations in the composition and quantity of microbiota across the three genotypes, suggesting that each genotype possesses a distinct collection of gut bacteria. A wide range of microbiological diversity was observed within the community. Interestingly, the Normal feather chicken exhibited a greater number of operational taxonomic units (OTUs) compared to the Naked neck and Frizzle feather chicken. This study presents significant findings regarding the ceacal microbiota of FUNAAB Alpha chickens, emphasising the variations observed among different genotypes. It is crucial to study composition-modification techniques to enhance host health and performance, as well as to control zoonotic pathogens that can contaminate poultry products and threaten consumers' health.

Abstract
Diclazuril (DIC) is a broad-spectrum anti-coccidiosis drug of the triazine class, widely used in poultry farming. The overuse of DIC may lead to its accumulation in animal bodies, which may enter the food chain and threaten human health. In this work, we fabricated a stable Eu3+-doped UiO-66 fluorescence sensor (EuUHIPA-30) for the sensitive detection of DIC. Among 20 veterinary drugs, the fluorescence of EuUHIPA-30 selectively responds to DIC, with a low detection limit (0.19 μM) and fast response (10 s). EuUHIPA-30 is recyclable and can detect DIC in chicken and eggs with good recoveries. Moreover, a smartphone-integrated paper-based sensor enables the instrument-free, rapid, visual, and intelligent detection of DIC in chickens and eggs. This work provides a promising candidate for practical fluorescent DIC sensing in animal-derived food to promote food safety.

Abstract
Poultry cecum microbes are dynamic and complex. They play important roles in disease prevention, detoxification of harmful substances, nutrient processing, and ingestion harvesting. It may be possible to increase poultry productivity by better understanding and controlling the microbial population. We analyzed the composition and function of Nigerian hens' cecal microbiota using high-throughput sequencing methods. Using high-throughput sequencing of the 16S rRNA genes (V1-V9) hypervariable regions, the cecal microbiota of three Nigerian indigenous chicken genotypes (Naked neck, Frizzle, and Normal feather) was described and compared. A total of two phyla were represented among the three genotypes (Firmicutes and Proteobacteria). Microbiological diversity was found in the community, with naked neck having the most evenness, followed by normal feather, which had the least. There were a lot of similarities between the naked neck and frizzle feather chicken groups when it came to genetic diversity between them. For example, the bacterial cecal microbiota of the naked neck chickens was more diverse, with a higher concentration of motility proteins, two-component systems, bacterial secretion systems, and the formation and breakdown of secondary metabolites. More understanding on gut microbiota roles and interactions will help Nigerian poultry farmers improve their methods and give valuable data for the study of bacteria in the chicken gut.

Abstract
<p>Coccidiosis is a major disease caused by various <em>Eimeria</em> species in rabbits. The aim of the present study was to investigate the haematological and pathological changes in rabbits infected with <em>E. magna</em>. Moreover, the localisation of coccidial antigens was examined in the intestines of rabbits with two kinds of serum as primary antibodies. In the present study, forty-five 28-day-old weaned rabbits were randomly divided into three groups and reared in three separate places. Group A was infected with 20×10<sup>3</sup> sporulated oocysts of <em>E. magna</em>, group B was only used to produce anti-<em>E. intestinalis</em> serum by infecting them with 3×10<sup>3</sup> sporulated oocysts of <em>E. intestinalis</em>, and group C was designated as the control group. According to histopathological evaluation of group A, the epithelial cells of the jejunum and ileum were parasitised with a large number of oocysts and other stages of <em>E. magna</em>. The haematological results showed that red blood cell counts, haemoglobin counts, haematocrit levels and the percentage of lymphocytes were significantly decreased in group A compared with group C (<em>P</em><0.01), but white blood cell counts and the percentage of neutrophils were significantly increased (<em>P</em><0.01). The weight of group A began to decrease on the 5<sup>th</sup> day after infection, and this decrease continued until the 9th day. Immunohistochemistry staining revealed that two kinds of coccidial antigens were basically located at the same sites of the intestine when anti-<em>E. intestinalis</em> serum and anti-<em>E. magna</em> serum were used as primary antibodies. Most likely, <em>E. magna</em> and <em>E. intestinalis</em> antigens have some similar antigenic determinants; this finding provides a theoretical basis for screening for common antigens of these two coccidian species.</p>

Abstract
Newcastle disease and heat stress reduce the productivity of local chickens of Nigeria (LCN). This study compared the antibody response to Newcastle disease and heat tolerance among different LCN genotypes in hot humid tropics using multivariate discriminant analysis. A total of 299 birds were used for the study. Geometric mean titre against Newcastle disease before vaccination (GMTB), geometric mean titre against Newcastle disease after vaccination (GMTA), rectal temperature at week 4 (RT4), pulse rate at week 4 (PR4), respiratory rate at week 4 (RR4), heat stress index at week 4 (H4), rectal temperature at week 13 (RT13), pulse rate at week 13 (PR13), respiratory rate at week 13 (RR13) and heat stress index at week 13 (H13) were measured. All the traits were significantly (p < 0.05) affected by the genotype while sex differences were only observed in GMTB, GMTA and RR13. The stepwise discriminant analysis revealed RR4, PR13, RT13, H4, GMTA, GMTB, H13 and RT4 to be effective in differentiating the three chicken genotypes. Two canonical variables that accounted for 60.21% and 39.79% of the total variation were revealed. Linear discriminant functions for differentiation of the three chicken genotypes were also developed. 87.39% of normal feather, 76.58% of naked neck and 100% of frizzle feather chickens were correctly assigned into their genotypes. The longest Mahalanobis distance was observed between normal feather and frizzle feather chickens. The discriminant functions developed in this study could be used to differentiate the three genotypes of LCN using antibody response to Newcastle disease and heat tolerance.

Abstract
Coccidiosis is an antagonistic poultry disease which negatively impacts animal welfare and productivity. The disease is caused by an obligate, intracellular protozoon known as Eimeria. Several Eimeria species known to infect chickens have been well documented. However, recent studies have elucidated the emergence of three novel genetic variants or operational taxonomic units (OTUs). The discovery of OTUx, OTUy and OTUz complicates the identification and diagnosis of coccidiosis. OTUs are clusters of unknown or uncultivated organisms that are grouped according to a similarity in DNA sequence to a set of specific gene markers. OTUs have been reported in the Earth's Southern Hemisphere, including Australia, Venezuela, India, Zambia, Uganda, Tanzania, China and Ghana. Elucidating their impact on the poultry industry is fundamental in preventing anticoccidial resistance and to access the potential of OTUs as vaccine candidates to provide cross-protection against similar Eimeria species. The identification of OTUs further decreases the risk of false negative coccidial diagnosis. Therefore, this article reviews the importance and risk imposed by OTUs, coupled with their prevalence and geographical distribution in chickens globally.
