Objective: This study aimed to make an inventory of animal diseases that affect milk production and the plants locally used against these diseases. Materials and methods: A survey was carried out from April to August 2013 in 41 farms in department of Collines, 40 in Alibori, 40 in Borgou and 21 in Mono using questionnaires. SAS software was used with Chi-square test and bilateral Z test. Results: The study revealed twelve main pathologies that limit milk production. Among these pathologies, foot-and-mouth disease and trypanosomiasis were the most mentioned pathologies. To fight these pathologies, 60 medicinal plants of 32 families were recorded. The most cited families were Leguminosae (31.67%), Combretaceae (6.67%), Meliaceae (5%) and Rubiaceae (5%), whereas the predominant species used by animal keepers were Khaya senagalensis, Vitellaria paradoxa, Parkia biglobosa and Securidaca longipedunculata. The 60 listed species were used in 85 recipes which varied from one department and farmer to another. The most used organs were plant barks (41.06%) and roots (31.13%), while the most common methods of preparation were decoction (37.5%), maceration (32.5%) and powders (22.5%). Oral route was the main route of administration. Conclusion: The inventory has shown that the important pathologies are foot-and-mouth disease and trypanosomiasis. This needs immediate actions. Barks and roots were the commonly employed plant organs used as infusion (decoction and maceration) and powder that farmers administer orally to animals. The harvest did not require a special season or time. Furthermore, farmers inherited most of these recipes from their parents and they use them because of their effectiveness.

Objective: This study aimed at assessing the prevalence of Helicobacter spp. in ice cream sold at Qena city (Egypt) with special reference to H. pylori, and to study the antimicrobial effect of mastic gum essential oil on H. pylori. Materials and methods: A total of 60 small and large scale ice cream samples (30 each) were investigated for the presence of Helicobacter spp. Then, the essential oil of mastic gum was added to lab prepared ice cream inoculated with H. pylori isolate in a count of Log6 using 2 concentrations of 0.8 and 1.6% and one group was kept as a control group. Each group was subdivided into 2 sub-groups; one was kept at -5°C and another one was kept at -20°C. Results: Helicobacter spp. could be isolated from 11.7%, while, H. pylori could be found in 3.3% of the total examined ice cream samples. Regarding the anti-Helicobacter pylori effect of mastic gum essential oil added to lab prepared ice cream, in samples kept at -5°C it was found that after hardening the count fall into Log5 in both control and 0.8% groups and log4 in 1.6% essential mastic oil concentration. Reduction in H. pylori at the first week and third day of storage reached 100% where H. pylori couldn’t be counted or isolated from both 0.8 and 1.6% concentrations, respectively. While in ice cream samples stored at -20°C, the reduction in H. pylori load was rapid at first, it was log4 and log3 in groups of 0.8% and 1.6% concentrations, respectively versus log5 in control samples. At the third day H. pylori was not able to be counted or isolated at third day of storage for both concentrations. Conclusion: All isolates recovered from small scale ice cream samples reflexing the hygienic conditions under which samples were produced. Mastic gum essential oil exhibited a powerful anti-H. pylori effect recommending its addition to food matrix for therapeutic purposes or as a functional food.

Objective: This study was conceived to investigate the pathogenicity of relapsed (Diminazene aceturate-resistant), field (original) and mixed (relapsed and field) isolates of Trypanosoma brucei brucei in rats. Materials and methods: Twenty eight healthy adult albino rats of both sexes weighing between 149-177 gm were used to compare the pathogenicity of relapsed, field and the mixed isolates of T. brucei brucei infections. The rats were separated into four groups (A-D); where, group A was kept as uninfected control, and group B was infected with 1x103 trypanosomes of the field isolate and 1x103 trypanosomes of the diminazene aceturate resistant isolate. The rats of groups C and D were infected with 1x106 trypanosomes of the diminazene aceturate-resistant isolate and 1x106 trypanosomes of the field isolate, respectively. Results: The infected rats became parasitemic within 4 to 8 days post-infection. The mean pre-patent periods (PP) were 4.1&plusmn;1.1, 6.0&plusmn;2.0 and 9.1&plusmn;1.1 days in groups B, C and D respectively, while the mean survival time (ST) in groups B, C and D were 21.4&plusmn;10.1, 27.1&plusmn;13.2 and 34.0 &plusmn;12.8 days, respectively. The PP and ST were shortest (P<0.05) in group B (mixed infections), and level of parasitemia was higher (P<0.05) in group B (mixed infections) as compared to groups C and D. The level of anemia was comparable (P>0.05) in groups C and D and more severe (P<0.05) in group B. Conclusion: Mixed infections exhibit shortest PP, ST, higher level of parasitemia and more severe anemia, and appear to be more pathogenic. [J Adv Vet Anim Res 2017; 4(1.000): 97-103]

Adrenalectomy is the most appropriate treatment for unilateral adrenal tumors. This study aimed at describing the epidemiological characteristics and perioperative behavior of canine patients submitted to adrenalectomy at Anhembi Morumbi Veterinary Hospital. Out of 13 dogs, eight were pure breeds and five were mixed breeds; 12 females, aged 9.5 ± 2.5 years old. Regarding the tumors, seven were located on the right and histopathological analysis revealed cortical adenoma in 11 and adenocarcinoma in only two dogs. Two cases had hypercortisolism recurrence associated with hyperplasia in the contralateral adrenal, as confirmed by ACTH stimulation test. The results of this study indicate that adrenalectomy is a safe procedure with few perioperative complications, despite the possibility of hypercortisolism recurrence.

Adrenalectomia é o tratamento mais indicado para neoplasias adrenais unilaterais. Objetivou-se descrever os aspectos epidemiológicos e o comportamento perioperatório em cães submetidos a adrenalectomia no Hospital Veterinário Anhembi Morumbi. Dos 13 casos, oito eram cães de raças puras e cinco eram SRD; 12 eram fêmeas e de idade de 9,5 ± 2,5 anos. Das massas adrenais, sete eram em lado direito. Os exames histopatológicos revelaram adenoma cortical em 11 cães e adenocarcinoma em dois. Dois casos recidivaram a condição de hipercortisolemia, associada à hiperplasia, na adrenal contralateral, confirmados pelo teste de estimulação por ACTH. Concluiu-se que a adrenalectomia é um procedimento seguro, com poucas complicações perioperatórias, ressalvando-se a possiblidade de recidiva do quadro de hipercortisolismo. | Adrenalectomy is the most appropriate treatment for unilateral adrenal tumors.

Juvenile cellulitis (JC) is an uncommon vesiculopustular disease that affects dogs, especially those under four months of age. The aim of the present study was to characterize the epidemiological, clinical, and therapeutic profile of JC based on clinical records of canine patients treated at the Veterinary Hospital of the Universidade Federal Rural do Semi-Árido, between the years 2009 and 2016. A total of five cases were diagnosed. Four dogs presented at an average age of two months and 22 days and were crossbred; the other dog was a rottweiler aged 38 weeks. The average time of evolution of the disease was 16 days, and the main clinical signs were edema, papules, pustules, and bilateral ocular discharge. The diagnosis was confirmed by cytology in four animals and by histopathology in only one patient. For all dogs, the treatment was based on cephalexin, administered for 30 days, and prednisolone for three weeks. Otological therapy was included when necessary. Four cases had a favorable outcome. JC is a rare dermatopathy that deserves special attention from veterinary practitioners.

A celulite juvenil (CJ) é uma doença vesiculopustular incomum que acomete cães principalmente na faixa etária inferior aos quatro meses. Este trabalho analisou o perfil epidemiológico, clínico e terapêutico da CJ em cães a partir da casuística do Hospital Veterinário da Universidade Federal Rural do Semi-Árido, referente aos anos de 2009 a 2016. Cinco casos foram diagnosticados, incluindo quatro cães (80%), sem raça definida e com idade média de dois meses e 22 dias, e um da raça Rottweiler (20%) com 38 meses de idade. O período evolutivo médio das lesões foi de 16 dias e os principais sinais clínicos observados foram edema, pápulas, pústulas e secreção ótica bilateral. O diagnóstico foi confirmado por citologia (80%) e histopatologia (20%). Em todos os animais, o tratamento consistiu de cefalexina, administrada por 30 dias, e prednisolona, por três semanas. A terapia otológica tópica foi incluída quando necessária. Em quatro casos o desfecho clínico foi favorável. A CJ é uma dermatopatia rara que merece atenção especial dos clínicos veterinários. | Juvenile cellulitis (JC) is an uncommon vesiculopustular disease that affects dogs, especially those under four months of age.

A cinomose canina é uma das principais doenças infecciosas em cães e animais selvagens, resultando em alta morbidade e mortalidade. O gene H tem uma das maiores variabilidades genéticas entre os genes codificados pelo vírus da cinomose canina (CDV), e tem sido utilizado para caracterizar as estirpes de CDV, permitindo a identificação de linhagens específicas. A variação no gene H pode permitir que o vírus evite o reconhecimento por anticorpos induzidos pela vacina, resultando em falha vacinal. O objetivo deste estudo foi caracterizar o gene H em estirpes de CDV de cães infectados naturalmente no estado de São Paulo. A análise filogenética revelou que as estirpes de CDV brasileiras estão geneticamente relacionadas as estirpes circulantes no Uruguai, na Argentina e na Europa. Não foi encontrada nenhuma evidência da circulação no estado de São Paulo das linhagens América do Sul 2 e 3. O grau de divergência genética entre linhagens selvagens de CDV brasileiras e as estirpes vacinais podem sugerir a possibilidade de falhas vacinais e consequentemente a ocorrência de surtos de cinomose canina.

The H gene has the greatest genetic variability among the genes encoded by the canine distemper virus (CDV) genome, and it has been used to characterise field samples, allowing the identification of specific lineages. Variation in the H gene can allow the virus to evade recognition by vaccine-induced antibodies, resulting in vaccine failure. The purpose of this study was to characterise H gene in CDV strains from naturally infected dogs in the state of São Paulo. The phylogenetic analysis revealed that Brazilian CDV strains were genetically related to the circulating CDV strains in Uruguay, Argentina, and Europe. We found no evidence of South America 2 and 3 CDV lineages circulating in Brazilian dogs. The degree of genetic divergence between wild Brazilian CDV strains and vaccine strains may suggest the possibility of vaccine failures and consequently the occurrence of canine distemper outbreaks.

Large quantities of waste are generated throughout the seafood supply chain. Although this material has a great potential for use (e.g. pharmaceutical industry, animal feed production), if not managed properly it represents an environmental risk. In order to meet the volume, destination, and method of storage of waste of Brazilian seafood supply chain, we got information from 29 companies that have Official Veterinary Inspection (SIF). After the industrialization of seafood only 44% on average of the total raw material is used for human consumption and 59.2% of the unused portion is discarded in landfill.

Grandes quantidades de resíduo são geradas ao longo da cadeia produtiva do pescado. Embora este material apresente um grande potencial de aproveitamento (e.g. indústria farmacêutica, produção de ração), se não for corretamente destinado, representa risco ambiental. A fim de conhecer o volume, a destinação e o método de armazenamento do resíduo produzido pela indústria do pescado no Brasil, 29 empresas de processamento de pescado, sob Serviço de Inspeção Federal (SIF), foram estudadas em todo o país. Identificou-se que cerca de 44% do total produzido é matériaprima utilizada para consumo humano, e 59,2% representa resíduo sem finalidade útil, descartado em lixões. | Large quantities of waste are generated throughout the seafood supply chain.

The objective of this study was to evaluate the incidence of repeat breeder (RB) in crossbred dairy cows submitted to a timed artificial insemination (TAI) and estrous synchronization protocols. Data from 371 heifers and 997 lactating crossbred dairy cows were analyzed. Cows with more than 30 DPP with good uterine condition, no lameness or clinical mastitis, and body condition score ≥ 2.5 were used. The cows were divided between two groups, as: group 1: TAI – those cows with no CL at ultrasound exam that were enrolled in a TAI protocol and group 2: estrous synchronization – all those cows that had CL. The incidences of RB and factors relative to it were analyzed by logistic regression in SAS. The incidence of RB condition was higher in lactating cows than non-lactating heifers (P < 0.001). There was a tendency of RB condition to higher in cows that calved during spring/summer than those calved at autumn/winter season. The parturition condition had no effect on RB incidence (P > 0.001); however, lactation degree influenced the incidence of RB (P <0.001). Repeat breeder condition was greater in lactating crossbred dairy cows than in heifers. Moreover, the presence of RB cows was higher in those from second parity group when compared to those from first, third and four parity groups; on the other hand, parturition condition did not influence the appearance of RB cows in the herd.

O objetivo deste estudo foi avaliar a incidência vacas repetidoras (VR) leiteiras mestiças submetidas à inseminação artificial em tempo fixo (IATF) e protocolos de sincronização de estro. Dados de 371 novilhas e 997 vacas leiteiras mestiças foram analisados. Vacas com mais de 30 dias pós-parto, boa condição uterina, sem mastite clínica e com escore corporal ≥ 2,5 foram utilizadas. As vacas foram divididas em dois grupos, sendo: grupo 1: IATF – vacas sem corpo lúteo no exame ultrassonográfico e que foram submetidas ao protocolo de IATF, e grupo 2: sincronização de cio – aquelas vacas com corpo lúteo presente. A incidência de VR e seus fatores foram analisados por regressão logística pelo SAS. A incidência de VR foi maior em vacas em lactação em relação às fêmeas não-lactantes (P &lt; 0,001). Ainda, uma tendência de um maior número de VR foi observada naquelas que pariram na primavera/verão quando comparadas às paridas no outono/inverno. O tipo de parto (normal vs. não normal) não influenciou na incidência de VR (P &gt; 0,001), no entanto, foi detectado efeito do número de partos (P &gt; 0.01). Dessa forma, nas categorias animais avaliadas, a incidência de VR foi maior em vacas leiteiras mestiças do que em novilhas. Uma tendência de VR foi observada naquelas que pariram na primavera/verão quando comparadas aquelas que pariram no outono/inverno, ainda a incidência de VR foi maior naquelas de segunda parição quando comparadas as de primeira, terceira ou quarta, ao passo que o tipo de parto (normal vs. não normal) não influenciou sobre a incidência de VR. | The objective of this study was to evaluate the incidence of repeat breeder (RB) in crossbred dairy cows submitted to a timed artificial insemination (TAI) and estrous synchronization protocols.

Cats play an important role as pets in the present society. Thus, the knowledge about their main diseases and causes of death is fundamental to prevent various pathologies. However, when dealing with domestic cats there are very few researches in Veterinary Medicine. The aim of this study is to identify the causes of death of cats through a retrospective study of necropsies in the Animal Pathology Laboratory in the Federal University of Uberlândia (Brazil), in a period of 36 years, in which 350 cat necropsies were conducted. The most frequent causes of death of these animals were digestive system diseases (48 cats – 13.71%), and among them, feline hepatic lipidosis was the most frequent etiology (18.75%). The second most affected system was the respiratory (10.86%) and acute pneumonia, pulmonary edema, and diaphragmatic hernia were the main diseases to cause death of cats with some kind of disorder in this system. Other decease causes were rabies, squamous cell carcinoma, fibrous osteodystrophy, fractures and traumatism, hypovolemic shock, and feline lower urinary tract disease. This type of analysis can provide basic information about the most common diseases in felines, contributing with veterinarians as they adopt control and prevention actions against diseases.

Os gatos apresentam papel relevante como animal de estimação na sociedade atual. Neste sentido, o conhecimento das principais enfermidades e causas de morte desses animais é fundamental para prevenção de várias patologias. No entanto, quanto ao gato doméstico, essas pesquisas ainda são escassas na medicina veterinária. Assim, este trabalho realizou um estudo retrospectivo das causas de morte de gatos registradas das necropsias efetuadas pelo Laboratório de Patologia Animal da Universidade Federal de Uberlândia, em um período de 36 anos, no qual 350 gatos foram necropsiados. As doenças do sistema digestivo foram as mais frequentes (48 gatos – 13,71%) e destas, a lipidose hepática foi a etiologia de maior ocorrência (18,75%). O sistema respiratório foi o segundo mais afetado (10,86%), sendo pneumonia aguda, edema pulmonar e hérnia diafragmática as principais doenças deste sistema responsáveis pela morte de gatos. Outras causas de óbito importantes foram raiva, carcinoma de células escamosas, osteodistrofia fibrosa, fraturas e traumatismos, choque hipovolêmico e síndrome urológica felina. Este tipo de análise pode fornecer informações básicas sobre as enfermidades que mais acometem os felinos de uma determinada região, contribuindo para que os profissionais médicos veterinários passem a adotar as respectivas ações de prevenção e controle. | Cats play an important role as pets in the present society.
