ABSTRACT
It is well known that transporting livestock is stressful for the animals and a primary cause of skin lesions. The effects of transport on the water buffalo (Bubalus bubalis) have not been studied extensively despite reports of high incidences of trauma during and after these mobilizations. The present review article analyzes the frequency of skin injuries suffered by water buffaloes during transport and several key contributing factors. It also discusses the consequences of injuries on the quality of carcasses. Important aspects identified include inappropriate vehicle design that does not comply with the dimensions recommended by international institutions (e.g., height, type of flooring, characteristics of the ramp), handling methods, and the ability of stock people to manage water buffaloes, all of which impact the incidence of injuries. Our analysis of these elements will contribute to identifying critical control points and areas of opportunity while also suggesting strategies to ensure the welfare of these animals during transport and the quality of water buffalo products and by-products.

Background: Buffalo breeding is common in many countries. Buffalo's milk is used in the production of mozzarella, yoghurt, ice cream, and various dairy desserts; meat is preferred in sausage production. The female buffaloes are bred to benefit from their milk and to obtain offspring. These animals, which are not suitable for feeding in barns, generally live in pastures, especially on wet land, and are very difficult to follow. Therefore, diseases occur randomly in slaughterhouses. Studies on genital system problems are very limited. Water buffaloes (Bubalus bubalis) are animals with economic value as many buffalo products are provided. In this respect, inspection and control of female genital disorders is fundamental to ensure good reproductive performance of female buffaloes. The aim of the study was to investigate pathomorphological lesions occurring in the ovaries of water buffaloes which were sent to slaughterhouses. Materials, Methods & Results: A total of 198 ovaries of water buffaloes were collected from various slaughterhouses located in Adapazari, Istanbul, Kocaeli, Samsun and Trabzon cities of Turkey. After macroscopic examination; tissue samples were fixed in 10 % buffered formalin, processed routinely and were stained with hematoxylin-eosin (HE). As a histochemical staining, Masson's trichrome staining was applied to characterize the lesions. Immunohistochemistry (IHC) was performed on 10 % neutral formalin fixed, paraffin-embedded, 4-6-µm-thick sections from ovaries using progesterone receptor (PR) with streptavidin-biotin complex peroxidase (StrepABC-P) method. Histopathologically, follicular cysts (n:147) and luteal cysts (n:22) were seen. While the cyst lumens were sometimes surrounded by granulosa and/or luteal cells, most of them were limited by the connective tissue capsule structure. This capsule structure was shown in blue by Masson's trichrome staining. Hemorrhage was observed in some cystic corpus luteum, diagnosed as corpus hemorrhagicum. In addition, cysts giving papillary extension into the lumen and inflammation of some ovaries were observed. Immunohistochemically, the staining with PR antibody in ovarian cysts showed no immunolabelling around the follicular cyst, while the nuclei of some of the luteal cells forming the luteal cyst had strongly nuclear positivity and slightly cytoplasmic positivity. In the biochemical examination of the fluids obtained from cystic ovaries (n: 37), the average of estradiol was 2.84 ng/mL (min: 0.01 ng/mL, max: 4.30 ng/mL) and progesterone average is 49.09 ng/mL (min: 1.88 ng/mL, max: 254.2 ng/mL). Discussion: Ovarian cysts in buffaloes seem to be among the serious fertility problems as in cattle. Although the exact cause of ovarian cyts has not been determined yet, it is known that the hypothalamic-pituitary-gonadal (HPG) axis is disrupted in cyst formation in general. In this study, the mean estradiol value was within the standard range but close to the lower limit; progesterone value was above the limit. The increase in progesterone level was compatible with the pathogenesis of cyst genesis. Beside this result, staining with PR was positive in the luteal cells that formed the luteal cyst immunohistochemically. In addition, although the hemorrhages observed in the corpus luteum are considered physiological, it should not be forgotten that they can be vital if they rupture. All these results show us the animals sent for slaughtering mostly have serious genital problems threatening their fertility.

A pele é o maior órgão do corpo e pode ser acometida por uma série de processos patológicos. As doenças dermatológicas em geral são um aspecto frustrante na clínica de animais de grande porte. Desse modo, o objetivo deste estudo foi relatar lesões de pele diagnosticadas em búfalos na região do Baixo Amazonas, estado do Pará. Foram avaliados 156 búfalos das raças Murrah, Mediterrâneo e seus mestiços; adultos e jovens, com idade variando de oito meses a nove anos. No exame físico constatou-se que 36,5% (57/156) dos animais apresentavam abscessos no local de vacinação. Destes, 12,2% (19/156) eram abscessos com presença de alopecia e 1,3% (2/156) com fistulação Além disso, 1,3% (2/156) dos animais apresentaram ainda no local de vacinação, feridas ulceradas com presença de secreção purulenta. Identificou-se que 3,8% (6/156) dos búfalos possuíam lesões provenientes da marcação a fogo, com queimaduras, de aspecto crostoso, eritematoso e exsudativo, na região da garupa.; A maioria 64,1% (100/156) dos animais apresentaram corte das orelhas, 1,9% (3/156) apresentaram lesões por penetração de corno e em 1,2% (2/156) observou-se lesão de pele no membro posterior direito. Conclui-se que foi possível diagnosticar diversas lesões cutâneas nos búfalos na região do Baixo Amazonas, sendo o erro no manejo dos animais as principais causas das lesões diagnosticadas. Além disso, houve correlação entre dois grupos de animais avaliados (com e sem lesão).(AU)
The skin is the largest organ in the body and can be affected by a series of pathological processes. Dermatological diseases in general are a frustrating aspect in the clinic of large animals. Thus, the objective of this study was to report skin lesions diagnosed in buffaloes in the region of Baixo Amazonas, state of Pará. 156 buffaloes of the Murrah, Mediterranean and crossbred breeds were taken; Adults and young people, with ages varying from eight months to nine years. On physical examination, it was found that 36.5% (57/156) of the animals had abscesses at the vaccination site. Of these, 12.2% (19/156) were abscesses with the presence of alopecia and 1.3% (2/156) with fistulation. In addition, 1.3% (2/156) of the animals separated at the vaccination site, ulcerated wounds with the presence of purulent secretion. It was identified that 3.8% (6/156) of the buffaloes had the location of the fire mark, with burns, with a crusted, erythematous and exudative aspect, in the croup region. The majority 64.1% (100/156) of the animals separation of the ears, 1.9% (3/156) dissipation by penetration of the horn and in 1.2% (2/156) a skin lesion was observed in any limb posterior right. It was concluded that it was possible to diagnose several cutaneous lesions in buffaloes in the region of Baixo Amazonas, with the error in handling animals being the main causes of the diagnosed injuries. In addition, there was a correlation between two groups of acquired animals (with and without injury).(AU)

Background: Buffalos are very rustic animals that are adapted to adverse conditions, but the lack of adequate managementcan increase the susceptibility of these animals to several diseases. Rib fracture in this species is usually related to mineraldeficiency and complications resulting from unappropriated management. Rib fractures in ruminants are rarely diagnosedand usually present conservative treatment; however, cases with presence of contaminated wounds require extra attention.The objective of this work was to report an atypical case of open fracture of the last rib in a buffalo with ruminal cannula,describing the case from diagnosis to surgical treatment.Case: An adult female water buffalo (Bubalus bubalis) that was well fed and receiving minerals, with implantation ofa ruminal cannula, presented a lesion around the ruminal cannula, with increasing volume, exudation, and myiasis. Thegeneral parameters and behavior of the animal were apparently normal. The animal presented normal appetite and respiration and good physical condition and nutritional state, with pain reaction to the touch in the region of the lesion andtheir adjacencies; it presented no claudication and reluctance to remain in left lateral decubitus, and no discomfort. Theclinical inspection of the cutaneous lesion showed an oblique-type fracture in the body of the last left rib, with exposedbone in the lumbar region and extremity exposed to the ruminal cannula, already presenting necrosis. The region wascleaned, removing larvae (myiasis) for better exposition of the fracture; in the following day...(AU)

O objetivo deste trabalho foi verificar a presença de Brucella abortus e as lesões causadas por esse agente nos anexos fetais e nos fetos de búfalas. Para isso, 20 búfalas em diversos meses de gestação, sorologicamente positivas para brucelose, foram submetidas ao abate sanitário. A idade fetal foi determinada através de exames ultrassonográficos associados à mensuração dos fetos durante a necropsia. Do útero fechado desses animais foram coletadas amostras para histopatologia e qPCR. A partir do segundo mês de gestação foi possível detectar a presença de DNA de B. abortus em líquido amniótico, líquido alantoide e em útero e, a partir do quinto mês, na placenta, coração, baço, rim, pulmão, intestino, fígado e linfonodos dos fetos. Os principais achados anatomopatológicos foram placentite fibrinopurulenta necrótica e endometrite supurativa crônica.(AU)
The objective of this study was to detect Brucella abortus and injuries caused by the bacteria in fetal membranes and fetuses. Twenty buffaloes serologically positive for brucellosis were used and subjected to stamping for collection of material from the closed uterus of several months gestation. Fetal age was determined by ultrasound examination and the size of fetuses was measured at necropsy. The samples were subjected to histopathology and qPCR. From the second month of pregnancy on it was possible to detect the presence of B. abortus DNA in amniotic fluid, allantoic liquid and uterus, and from the fifth month on in placenta, heart, spleen, kidney, lung, intestine, liver and lymph nodes of the fetuses. The main pathological findings were fibrinous suppurative necrotic placentitis, and chronic endometritis.(AU)
