Abstract
Introduction Lumpy skin disease (LSD) is a highly contagious vector-borne viral disease of cattle. LSD has emerged in Bangladesh in 2019, causing significant economic losses due to its high morbidity and mortality. This research was designed to isolate, identify, and assess the immunogenicity of LSD virus (LSDV) using nodular tissue samples obtained from affected cattle during the 2019-20 outbreak across nine districts of Bangladesh. Methods To determine the presence of LSDV in nodular tissues, we initially used iiPCR and PCR, followed by histopathological examination. 151 were positive via iiPCR and PCR among the 180 collected samples. The PCR positive 151 samples were then inoculated into 10-day-old embryonated chicken eggs via the CAM route to isolate LSDV, confirmed through PCR. Subsequently, partial sequencing and phylogenetic analysis of the P32 gene were performed to determine the origin of the circulating LSDV strain. The immunogenicity of selected LSDV strains was assessed through an ELISA test. Results The PCR results revealed a distinct positive band at 192 bp in both the nodular tissue samples and the LSDV isolated from chicken embryo inoculations. Microscopic analysis of the nodular lesions revealed thickening of the epidermis, ballooning degeneration of keratinocytes, and proliferation of follicular epithelia. Additionally, mononuclear infiltration was observed at the demarcation line between infected and healthy tissue, with necrosis of muscular tissues beneath the epidermis. The LSDV isolate from Bangladesh exhibited a close genetic relationship with LSDV strains isolated from neighboring and other regional countries including India, Myanmar, and Mongolia. This observation strongly suggests the possibility of a transboundary spread of the LSD outbreak in Bangladesh during 2019-2020. The results of the immunogenicity test showed that the serum antibody titer remained at a protective level for up to 18 months following secondary immunization with inactivated LSDV antigen. This finding suggests that the inactivated LSDV antigen could be a potential vaccine candidate to protect cattle in Bangladesh against LSDV. Conclusion In conclusion, our research successfully isolated, identified, and characterized LSDV in cattle nodular tissues from the 2019-20 outbreak in Bangladesh. Furthermore, it provided insights into the probable origin of the circulating strain and investigated a potential vaccine candidate to protect cattle in the region from LSDV.

Unveiling Oxidative Stress-Induced Genotoxicity and Its Alleviation through Selenium and Vitamin E Therapy in Naturally Infected Cattle with Lumpy Skin Disease. Vet Sci 2023; 10:643. [PMID: 37999466 PMCID: PMC10675407 DOI: 10.3390/vetsci10110643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 10/24/2023] [Accepted: 11/02/2023] [Indexed: 11/25/2023] Open
Abstract
Lumpy skin disease (LSD) is a contagious infection of cattle caused by a virus of the Poxviridae family, genus Capripoxvirus. In Pakistan, recent outbreaks have resulted in significant nationwide mortality and economic losses. A 20-day prospective cohort study was performed on sixty infected cattle with the aim to evaluate LSD-induced oxidative stress's genotoxic role and to determine the ameliorative effect of antioxidant therapy using principal component analysis (PCA) and a multivariable ordinal logistic regression model. LSDV was identified from scab samples and nodular lesions using RPO30-specific gene primers. The infected cattle were divided into control and treated groups. The animals were observed initially and finally on day 20 to evaluate the homeostatic, oxidative, and genotoxic changes. The animals in the treated group were administered a combination of selenium (Se) and vitamin E at the standard dose rate for five consecutive days. A substantial (p < 0.05) improvement in the hematological indices was observed in the treated group. The treated group also showed a significant (p < 0.05) reduction in levels of serum nitric oxide (NO) and malondialdehyde (MDA) post-therapy. The PCA at the final sampling data of the treated group showed that Principal Component (PC1 eigenvalue 1.429) was influenced by superoxide dismutase (SOD; 0.3632), catalase (CAT; 0.2906), and glutathione (GSH; 0.0816) and PC2 (eigenvalue 1.200) was influenced by CAT (0.4362), MDA (0.2056), and NO (0.0693). A significant correlation between serum NO (76%) and MDA levels (80%) was observed with genetic damage index (GDI) scores. The ordinal logistic regression model regarding the use of antioxidant therapy revealed 73.95-times (95%CI; 17.36-314.96) improvement in the GDI in treated animals. The multivariable ordinal logistic regression showed that each unit increase in NO and MDA resulted in a 13% increase in genotoxicity in infected individuals. In conclusion, our study revealed that LSD-induced oxidative stress and lipid peroxidation product causes genotoxicity in affected animals. Furthermore, the combined Se and vitamin E therapy significantly alleviated oxidative stress and genotoxicity in LSD-affected cattle.

Abstract
Lumpy skin disease (LSD) is a vector-borne viral transboundary disease of cattle caused by the LSD virus (LSDV). Despite investigations on clinical and outbreak features of LSDV, information on disease pathogenesis and alternative changes in blood parameters are scarce. Keeping this in view, the current study was designed to determine haematological, serum biochemical, and oxidative stress parameters in naturally infected cattle with LSDV during the recent surge of outbreaks in Punjab, Pakistan. A total of 35 blood samples was collected from polymerase chain reaction-confirmed LSDV-infected cattle for assessment of all parameters. The haematological examination of blood samples showed a significant reduction (p < 0.05) in different variables of erythrogram and leucogram. On the other hand, differences between levels of various serum biochemical parameters with the significant increase in levels of alkaline phosphatase, serum alanine aminotransferase, aspartate aminotransferase, and blood urea nitrogen were observed in LSDV naturally infected cattle. Moreover, malondialdehyde levels for lipid peroxidation and nitrate concentration were markedly elevated whereas glutathione S-transferase fluorescent and serum superoxide dismutase enzymes showed a decrease in levels. The current study suggests that alternations in haematological and serum biochemical parameters following LSDV infection stimulate oxidative stress and such findings may be useful for early and rapid diagnosis and improvement in the treatment strategy of the disease.

Abstract
Countries in the Indian subcontinent are currently facing a deadly epidemic of lumpy skin disease (LSD). LSD is primarily a disease of cattle. Buffaloes may sometimes develop mild illness, however, other domestic animals are considered resistant to LSD. We confirmed the LSDV infection in camels as evidenced by skin nodules on the body surface of the affected camels, isolation of LSD virus (LSDV) and amplification of LSDV-specific gene segments from the skin nodules (PCR), nucleotide sequencing of the viral genome and, demonstration of anti-LSDV antibodies in serum. Phylogenetic analysis based on nucleotide sequencing of ORF011, ORF012 and ORF036 revealed that the virus (LSDV/Camel/India/2022/Bikaner) is related to the historical NI-2490/Kenya/KSGP-like field strains which are predominantly circulating in the Indian subcontinent. This is the first report wherein LSDV has been to infect camels.

Abstract
Lumpy skin disease (LSD) is a notifiable re-emerging transboundary viral disease of bovines that inflicts heavy losses in affected livestock farms. Genetic variations contribute substantially to the inter-individual differences in the immune response against disease agents. The present study aimed to evaluate the genetic basis of differential immune response in Vrindavani cattle by comparing the hematological, biochemical and cytokine genes' expression profiles of LSD-affected and unaffected animals. After 21 days of the outbreak at the farm, the animals were grouped as affected (those who developed symptoms) and unaffected/healthy (those who did not). Standard hematological and biochemical parameters were evaluated in both the groups. Expression profiling of important Th1 (IL2, INFG and GMCSF) and Th2 (IL4, IL6 and IL10) cytokines was also performed via a relative quantification approach using real-time PCR. Erythrogram and leucogram analyses revealed significant differences in total leucocyte count (TLC: 14.18 ± 0.74 versus 11.38 ± 0.68 x103/µL), hemoglobin (Hb: 8.66 ± 0.42 versus 10.84 ± 0.17 g%) and percentage of neutrophils (46.40 ± 1.98 versus 35.40 ± 2.11%), lymphocytes (49.40 ± 1.99 versus 62.40 ± 1.86) and monocytes (4.20 ± 0.37 versus 2.40 ± 0.40) between the affected and healthy animals, respectively. The production of liver enzymes (SGOT and SGPT) was significantly higher in affected animals (74.18 ± 4.76 and 59.51 ± 2.75) when compared to the healthy counterparts (65.95 ± 9.18 and 39.21 ± 3.31). The expression profiling of Th1 and Th2 cytokines revealed significant differences between the two groups, except IL10. The expression of IL2, GMCSF and IL6 were upregulated in healthy animals while that of INFG, IL4 and IL10 were upregulated in LSD-affected animals. The highest abundance was observed for IL2 transcripts in healthy animals among all assessed cytokines with log2fold change of 1.61 as compared to affected counterparts. Overall, the immune response in healthy animals (after exposure to LSD virus) was predominated by the expression of Th1 cell proliferation and there was an increased production of pro-inflammatory cytokines as compared to the affected counterparts. The results revealed that the effective immune response to LSD in cattle consists of changes in hematological and biochemical parameters and altered expression profile of cytokines with enhanced phagocytosis and lymphocyte recruitment. Furthermore, optimal expression of Th1 cytokines is required for maintaining optimal health against infectious insult with LSD virus in cattle.

Abstract
Lumpy skin disease (LSD) is a highly infectious disease of cattle caused by a virus of the Poxviridae family, genus Capripoxvirus. The present study was designed to determine the prognostic ability of serum IL-6 in LSD using a binary logistic regression model at baseline sampling. A 17-day cohort study was conducted on a recent outbreak of LSD among cattle in the Lodhran District of Punjab, Pakistan. Infected cattle were divided into two categories based on their clinical status on day 17 as recovered (n = 33) or unrecovered (n = 17). Nodular lesions and scab specimens (n = 50) were used for the isolation of the lumpy skin disease virus and were confirmed by PCR. In recovered animals, hematological results showed marked leukocytosis, eosinophilia, lymphocytosis, neutrophilia, and monocytopenia. However, marked erythrocytosis, leukopenia, and thrombocytopenia were observed in the unrecovered animals at the final sampling point of the study. Serum levels of total protein, albumin, and glucose were significantly higher in the recovered animals. Meanwhile, aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenase, creatinine phosphokinase, total bilirubin, and direct bilirubin were found considerably higher in the unrecovered group. Receiver-operating characteristic curve analysis for serum IL-6 at baseline predicts the extended clinical conditions at the cut-off value of 85.16 pg/mL (55% specificity, 94% sensitivity, area under the curve 0.8039, respectively). In conclusion, the disease-induced hematological and biochemical alterations were significantly ameliorated in the recovered animals. In addition, the study revealed that serum IL-6 can be used as a valid marker for predicting the clinical worsening of LSD in cattle.

Abstract
Background and Aim: Lumpy skin disease (LSD) is a highly infectious endemic viral disease of cattle in Africa and the Middle East. The objectives of this study were to assess histopathological changes in cattle infected with LSD and measure serum malondialdehyde (MDA – oxidant) and total anti-oxidant capacity (TAC – anti-oxidant), trace elements (zinc, copper, and iron), cytokines (interleukin [IL]-1β, IL-6, and tumor necrosis factor-alpha [TNF-α]), haptoglobin (Hp), serum amyloid A (SAA), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine phosphokinase (CPK), blood urea nitrogen (BUN), and creatinine concentrations. Materials and Methods: Blood samples were collected from a total of sixty native and mixed breed cattle; (healthy; n = 25) and (LSD diseased; n = 35). Serum concentrations of MDA and TAC were measured by colorimetric methods. Serum IL-1β, IL-6, IL-10, TNF-α, Hp, and SAA concentrations were determined using human-specific enzyme-linked immunoassay kits. Results: Serum MDA, cytokine (IL-1β, IL-6, and TNF-α), Hp, SAA, AST, ALT, CPK, BUN, and creatinine concentrations were significantly higher, while TAC, IL-10, zinc, copper, and iron concentrations were significantly lower in LSD compared to healthy cattle (p < 0.05). Cows and exotic mixed breed cattle were at higher risk of LSD oxidative stress than bulls and local breeds (p < 0.05). Age was not associated with the risk of LSD (p > 0.05). Histologically, there was extensive tissue necrosis, severe vasculitis, mononuclear cell infiltration, and intracytoplasmic inclusion bodies. Conclusion: LSD is associated with pro-oxidative and pro-inflammatory states from imbalances that favor pro-oxidant and pro-inflammatory factors in the detriment of anti-oxidant and anti-inflammatory factors, leading to organ dysfunction and ultimately death. Oxidative stress is more frequent in cows and mixed breed cattle than in bulls and local breeds.

Abstract
Background Lumpy skin disease is a contagious viral disease of cattle caused by LSDV that results in huge economic losses in the cattle industry. This study characterizes LSDV in cattle through clinicopathological and molecular techniques in selected districts of Wolaita Zone, Southern Ethiopia. Methods A crossectional study was conducted from November 2020 to June 2021 using Real-time polymerase chain reaction and Histopathological techniques to confirm LSDV. Result This study revealed that the percentage of positivity of cattle for LSDV was 36.2%. Clinically, cattle infected with LSDV revealed fever (39–41 °C), nodular lesions on the skin and mucous membranes, and lymphadenopathy. Histopathologically, affected tissue revealed ballooning degenerations of the epidermis, infiltration of mononuclear inflammatory cells, vasculitis, and intracytoplasmic eosinophilic inclusion bodies. RT-PCR confirmed that DNA extracts from skin biopsies of virus isolates were positive for LSDV. Conclusion The present study confirms that LSDV is widely circulating in cattle of selected districts of the Wolaita zone. Thus, effective control measures through regular vaccination and further confirmation of circulating strains of LSDV through detailed molecular analysis should be recommended.

Abstract
Lumpy skin disease (LSD) is one of the major viral diseases still causing great economic losses among breeding flocks of Egypt. This study was designed to focus light on non-cutaneous lesions (prevalence, intensity, and impacts) among necropsied LSD infected cattle. We selected some dairy and beef flocks (Frisian breed) located in 3 governorates (Sharkia, Dakahlia, and Kaloubia) in Nile delta, Egypt, in the period from January 2019 to January 2020 for our survey study. The case history of farms declared no previous vaccination of examined farms. The clinical signs, morbidity, and mortality rates were recorded. Average morbidity and mortality percentage were 22.28% and 6.59%, respectively. PCR for specimens from liver, kidneys, heart, lungs, testis, udder, trachea, and lymph node indicates presence of amplicon capripoxvirus gene product at molecular weight size 192 bp. Postmortem lesions of necropsied and emergency slaughtered were recorded. The main detectable histopathology lesions among the infected animals were orchitis (75%), mastitis in immature and lactating udder (66.66%), and necrotic hepatitis (77.77%), disseminated vasculitis (61.11), glomerulonephritis (55.55), myocardial degeneration (50%), and serous atrophy of coronary fats (38.88%), lymphadenitis (88.88%), necrosis and depleted lymphoid tissue of spleen (38.88%), necrotic myositis (77.77%), tracheitis (16.66%), and pneumonia (interstitial bronchopneumonia) (44.44%) besides intra-cytoplasmic inclusions bodies in skin (33.33%). It could be concluded that higher mortalities of LSD may be due to systemic infection of infected animals which had great impact on economic losses among breeding flocks.

Prevalence of tick-borne haemoparasites and their perceived co-occurrences with viral outbreaks of FMD and LSD and their associated factors. Heliyon 2021; 7:e06479. [PMID: 33768176 PMCID: PMC7980057 DOI: 10.1016/j.heliyon.2021.e06479] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Revised: 11/02/2020] [Accepted: 03/05/2021] [Indexed: 11/21/2022] Open
Abstract
Species of Theileria, Babesia, and Anaplasma are Tick-borne pathogens (TBPs) that are prevalent throughout the world, particularly in the tropical and subtropical regions. Associated diseases of Theileriosis, Babesiosis, and Anaplasmosis, respectively, represents a major threat to livestock production in many countries. TBPs have a high prevalence in different geographical locations in Egypt. Foot and mouth disease (FMD) and Lumpy skin disease (LSD) are considered endemic bovine viral diseases in Egypt. Our clinical observations during the epidemics of LSD and FMD viruses showed higher prevalence rates for the TBPs. To investigate this correlation, a total of 670 samples from cattle and buffalo were collected during the summers of 2017 and 2018 distributed throughout ranches and smallholders in two geographical locations in Egypt. Two farms with a recent clinical outbreak of LSD with a total of 270 animals, while the other location included three farms with a recent FMD outbreak with a combined 400 cattle. Examined animals were classified mainly according to age, gender, species, breed (native versus crossbred), and the presence of ticks. Whole blood samples were collected for TBPs and viral (LSD and FMD) examinations, while tissue specimens were collected for detection of FMD and LSD viruses by real-time PCR. Our results confirmed significantly higher prevalence rates for the TBPs in LSD-positive than LSD-negative animals, while no significant difference could be detected for the prevalence rate of the TBPs in the FMD positive and negative groups. The prevalence of Babesia and Theileria was significantly (P < 0.05) higher in cross-breeds than native cattle. Infections with Anaplasma and co-infections with Babesia-Anaplasma and Theileria-Anaplasma were significantly higher in native than cross-breeds cattle. The intensity of parasitic infection (parasitemia) has a significant difference in the positive groups for the two viruses compared to the negative groups. These results collectively confirming the enhancing role of LSD on the prevalence rate of the haemoprotozoal infections leading to more serious outcomes to the livestock infections, and therefore the control of haemoprotozoal infections should be implemented as a part of viral epidemics control.

Abstract
Bovine uterine torsion refers to the rotation of the gravid uterus around its longitudinal axis. It is the dominant cause of dystocia in buffaloes. A total of two hundred and seventeen dystocia's Egyptian buffaloes were examined, and another twenty were apparently normal at the full term (healthy pregnant group). From the dystocia's buffaloes, twenty-three percentage (n = 50) was uterine torsion after gynecology inspection at presentation (Ut group) and 5 days after the manual correction (Utc group). The buffaloes with uterine torsion exhibited loss of appetite, constipation, colic, and straining. The incidence of torsion was mostly at first parity that accounting for 50% of cases. Regarding to the pregnancy stage, torsion mostly occurred at full term, where it primarily occurred in buffaloes at 3 years of age. Right-sided torsion ensued in 90% of all cases. The survival rate of the pregnant buffaloes was 90% (45 buffaloes), and 10% (5 buffaloes) was directed to the culling. Regarding to the fetal survival outcome, 30% of fetuses was survived where the other 70% was died. The hematological results denoted leucocytosis in Ut and Utc groups that attributed to neutrophilia, monocytosis, and eosinophilia. Biochemical assessments were denoted an augments in the levels of serum AST, LDH, CPK, creatinine, blood urea nitrogen, progesterone, cortisol, MDA, NO, TAC, blood lactate (bLac), TNF-α, and IL-6. Where there were a non significant fluctuations in the ALT, GGT, calcium, and phosphorus levels in the torsion cases. The significant declines in 17-β-oestradiol, total proteins, albumin, magnesium, and GSH levels in the dams suffering from Ut were observed. The robust elevations in AST (156 ± 3.47) and bLac (16.12 ± 0.18) with severe hypomagnesaemia (2.69 ± 0.15) were evident in 10% of the torsion cases that directed to the culling. This can conclude that robust elevations in AST and bLac with severe hypomagnesaemia are factors denoting a poor prognosis for uterine torsion in the buffaloes.

Abstract
Background and Aim Lumpy skin disease (LSD), an infectious disease of cattle, is characterized by raised nodules on the skin. Although the morbidity rate of LSD is low, it has a considerable fatality rate. Despite the annual mass vaccination of livestock with sheep pox vaccine (Veterinary Serum and Vaccine Research Institute, Egypt) enforced by Egyptian authorities, the LSD virus (LSDV) continues to circulate almost every summer. The present study aimed to discover the cause of cows naturally infected with LSDV circulating in Upper Egypt during the summer of 2018 using polymerase chain reaction (PCR) assay and to analyze their phylogenetics against reference genome sequences. Materials and Methods We cultured LSDV in specific pathogen-free embryonated chicken eggs (SPF-ECE) and used conventional PCR to identify fusion and P32 genes, previously deposited in GenBank (MN694826, MN694827, and MN954664). Sequencing and phylogenetic analyses were performed on these two highly conserved viral genes. Results LSDV infection of SPF-ECE resulted in characteristic white pock lesions. PCR products were identified on 1.5% agarose gel after electrophoresis at the expected positions for the fusion and P32 genes at 472 and 587 bp, respectively. Conclusion The present study revealed that the two viral genes were identified from the Beni Suef and Sohag Governorates in all clinical cases and confirmed the circulation of LSDV in this outbreak. After sequencing, these genes were identical to those of the LSDV that had been identified and recorded in GenBank for the past 3 years.

Abstract
The toxic effect of deltamethrin (DM) was documented in aquaculture. There is no obtainable data on the effect of Chlorella vulgaris against DM toxicity. The current study focused on the effect of dietary supplementation with C. vulgaris (CV) on growth performance, innate immune response, antioxidant activities, and transcriptomics disorders induced by sub-lethal dose of DM in Oreochromis niloticus. A total number of 216 O. niloticus divided into four groups with tri-replicates. The 1st control group (CT) fed a basal diet, the second group fed diet enriched with 5% CV. The third group was exposed to DM (15 μg/L), where the last group fed CV and simultaneously exposed to DM as previous-mentioned. The procedure of CV feeding and DM exposure were continued for two months. Exposures to DM revealed in stunting of the growth parameters and lessening of survival ratio of tilapias with a significant decline of the erythrogram (macrocytic hypochromic anemic picture), and leucocytes immune cells and related parameters (immunoglobulin M, lysozyme) and sever shifting in the antioxidant indicators. Sever raise was monitored in hepatic and kidney markers. Also, genes expression related to immune and antioxidant parameters were severely impacted. Where tilapias received CV showed a significant increase in the growth and immune parameters besides to an improvement of hematological, antioxidant values and their related genes expressions. The fourth group that received CV simultaneous with DM exposure showed a soothing of the previous indicators and markers toward the values of tilapias fed on basal diet (CT). In turn, CV supplementation may be presented a protective effect alongside DM toxicity in O. niloticus appeared through soothing of the immune, antioxidant and related genes expressions in addition to its hepato-renal protective effects. Therefore, the current study recommended that an incorporating of 5% CV for tilapias diet could improve their growth performance, immunity, antioxidant and transcriptomics disorders induced by deltamethrin.

Abstract
Lumpy skin disease (LSD) is a disease of cattle and domestic buffaloes caused by Capripoxvirus which can lead to significant economic losses. Until several years ago it was limited to Africa and the Middle East, but recently it was reported in Turkey (2013), Greece (2015), and in 2016 it spread to Bulgaria, North Macedonia, Albania, Montenegro and Serbia. The aim of this study was to determine the microscopic lesions in the skin of naturally infected animals, highlight their features and compare them to the findings of other authors. Gross lesions in the skin of cattle infected with Lumpy skin disease virus (LSDV) were manifested in the form of skin nodules which were round, raised, clearly circumscribed, firm and randomly distributed in the whole skin including the vulva and udder. Histopathological lesions included degeneration of epithelial cells, hyperkeratosis, spongiosis, and acanthosis present in 85.88%, 81.18%, 84.71%, and 80.0% of samples, respectively. Intracytoplasmic inclusion bodies were noted in keratinocytes of the stratum spinosum in 56.47% of samples, and in hair follicle cells and sebaceous glands epithelial cells in 45.88% of samples. Cutaneous lesions were in the form of inflammatory infiltrate present in the dermis and subcutis in 97.65% of samples. Since there are only a few literature data in this field, this study expands the knowledge relating to morphological alterations in LSD. Based on the characteristic microscopic lesions described in the present study, histopathology should be considered as a very useful method for the diagnosis of LSD.

Abstract
This study is aimed to appraise the impact of dietary supplementation with Echinacea purpurea (EP) in broiler chickens infected by pathogenic E. coli. Eighty-one-day-old chicks of both sexes, commercial Hubbard chicks, were divided into 4 groups. The first was kept as normal control, the second was supplemented by EP (5 mg/kg feed) from the first day to the end, where the third was infected orally by 1 ml E. coli O78 at 107 CFU intra-crop at 7 days old, while the last group was supplemented by EP and infected by the E. coli O78 as previously described . E. coli-infected chicks disclosed severe symptoms with mortality 30%. Where, the infected and EP supplemented group showed less clinical symptoms and 15% mortality. EP-supplemented groups showed a significant improvement in their body weight in comparing with infected group. E. coli-infected chickens revealed a significant drop in lymphocytes' number with a significant elevation in monocyte and heterophils with non-significant changes in total leucocyte count when matched with gp. (1), while the fourth group revealed non-significant changes in total leucocyte with a significant drop in heterophils and monocyte and a significant elevation in the lymphocytes matching with the 3rd group. Serum biochemical markers of liver, kidneys, and immunological parameters showed sever adverse alterations associated with E. coli infection. Dietary supplementations with Echinacea purpurea improve the final body weight and immune response of non-infected chicks and have a respectable effect for facing E. coli infection. EP improves hematological and serum biochemical adverse effects occured by E. coli infection. Histopathology of liver, kidneys, intestines, and spleen confirms these alterations.

Abstract
As recently applicable, there are few studies on the impact of using nano-selenium (nano-Se) on varied fish species. Where nothing reachable focused on its impact on tilapias so, the present analysis evaluated the efficacy of using nano-Se in tilapias on immune response, antioxidant defense compared by conventional Se form. 480 O. niloticus fingerlings were haphazardly grouped firstly into three groups with four replicates of each. The control one (CT) was fed on a basal diet. The second and third one supplemented with 0.7 mg/kg-1 Se and nano-Se respectively for ten weeks. At the start day of the ninth week, two replicates from each group were injected by Streptococcus iniae where, the remaining replicates stand without challenge. Enhancement of growth performance measurements were noted in nano-Se compared to Se or CT groups. Existed anemia in S. iniae tilapias became alleviated by using nano-Se that also, improves the alteration of leucogram induced by challenge. Elevation of aminotransferases, alkaline phosphatase, lactate dehydrogenase (ALT, AST, ALP and LDH) and creatinine in Se and CT challenged replicates that seemed nearly normal by using nano-Se. Usage of nano-Se showed more powerful antioxidant activities than Se. There were an expansion of immunoglobulin M, lysozymes, glutathione peroxidase, nitric oxide, superoxide dismutase and catalase (IgM, LYZ, GPx, NO, SOD, CAT) and their related gene expression in nano-Se with contrast in Se or CT challenged groups. Nile tilapias challenged by S. iniae disclosed substantial expansion in the percentage of mortality in CT challenged fish (93.33%), followed by the group supplemented with Se (73.33%), whereas the lowermost one at fish supplemented by nano-Se (26.66%). The mortalities have been stopped from the 5th, 12th and 14th days in, nano-Se, Se and CT respectively. It can be concluded that using of Se 0.7 mg/kg-1induce immunosuppressive, antioxidant, liver and kidneys negative impact on tilapias where the same dose from nano-Se was more potent immunomodulating and antioxidant. Also it is attend in counteracting the serious impact induced by S. iniae challenge.

Abstract
Our study is considered to attempt reducing the immune-toxic and antioxidant impacts of exposure to fipronil (FP) on Nile tilapia, Oreochromis niloticus using the β-glucan (βG). Two hundred and seventy fingerlings of Nile tilapia were divided randomly into six groups (45 tilapias of each, in 3 replicates): group I control (CT) group nourished on a basal diet. Group II (βG) nourished a basal diet supplemented with 0.4% βG. Groups III (1/20 FP) and V (1/10 FP) was exposed to 1/20 and 1/10 of the 96 h LC50 of FP in water and nourished the basal diet respectively. Groups IV (1/20 FP+ βG) and VI (1/10 FP+ βG) were exposed to 1/20 and 1/10 FP concomitantly with 0.4% βG supplementation for 90 successive days. Growth performance metrics were higher in βG group than CT. While those metrics were fallen at exposure to 1/20 or 1/10 FP. Supplementation with βG elevated the IgM and lysozyme levels.Whereas, tilapias exposed to FP only at different concentration showed lowering of those compared to CT. Supplementation with βG was effectively augmented IgM and lysozyme in 1/20 FP exposed tilapias. Furthermore, in a minor grade at 1/10 FP exposed tilapias. Exposure to FP increased the activities of hepatic markers chiefly at 1/10, however the βG supplementation was successfully improved these markers. There was imbalance of cortisol level at FP exposure where, βG combining to FP alleviate this disparity. There was fallen in LDH, MDH and FDPase in βG tilapias where continuing raise in 1/10 FP followed by 1/20 FP. βG supplementation raise the level of GSH, without significant variations in MDA conversely occurs in FP alone. Genes expression of βG caused raise of both GPx and GR, without fluctuations in CAT and SOD. Exposure to FP diminishes all evaluated antioxidant genes. It could fulfilled that supplementation with βG successfully alleviated the immune-toxic and antioxidant impact of FP in tilapias.

Abstract
BACKGROUND AND AIM Lumpy skin disease (LSD) is a highly infectious viral disease upsetting cattle, caused by LSD virus (LSDV) within the family Poxviridae. Sporadic cases of LSD have been observed in cattle previously vaccinated with the Romanian sheep poxvirus (SPPV) vaccine during the summer of 2016 in Sharkia province, Egypt. The present study was undertaken to perform molecular characterization of LSDV strains which circulated in this period as well as investigate their phylogenetic relatedness with published reference capripoxvirus genome sequences. MATERIALS AND METHODS A total of 82 skin nodules, as well as 5 lymph nodes, were collected from suspect LSD cases, and the virus was isolated in embryonated chicken eggs (ECEs). LSD was confirmed by polymerase chain reactions amplification of the partial and full-length sequences of the attachment and G-protein-coupled chemokine receptor (GPCR) genes, respectively, as well as a histopathological examination of the lesions. Molecular characterization of the LSDV isolates was conducted by sequencing the GPCR gene. RESULTS Characteristic skin nodules that covered the whole intact skin, as well as lymphadenopathy, were significant clinical signs in all suspected cases. LSDV isolation in ECEs revealed the characteristic focal white pock lesions dispersed on the chorioallantoic membranes. Histopathologic examination showed characteristic eosinophilic intracytoplasmic inclusion bodies within inflammatory cell infiltration. Phylogenetic analysis revealed that the LSDV isolates were clustered together with other African and European LSDV strains. In addition, the LSDV isolates have a unique signature of LSDVs (A11, T12, T34, S99, and P199). CONCLUSION LSDV infections have been detected in cattle previously vaccinated with Romanian SPPV vaccine during the summer of 2016 and making the evaluation of vaccine efficacy under field conditions necessary.

Abstract
The present study was performed to investigate the clinical impact and certain virological and haematological parameters following immunization of cattle against lumpy skin disease (LSD). The study was conducted in a dairy cattle farm (215 animals), immunized with a Neethling strain-based live vaccine. Twenty-seven animals (14 lactating cows, four dry cows and nine calves) were randomly selected for repetitive blood and saliva samplings. An EvaGreen-based real-time PCR was designed to differentiate vaccine from field LSDVs. Vaccinated animals underwent examination for adverse reactions. Nodule samples were collected from two representative cases for histopathological testing and virus identification. Milk yield was calculated based on bulk-tank measurements of all lactating cows (79). Viral DNA was detected between days 6-15 post-vaccination (p.v.) at 63% of the sampled animals (17/27). Saliva and bulk-tank milk samples were LSDV-negative. Pronounced swelling was observed at injection sites of 12% of the immunized animals (26/215), starting at day 6 p.v., and was resolved after 2-4 days. Small-sized (<0.5 cm) cutaneous lumps were developed between days 8-18 p.v. at 9% of the vaccinated animals (19/215). These were observed in adult cows and not in calves/heifers. Resolution was observable 10 days post-development. The vaccine virus was also identified in nodules and injection-site aspirates. Haematological changes (e.g., lower leucocyte counts) were observed in cows and not in calves. Daily milk production was being reduced during the first 12 days p.v. LSD immunization of cows resulted in nodules and low viraemia levels. The fact that nodules and haematological changes were not observed in calves, along with the low viraemia, supports the reduced virulence of the Neethling vaccine strain. The characteristic nodules in vaccinated animals could allow clinical differentiation from those observed in LSD. The developed real-time PCR efficiently differentiates infected from vaccinated cattle, and should be further validated as a tool in LSD surveillance.
