A coronavirus is a group of enclosed single RNA viruses that infected mankind and animals, CoVs are members of the Coronavirinae subfamily, caused by a strain known as SARS-Cov-2 which consider a pandemic disease around the world .several clinical studies are Reaves that SARS-Cov-2 with SARS-Cov shares many biological characteristic features. These zoonotic viruses can enter the cell system initiated by binding of viral spike protein to the Angiotensin-converting enzyme (ACE-2). Most severe coronavirus infections in human beings have been associated with a specific disease, such as hypertension, diabetes mellitus, and cardiac disease. Extensive research has revealed the association between this virus and the appearance of cardiovascular diseases like (myocarditis, coronary syndrome, myocardial injury, and thromboembolism). In this review, we summarized the virus replication, Potential Transmission, pathological observation in animales virus, its effects on the cardiovascular system, and Coronavirus zoonosis  

  According to their accessibility and lower cost-effectiveness when compared to synthetic chemical treatments, medicinal wild plants and herbs have been used for ages as beneficial tools in the management of many diseases. The popular medicinal plant Vitex agnus-castus, which is indigenous to the Mediterranean region and widely distributed in Europe, Asia, and North Africa, is used to treat a number of conditions and diseases, including premenstrual syndrome, mastalgia, infertility, and menstrual cycle management. The current study examined how the aqueous extract of the vitex plant compared to clomiphene citrate in female rabbits. In this experiment, nine female rabbits were divided into three equal groups.  Aqueous vitex plant extract was administered to the first group for 15 days, clomiphene citrate was administered to the second group for 5 days as aspect of an approved course of treatment, and distilled water was administered to the third group for 15 days as a control. To determine the impact of the aqueous extract of Vitex agnus castus on the functions of the female rabbits' body organs, the complete blood count (CBC) and GLU, UREA and CREA were calculated. In addition, the analyses of blood picture showed a significant disparity, enzymes; even histopathology results in compare with control which showed a significant decreasing in WBC count has observed in the vitex extract (F) group that was 4.7 for WBC and 4.45 for RBC while 9.8 for HGB. On the other hands, decreasing of WBC count observed significantly in the clomiphene citrate (C) group that was 3.9 for WBC and 5.3 for RBC while HGB was 6.4mg.

Bacteria is the main cause of the genital disorder. Abortion, recurrent abortion and placenta retention are the main disorder accompanying with pregnancy failure. The current study aimed to find the relationship between this disorder and Campylobacter infection and main Campylobacter species related to this disorder. For this purpose, 50 aborted fetuses and vaginal swabs were collected. Case history and multiplex PCR were applied. The result showed that Campylobacter detected at a rate 26% in abortion cases and 61.5% of positive cases of campylobacter spp. are accompanied by placenta retention. The current study revealed that 75% of positive cases of campylobacter spp. accompany with recurrent abortion. According to MPCR test, Campylobacter fetus, Campylobacter jejuni, and Campylobacter coli were detected in a rate of 86.65%, 12.3%, and 0%, respectively.

Entamoeba histolytica is a parasitic protozoan that caused amoebiasis or amoebic dysentery, it is an intestinal disease which infects colon and liver Amoebic dysentery is spread all over the world. E. histolytica is causing the death of human cells and leading to develop invasion, and ulceration of the intestine. However, amebic liver abscess (ALA) considers as major common extraintestinal disease caused by E. histolytica. The current study was designed to estimate the effect of E. histolytica trophozoite on liver functions through the evaluation of some bio-chemical parameters for patients with amebiasis. Blood sample were collected from patients with amoebic dysentery after diagnosed about 100 from stool sample from them microscopically and detected by PCR technique to confirm the infection with am-amebiasis, all sample with amoebiasis were subjected to biochemical study after the separation of serum. Biochemical parameters that included during this study were AST, ALT and ALP. Lipid profile included Triglyceride and Cholesterol as well as some minerals like   Iron, Zinc, and Potassium. The results for the level of AST and ALT were showed a high significant difference (P<0.01) where AST was (22.84+/-7.83) in patients’ compared with (55.36+/-16.8) in control groups and ALT level   Was (20.4+/- 9.37) in patients compared with (47+/-20.1) in control groups. Additionally, there is no significant difference (p>0.05) in ALP level where it was (351.7+/-235.2) in patients with amoebic dysentery compared with (336. 13+/-204.08) in controls group. Triglyceride were also checked in patients with amoebic dysentery and the results showed that a significant difference (p<0.05) between (166.72+/-62.4) in patients and (135. 43+/-45.2) in control groups. Cholesterol level was also checked in patients and the results showed there is no significant difference (P>0.05) between (185.8+/-77.2) in patients and (160.19+/-51.3) in controls groups. In addition, some minerals  were studied during the following study like  Iron,  Zinc, and Potassium for patients with and the results were not showed a significant difference (P>0.05) in zinc, potassium and iron where  the level of iron were ( 85.24+/-16.58) in patients compared with ( 81.22+/-15.5) in control groups, while the level of zinc were (108.09+/-24.4) in patients and ( 101.76+/-24.4) in control groups , the level of potassium were (3.73+/-1.89) in patients and compared with ( 3.84+/-1.14) in control groups.

  The current study was designed to assess some critical mineral elements concentration in the serum of camels using advanced methods like Energy Dispersive Spectroscopy analysis (SEM-EDS) using scanning electron microscope of minute camel’s blood. The present study was conducted on forty-eight healthy adult males and females of camel (Camelus dromedarius) aged three to five years in three southern governorates of Iraq: Basra, Thi-Qar and Muthana (6 males and 10 females per governorate). Blood samples were applied to field emission scanning electron microscopy (FE-SEM) to recognize the essential cellular morphological properties found in camel’s RBCs that assist camels to adaptation on harsh condition. While, serum was subsequently assayed for elemental analysis by energy dispersive spectroscopy (EDS). The SEM images of RBCs showed a smooth surface with a circumference invagination referred to tropical waist with difference in length and width of RBCs between male and female. While, EDS percentage atomic concentrations study of camel’s serum revealed different amount of essential, heavy and rare trace elements in both sexes from the Basra and Thiqar governorate and different levels in essential elements in the serum of both sexes of Thiqar and Muthana governorates.  

A total of twenty-six local chickens were representing shank feathering and non-feathering shank were used to sequence five QTLs, which associated with shank feather trait in chicken. The five location sequence results were shown polymorphism between the shank feathering and non-feathering shank. All the candidate markers were differed between the shank feather and non-feathering shank. The big distance was in (ADL221), and the less distance was in marker MCW315.

     The current study aimed to evaluate the effects of oral administration of spirulina (as a food supplement) on the reproductive performance of adult female rabbits. Female rabbits (16 to 18 weeks old) were divided into three groups (10 rabbits/ group). These groups are: (Gr.I) as a control group and (Gr. II) spirulina was given at a dose (0.5 g / kg of body weight) and (Gr. III) was given a complex of folic acid, B6 and B12 (2.5 + 50 +1 mg / kg body weight) all groups were treated for four weeks. At the end of the treatment period, 2 untreated males (two males/ group) were naturally mated with treated females. The results showed that there was no significant difference in the estrogen concentrations among all groups, while the progesterone concentration showed a significant decrease in the third compound group compared to the control group and DXN-spr. Also, the testosterone hormones did not show significant differences in all groups. FSH and LH concentrations appeared to be significantly decreased in the third group than in the other two groups. The fertility rate and the number of female fertilities increased in the second group (DXN-Spr.) compared to the other groups. There was also a significant increase in birth weight and fertility rate in this group compared to the control and group No. 3 groups. We conclude that oral dosed spirulina (0.5 g/kg body weight) acts as a natural antioxidant that improves reproductive efficiency and reproductive hormones.  

Kinesio taping (KT) is a technique extrapolated from human physiotherapy consisting of the application of an elastic tape to the skin to trigger analgesic, muscular, postural correction and circulatory effects. It is an easily applicable technique that has been developed in the field of equine physiotherapy over the last decade. The objective of this research is to evaluate the analgesic effect of KT applied to spinous processes of the horse measuring mechanical nociceptive threshold (MNT). KT was applied on 5 spinous processes of 15 horses, in two different experiments, comprising KT with 50% tension (KTT) and KT with no tension (KTNT). Measurements were taken before application of the tape (M0), 60 minutes after (M1) and 24 hours after, following its removal (M2). Clinical assessment of sensitivity to palpation was conducted at M0 and M2. Outcomes obtained at M0 were compared to those obtained at M1 and M2, and between both tests (KTT-KTNT). A significant increase in the MNTs at M1 was observed in both tests but not maintained following its removal 24 hours later. Sensitivity to palpation decreased in practically all the spinous processes in both tests. No significant changes were observed in the comparative analysis between both tests. KT applied to spinous processes of the horse with and without tension causes an increase in the MNTs 60 minutes after application. This effect is not sustained following taping removal although there is a clinically significant decrease of the sensitivity to palpation of the spinous processes.

This study aimed to characterize the different Staphylococci recovered from mastitic cows and buffaloes. A total of 126 mastitis milk samples were aseptically collected from clinically mastitic animals including 87 cows and 39 buffaloes. Bacteriological examination and biochemical identification using VITEK-2-compact-SYSTEM revealed that a total of 94 Staphylococcus isolates (74.6%) were recovered; 56 isolates (59.6%) and 38 isolates (40%) from cows and buffaloes, respectively. S. aureus was the most predominant isolate (n=26; 15 from cows and 11 from buffaloes) with a percentage of 27.7%. Moreover, 68 coagulase-negative staphylococci (CNS) isolates (72.3%) were identified of which; 21 S. epidermidis (22.3%); all isolates were from cattle, followed by 18 S. lentus (19.1%); 8 and 10 from cows and buffaloes, respectively, 17 S. simulans (18%); 6 and 11 isolates, respectively, and finally 12 S. hominis (12.9%); 5 and 7 isolates, respectively. Antimicrobial susceptibility testing showed that all isolates were sensitive to ceftriaxone, ciprofloxacin, ofloxacin and sulfamethoxazole-trimethoprim. On the contrary, all isolates were resistant to penicillin and streptomycin. Multidrug resistance (MDR) was detected in 21 (22.3%) Staphylococci isolates. Biofilm formation capacity was phenotypically assessed on YESCA CR agar medium and showed that all Staphylococci isolates were curli-producing. Application of PCR technique revealed that sed, seb genes were the most prevalent genes in all isolates, followed by fnbA gene which was detected in 80% of the isolates, and then mecA, blaZ, and icaA with percentages of 60%, 40%, and 40%, respectively.

Salmonellosis is one of the most important problems in poultry industry and a critical food safety hazard. In the present study the prevalence of avian Salmonellosis was studied in different farms of broiler chickens in Beni Suef Governorate, Egypt during the period from January to April 2020. A total of 140 samples were taken from slaughtered diseased or freshly dead broiler chickens aged from one to 35 days. Bacteriological examination revealed that 7.14% of the samples were Salmonella positive. Serotyping of Salmonella isolates showed that S. kentucky, S. blegdam and S. virchow were recognized at rates of 40%, 30% and 30%, respectively. Antimicrobial susceptibility test revealed that all salmonella isolates were multidrug resistant (MDR). All isolates were resistant to oxytetracycline (100%) while 90% were resistant to amoxicillin-clavulanic acid, cefotaxime, sulfamethoxazole- trimethoprim and norofloxacin. On the other hand, 80% of isolates were sensitive to fosfomycin and nitrofurantoin. Results of screening of some MDR isolates by multiplex PCR for detection of some virulence genes showed that all the tested isolates (100%) had invA, stn, spvC genes meanwhile pefA was not detected in any isolate.
