Ragab G. H. | Seif M. M. | Fatma M. Halfaya
This study aimed to evaluate intramuscularly administered ketamine, intravenously administered ketamine and intravenously administered propofol in diazepam premedicated goats. Nine native female goats divided into three groups (each of 3 goats) were premedicated with diazepam 1 mg/kg intramuscularly. Goats of group I were treated with ketamine (8 mg/kg) intravenously, while those of group II treated with ketamine (10 mg/kg) intramuscularly, and group III injected with propofol (5 mg/kg) intravenously. The mean anesthetic onset, anesthetic duration, and total recovery period were calculated. The mean heart rate (HR), respiratory rate (RR), rectal temperature (RT) and biochemical parameters also were recorded. Satisfactory anesthesia and immobilization (smooth induction, and smooth recovery) needed for surgical interventions of short duration were achieved in all groups. The induction was good and smooth in groups I and III. The quality of recovery was good in groups III and I and recovery is longer in group II. In conclusion, this study indicates that the 3 regimens are associated with acceptable anesthetic characteristics; Propofol IV is superior to ketamine because it provides uneventful onset and recovery which are more rapid than ketamine IV or ketamine IM, so reduces anaesthetic risk while administration of ketamine intravenously is superior to its administration intramuscularly

Newcastle Disease virus (NDV) and Avian Influenza virus (AI) are represent a great negative significant causing severe economic losses and increased mortalities worldwide. Newcastle disease (ND) and Avian Influenza (AI) vaccination were targeting to lower the losses from mortality, reduce the viral load in the environment as well as eradication of positive cases. Many immunostimulants had been used to improve the immune response of vaccinated chickens. The current study was designed to compare the effect of different immunostimulants on chick's immune response to bivalent ND with AI-H5N1 oil vaccine. One hundred and ten, 1- day old Baladi chicks, At the 1st day of life (0 day) 10 birds were sacrificed to obtained individual blood samples for serum to determine maternal antibodies (MDAbs) to both AI and ND. Rest of birds (100 chicks) were divided into 5 equal groups (1-5); each 20 chicks. All chicken groups were vaccinated against ND with eye drop instillation of HB1 vaccine. While, at the 9th day birds of the groups 1-3 and 5 were given H5N1 vaccine by S.C injection, birds of group 4 were lifted as non AI vaccinated control. The used immune stimulants under test were given to groups 1, 2, and 3 as follows Lector, Superimmune and Imuvral; respectively. All the groups were subjected to daily observation with recording of feed intake, weekly body weight gain and total FCR, Weekly serum samples were collected, for serological examination, and the results showed high antibody titers, low mortality rates and better body performance in the groups treated with immunostimulants than the other groups which were not treated with the immunostimulants

Duck Hepatitis virus (DHV) causes great economic losses in waterfowl industry worldwide. 3D gene, lies in the P3 segment of the picornavirus genome, is highly conserved and is a non-structural polyprotein gene, its encoding protein contains a conserved domain termed RNA-dependentRNA polymerase which participates in the synthesis of virus RNA during virus replication. The current work describes the surveillance of DHV in 20 commercial duck farms in Egypt with a history of high mortality in 3 to 15 day-old young ducklings from 2014 to 2016. Clinical samples were examined by Real Time-Polymerase Chain Reaction assays followed by partial sequence analysis of the 3D gene of the positive samples. Histopathological examination of the liver from selected samples was also conducted. The overall positive rate was 50% (n = 10/20). All duck breeds (Pekin, Muscovy and Mallard) used in the study were found to be susceptible to the disease. Histopathological findings of the liver samples showed pronounced lesions including hepatocyte degeneration and necrosis. Also, apoptosis were observed and bile duct hyperplasia, together with varying degrees of inflammatory cell response and haemorrhage. Sequence and phylogenetic analyses indicated that the Egyptian strains cluster in the DHAV serotype 1 with Asian viruses and distant from the vaccine strains used in Egypt.

The ability of L. monocytogenesas an opportunistic pathogen of humans and animals, to survive and grow under various adverse environmental conditions, makes it a potential health hazard afterthe consumption of contaminated dairy products, it often implicated in several outbreaks of listeriosis. This study was conducted to investigate the survival of L. monocytogenes strain (NCTC13372) when inoculated with a population level of 6.95 log cfu/g and 7.64 logcfu/g and stored at 4ºC for 15 days and 3 months at -18ºC for yoghurt and ice cream respectively. The obtained results indicated that complete inactivation of the tested organism wasn’t achieved till the end of storage periods and the inoculated L. monocytogenes was survived in both yoghurt and ice cream throughout the trial. It is concluded that in the dairy industry, we cannot rely upon either fermentation process and storage at refrigerating temperature or upon storage at freezing temperature during yoghurt and ice cream manufacturing to control L.monocytogenes pathogen in order to provide safe products for consumption.

Schistosoma mansoni worms inhabit the portal triad affecting blood elements. Therefore, the current study aimed to compare ameliorative effects of Commiphora molmol extract (Mirazid, MZD) and praziquantel (PZQ) on some biochemical parameters in S. mansoni-infected mice. Accordingly, Swiss albino mice (n=72) were used and were divided into 4 equal groups; 18 mice each. Group (1) was uninfected non-treated control. Mice in infected groups administered 100 S. mansoni cercariae/mouse. Group (2) contained infected non-treated mice. Group (3) was infected and treated with MZD at a dose of 500 mg/kg for 5 successive days. Group (4) was infected and treated with PZQ in a dose of 500 mg/kg for 2 successive days. Treatment started 7 weeks post infection (WPT) by the oral route. Blood samples were collected at the 1st, 2nd and 4th weeks post treatment for liver functions (ALT, AST and ALP), kidney functions tests (blood urea and serum creatinine) and cholinergic function (serum cholinesterase level). PZQ ameliorated activities of serum enzymes; alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase more than MZD compared to infected untreated group. PZQ significantly decreased ALT at 1, 2 and 4 WPT as well as AST and ALP activity at 2 and 4 WPT whereas, MZD resulted in significant reduction in ALT activity at the 1st, 2nd and 4th WPT. AST and ALP activities appeared at the 2nd and 4th WPT. PZQ caused progressive significant reduction in elevated levels of urea and creatinine at the 1st, 2nd and 4th WPT, respectively that produced by MZD. PZQ and MZD induced a significant elevation in the level of AChE. Such effect was early detected MZD, and it was showed at the 2nd and 4th WPT for PZQ. It was concluded that PZQ and MZD were safe drugs with no adverse biochemical effects on S. mansoni-infected treated mice with potential action done by PZQ rather than MZD.

Ragab G. H. | Seif M. M | Fatma M. Halfaya
The aim of this study was to compare the analgesic effect of tramadol, lidocaine and tramadol-lidocaine combination injected in the epidural space in goats. Nine goats were used to compare the epidural analgesic effect of tramadol (3 mg / kg), 2% lidocaine (2.86 mg/kg) and tramadol-lidocaine combination (1 mg /kg and 2.46 mg kg, resp.). Onset time, duration, and degree of analgesia and ataxia were recorded as well as Heart rate (HR), respiratory rate (RR), rectal temperature (RT), and biochemical parameters were recorded. Time to onset and duration of analgesia, were tramadol 10 min and 225 min; lidocaine 4 min and 85 min and tramadol-lidocaine 4 min and 130 min respectively. Onset time and duration were significantly longer with tramadol and tramadol-lidocaine combination than the other treatment. Ataxia was not observed in tramadol and mildly observed in tramadol-lidocaine combination and was severing in lidocaine. Tramadol and tramadol-lidocaine combination might be clinically useful to provide analgesia in goats for long-duration surgical procedures than lidocaine alone.

There is paucity of information on the prevalence of leptospirosis in wildlife in Nigeria. This study investigated the prevalence and renal pathology of leptospirosis in wild animals in Southwest Nigeria. One hundred and five kidney samples were examined from 10 different wildlife species (antelope) greater cane rat (GCR), hare, African giant rat (AGR), tree hyrax, civet cat, monitor lizard, python, bushbuck and partridge) using a combination of Ellinghausen McCullough Johnson Harris (EMJH) medium, microscopic agglutination test (MAT), Warthin– Starry silver stain (WSss) and immunohistochemistry. Chi-square test was used with confidence level set at 0.05 to ascertain associations between positive cases and sex and species. Eightytwo (78.1%) samples were culturally positive, while 67.7% (63/93), 57.0% (16/28) and 66.7% (8/12) were WSss, MAT and immunohistochemically positive, respectively. Interstitial nephritis (41.0%) and tubular nephrosis (81.0%) were the most prominent histopathological changes. Pathogenic Leptospira organisms were highest in GCR (32.1%) and antelope (14.3%). Serovars hardjo (11.54%), bratislava (3.9%), canicola (3.9%), icterohaemorrhagiae (15.4%), pomona (7.14%) gripptotyphosa (19.2%) and undetermined isolates were also detected in other animals. The result showed high prevalence of Leptospira infection in the wild and the possibility of domestic animals and humans contracting the disease. This study is the first documentation of evidence of pathogenic Leptospira species in wildlife in Nigeria.

Query (Q) fever is a globally distributed zoonotic disease caused by Coxiella burnetii, a bacterial agent for which ruminants are the most prevalent natural reservoir. Data regarding Q fever infection in camels in Algeria are limited. Therefore, a survey to detect seroprevalence of C. burnetii antibodies was conducted among healthy camel populations in a vast area in southeastern Algeria to determine distribution of the Q fever causative organism and to identify risk factors associated with infection. Between January and March 2016, blood samples were collected from 184 camels and serum samples were subsequently analysed using a commercial Enzyme-Linked Immunosorbent Assay (ELISA) kit. At the time of blood collection, a questionnaire investigating 13 potential predisposing factors associated with C. burnetii seropositivity was completed for every dromedary camel and herd. Results were analysed by a chi-square (χ2) test and multivariate logistic regression. The seroprevalence of C. burnetii at the animal level was 71.2% (95% CI: 65.2–78.3) and 85.3% (95% CI: 72.8–97.8) at the herd level. At the animal level, differences in seroprevalence were observed because of herd size, animal age, animal sex, presence of ticks and contact with other herds. A multivariable logistic regression model identified three main risk factors associated with individual seropositivity: (1) age class > 11 years (OR = 8.81, 95% CI: 2.55–30.41), (2) herd size > 50 head (OR = 4.46, 95% CI: 1.01–19.59) and (3) infestation with ticks (OR 2.2; 95% CI: 1.1–4.5). This study of seroprevalence of C. burnetii infection in camels in Algeria revealed a high seroprevalence of Q fever in camel populations in southeastern Algeria and provided strong evidence that Q fever represents an economic, public health and veterinary concern. Appropriate measures should be taken to prevent the spread of C. burnetii and to reduce the risk of Q fever in farm animals and humans in this agro-ecologically and strategically important region of North Africa.

Stability study of biological products especially living bacterial vaccines plays an important role for the determination of product changes in maintenance period, and ensures safety, efficacy and maintenance of biological properties of the vaccines. So, the objective of this study was to establish stability and keeping quality of the local Brucella melitensis Rev-1 vaccine using different types of stabilizers in lyophilization process. A long-term stability study was carried out for four batches of reduced-dose Brucella melitensis Rev-1 vaccine manufactured by veterinary serum and vaccine research institute using four different stabilizers. Stabilizers were: (A) sucrose and skimmed milk, (B and C) different concentrations of sucrose, sodium glutamate and gelatin, and (D) casein, sucrose and sodium glutamate. The quality control tests including colony forming unit, purity, dissociation and physicochemical tests on all batches until 12 months postproduction were performed. The obtained results indicated that in spite of collapse (shrinkage) of lyophilized cake in a number of bottles in batches prepared using stabilizer A, Brucella vaccine batches were stable and met the specification recommended by OIE 2012 for 12 months post-production in vaccine batches with stabilizers A and D.
