Salmonela em carcaça de aves

The genus Salmonella was characterized in 1885. It is divided into two species and six subspecies or subgenera. Belonging to the family Enterobacteriaceae is composed of Gram-negative rods, usually producing mobile gas from glucose, except in those serovars S. gallinarum and S. Pullorum. Salmonela is one of the biggest problems in public health for its wide occurrence in humans and in animals, where they occupy the center of the epidemiology of enteric salmonelosis. These are responsible for significant rates of morbidity and mortality. Several outbreaks of food transmitted diseases are described involving meat birds. Sources of salmonela in broiler chicks infected stem, feed and farm environment. Currently, S. enteritidis and S. typhimurium are the two most prevalent serovars. In this context, the sum is increased resistance to antimicrobial drugs is including the latest generation of its indiscriminate use in veterinary medicine. This fact represents risk to human and animal health. New strategies have been adopted by the Brazilian poultry industry to control salmonela in broilers, but the contamination by this pathogen is still present in slaughterhouses putting public health at risk

Neuromuscular effects of venoms and crotoxin-like proteins from Crotalus durissus ruruima and Crotalus durissus cumanensis

A myographic study was performed to compare the neuromuscular effects of venoms and crotoxin-like proteins from Crotalus durissus ruruima and Crotalus durissus cumanensis in mice phrenic-diaphragm preparation. It was concluded that both venoms present neurotoxic activity as a consequence of their crotoxin content. Furthermore, crotoxin from C.d. cumanensis is more potent than that from C.d. ruruima venom. At the concentration range in which both venoms express neurotoxic activity, only C.d. cumanensis venom also manifest a direct myotoxic effect that probably involves the synergic participation of other components than crotoxin.

Differentiation and species status of the Neotropical yellow-eared bats Vampyressa pusilla and V. thyone (Phyllostomidae) with a molecular phylogeny and review of the genus

A systematic re-evaluation of Vampyressa pusilla warrants the elevation of V. p. thyone from subspecies to species rank based on its distinction from the allopatric V. p. pusilla. Morphological, mensural, chromosomal, and mitochondrial differences define each of these two taxa as divergent lineages. Vampyressa pusilla is endemic to the Atlantic Forest of southeastern South America and V. thyone is found allopatrically in northwestern South America, Central America, and southern Mexico. A molecular phylogenetic analysis of the mtDNA ND3-4 gene region using restriction endonuclease cut sites resulted in a monophyletic, although weakly supported Vampyressa ingroup with Chiroderma, and a clade of Mesophylla and Ectophylla as successive basal outgroup lineages. The phylogeny within Vampyressa, with the exception of V. melissa which is most similar to V. thyone based on karyotypes and morphology, had a topology of ((pusilla + thyone) + ((brocki + nymphaea) + bidens))).

Seasonal vatiations of the chemical composition of Brazilian propolis

The seasonal variations in the chemical composition of Brazilian propolis, collected by two bee subspecies, Africanized Apis mellifera and European Apis mellifera ligustica, have been investigated by GC and GC-MS. The main components of the samples were phenolic compounds, especially cinnamic acid derivatives, the only exception being the autumn sample from Apis mellifera ligustica, where diterpenes predominated. In propolis from both subspecies, diterpenes appeared in summer and reached maximum percentage in autumn, but were absent during the other seasons. The results obtained indicated that both bee subspecies collect propolis from among the same group of plants, and that there are at least two important plant sources, but these remain unidentified.

Isolamento e identificação das micobactérias em águas tratadas provenientes do sistema de abastecimento de Araraquara-SP

Water quality is very important for the health and the population welfare, and the public supply system must provide water quality and suffi cient quantity for the entire population. Water treatment stations, are the main way to obtain water quality. When this doesn’t occur, several problems can affect the population, in this case, using water with poor quality is a constant risk of emergence causing various diseases. The elimination of microorganisms in treated water reduces competition, encouraging the multiplication of chlorine resistant bacteria as Mycobacterium genus frequently isolated from treated and chlorinated water. Considering the lack of indication from examinations of mycobacteria routine laboratory for quality control of drinking water and other human uses, the objective was to verify the presence isolate and identify the environmental mycobacteria in the system water source surface of Araraquara - SP. We analyzed 40 water samples, distributed as follows: ten water gross collected at Station Water Treatment Plant (WTP), harvested after ten fi ltration; ten collected in the reservoir after chlorination and ten in the network distribution. Were recovered 43 isolates of mycobacteria. All isolates were subjected to PCR-PRA. The mycobacteria were identifi ed as M. lentifl avum, M. parafortuitum, M. genavense, M. gordonae, M. fortuitum, M. confl uent, M. duvalii, M. avium subspecies paratuberculosis and M. szulgai. With these results, was concluded that water is an important source of environmental mycobacteria probably related to several human diseases, suggesting the carrying out continuous monitoring of the microorganisms in the system drinking water.

Infecção por strigea falconis em buteo magnirostris no Brasil

Background: Buteo magnirostris, popularly known as roadside hawk belongs to the family Accipitridae, Ciconiiformes. The specimen is common throughout Brazil inhabiting open areas, tolerating disturbed areas very well, but avoiding dense forests. The trematodes are common parasites in the intestines of birds of prey, with scant notice of pathogenic infections. However, severe infections of trematodes Strigeidae family have been previously reported as a cause of anemia, diarrhea, enteritis, weight loss and death. This paper aims to report the occurrence of infection in S. Falconis in B. magnirostris diagnosed by post mortem examination. Case: The specimen of B. magnirostris, male, young was sent for necropsy at the Laboratory of Veterinary Pathology, Federal Rural University of Semi-Arid (UFERSA), Mossoró-RN, Brazil. With a history of apathy, anorexia, diarrhea and death in one course of 24 h. The free bird life and even puppy had been captured for training and practice of falconry shortly before the clinical manifestation of infection (time of captivity uninformed). On physical examination ruffled feathers, cachexia and pallor of skeletal muscle was observed. At necropsy there was severe enteritis with petechiae and accumulation of liquid contents into the duodenum. Fifty-two trematodes were found set in duodenal mucosa. The other organs and structures showed no changes. Fragments of all organs were harvested, fixed in 10% formalin buffered, routinely processed for histopathology and stained with hematoxylin and eosin (HE). Parasites were carefully collected, washed in saline, fixed, processed and identified according to the morphology and taxonomy. Histologically, the lesions were restricted to the duodenum and were characterized by melting, severe atrophy and necrosis of the epithelial cells of the intestinal villi; inflammatory infiltrate (consisting of lymphocytes, plasma cells and eosinophils) in the lamina propria, in addition to trematodes infiltrated the mucosa and lamina propria. These were 60-80 mm in diameter, consisted of parenchymal body enclosed by the integument. In some cross sections of the parasite was possible to observe the presence of cecum, testis and uterus, with some variations between sections; there were also yellowish eggs and coated with a delicate membrane. The trematodes contain approximately 1 mm in length and used as morphology and taxonomy has been identified as S. Falconis. Discussion: S. Falconis is a trematode intestinal parasite of birds of prey, with reports of its occurrence in Europe, North America and Central. In neotropical regions is described the occurrence of the subspecies S. Falconis brasiliana. Although the absence of clinical signs is a common pattern, parasitism by trematodes may become evident, common to captivity stress conditions, and thus infections, even for low pathogenic parasites can cause diarrhea, anorexia, weight loss and death, as reported in this paper. A factor that possibly contributed to the scant notice is its small size, which makes the observation of this parasite in analysis of necropsy in non-pathological conditions and also not familiar with the technical laboratories in the morphological shape of the eggs, which creates difficulty in finding the parasite in parasitological analysis in captive animals. Despite being considered poorly pathogenic trematodes, epidemiologically, the presence of the parasite should be considered a health risk to free-living predators, newly captive in parks, zoos, veterinary hospitals, triage center for wildlife and creators, as they may express pathogenicity in immunosuppressed animals. This work contributes to recording the presence S. falconis parasitizing the duodenal mucosa of B. magnirostris in Brazil.
