A total of 135 birds of one day age were randomly divided into nine groups. The groups of prevention model received respective strains from day 1-35 and treatment model received lactobacilli from day 15-35 (after challenging with C. jejuni). These groups were given lactobacilli (~10 CFUs) while challenged with C. jejuni on day 14 by oral gavage (10 CFUs/bird). There were three control groups including A, B and I. Negative control (A) did not receive any treatment, C. jejuni was given to group B and group I was given Enrofloxacin formulation. Cloacal swabs were collected from birds of each group before and after challenge while the ceca were collected from birds after slaughtering (on day 35) for enumeration of aerobic bacteria, coliform, C. jejuni, lactobacilli and Bifidobacterium on selective agar plates. Effect of lactobacilli on weight gain and New Castle Disease vaccine (NDV) titer were also evaluated. Probiotic strain Lactobacillus gallinarum PL 53 considerably decreased log10 values of aerobic plate count (3.19±0.66), coliform count (2.83±0.22) and C. jejuni (3.98±0.77) in poultry. The probiotics also enhanced Lactobacillus and Bifidobacterium spp counts (~2-3 log increase). Treatment group C had maximum weight gain (1994±188.32g) and geometric mean titer (274.4) on day 28. The results of in-vivo experiments concluded that probiotic administration may be effective for targeted mitigation of C. jejuni in broiler birds. ©2019 PVJ.

The anti-diabetic potential was investigated through the levels of glucose and body weight. Moreover, to assess the extract’s safety, acute toxicity test was performed. In comparison with control group, significant reductions were observed in LDL, cholesterol, as well as blood glucose levels in diabetic rats that received date seed extract. Extract supplemented diabetic rats also showed a better tolerance to glucose, as well as reduced amounts of creatinine, urea, and alkaline phosphatase in their serum samples.

That is why this study was conducted to check its effect on health and production in buffaloes. Selected buffaloes were divided into groups (n=10) on the basis of body condition scores (BCS) i.e. (Low) BCS 1-3, (Medium) BCS 4-6 and (High) BCS 7-9, while ten animals served as control. All the groups received rbST (Boostin-250) 35 mg on alternate days and oxytocin 1 ml (10 I.U), starting on day 70 postpartum till the end of lactation. Blood samples were collected from each animal and serum was separated. Milk samples were used for milk composition parameters. The data on reproductive performance parameters was obtained from the farm record. The results indicated that mean serum Alanine aminotransferase (ALT), Aspartate aminotransferase (AST) and total oxidant status (TOS) values were higher (P≤0.01) during summer, while total antioxidant status showed opposite trend. Mean serum AST and TOS values were significantly (P≤0.01) higher in medium and high BCS buffaloes. Percentage of pregnant buffaloes was high in the high BCS group during summer. Mean milk fat contents were higher (P≤0.01) in buffaloes of high BCS while mean milk protein and lactose contents were significantly (P≤0.01) higher in medium BCS buffaloes. Fat, protein, lactose and solid not-fat (SNF) contents were higher during spring than summer. Mean milk lactose and SNF contents were higher (P≤0.01) in high than low and medium milk production groups. In conclusion, milk production was increased during summer and with rbST and decreased with oxytocin during spring, rbST and oxytocin treatments showed adverse effects on general health of Nili-Ravi buffaloes. ©2019 PVJ.

Persistent survival inside macrophages is a major cause of chronic infections with Brucella. Leucine-rich repeat kinase 2 (LRRK2), a large multidomain protein kinase, is associated with Parkinson’s disease, chronic inflammation and intracellular infections. Hence, we monitored the activation of the LRRK2 kinase in Brucella-infected cells and evaluated the function of LRRK2 kinase in the intracellular survival of Brucella. Our results show that Brucella abortus 2308 activated the LRRK2 kinase and that the kinase activity was inhibited by a LRRK2-specific inhibitor in a dose-dependent manner. LRRK2 silencing significantly increased the Th1 immune response and reduced the replication of Brucella abortus 2308, both in vitro and in vivo. LRRK2 also enhanced the phosphorylation level of Akt, thereby inhibiting Akt-mediated humoral immune responses during Brucella infection. Collectively, these findings confirm that LRRK2 acts to reduce innate immune responses by activation of PI3K-Akt pathway, thereby contributing to the intracellular survival of Brucella abortus 2308 in murine macrophages and in a mouse infection model. Therefore, LRRK2 kinase play a key role in infections with Brucella abortus 2308, which will provide new insights into the pathogenic mechanisms used by Brucella. ©2019 PVJ.

This study was conducted to evaluate the pharmacokinetics of Cefquinome after intramuscular (IM) and intravenous (IV) administration in layer birds for its safety evaluation. Twelve healthy layer birds were randomly allocated in two equal groups. Each group was administered with 5mg/kg b.w. of Cefquinome by intramuscular and intravenous routes. Highly sensitive high performance liquid chromatography with ultraviolet detection (HPLC-UV) method was developed for quantification of Cefquinome in layer bird’s plasma with >80% recovery. The Limit of detection and quantification were 0.02 and 0.05μg/ml, respectively. The pharmacokinetic data showed that mean Area under the curve (AUC) after IM and IV administration were 7.838±0.165 and 11.729±0.346h×μg/ml, respectively. The maximum concentration (Cmax) following IM administration (4.525±0.129 μg/ml) was almost same the mean Cmax after IV administration (4.635±0.270μg/ml). Time to reach maximum concentration (Tmax) after IV and IM administration were 0.1h and 0.5h, respectively. Cefquinome sulphate had a relatively shorter half-life (1.19±0.14h) after IV dose administration. The shorter half-life depicts a rapid elimination. Total recovery after each administration was greater than 75%. The mean resident time after IM and IV administration was found to be 1.528±0.09h and 1.988±0.0311h, respectively. The bioavailability after IM administration was 66.84±2.05%. This study indicated that Cefquinome sulphate has favorable pharmacokinetics following both administrations in healthy layer birds which can help to form optimum dosage regimes thus ultimately leading to its use for eradication of various systemic and local infections. ©2019 PVJ.

In this study, in European sea bass (Dicentrarchus labrax) specimens reared in ponds with heated water from a power plant showing symptoms of a vibriosis-like disease we aimed to characterize the bacterial community as well as some serum metabolic and immune parameters. Bacteriological analysis revealed an important contamination with fecal coliforms, Pseudomonas aeruginosa, Vibrio alginolyticus, yeasts and molds whilst fish tissues from both healthy and diseased specimens were positive for total aerobic flora and several potential pathogenic bacteria such as V. alginolyticus, Aeromonas hydrophila, Pasteurella multocida, P. aeruginosa, Proteus vulgaris and P. mirabilis. Additionally, Grimontia hollisae was only present in diseased fish tissues. Serum metabolic parameters such as aspartate aminotransferase, bile acids, creatine kinase, uric acid, glucose, globulin and potassium were generally increased in diseased fish though only the levels of phosphorous reached a significant level compared to the healthy specimens. Regarding fish innate immunity, our results showed no statistical differences between healthy and diseased fish on peroxidase, protease or antiprotease activity while the bactericidal activity against V. anguillarum was significantly decreased in diseased fish. Lastly, the gene expression of il1b, c3, dic and mpx was down-regulated in the blood of diseased fish while ighm was up-regulated. ©2018 PVJ.
