A STUDY OF ASSOCIATION BETWEEN ELISA RESPONSE TO INFECTIOUS DISEASE AGENTS AND CALVING INTERVAL IN CATTLE IN THE TROPICS OF MÉXICO

Lightner, D; Bell, T; Redman, R.

At least six virus diseases are presently known in cultured penaeid shrimp. Each of these six penaeid virus diseases (BP = Baculovirus penaei ; MBV = Penaeus monodon -type baculovirus (including PBV of Australian penaeids); BMN = baculoviral midgut gland necrosis; HPV = hepatopancreatic parvo-like virus; IHHNV = infectious hypodermal and hematopoietic necrosis virus; and REO = reo-like virus of the hepatopancreas) may be comprised by a multitude of individual strains, some of which are highly pathogenic to some penaeids, while being of little importance to others.

Forty eight cows of Holstein-Zebu crosses with at least one completed pregnancy were tested for antibodies to 20 disease agents. The testing was performed within one month (average two weeks) after calving when the IgG level constantly reaches its lowest value during the cows reproductive cycle. The results indicate that increasing levels of IgG against Leptospira interrogans serovar hardjo and Mycobacterium paratuberculosis may be associated with an increased calving interval. Increase in calving intervals could not be explained by age of cows or their genotypic characteristics.

BACKGROUND: The emergency regarding recent immigration waves into Italy makes continued healthcare monitoring of these populations necessary. METHODS: Through a survey of hospital admissions carried out during the last five years at the S. Orsola-Malpighi General Hospital of Bologna (Italy), all causes of admission of these subjects were evaluated, together with their correlates. Subsequently, we focused on admissions due to infectious diseases. All available data regarding foreign citizens admitted as inpatients or in Day-Hospital settings of our teaching hospital from January 1, 1999, to March 31, 2004, were assessed. Diagnosis-related group (DRG) features, and single discharge diagnoses, were also evaluated, and a further assessment of infectious...

Stomatitis is a common disease found on snake farms, and Gram-negative bacilli are the main etiological agents that play an important role as secondary sources of viral or parasitic infections. The purpose of this work was to identify the aerobic bacteria in the oral cavity of Bothrops atrox with stomatitis. Samples for microbiological examination were collected from 12 snakes bred on a commercial snake farm for venom extraction. Samples of the secretion in the oral cavity of each serpent presenting stomatitis were collected from fang sheath, using a cotton swab with sterile alginate. The samples were incubated and cultured on Petri dishes containing blood agar and XLD agar using the agar depletion technique. Bacterial growth occurred in all analyzed...

Une souche de Pseudomonas cepacia, designée K2, isolée à partir de la palourde Ruditapes decussatus a montré une activité antibactérienne significative contre un certain nombre de bactéries marines, y compris Aeromonas hydrophila, Aeromonas salmonicida et Vibrio anguillarum qui sont les bactéries pathogènes les plus fréquemment signalées dans l'environnement marin, responsables d’une forte mortalité des poissons et des crustacés. Cette souche K2 a montré une capacité d’inhibition très rapide dès le début de sa croissance (après 8h d'incubation). L'intensité de son activité est très importante et a tendance à augmenter avec le temps d'incubation. Les études préliminaires sur la nature de l'inhibition a indiqué qu'au moins l'une des substances...

Appearance and spread of diseases among bivalve molluscs in the northern hemisphere in relation to international trade

Determinación de moléculas que intervienen en el sistema inmune del camarón blanco (Penaeus vannamei) en respuesta al uso de inmunoestimulantes.

Renault, Tristan.

Bivalve mollusc culture is a well-developed marine aquaculture activity in many countries around the world, notably in the northern hemisphere. During the development of this activity, numerous countries have been confronted with infectious diseases of varying severity and duration. Research has been conducted to determine the aetiology, epidemiology and control measures for these epizootics. Major epizootics in bivalve molluscs have been caused by viruses, bacteria, fungi and protozoan parasites. Moreover, important commercial relations exist in marine mollusc culture between different geographical areas. This must be taken into account in explaining the appearance and the spread of some infectious diseases in several countries around the world. The...

La acuacultura de crustáceos penaeidos constituye una actividad económicamente importante que genera elevados ingresos si se garantiza una producción óptima del mismo. Esta actividad está limitada en diferentes partes del mundo por enfermedades infecciosas provocadas entre otros, por bacterias, virus, hongos, parásitos y por el uso regular de antibióticos que han dirigido progresivamente a las poblaciones de cultivo a una situación crítica de resistencia. El estudio del sistema inmune en crustáceos comienza a ser una herramienta muy útil para el diseño de estrategias que permitan determinar y mejorar la respuesta del sistema de defensa del hospedero hacia los patógenos potenciales. Para ello, es requerido que las investigaciones básicas estén dirigidas a...

Diseases of cultured molluscs in Australia

Dried blood spot testing for the antenatal screening of HTLV, HIV, syphilis, toxoplasmosis and hepatitis B and C: prevalence, accuracy and operational aspects

Lester, R.

Three mollusc species are cultured commercially in Australian tropical and warm temperate waters: the Sydney rock oyster Saccostrea commercialis , the pearl rock oyster is susceptible to two protozoans: Marteilia sydneyi , which is the cause of QX Disease and infects oysters during the summer; and Mikrocytos roughleyi which is associated with winter mortality. It also harbours mudworm, Polydora websteri a parasite farmers try to avoid by growing oysters on racks. Transported pearl oysters Pinctada maxima die with heavy infections of Vibrio harveyi . Cultured giant clams Tridacna gigas are pestered by pyramidellid snails and some carry Perkinsus sp., a protozoan common in reef bivalves. Deaths in mollusc hatcheries have been associated with Vibrio tubiashi...

Tissue factor is a transmembrane procoagulant glycoprotein and a member of the cytokine receptor superfamily. It activates the extrinsic coagulation pathway, and induces the formation of a fibrin clot. Tissue factor is important for both normal homeostasis and the development of many thrombotic diseases. A wide variety of cells are able to synthesize and express tissue factor, including monocytes, granulocytes, platelets and endothelial cells. Tissue factor expression can be induced by cell surface components of pathogenic microorganisms, proinflammatory cytokines and membrane microparticles released from activated host cells. Tissue factor plays an important role in initiating thrombosis associated with inflammation during infection, sepsis, and organ...

ABSTRACT: Felis catus gammaherpesvirus 1 (FcaGHV1) may causes an asymptomatic infection that result in an efficient transmission and subsequently dissemination of the virus in feline population. This study used molecular detection by qPCR (quantitative PCR) based on DNA polymerase gene fragment amplification to evaluate the occurrence of FcaGHV1 and its correlation with other feline viral pathogens, such as Carnivore protoparvovirus 1 (CPPV-1), Felid alphaherpesvirus 1 (FeHV-1), and feline retroviruses such as feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV). Of the 182 blood samples evaluated 23.6% (43/182) were positives for FcaGHV1. Approximately 37.9% (33/87) of the samples that tested positive for retrovirus were also were positive...

Many studies have tried to identify genetic markers for infectious diseases, some of them have focused on human leukocyte antigens (HLA). The products of HLA genes interact with surface-specific receptors of T lymphocytes, resulting in activation of the host's immune response. Association of bacterial, viral, parasitic and fungal infections with the host's HLA has been widely investigated. The type and strength of this association differs among distinct populations, as well as among racial and/or ethnic groups. The new molecular methods for the identification of the HLA alleles, and the resulting new nomenclature, have contributed to a better understanding of this system. Unfortunately, this information has not been adequately transmitted to clinicians,...

L'adaptation ecophysiologique et sanitaire de l'ecrevisse turque Astacus leptodactylus a des milieux saumatres: Contribution a l'astaciculture

Mialhe, Eric.

Development of aquaculture has been linked to zootechnical mastering of larval production in hatcheries. Regular and excessive use of antibiotics (antifungal or antibacterial) may thus also be reduced, permitting to limit release of these products in sea-water and, consequently, avoiding progressive selection of resistant-strains.

This influence of salt media on different aspects of biological cycle and on most common pathogenic agents of Turkish freshwater crayfish Astacus leptodactylus is investigated survival and growing of juveniles O super(+) and intermediary individuals 1 super(+) are also studied. Total osmotic metabolism and reproduction, have been recorded. It appears that youngest individuals are particularly sensitive to low salinities (7 ppt.). Intermediary ones are more resistant nevertheless salinity does not improve neither survival nor growing. Copulation, laying and pleopod egg fixation are particularly affected by salt waters. The only promising application of salinity parameter on astaciculture could be whether prophylactic or curative treatment with concentrated...

The modern diet doesn't provide the required amount of beneficial bacteria. Maintenance of a proper microbial ecology in the host is the main criteria to be met for a healthy growth. Probiotics are one such alternative that are supplemented to the host where by and large species of Lactobacillus, Bifidobacterium and Saccharomyces are considered as main probiotics. The field of probiotics has made stupendous strides though there is no major break through in the identification of their mechanism of action. They exert their activity primarily by strengthening the intestinal barrier and immunomodulation. The main objective of the study was to provide a deep insight into the effect of probiotics against the diseases, their applications and proposed mechanism of...

Abstract Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus disease, a complex multisystem syndrome in domestic pigs. Despite the significant economic losses caused by porcine circovirus disease, the mechanisms of pathogenesis underlying the clinical findings remain largely unclear. As various reports have highlighted the potential key role of vascular lesions in the pathogenesis of porcine circovirus disease, the aim of this work was to investigate effects of PCV2 infection on vascular endothelial cells, focusing on cell viability and expression of adhesion/junction molecules. PCV2 infection reduced endothelial cell viability, while viral infection did not affected the viability of several other classical cell lines....
