The available data is scanty about Egyptian water buffalo lips, cheeks, and palate.The current investigation was focused on describing the morphology of the lip, cheek, and palate.Our study included the gross, light, and electron microscopic examinations of ten heads of the Egyptian water buffalos.The nasolabial plate surface carried numerous scales of keratinized epithelium. Internal labial surface and labial mucocutaneous junctions were covered with stratified squamous keratinized epithelium. Two types of hair follicles in the dermis included ordinary and cavernous types characterized by cavernous space. The conical papillae on the internal aspect of the oral commissure were projected from the mucous membrane. Seromucous glands were occasionally observed under the oral mucous membrane of the commissure and gave positive PAS and AB. Conical papillae density on the inner cheek surface had some variations: the rostral part had large papillae, while the dorsal part had numerous papillae than the ventral part, the caudal part had a smaller number of papillae, while the middle part was devoid of papillae. Parotid duct opening in the buccal vestibule was without papillae. Conical papillae had two surfaces; the rostral surface was highly keratinized than the caudal one. The buccal gland was a compound tubuloacinar mixed (mucoserous) gland and mucus acini only reacted to PAS and AB. The oral surface of palatine rugae was covered with highly keratinized epithelium than the aboral surface. Palatine glands showed PAS and AB positive.The result describes the relationship between the available food particles, environmental conditions and the lip, cheek, and palate appearance, and structure.

Gut Bacterial Flora of Open Nested Honeybee, Apis florea

Frontiers in Ecology and Evolution (2022)

D. N. Ganeshprasad Jafar K. Lone Kunal Jani Yogesh S. Shouche Khalid Ali Khan

Honeybees are eusocial insects with close interaction with their surrounding environment. Gut microbiota in honeybees play a significant role in host health, biology, and interaction behavior with the surrounding environment. Apis florea , a wild bee, is the most primitive among all honeybees and is indigenous to the Indian subcontinent. Previous reports on reared honeybee species provide information on the gut microbiome. No such studies are reported on the gut microbiota of the wild honeybee species. This study aimed at studying the gut microbiome of the wild honeybee species, A. florea . The study reports the analysis and the identification of gut bacteria in the wild honeybee species, A. florea , employing culture-based and culture-independent methods. Cultured bacteria were identified and characterized by MALDI-TOF MS and 16S rRNA sequencing. A comprehensive analysis and identification of non-culturable bacteria were performed by 16S rRNA amplicon next-generation sequencing. This approach splits gut bacteria into four bacterial phyla, four families, and 10 genera in major. The dominant taxa identified in A. florea belonged to the family Enterobacteriaceae (79.47%), Lactobacillaceae (12.75%), Oxalobacteraceae (7.45%), and Nocardiaceae (0.13%). The prevailing bacteria belonged to Enterobacter, Lactobacillus, Escherichia-Shigella, Massilia, Klebsiella, Citrobacter, Pantoea, Serratia, Rhodococcus , and Morganella genera, belonging to phyla Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidetes. This study observed the occurrence of a few bacteria that are not previously reported for their occurrence in other species of the Apis genus, making this investigation highly relevant with regard to the bee microbiome.

Pineal Gland Plays a Role in Gonadal Development after Eyelids Separation in Puppies La Glándula Pineal Juega un Rol en el Desarrollo Gonadal Luego de la Separación de los Párpados en Cachorros

Khalil Abou-Easa Mohammed A. El‐Magd Ehab Tousson Amin Hassanin Mustafa Shukry

ABOU-EASA, K.; EL-MAGD, M. A.; TOUSSON, E; HASSANIN, A.; SHUKRY, M. & SALAMA, M. Pineal gland plays a role ingonadal development after eyelids separation in puppies. Int. J. Morphol., 33(1):7-18, 2015.SUMMARY: Several functional and morphological studies have been conducted on the pineal gland in many mammalianspecies; however, no published reports are available on the role of pineal gland on the gonadal development before and after eyelidsseparation in puppies. Therefore, this study aimed to trace the postnatal histo-morphological changes in the pineal gland and gonads ofpuppies before (2, 10 and 11 days old) and after (25, 35 and 40 days old) eyelids separation in an attempt to investigate the p ossible roleof pineal gland on the gonadal development. In general, the differentiation of pineal cells, interstitial endocrine cells of te stes and stromalovarian cells coincides with the start of eyelids separation in puppies. Histological examination of stained pineal and gonadal slices ofpuppies after eyelids separation revealed a remarkable differentiation of pinealocytes and testicular interstitial endocrine ce lls, as well aspresence of some evidence of folliculogenesis in ovary. Surprisingly, melatonin receptor (MT1) protein expression levels were s ignificantlyincreased in the ovaries and testes of puppies after eyelids separation. Moreover, the mRNA and protein expression of AANAT, a rate-limiting enzyme in melatonin biosynthesis, was notably increased in the pineal gland of opened eyes puppies. Our results suggest anincrease of melatonin production from the pineal gland of opened eyes puppies and this could play a vital role in the developmentalchanges observed in the gonads of these puppies.KEY WORDS: Pineal; Testis; Ovary; Puppy; Eyelids separation.

Effect of dietary incorporation of peanut and linseed meals with or without enzyme mixture on physiological performance of broilers

Saudi Journal of Biological Sciences (2022)

Ahmed A. Saleh Amin Nahla Khairy A. Amber Nemeet Badawi Salama Mostafa Aboelenin

The present study aimed to evaluate the impact of feeding peanut meal and linseed meal (LSM) with or without enzyme mixture on growth, plasma metabolites, muscle amino acid (AA) profile, nutrient digestibility, and expression of nutrient absorption-related genes in broilers. A total of 560 one-day-old Cobb-500 male broiler chicks were distributed into eight experimental treatments (7 replications of 10 chicks each) as follows: This study was designed by using 560 one-day-old Cobb-500 male broiler chicks were distributed into eight experimental groups (7 replications of 10 chicks each) to evaluate the differences in body weight, body weight gain, feed intake, feed conversion rate, carcass parts, blood biochemical and mRNA expression genes. Group 1 (C) control fed the basal diet without supplements, Group 2 (C + E) is control group fed on 350 g/ton enzyme mixture, Group 3 (C + PNM100) is control group fed 100 kg/ton peanut meal, Group 4 (C + E + PNM100) is a control group fed on 350 g/ton enzyme mixture and 100 kg/ton peanut meal, Group 5 (C + LSM100) is a control group fed on 100 kg/ton linseed meal, Group 6 (C + E + LSM100) is a control group fed on 350 g/ton enzyme mixture and 100 kg/ton linseed meal, Group 7 (C + PNM50 + LSM50) is control group fed on 50 kg/ton peanut meal and 50 kg/ton linseed meal. Group 8 (C + E + PNM50 + LSM50) is the control group fed on 50 kg/ton peanut meal and 50 kg/ton linseed meal. Each gram of the enzyme mixture contains 11,000 U Xylanase, 6000 U Cellulase, 700 U β-Mannanase, 1500 U Phytase, 5 mg α-Amylase, and 2 mg Protease. No differences in Bodyweight, Bodyweight gain, Feed intake, and carcass parts were noticed among experimental groups, while abdominal fat (%) and FCR were reduced (P < 0.05) in PNM50 + LSM50 + E and LSM100 groups. Plasma metabolites were not altered except total cholesterol, triglyceride, and LDL, reduced (P < 0.01) in treated birds. Dietary inclusion of 100 kg PNM or LSM reduced (P < 0.05) methionine concentration in muscle, while all remaining AA and ammonia concentrations were unaffected. Hepatic MDA contents were reduced (P < 0.001) in treated groups. Nutrient digestibility was not altered among groups except for protein digestibility, which was elevated (P < 0.05) in PNM50 + LSM50 + E, E, and PNM100 + E groups. The highest mRNA expressions of PepT1, APN, SGLT1, HMGCR, GHr, and IGF-1 genes were noticed in PNM50 + LSM50 + E. Conclusively, PNM and LSM can efficiently substitute corn and soybean meal in broiler diets, particularly when fortified with exogenous enzymes, without negative impacts on broiler performance.

Impacts of sex steroids and aromatase inhibitor on performances, carcass characteristics and gonadal histology of broiler chickens slaughtered at different ages

Reproduction in Domestic Animals (2022)

Mona Younis Fatima S. Alaryani Fatima A. Jaber Asmaa Aboelnour Mustafa Shukry

This experiment was established to evaluate the influence of synthetic steroid hormone and aromatase inhibitor on performance, carcass characteristics, hormonal profile and gonadal structure of broiler chickens slaughtered at two different ages. A total of 360 Cobb Avian48 chicks were sexed and distributed randomly into three groups: Tam10 group; birds received Tamoxifen10mg (Tamfen 10 mg@ ) orally at a level of 10 mg/kg body weight daily from the 3rd till the 9th day of age; BOL group: birds injected intramuscularly with Boldenone undecylenate (BOLD-GAN@ 0.1 mg/kg) at the 5th and the 9th day of age; and Control group. BOL injection or Tam supplementation improved performance traits compared with the control group. Although Tam positive effect appeared early before the 5th week of age, the BOL effect was delayed to the 6th week. BOL injection improved carcass characteristics of both sexes at both 5 and 6 weeks slaughtering ages. Regardless of treatment effect, the mortality% was higher in the late weeks of age than in the early weeks. Moreover, BOL treatment increased comb% compared with control and Tam treatments. Generally, males had significantly higher testosterone levels and lower oestrogen levels than females. Males treated with Boldenone had the highest testosterone level, although testosterone levels did not differ considerably among females of the various groups. BOL treatment females had the lowest oestrogen level. Both Tam10 and Boldenone had adverse effects on testicular and ovarian histology, affecting the typical structures. Finally, we concluded that the anabolic effect of Tam10 may be achieved in griller broilers production without changing the sex hormones assay. Although Boldenone achieved an anabolic effect without changing blood sex hormone levels, this effect is induced early with females and delayed with males, which prolongs the marketing period. The goal is to shorten this period. Therefore, this material can only be used with the possibility of separating females from males to be used with females only.

Structural and functional adaptation of the lingual papillae of the Egyptian fruit bat (Rousettus aegyptiacus): specific adaptive feeding strategies

Folia Morphologica (2021)

Ramadan M. Kandyel Mohamed M. A. Abumandour Samy F. Mahmoud Mustafa Shukry Naglaa Madkour

The current investigation was aimed to clarify the correlations between the feeding strategy and lingual structure of the Egyptian fruit bat captured from the Egyptian east desert.The current work was performed on 12 adult Egyptian fruit bats that were observed grossly and with the help of the stereo, light, and scanning electron microscope. There were three types of the lingual papillae: one mechanical (filiform) and two gustatory (fungiform and circumvallate).There were seven subtypes of filiform papillae recognised on the seven lingual regions. There were few fungiform papillae distributed among the filiform papillae on the lingual tip and two lateral parts of apex and body while fungiform papillae were completely absent in the median part. There were three circumvallate papillae. The central bulb of circumvallate papillae was surrounded by one layer of two segmented circular pad. The lingual tip had cornflower-like and diamond-shaped filiform papillae.Histochemical results revealed that the lingual glands showed a stronger Alcian Blue (AB)-positive reaction and gave dark blue colour, while the reaction for the periodic acid-Schiff (PAS)-stain was negative. Also, the glands exhibited a blue colour as an indication of positive AB reactivity with combined AB-PAS staining.
