Abstact: Canine visceral leishmaniasis (CVL) is a disease that affects dogs, with a wide range of clinical signs and various alterations in the abdominal organs, with the kidneys
being the most affected. In order to properly stage the disease and make the best therapeutic
choice, renal assessment should be carried out using ultrasound, biochemical tests and blood pressure profiles. The aim of this study was to compare renal aspects using B-mode
ultrasound and vascular Doppler, biochemical tests, urinalysis and blood pressure in Leishmania sp. positive dogs treated with miltefosine at different stages of treatment. To this
end, 38 dogs over the age of one year were used, distributed as follows: 12 healthy dogs (G1), 26 dogs naturally infected with Leishmania sp., of which 12 were positive and not treated with miltefosine (G2) and 14 were treated with miltefosine (G3). Evaluations were carried out twice, 30 days apart, where a complete blood count, urea (U) and creatinine (C)
levels were taken. Urine was collected by cystocentesis for urinalysis and urinary protein/creatinine ratio (UPCR). Blood pressure was measured using vascular Doppler. The Doppler resistivity index (RI) of the renal arteries was obtained at the same time as the B-
mode ultrasound assessments. After the laboratory tests, serum U levels were observed with
an average value of 39.7 mg/dL, with no statistical difference between the groups. Serum C levels averaged 0.92 mg/dL, with a statistical difference between G1 and G2. The average blood pressure values were 118 to 144 mmg, with G2 having the lowest measurement (135
to 140 mmg) and a statistical difference between the other groups. After urinalysis, urine density ranged from 1024 to 1030, with no statistical difference between the groups. With
the RPCU, values ranging from 0.3 to 2.2 were obtained, with the highest value in G3. In
Doppler velocimetry, systolic velocity (SV) values ranged from 42.4 to 60.2 cm/s for the
right kidney and 45.97 to 60.1 cm/s for the left. Diastolic velocity (DV) ranged from 14.5 to 21.3 in the right kidney and 15.8 to 19.8 in the left. Resistivity index (RI) measurements ranged from 0.66 to 0.68 for the right kidney and 0.65 to 0.68 for the left, with no statistical
difference between the groups. Even with some ultrasound and hemodynamic changes, the urea and creatinine values were within the normal range for the species. The IR averages showed no difference between the treated and untreated animals. The positive animals not
treated with miltefosine had higher blood pressure values than the negative and treated animals. The patients treated with miltefosine were proteinuric with reference values higher than normal.2023-10-31T00:00:00ZProdução e comercialização de carne bovina em abatedouro frigorífico sob regime de inspeção municipal, São Luís-MAhttps://repositorio.uema.br/jspui/handle/123456789/62272026-06-26T14:09:54Z2025-01-01T00:00:00ZTítulo: Produção e comercialização de carne bovina em abatedouro frigorífico sob regime de inspeção municipal, São Luís-MA
Abstact: Beef cattle production plays a fundamental role in the Brazilian economy, standing out for its
expressive production and commercialization of beef. In the state of Maranhão, this activity has
regional relevance, with strong dependence on extensive production systems and the operation
of slaughterhouses supervised by the Municipal Inspection Service (SIM), which are
responsible for supplying the local market. Therefore, this study aimed to analyze the beef
production process and the commercialization structure in a slaughterhouse under municipal
inspection in São Luís, Maranhão, Brazil. The research was characterized as descriptive,
observational, and quantitative, carried out through on-site monitoring of the slaughter routine
from October 22 to November 14, 2025. The slaughtering stages, the profile and origin of
slaughtered animals, hot carcass weights, and commercialization models adopted by the agents
involved in the production chain were evaluated. During the study period, 717 cattle were
slaughtered, with a predominance of females, mainly heifers and cull cows, originating from
different municipalities in Maranhão, especially from the Médio Mearim region. Hot carcass
weights ranged from 170 to 300 kg, with an average of approximately 235 kg, resulting in an
estimated production of 168.5 tons of beef. Commercialization mainly occurred as whole
carcasses, forequarters, and hindquarters, with price differences associated with anatomical and
functional characteristics of the carcass. It is concluded that the studied slaughterhouse plays a
strategic role in local food supply and food safety; however, logistical, structural, and
productive challenges remain, highlighting the need for improvements to increase efficiency
and sustainability in the beef production chain.2025-01-01T00:00:00ZO amendoim como alternativa na alimentação animalhttps://repositorio.uema.br/jspui/handle/123456789/62262026-06-26T13:47:38Z2025-12-17T00:00:00ZTítulo: O amendoim como alternativa na alimentação animal
Abstact: Brazil stands out as one of the world's leading producers of peanuts (Arachis hypogaea L.), with
its production tripling in the last decade. As an ingredient in animal feed, it has attracted interest
due to its high nutritional value, availability in various producing regions, and the possibility of
utilizing agro-industrial waste, promoting sustainability and reducing costs in animal
production. Peanut production generates waste such as: the shell, used for energy generation;
the skin and shriveled kernels, used for oil production; and mineral and vegetable residues from
the crop, which are sent to landfills. Co-products are residues obtained from agro-industrial
processes (alcohol production, fruit juices, grains, crops, and human food) and, because they
have adequate nutritional value to meet animal requirements, can be used in diet formulations,
replacing part of the corn and soybean meal in animal feed. This study aimed to evaluate the
chemical composition of peanuts and their co-products (shell, skin, kernel, and whole peanuts)
for their use in animal nutrition. Laboratory analyses demonstrated that the husk has a high
content of neutral detergent fiber (NDF = 78.3%) and acid detergent fiber (ADF = 65.5%), with
low protein and energy content. The skin stood out for presenting higher levels of crude protein
(CP = 23.7%) and ether extract (EE = 27.9%). The grain presented the highest energy density,
with 26.1% CP and 46.4% EE, while the whole sample presented intermediate characteristics,
balancing energy and fiber (NDF = 58.7%; ADF = 44.2%). It is concluded that peanut by-
products can be used in the formulation of animal diets, provided that inclusion limits and
sanitary precautions are respected.2025-12-17T00:00:00ZOcorrência de enterobactérias em queijos artesanais elaborados a partir de leite de búfala (Bubalus bubalis): impacto para a saúde pública?https://repositorio.uema.br/jspui/handle/123456789/62252026-06-26T13:13:27Z2025-12-23T00:00:00ZTítulo: Ocorrência de enterobactérias em queijos artesanais elaborados a partir de leite de búfala (Bubalus bubalis): impacto para a saúde pública?
Abstact: Brazil has one of the largest buffalo herds in the Western world, with the animals well
adapted to Brazilian edaphoclimatic conditions. Buffalo milk has several peculiarities that
make it very suitable for the production of dairy products, such as cheese. In this context, the
objective was to evaluate the occurrence of enterobacteria in artisanal cheeses made from
buffalo milk (Bubalus bubalis), promoting discussion within the scope of the impact on public
health. To this end, 20 samples of artisanal cheese from the municipalities of São Bento and
Viana, located in the Baixada Maranhense region, were collected and analyzed. In a
laboratory setting, analytical units were removed for isolation using standardized
microbiological techniques and identification of enterobacteria using a commercial
biochemical panel composed of 23 parameters. Enterobacteriaceae were quantified in 100%
of the samples, with bacterial populations ranging from 2.4 x 10³ to 5.68 x 2.02 x 10⁷ CFU/g
for butter cheese and from 6.7 x 10² to 1.59 x 10⁷ for rennet, and 183 bacterial strains were
isolated, identifying 11 different bacterial genera and 18 species of enterobacteria. Among
these, Pantoea agglomerans, Proteus mirabilis, Citrobacter freundii, Enterobacter cloacae,
and Klebsiella pneumoniae subsp. pneumoniae stand out due to their presence in different
environments and their recurrence in human infections. It is concluded that the high
percentages of enterobacterial contamination indicate the need to implement appropriate
hygiene practices and microbiological quality control measures to ensure the safety of
artisanal dairy products, which are suitable to the reality of production, valuing the knowledge
of the producers, but without neglecting the safety of the food produced.2025-12-23T00:00:00Z
