Genitors of the Pacific oyster Crassostrea gigas were submitted during gametogenesis to a short pulse exposure to the herbicide diuron at a realistic environmental concentration. Histological analysis showed no effect of diuron on gametogenesis course, sex ratio and reproductive effort. A non-significant increase in testosterone and progesterone levels was observed in genitors exposed to the herbicide. At cell level, diuron exposure was shown to modulate the phagocytic activity of circulating hemocytes. The results of a transcriptional analysis showed that diuron affected the expression of genes belonging to functions known to play a major role during oyster gametogenesis such as gene transcription regulation, DNA replication and repair, DNA methylation...

ABSTRACT: The objective of the present study was to evaluate the digestibility and the immunomodulatory effects of diets supplemented with lutein in dogs. Sixteen adult dogs were distributed in two groups (control and test) in a completely randomized design. Dogs were fed for 120 days with iso-nutritive diets, which only difference was the inclusion of 45g lutein/kg in the diet fed to the test group. Blood samples were collected in the beginning and at the end of the experimental period to evaluate total lymphocyte, lymphocyte proliferation index, and CD4+ and CD8+ lymphocyte counts. In order to evaluate apparent diet digestibility, dogs were housed in metabolic cages for ten days (five days of adaptation and five for faeces total collection). Coefficients...

Oysters are sessile filter feeders that live in close association with abundant and diverse communities of microorganisms that form the oyster microbiota. In such an association, cellular and molecular mechanisms have evolved to maintain oyster homeostasis upon stressful conditions including infection and changing environments. We give here cellular and molecular insights into the Crassostrea gigas antimicrobial defense system with focus on antimicrobial peptides and proteins (AMPs). This review highlights the central role of the hemocytes in the modulation and control of oyster antimicrobial response. As vehicles for AMPs and other antimicrobial effectors, including reactive oxygen species (ROS), and together with epithelia, hemocytes provide the oyster...

Brandão,Luciana Gomes Pedro; Brasil,Pedro Emmanuel Alvarenga Americano do; Oliveira,Silas de Souza; Silva,Edson Elias da; Lopes,Guilherme Santoro.

ABSTRACT In the current effort to eliminate polio from the world, it is important to recognize and vaccinate susceptible groups, especially immunocompromised patients living in countries where attenuated polio vaccine is still used. In this report, we describe the frequency of protective antibodies in a small sample of adult SOT candidates in whom previous vaccination could be ascertained. Patients included in this report were selected among the participants of an ongoing prospective study carried out at the Reference Center for Special Immunobiologicals of the Evandro Chagas National Institute of Infectious Diseases in Rio de Janeiro, Brazil. Among the first 100 patients enrolled in this study, only seven adult SOT candidates had proven polio vaccination...

Infectious Bursal Disease: Pathogenicity and Immunogenicity of Vaccines

Camilotti,E; Moraes,LB; Furian,TQ; Borges,KA; Moraes,HLS; Salle,CTP.

ABSTRACT The Infectious Bursal Disease (IBD) is a contagious viral disease that affects young chickens and may cause high morbidity and mortality. As the virus is very resistant to the environment, vaccination is required in case of high infection pressure. Due to variations in the virulence degree of the vaccines available to control IBD, this study aimed at evaluating the pathogenicity and immunogenicity of three types of vaccines. In total, 220 one-day-old specific pathogen free (SPF) chickens were immunized with recombinant, immune-complex and intermediate vaccines, or not vaccinated (55 birds per group) and challenged with IBD G11 strain on day 25. On days 25, 30, and 35, the Bursa of Fabricius (BF) were submitted to gross and histological...

Influence de l'environnement trophique de l'élevage en biofloc sur les performances physiologiques de la crevette Litopenaeus stylirostris : Étude de paramètres de la nutrition, de l'immunité et de la reproduction

Seroconversion and seroreactivity patterns of dairy goats naturally exposed to caprine arthritis-encephalitis virus in Brazil

Cardona, Emilie.

Biofloc is an intensive rearing system with zero or minimal water exchange where a diverse population of microorganisms (microalgae, zooplankton and bacteria) develops in association with organic matter to form the floc particles. These particles play the double role of biological filter and dietary supplement. This dissertation aims to better understand the process of this rearing system and its interactions with the Litopenaeus stylirostris shrimp. Two specific objectives were integrated within the framework of this general objective: (i) to measure the production gain from biofloc rearing and (ii) to study the interaction between biofloc environment and shrimp and to assess its role on production performances of shrimps. Thus, our results show...

A labelled avidin-biotin ELISA (lab-ELISA) using repeated serum samples of goats showed a progressive seroconversion with higher seroconversion rate at the period going from the beginning of the breeding up to the last half of lactation (35.0%), compared to that recorded at the beginning of breeding (17.8%)(p<0.05). Furthermore, the seroreactivity pattern, evaluated by a lab-ELISA standard-curve with serum samples collected at 30-40 days intervals during 12 months, was caracterized by high individual variability. No seroreversion was observed and there were higher titers in the group of animals which delivered kids and established a lactation period (n=6; mean titre=913.4 units) compared to the group of goats that failed to conceived (n=4; mean...

Advances in gastropod immunity from the study of the interaction between the snail Biomphalaria glabrata and its parasites: A review of research progress over the last decade

Heat stress and vitamin E in diets for broilers as a mitigating measure

Coustau, C.; Gourbal, B.; Duval, D.; Yoshino, T. P.; Adema, C. M.; Mitta, Guillaume.

This review summarizes the research progress made over the past decade in the field of gastropod immunity resulting from investigations of the interaction between the snail Biomphalaria glabrata and its trematode parasites. A combination of integrated approaches, including cellular, genetic and comparative molecular and proteomic approaches have revealed novel molecular components involved in mediating Biomphalaria immune responses that provide insights into the nature of host-parasite compatibility and the mechanisms involved in parasite recognition and killing. The current overview emphasizes that the interaction between B. glabrata and its trematode parasites involves a complex molecular crosstalk between numerous antigens, immune receptors, effectors...

This review aimed to identify the importance of vitamin E dietary supplementation to broilers subjected to heat stress in relation to metabolism, growth performance and quality of animal products and its effects on immune system. Vitamin E is the concentration of tocopherol and tocotrienol, which can be found in natural or synthetic form. This vitamin is essential for the integrity of reproductive, muscular, circulatory, nervous and immune systems of the animals. In order to reduce the harmful effects of high temperatures in poultry production, vitamin E supplementation is a viable alternative for the sector. Some studies indicate its potential antioxidant effect able to modulate inflammatory responses and physiological adjustments to mitigate the...

Effects de le temperature et du regime alimentaire sur certains parametres de l'immunite cellulaire du loup de mer en elevage

Delaporte, Maryse.

In the context of Pacific oyster C. gigas summer mortality, the present study demonstrated that the reproductive effort reduced not only the energetic parameters (carbohydrates and CEA) but also the immune parameters (concentration, phagocytosis and adhesive capacity of hemocytes). Increasing food supply from 4% to 12% (of oyster dry weight) did not counteract this phenomena as most of the additional energy was dedicated to the gametogenesis processes. However, after the gametogenesis, the 12% diet clearly favored energy storage restoration and hemocyte production. Hemocyte parameters were also modulated by the food quality. Indeed, hemocyte concentration tended to increase 20:5n-3 and/or 20:4n-6 were supplied by micro-algae or artificial diets. When these...

Vaccines for finfish aquaculture: What do we need to know to make them work?

Deschaux, P; Peres, G.

The data showed that antibody response and NK cells activity of a teleostean fish Dicentrarchus labrax (Loup de mer) were maximal when animals were bred at a temperature equal to 18 degree C. A proteinoprive diet enhanced T cytotoxic response and diminished NK cell activity. A fast of 15 days had no effect on these two cellular responses.

Aquaculture still faces serious economic impacts due to the loss of animals to disease. A conservative estimate of 5% losses due to disease means that the finfish aquaculture industry loses over $1 billion annually on a global scale. One proven way to prevent costly disease outbreaks is to vaccinate fish against common or known pathogens. Current vaccination schemes still result in losses, however, and this may be due in part to vaccine design. Vaccines are currently designed using state of the art knowledge of immune responses, which is based primarily on mammalian studies. Just how applicable is this information to fish immunity and vaccine design, however? This review discusses what is currently known for teleost fish about two key processes that drive...

Abstract: The objective of this work was to evaluate if the immunosuppressant Sandimmun Neoral enhances the activity of Metarhizium anisopliae against the leaf-cutting ant Atta sexdens. The vulnerability to the pathogen was measured by comparing the mortality rate of worker ants subjected to the following treatments: immunosuppressant+control, immunosuppressant+M. anisopliae, excipient+control, excipient+M. anisopliae, control+M. anisopliae, and control. Worker ants treated with immunosuppressant+M. anisopliae showed the highest mortality rate in comparison with those subjected to all other treatments. The use of the immunosuppressant together with entomopathogenic fungus controlled leaf-cutting ants in laboratory conditions.
