Show more [+] Less [-]The influence of high and low doses of acrylamide on porcine erythropoiesis
2020
Snarska Anna | Palus Katarzyna | Wysocka Dominika | Rytel Liliana
Due to the widespread occurrence of acrylamide in the environment, its likely carcinogen status, and the suitability of the pig model as a human analogue, the authors decided to evaluate the impact of high and low doses of this compound on the processes of erythropoiesis in swine bone marrow.

2020
Zhang Shi-Jun | Wang Lu-Lu | Lu Shi-Ying | Hu Pan | Li Yan-Song | Zhang Ying | Chang Heng-Zhen | Zhai Fei-Fei | Liu Zeng-Shan | Li Zhao-Hui | Ren Hong-Lin
The plate counting method widely used at present to discern viable from non-viable Brucella in the host or cell is time-consuming and laborious. Therefore, it is necessary to establish a rapid, simple method for detecting and counting viable Brucella organisms.

2020
Sabri Abdul Rahman Mohammad | Khairani Bejo Siti | Zakaria Zunita | Hassan Latiffah | Azri Roslan Mohd
Leptospirosis is a bacterial disease that affects both humans and animals, the occurrence of which increases markedly during and after heavy rainfall and flooding. The aim of this study was to determine the serological prevalence of leptospiral infection in livestock after a voluminous flood in 10 districts of the Malaysian state of Kelantan.

2020
Díaz Carlos | Celer Vladimír | Frébort Ivo
Swine DNA viruses have developed unique mechanisms for evasion of the host immune system, infection and DNA replication, and finally, construction and release of new viral particles. This article reviews four classes of DNA viruses affecting swine: porcine circoviruses, African swine fever virus, porcine parvoviruses, and pseudorabies virus. Porcine circoviruses belonging to the Circoviridae family are small single-stranded DNA viruses causing different diseases in swine including poly-weaning multisystemic wasting syndrome, porcine dermatitis and nephropathy syndrome, and porcine respiratory disease complex. African swine fever virus, the only member of the Asfivirus genus in the Asfarviridae family, is a large double-stranded DNA virus and for its propensity to cause high mortality, it is currently considered the most dangerous virus in the pig industry. Porcine parvoviruses are small single-stranded DNA viruses belonging to the Parvoviridae family that cause reproductive failure in pregnant gilts. Pseudorabies virus, or suid herpesvirus 1, is a large double-stranded DNA virus belonging to the Herpesviridae family and Alphaherpesvirinae subfamily. Recent findings including general as well as genetic classification, virus structure, clinical syndromes and the host immune system responses and vaccine protection are described for all four swine DNA virus classes.

This study determined the presence of nitric oxide synthesis isoforms (nNOS, iNOS, and eNOS) in thoracic spinal cord segments and nodose ganglia of rats with gamma-irradiated livers.

The purpose of this study was to determine the effects of vitamin C supplementation on blood oxidative stress biomarkers and antibody response to vaccination in calves.
Show more [+] Less [-]Effect of Nano-hydroxyapatite as an Alternative to Inorganic Dicalcium Phosphate on Growth Performance, Carcass Traits, and Calcium and Phosphorus Metabolism of Broiler Chickens
2020
Basant Mohsen Sobhi | Esam Yousef Ismael | Ahmed Sadek Mansour | Mabrouk Elsabagh | Khaled Nasr El-din Fahmy
The influence of nano-hydroxyapatite (NHA) as a source of calcium (Ca) and phosphorous (P) alternative to inorganic dicalcium phosphate (DCP) on the performance, carcass traits, and the Ca and P contents in serum, bone, and excreta was evaluated in broiler chickens. One-day-old un-sexed Arbor Acres Plus broiler chickens (n.= 160) were randomly assigned to four treatment groups of four replicates with 10 birds in each replicate.

2020
Kotb, M. M. A1 | Ragab, G. A.2 | Fathy, M. Z .2 | Haggag, U.2 | Nesreen. M. Safwat3
The objective of the present study was to evaluate the ability of estrogen to promote induced tibial fracture healing in a rat model. The study was conducted on 14 albino rats divided into two equal groups (seven rats in each group). The first group considered as a control group. The second group was injected estradiol solution 0.1 mg/kg into the fracture gap. The progress of healing in each group was evaluated by clinical, radiography, ultrasonography and pathological examinations. The healing process was observed to be superior in the estrogen group compared to the control one. Estrogen was found to promote healing of injured bone and is suggested to be used in cases of complicated or delayed bone fracture.

2020
M. Nayel | A. El-Sify | S. Akram | M. Allaam | E. Abdeen | H. Hassan
In this study multiplex PCR was used for typing of Clostridium perfringens isolates from soil, clinically healthy and diseased sheep. Clostridium perfringens was isolated from 41 out of 100 soil samples, 12 out of 100 clinically healthy sheep and 118 out of 200 sheep with enterotoxaemia signs. Genotyping of 41 isolates from soil indicated that 29 (70.73%) were type A, 3 (7.31%) were type B and 9 (21.95%) were type D. Of 12 isolates from clinically healthy sheep 6 (50%) were type A and 6(50%) were type D. Of 118 isolates from diseased sheep 42 (35.59%) were type A, 22 (18.64%) were type B and 54 (45.76%) were type D. This result indicates that Clostridium perfringens type A, B and D are the main types causing enterotoxaemia in sheep in Egypt and Clostridium perfringens type A must be included in any vaccine programme to ensure optimum protection.
