Potential use of a recombinant replication-defective adenovirus vector carrying the C-terminal portion of the P97 adhesin protein as a vaccine against Mycoplasma hyopneumoniae in swine.

Mycoplasma hyopneumoniae causes severe economic losses to the swine industry worldwide and the prevention of its related disease, enzootic porcine pneumonia, remains a challenge. The P97 adhesin protein of M. hyopneumoniae should be a good candidate for the development of a subunit vaccine because antibodies produced against P97 could prevent the adhesion of the pathogen to the respiratory epithelial cells in vitro. In the present study, a P97 recombinant replication-defective adenovirus (rAdP97c) subunit vaccine efficiency was evaluated in pigs. The rAdP97c vaccine was found to induce both strong P97 specific humoral and cellular immune responses. The rAdP97c vaccinated pigs developed a lower amount of macroscopic lung lesions (18.5 ± 9.6%) compared to the unvaccinated and challenged animals (45.8 ± 11.5%). rAdP97c vaccine reduced significantly the severity of inflammatory response and the amount of M. hyopneumoniae in the respiratory tract. Furthermore, the average daily weight gain was slightly improved in the rAdP97c vaccinated pigs (0.672 ± 0.068 kg/day) compared to the unvaccinated and challenged animals (0.568 ± 0.104 kg/day). A bacterin-based commercial vaccine (Suvaxyn® MH-one) was more efficient to induce a protective immune response than rAdP97c even if it did not evoke a P97 specific immune response. These results suggest that immunodominant antigens other than P97 adhesin are also important in the induction of a protective immune response and should be taken into account in the future development of M. hyopneumoniae subunit vaccines.

The Application of a Pluralist Approach of Global Administrative Law on the Governance of Doping in Sport

Plusieurs problèmes liés à l'utilisation de substances et méthodes interdites de dopage dans les sports posent de grands défis à la gouvernance antidopage. Afin de lutter contre le dopage, certains pays ont mis en oeuvre des cadres juridiques basés exclusivement sur le droit pénal tandis que d'autres pays ont plutôt misé sur des mécanismes et organismes spécialisés trouvant fondement en droit privé ou sur un régime hybride de droit public et privé. Ces différentes approches réglementaires ont pour conséquence de faire en sorte qu’il est très difficile de lutter efficacement contre le dopage dans les sports, notamment parce que leur exécution requiert un degré de collaboration internationale et une participation concertée des autorités publiques qui est difficile à mettre en place. À l’heure actuelle, on peut par exemple observer que les États n’arrivent pas à contrer efficacement la participation des syndicats et organisations transnationales liés au crime organisé dans le marché du dopage, ni à éliminer des substances et méthodes de dopage interdites par la réglementation. Par ailleurs, la gouvernance antidopage basée sur les règles prescrites par l’Agence mondiale antidopage prévoit des règles et des normes distinctes de dopage distinguant entre deux catégories de personnes, les athlètes et les autres, plaçant ainsi les premiers dans une position désavantageuse. Par exemple, le standard de responsabilité stricte sans faute ou négligence imposé aux athlètes exige moins que la preuve hors de tout doute raisonnable et permet l'utilisation de preuves circonstancielles pour établir la violation des règles antidopages. S'appliquant pour prouver le dopage, ce standard mine le principe de la présomption d'innocence et le principe suivant lequel une personne ne devrait pas se voir imposer une peine sans loi. D’ailleurs, le nouveau Code de 2015 de l’Agence attribuera aux organisations nationales antidopage (ONADs) des pouvoirs d'enquête et de collecte de renseignements et ajoutera de nouvelles catégories de dopage non-analytiques, réduisant encore plus les droits des athlètes. Dans cette thèse, nous discutons plus particulièrement du régime réglementaire de l’Agence et fondé sur le droit privé parce qu’il ne parvient pas à répondre aux besoins actuels de gouvernance mondiale antidopage. Nous préconisons donc l’adoption d’une nouvelle approche de gouvernance antidopage où la nature publique et pénale mondiale du dopage est clairement reconnue. Cette reconnaissance combiné avec un modèle de gouvernance adapté basé sur une approche pluraliste du droit administratif global produira une réglementation et une administration antidopage mieux acceptée chez les athlètes et plus efficace sur le plan des résultats. Le nouveau modèle de gouvernance que nous proposons nécessitera toutefois que tous les acteurs étatiques et non-étatiques ajustent leur cadre de gouvernance en tenant compte de cette nouvelle approche, et ce, afin de confronter les défis actuels et de régler de manière plus satisfaisante les problèmes liés à la gouvernance mondiale du dopage dans les sports.

The Mobilization against the 2005 treaty establishing a constitution for Europe : a French mobilization for another Europe

Why did a majority of French voters reject the Treaty Establishing a Constitution for Europe in the 2005 referendum? We argue here that the collective mobilization of the left-wing ‘No’ camp made the decisive difference through its formation of ‘Collectifs pour le non’, a coalition which facilitated the public expression of an anti-liberal and pro-European position capable of bringing together the Green and Socialist electorates, along with other parts of the left. Using a comprehensive analysis of the multi-organizational field of protest constituted by the mobilization of the left-wing ‘No’ camp, we show first that the mobilization was a ‘European affair’, in the sense that it developed a pro-European position in the context of struggles against liberal forces. Second, we show that the mobilization was also a ‘French’ affair because it relied on the high valuation of the ‘national’ mode of belonging, through the defence of the French state model.

FosteraTM PRRS modified live vaccine efficacy against a Canadian heterologous virulent field strain of porcine reproductive and respiratory syndrome virus (PRRSV).

Vaccination is a useful option to control infection with porcine reproductive and respiratory syndrome virus (PRRSV), and several modified live-PRRSV vaccines have been developed. These vaccines have shown some efficacy in reducing the incidence and severity of clinical disease as well as the duration of viremia and virus shedding but have failed to provide sterilizing immunity. The efficacy of modified live-virus (MLV) vaccines is greater against a homologous strain compared with heterologous PRRSV strains. The objective of this study was to evaluate the efficacy of Fostera PRRS MLV vaccine in protecting against challenge with a heterologous field strain widely circulating in the swine herds of eastern Canada. Forty-six piglets were divided into 4 groups: nonvaccinated-nonchallenged; nonvaccinated-challenged; vaccinated-challenged; and vaccinated-nonchallenged. The animals were vaccinated at 23 d of age with Fostera PRRS and challenged 23 d later with a heterologous field strain of PRRSV (FMV12-1425619). Overall, the vaccine showed some beneficial effects in the challenged animals by reducing the severity of clinical signs and the viral load. A significant difference between nonvaccinated and vaccinated animals was detected for some parameters starting 11 to 13 d after challenge, which suggested that the cell-mediated immune response or other delayed responses could be more important than pre-existing PRRSV antibodies in vaccinated animals within the context of protection against heterologous strains.

Epistemic deontologism and the voluntarist strategy against doxastic involuntarism

According to the deontological conception of epistemic justification, a belief is justified when it is our obligation or duty as rational creatures to believe it. However, this view faces an important objection according to which we cannot have such epistemic obligations since our beliefs are never under our voluntary control. One possible strategy against this argument is to show that we do have voluntary control over some of our beliefs, and that we therefore have epistemic obligations. This is what I call the voluntarist strategy. I examine it and argue that it is not promising. I show how the voluntarist attempts of Carl Ginet and Brian Weatherson fail, and conclude that it would be more fruitful for deontologists to look for a different strategy.

The Financial Statement Insurance Alternative to Auditor Liability

These articles evaluate using financial statement insurance (FSI) to reduce the frequency and magnitude of audit failure. The FSI concept was pioneered by Josh Ronen, NYU Accounting Professor, who has modeled its economic aspects. My paper examines FSI’s efficacy from policy and legal perspectives. I conclude that while the model is not perfect, it promises considerable advantages over the current model. While some of the existing system’s imperfections are sustained or reappear in different guises, none of the existing imperfections appears to be aggravated and the rest likely are mitigated significantly. So I prescribe a framework to permit companies, on an experimental-basis and with investor approval, to use FSI as an optional alternative to financial statement auditing backed by auditor liability.

Investigation of Offences against National Security

The study is a close scrutiny of the process of investigation of offences in India along with an analysis of powers and functions of the investigating agency. The offences, which are prejudicial to sovereignty, integrity and security of the nation or to its friendly relations with foreign states, are generally called the offences against national security. Offences against national security being prejudicial to the very existence of the nation and its legal system, is a heinous and terrible one. As early as 1971 the Law Commission of India had pointed out the need of treating the offences relating to national security and their perpetrators on a totally different procedural footing. The recommendation that, all the offences coming under the said category ought to be brought under the purview of a single enactment so as to confront such offences effectively. The discrepancies in and inadequacies of the criminal justice system in India as much as they are related to the investigations of the offences against national security are examined and the reforms are also suggested. The quality of criminal justice is closely linked with the caliber of the prosecution system and many of the acquittals in courts can be ascribed not only to poor investigations but also to poor quality of prosecution.

Antiviral property of marine actinomycetes against White Spot Syndrome Virus in penaeid shrimps

Aquaculture farms, particularly in Southeast Asia are facing severe crisis due to increasing incidences of White Spot Syndrome Virus (WSSV). Actinomycetes have provided many important bioactive compounds of high prophylactic and therapeutic value and are continually being screened for new compounds. In this communication, the results of a study made to determine the effectiveness of marine actinomycetes against the white spot disease in penaeid shrimps are presented. Twenty-five isolates of actinomycetes were tested for their ability to reduce infection due to WSSV among cultured shrimps. When these actinomycetes were made available as feed additives to the post-larvae of the black tiger shrimp Penaeus monodon for two weeks and challenged with WSSV, the post challenge survival showed variations from 11 to 83%. However, six isolates have shown to be the most potential candidates for further study.

Diversity and antimicrobial activity of Lactic Acid Bacteria from the gut of marine fish Rastrelliger kanagurta against fish, shrimp and human pathogens

Emergence of antibiotic resistance among aquaculture pathogens has made it necessary to look into environment friendly, effective and sustainable methods such as probiotic and immunostimulants among others.. In the present study, LAB were isolated from the gut of fish species namely Rastrelliger kanagurta and analyzed for their antibacterial activity against various fish, shrimp and human pathogens. Different LAB species such as Lactobacillus plantarum, L. bulgaricus, L. brevis and L. viridiscens were encountered in the gut of R. kanagurta. Several strains showed good activity against fish, shrimp and human pathogens. LAB from the gut of such marine species may be developed as possible probiont for environment friendly health management of fresh water, estuarine and marine species currently exploited in aquaculture

Gut Associated Lactic Acid Bacteria Isolated from the Estuarine Fish Mugil cephalus: Molecular Diversity and Antibacterial Activities against Pathogens

In the present study we address the issue on gut associated lactic acid bacteria (LAB) isolated from the intestine of estuarine fish Mugil cephalus using de Man Rogossa and Sharpe (MRS) agar. LAB isolates were identified biochemically and screened for their ability to inhibit in vitro growth of various fish, shrimp and human pathogens. Most of the LAB isolates displayed an improved antagonism against fish pathogens compared to shrimp and human pathogens. Selected representative strains displaying high antibacterial activity were identified using 16S rRNA gene sequence analysis. Of the selected strains Lactobacillus brevis was the most predominant. Four other species of Lactobacillus, Enterobacter hormaechei and Enterobacter ludwigii were also identified. It was also observed that even among same species, considerable diversity with respect to substrate utilization persisted. Considering the euryhaline nature of grey mullet (Mugil cephalus), the LAB isolated from the gut possessed good tolerance to varying salt concentrations. This finding merits further investigation to evaluate whether the isolated LAB could be used as probiotics in various fresh and sea water aquaculture

“Rights of Women against Domestic Violence - The Law and Emerging Challenges”

Domestic violence is a gender based violation of human rights having multi- dimensional repercussions in the well- being of individuals in family and society. The Indian legislation to protect the women from domestic violence is significant in providing a mechanism for enforcing positive civil rights of protection and injunction orders to the victims of domestic violence along with the existing remedies of criminal sanctions. However the Act was brought in the backdrop of an established tradition of cohesive and stable family setting. This, in turn, results in the emergence of new issues and challenges which necessitates deeper understandings of indigenous sociocultural institutions in India i.e., marriage and family. This study is an attempt to analyse the Indian law on domestic violence and to assess whether the law addresses and answers the problems of domestic violence effectively in the culture specific setting of India

A brackishwater isolate of Pseudomonas PS-102, a potential antagonistic bacterium against pathogenic vibrios in penaeid and non-penaeid rearing systems

A Pseudomonas sp PS-102 recovered from Muttukkadu brackish water lagoon, situated south of Chennai, showed significant activity against a number of shrimp pathogenic vibrios. Out of the 112 isolates of bacterial pathogens comprising Vibrio harveyi, V. vulnificus, V. parahaemolyticus, V. alginolyticus, V. fluvialis, and Aeromonas spp, 73% were inhibited in vitro by the cell-free culture supernatant of Pseudomonas sp PS-102 isolate. The organism produced yellowish fluorescent pigment on King's B medium, hydrolysed starch and protein, and produced 36.4% siderophore units by CAS assay and 32 μM of catechol siderophores as estimated by Arnow's assay. The PS-102 isolate showed wide ranging environmental tolerance with, temperatures from 25 to 40 °C, pH from 6 to 8, salinity from 0 to 36 ppt, while the antagonistic activity peaked in cultures grown at 30 °C, pH 8.0 and at 5 ppt saline conditions. The antagonistic activity of the culture supernatant was evident even at 30% v / v dilution against V. harveyi. The preliminary studies on the nature of the antibacterial action indicated that the antagonistic principle as heat stable and resistant to proteolytic, lipolytic and amylolytic enzymes. Pseudomonas sp PS 102 was found to be safe to shrimp when PL-9 stage were challenged at 107 CFU ml−1 and by intramuscular injection into of ∼5 g sub-adults shrimp at 105 to 108 CFU. Further, its safety in a mammalian system, tested by its pathogenicity to mice, was also determined and its LD50 to BALB/c mice was found to be 109 CFU. The results of this study indicated that the organism Pseudomonas sp PS 102 could be employed as a potential probiont in shrimp and prawn aquaculture systems for management and control of bacterial infections

Probiotic Effects of Lactic Acid Bacteria Against Vibrio Alginolyticus in Penaeus (Fenneropenaeus) Indicus (H. Milne Edwards)

Cell free extracts of four strains of Lactic acid bacteria (LAB) viz. Lactobacillus. acidophilus, Streptococcus.cremoris, Lactobacillus bulgaricus –56 and Lactobacillus bulgaricus –57 inhibited growth of Vibrio alginolyticus in nutrient broth. The antagonism of LAB to Vibrio alginolyticus was further confirmed by streak plating wherein suppression of growth of Vibrio was obtained. Juveniles of Penaeus indicus (average weight 0.985 ± 0.1 g) on administering orally a moist feed base containing 5 × 106 cells·g of the four LAB probionts for a period of four weeks showed better survival (56 to 72%) when challenged with V. alginolyticus by intra-muscular injection of 0.1 ml containing 3 × 109 cells·ml. Animals maintained on a diet devoid of bacterial biomass exhibited 80% mortality. No external or internal pathological changes were observed in shrimp fed with the LAB incorporated diets. Results showed inhibition of V. alginolyticus by LAB and stimulation of the non-specific immune response resulting in resistance to disease in the shrimp fed on LAB incorporated diets.

Antimicrobial activity of chitosan against vibrios from freshwater prawn Macrobrachium rosenbergii larval rearing systems

Chitosan is a biocompatible and biodegradable natural polymer with established antimicrobial properties against specific microorganisms. The present study demonstrates its antibacterial activity against 48 isolates of Vibrio species from prawn larval rearing systems. The antibacterial activity had a positive correlation with the concentration of chitosan. This work opens up avenues for using chitosan as a prophylactic biopolymer for protecting prawn larvae from vibriosis.
