Respiratory tract diseases are responsible for major economic losses in the poultry industry. Avian metapneumovirus is a pathogen that causes acute infections in the upper airways of turkeys and chickens, is associated with Swollen Head Syndrome, and generates variable morbidity between 1% and 20% in chickens. Turkey Rhinotracheitis has a morbidity of up to 100%. The frequent presence of secondary agents or infections associated with other microorganisms can aggravate the syndrome. The clinical diagnosis itself is not sufficient to determine metapneumovirus infections since the disease can be confused with other respiratory problems. Serological methods such as seroneutralisation, immunofluorescence and ELISA, immunohistochemistry, virus isolation from embryonated eggs or tissue cultures and PCR are the main techniques used in the diagnosis of avian metapneumovirus infections. Therefore, a laboratory diagnosis confirming the presence of this pathogen is necessary. Currently, several methods are available, with varying applications and sensitivity. This work describes the current diagnostic methods and presents their advantages and limitations.

Objetivou-se realizar uma breve revisão sobre as características desejáveis a serem buscadas em um programa de melhoramento de milho forrageiro, levando em consideração a qualidade da fibra, a textura do grão e a época de semeadura. A planta de milho para produção de silagem é a que apresenta elevada produção de grão com alta disponibilidade de amido e alta digestibilidade de fibra, produção de massa. No Brasil predominam genótipos de milho com grão tipo flint (duro), e isto é indesejável para produção de silagem devido à baixa digestibilidade do amido, a disposição físico-química dos grânulos de amido é a responsável por esta menor digestibilidade quando comparada aos grãos tipo dentados. Outro ponto a ser considerado é a época de semeadura sendo que cada região bem como cada cultivar de milho tem suas características climáticas próprias as quais devem ser respeitadas para que o genótipo consiga expressar sua produção e qualidade. Desta forma, textura do grão bem como relação colm...

Bats, from the Molossidae family, are found on all continents. Molossus rufus, are found in Brazil, having an insectivorous feeding habit. The present study aimed to characterize and locate the myenteric plexus in the gastrointestinal tract of Molossus rufus bats from the northwest region of the state of Paraná. Necropsy of five male specimens was performed and the structures corresponding to the stomach and intestines were fixed in 10% neutral buffered formalin for histological preparation of the material, and 0.5cm of each segment was followed for identification of myenteric ganglia using the technique of Giemsa and the histochemistry of NADPH-diaphorase. The myenteric plexus is found between the circular and longitudinal strata of the tunica muscularis, with neurons gathered in ganglia surrounded by bundles of collagen fibers. The ganglia observed in the membrane preparations were formed by different numbers of neurons, interconnected by bundles of nerve fibers, where isolated ne...

The increased production of mechanically separated poultry meat has led to its use in the production of foods of higher commercial value, such as hamburgers. However, hamburgers are more susceptible to oxidation, therefore, the goal of this study was to evaluate the antioxidant and antibacterial properties of hamburgers made with mechanically separated meat (MSM) from broilers and broiler breeder hens supplemented with oregano (Origanum vulgare) or peppermint (Mentha piperita). Hamburgers with a synthetic antioxidant and three levels of oregano and peppermint essential oils were evaluated using a sensory acceptance test. An inclusion level of 0.04% for both essentials oils was chosen for this test to evaluate the physical-chemical compositions as well as the microbiological and antioxidant activities because an inclusion level of 0.08% received a lower score from the evaluators. Higher pH values were found in hamburgers made with broiler MSM (control (6.94) and peppermint essential ...

Taking into account the increasing search for quality milk production, the objective was to evaluate the milk quality of 33 properties located in the northwest region of Paraná in 2018, relating them to current legislation (normative instruction 76). The results of standard plate count (SPC), somatic cell count (SCC), fat, non-fat solids, total solids, lactose and protein were tabulated. There was non-compliance related to the legislation of 53% of the samples for SPC and 21.8% for SCC. In the analysis of geometric means, 27.3% presented three consecutive months above the acceptable limits for SCC and 63.6% for SPC. The multiple correspondence analysis of the nonconformity results showed two processes involving, each, three strongly associated variables: SCC, fat and total solids and SCC, lactose and total solids. These associations came from 56.3% of the variability contained in the data set, demonstrating that high SCC results negatively affect the percentages of fat and total sol...

Pelas características anatômicas e fisiológicas dos rins, a lesão renal aguda tem sua origem nefrotóxica pela alta circulação local, o que favorece a alta concentração de substâncias tóxicas e seus metabólitos no tecido. A lesão renal aguda é uma complicação comum em internações hospitalares e principalmente em internações em unidades de terapia intensiva. A ciclofosfamida, um quimioterápico utilizado no tratamento de doenças autoimunes e neoplasias sólidas, pode causar nefrotoxicidade com disfunção glomerular e tubular. O uso de plantas medicinais, pelas suas potentes ações antioxidantes, tem sido usado para prevenção ou tratamento de lesões celulares induzidas pelo desequilíbrio entre enzimas antioxidantes e oxidantes. Por esse motivo, o objetivo do experimento foi avaliar o potencial efeito protetor da Echinodorus grandiflorus na prevenção da nefrotoxidade induzida pela ciclofosfamida. Para isso, foi realizado o experimento com a utilização de 35 ratos machos, Wistar, divididos e...

A patogenia de Salmonella em peixes é desconhecida e diversas são as formas de contaminação do pescado por este microrganismo, sem relatos que esclareçam sua função como agente etiológico ou como pertencente à microbiota destes animais. Em diversos países esta bactéria é responsável por milhões de casos de Salmonelose e as salmonelas paratíficas são as principais causadoras de doenças associadas ao consumo de peixes e crustáceos. Vários fatores podem influenciar na segurança dos alimentos da aquicultura, como o tipo das espécies cultivadas, localização dos criadouros, práticas de cultivo e manejo, preparo e consumo do pescado. Além disso, a escassez de saneamento básico ou disposição de rejeitos animais e humanos de forma inapropriada contribuem para a poluição desses ambientes. A contaminação do ecossistema aquático por Salmonella torna o ambiente uma fonte de disseminação desta bactéria. A crescente expansão da aquicultura como fonte de alimentos reforça a importância de um sistem...

ABSTRACT: Coturniculture has been promising, progressing from a subsistence to a technical activity due to its quick production, low breeding investment, and rapid economic return. After the restriction of antimicrobials as growth promoters, some studies aimed to evaluate alternative products that would make the farming of healthy birds viable without impacting their performance, with commercial Macleaya cordata extract being one of these substitutes. The functions of the gastrointestinal tract are coordinated mainly by the enteric nervous system, and the myenteric plexus is responsible for the reflex control of contractile activities of the external muscles. Thus, this study located and demonstrated the distribution of the myenteric plexus, quantifing the total population of myenteric neurons (Giemsa+) and the subpopulation of myenteric nitrergic neurons (NADPH-d+), and evaluated the effects of commercial Macleaya cordata extract on these populations of quail jejunum neurons. A tot...

This study aimed to identify the main reasons for condemnation of broilers slaughtered under the Federal Inspection Service. Data from the Federal Inspection Service from a poultry slaughterhouse located in the northwest of Parana, in the period from January 2011 to October 2012, were used. A total of 16,684,646 birds coming from municipalities located in the region were inspected. From these, 1,344,473 animals had some sort of post-mortem condemnation. The main causes for condemnation (total and partial) were grouped according to the largest number of condemnations. Among the total number of post-mortem condemnations in 2011, 97.93% was due to partial condemnation, and 2.07% due to total condemnation. In 2012, the percentage of post-mortem condemnations due to partial condemnation was 97.91%, and 2.09% due to total condemnations. The most frequent causes of total condemnation were repugnant aspect (47.33%) and inadequate bleeding (23.09%). On the other hand, the most frequent cause...

Os suínos são a segunda proteína animal mais consumida do mundo, sendo que o Brasil é o quarto produtor mundial deste tipo de carne. Uma das técnicas utilizadas para melhorar a palatabilidade e a aceitação pelo consumidor da carne suína é a castração de machos. Além de melhorar o sabor e palatabilidade da carne, a castração em suínos machos também é realizada para facilitar o manejo. Diante do exposto, o objetivo desta revisão é discorrer sobre as principais técnicas utilizadas para castrar suínos machos. No Brasil, a castração de machos suínos é realizada principalmente por métodos cirúrgicos (orquiectomia), geralmente aos sete dias de vida do animal e é praticada sem anestesia. Dessa forma, a orquiectomia em suínos da maneira que é realizada fere os princípios de bem-estar animal. No entanto, para praticá-la com bem-estar e segurança o custo é alto para o pequeno produtor, que é maioria no Brasil. Uma das alternativas à castração cirúrgica de suínos machos e que atende às normas d...

Losses due to low reproductive efficiency can economically affect production in a small dairy farm. The aim of this study was to detect the presence of anti-Leptospira, anti-Toxoplasma gondii, and anti-Neospora caninum antibodies in dairy cows with history of reproductive problems at a small dairy farm in Umuarama, Paraná, Brazil. The evaluated herd presented with history of abortion and return to estrus. Of the 37 samples analyzed, 10 (27%) were positive in microscopic serum agglutination, with titers ranging from 100 to 400, 21 (56.75%) were positive for Toxoplasma gondii in the indirect immunofluorescence test (IIFT), with titers ranging from 16 to 256, and four (10.8%) were positive for Neospora caninum in IIFT, with titers ranging from 25 to 50. No variables were associated with any infection. Leptospirosis, toxoplasmosis, and neosporosis are widespread in herds and may have a negative impact on reproductive parameters of dairy cattle.

The indiscriminate use of antibiotics in veterinary medicine and their negligent use among dog owners have contributed to the rise of antibiotic resistance in microorganisms found in pets. In addition, the search for medicinal plants with antibacterial properties has made the evaluation of aqueous extracts of Alpinia purpurata (Vieill.) K. Schum an important issue. Thus, the aim of this work was to determine the antibiotic resistance profile of gram-negative bacteria isolated from nasal swab samples of dogs and assess the antibacterial activity of the aqueous extracts of leaves and rhizomes of A. purpurata. The bacteria identified were tested using the agar disc diffusion assay for the evaluation of antibiotic resistance. A total of 16 isolates were obtained from the 19 samples collected, with a high prevalence of Escherichia coli (n=5). There was a high rate of resistance to ?-lactams, where the highest percentage was seen for amoxicillin (72.5%). Aqueous leaf extracts had high lev...

This work was carried out to evaluate the effect of different particle size corn on the performance, egg quality and intestinal morphology of Hisex Brown laying hens. A total of 128 birds were used, in a completely randomized design with four treatments, four replicates and eight birds per experimental unit. Experimental rations had corn with different particle size: 565, 620, 781 and 1085 μm of mean geometric diameter (MGD). Feeding was ad libitum at 8:00 am and 4:00 p.m. The variables analyzed were: feed consumption, laying percentage, egg mass and weight, food conversion (was calculated by dividing the feed consumed by the total egg weight (kg.kg-1) and the number of eggs produced (kg.dozen-1)), shell percentage and thickness, Haugh unit, yolk color index and morphometry analysis of the intestinal mucosa. The use of corn with MGD until to 1085 μm in rations does not affect the performance and eggs quality of Hisex Bronw laying hens. However, there are indications that the intesti...

ABSTRACT: The use of antimicrobials in fish farming is a reflection of the fast aquaculture development worldwide. The intensification of aquaculture to achieve market demands could lead to an increase in infectious diseases by pathogenic bacteria. Consequently, antimicrobials act as controls for emerging infectious diseases, but their use must follow the rules and regulations of the country where the activity is performed. Although the regulations impose limits to the use of antimicrobials in fish farming, many studies show that resistant bacteria are isolated from this system. The selection of resistant bacteria is not limited only to the use of antimicrobials, but also to co-selection of resistance genes or even with cross-resistance processes. Resistant bacteria from fish farming are a serious concern because they can be acquired by humans with handling or food chain, which may represent a public health problem. In the present review, we present an overview of antimicrobials use...

The plant species Baccharis trimera presents antioxidants that may have neuroprotective effects on the neurons of the myenteric plexus. Thus, the aim of the present study was to investigate possible quantitative alterations in the myenteric plexus neurons and in the glycemic and lipid profile of 25 rats with 90 days old, exposed to smoking, a hypercholesterolemic diet, and with diabetes mellitus induced by streptozotocin during four weeks, and then treated with different doses of carqueja extract for two weeks. The myenteric plexus neurons were stained with basic Giemsa and using the NADPH-diaphorase histochemistry protocol. In the study conditions, there was a significant reduction in the number of total neurons between the groups treated with carqueja and the positive control, stained with the Giemsa. In contrast, there was no significant difference in the number of neurons of the inhibitory subpopulation between the groups treated with carqueja and the negative control, evidenced...

The functionality of nutraceutical foods is attributed to their bioactive compounds. These compounds are widely produced by plants, such as phenolic compounds, which have antioxidant activity and/or antimicrobial activity, acting against damage to macromolecules such as lipids, proteins, and nucleic acids. Secondary plant metabolites, including classes such as phenolic compounds, alkaloids, and terpenoids, have a wide variety of biological activities with medicinal potential. These secondary metabolites are considered bioactive compounds. The Zingiberaceae family received special attention for their large bioactive compound production. Such compounds are useful in foods as herbs, spices, flavorings, and seasonings and in the pharmaceutical and cosmetic industries as antioxidants and antimicrobials. Gingers are recognized as safe by the American Food and Drug Administration (FDA), resulting in no side effects when consumed in moderate amounts. Recent studies show that, in addition to...

ABSTRACT: The aim of this paper was to conduct a bibliometry search about Brazilian scientific publications that describe experimental orthopedic surgeries in dogs. It was analyzed 14 publications, and there was wide variation in the number of experimental animals, showing that there is no consensus on the appropriate number for science experiment with dogs. Most articles had been reviewed by an ethics committee (13/14, 92.85%) and only two articles (2/14; 14.28%) did not report the use of analgesic protocol. Among analgesics, morphine was the most widely used, noted in seven studies (7/14; 42.85%). In six of the articles (6/14; 42.85%), the final destination of animals was not informed, but in four experiments (4/14; 28.57%) the dogs were euthanized. In four studies (4/14; 28.57%) the animals were sent for adoption. In conclusion, the ethics in animal research in Brazil has advanced, but is necessary proper planning in sample size.

Devido ao uso de antibióticos para o tratamento e prevenção de infecções bacterianas durante a produção de matrizes pesadas, torna-se importante estudar o perfil de resistência e a prevalência de bactérias gram-negativas produtoras de ESBL. Dentre as várias classes de antimicrobianos disponíveis, destacam-se os agentes beta-lactâmicos, categoria antimicrobiana amplamente utilizada em clínica médica humana e veterinária. Assim, este trabalho teve como objetivo avaliar o perfil de resistência e caracterizar as cepas produtoras de beta-lactamases de espectro estendido (ESBL) isoladas de matrizes de corte por meio da coleta de 87 swabs cloacais. As bactérias Gram-negativas foram isoladas em meios seletivos, identificadas por métodos bioquímicos convencionais e MALDI-TOF® e estudadas quanto à resistência antimicrobiana, incluindo ESBL. Das 87 amostras, foram isoladas 52 bactérias gram-negativas. Houve alta resistência bacteriana às principais classes de antimicrobianos utilizados em aves...
