1. Padrão da atividade locomotora e expressão de EAAC1 e GLT1 no córtex pré-frontal e entorrinal de ratos criados em isolamento a partir do desmame / Pattern of locomotor activity and expression of EAAC1 and GLT1 in prefrontal and entorhinal cortex of rats reared in isolation from weaning
Isolation rearing of rats from weaning has been used as an experimental model of psychiatric disorders like schizophrenia. It has been demonstrated that isolation induces morphological, behavioral (like hyperactivity in a novel environment) and neurochemical changes similar to those reported for humans with schizophrenia. Evidence suggest that glutamatergic

2. Isolamento do vírus ectima contagioso e identificação pela reação em cadeia da polimerase. / Contagious ecthyma virus isolation and identification by polymerase chain reaction.
Contagious ecthyma (CE) is an acute viral disease that affects sheep and goats, widespread throughout the world, including Brazil, especially in the Northeast, where sheep and goat rearing is practiced for the production of skin, meat and milk. In the state of Pernambuco, has been reported as one of the major infectious diseases of goats and sheep in semi-ar

3. Effects of stress on catecholamine stores in central and peripheral tissues of long-term socially isolated rats
Both the peripheral sympatho-adrenomedullary and central catecholaminergic systems are activated by various psycho-social and physical stressors. Catecholamine stores in the hypothalamus, hippocampus, adrenal glands, and heart auricles of long-term socially isolated (21 days) and control 3-month-old male Wistar rats, as well as their response to immobilizati

4. Routine post-weaning handling of rats prevents isolation rearing-induced deficit in prepulse inhibition
Rats reared under isolation conditions from weaning present a number of behavioral changes compared to animals reared under social conditions (group housing). These changes include deficits in prepulse inhibition (PPI) of the startle reflex to a loud sound. PPI refers to the reduction of the magnitude of the startle reflex when a relatively weak stimulus (th

5. Test profiles of broiler breeder flocks housed in farms with endemic Mycoplasma synoviae infection
There is a need for a better understanding of the epidemiology of Mycoplasma synoviae (MS) infection in broiler breeders in Brazil. Many features of the infection remain unrecognizable, because there are no clinical signs of the disease. A detailed testing was performed at each 6 to 8 weeks in three MS-free flocks introduced in farms with endemic MS infectio

6. Social Recovery by Isolation-Reared Monkeys
Total social isolation of macaque monkeys for at least the first 6 months of life consistently produces severe deficits in virtually every aspect of social behavior. Experiments designed to rehabilitate monkeys reared in isolation are described. While young isolates exposed to equal-age normal peers achieved only limited recovery of simple social responses,

7. A selective and differential medium for Vibrio harveyi.
A new medium, termed Vibrio harveyi agar, has been developed for the isolation and enumeration of V. harveyi. It is possible to differentiate V. harveyi colonies from the colonies of strains representing 15 other Vibrio species with this medium. This medium has been shown to inhibit the growth of two strains of marine Pseudomonas spp. and two strains of mari

8. Epidemiology of a Herpesvirus of Turkeys: Possible Sources and Spread of Infection in Turkey Flocks
Parameters of turkey herpesvirus (HVT) infection were followed sequentially from hatching through 20 weeks in two commercial turkey flocks. Maternal antibody was uniformly present at hatching but decreased below detectable levels by the 3rd week. Virus was first isolated at the 5th and 6th weeks and thereafter spread rapidly within the flocks. Development of

9. Microbial ecology of Campylobacter jejuni in a United Kingdom chicken supply chain: intermittent common source, vertical transmission, and amplification by flock propagation.
A study of Campylobacter jejuni on a broiler chicken farm between 1989 and 1994 gave an estimated isolation rate of 27% (3,304 of 12,233) from a 0.9% sample of 1.44 million broiler chickens from six to eight sheds over 32 consecutive rearing flocks comprising 251 broiler shed flocks. During the study, C. jejuni was found in 35.5% of the 251 shed flocks but o

10. Experience-Expectant Plasticity in the Mushroom Bodies of the Honeybee
Worker honeybees (Apis mellifera) were reared in social isolation in complete darkness to assess the effects of experience on growth of the neuropil of the mushroom bodies (MBs) during adult life. Comparison of the volume of the MBs of 1-day-old and 7-day-old bees showed that a significant increase in volume in the MB neuropil occurred during the first week

11. Isolation of Bacteriophages Specific to a Fish Pathogen, Pseudomonas plecoglossicida, as a Candidate for Disease Control
Two types of bacteriophage specific to Pseudomonas plecoglossicida, the causative agent of bacterial hemorrhagic ascites disease in cultured ayu fish (Plecoglossus altivelis), were isolated from diseased ayu and the rearing pond water. One type of phage, which formed small plaques, was tentatively classified as a member of the family Myoviridae, and the othe
