This study was aimed to determine the effect of epididymis extract (EE) on the testosterone and dihydrotestosterone (DHT) level of local male goat. An experimental study was performed using a completely randomized design (CRD) pattern of one-way analysis of variance (ANOVA). 15 local male goats aged 1.5 years with body weight 14-16 kg were used in this study. The K0 group as a control group, injected with only 1 ml physiological saline, while each KP1, KP2, KP3, and KP4 groups treated with multilevel EE dose, ie 1, 2, 3, and 4 ml / goat for 13 consecutive days. At the end of treatment (day 14th), testes, epididymis (caput, corpus, and cauda) and ductus deferens samples were taken through the close-castration method for examining the testosterone and DHT concentration by using enzyme-linked immunosorbent assay (ELISA) technique. Data gathered were later analyzed using ANOVA followed by Tukey’s HSD in SPSS 16.0 for Windows. The result showed that the average concentration of testosterone on K0, KP1, KP2, KP3, and KP 4 in testis respectively were 10.00±2.64 ng/ml; 7.66±2.51 ng/ml; 10.00±6.55 ng/ml; 0.66±0.57 ng/ml; 11.66±7.37 ng/ml; caput epididymis; 5.00±1.73 ng/ml; 2.33±1.52 ng/ml; 5.00±2.64 ng/ml; 1.33±0.57 ng/ml; 5.66±1.15 ng/ml; corpus epididymis; 1.33±0.57 ng/ml; 0.66±0.57 ng/ml; 4.00±2.64 ng/ml; 0.66±0.57 ng/ml; 4.33±2.30 ng/ml; cauda epididymis: 1.00±0.00 ng/ml; 0.66±0.57 ng/ml; 1.66±0.57 ng/ml; 1.00 ± 0.00 ng/ml; 2.00±1.73 ng/ml; ductus deferens: 3.66±2.51 ng/ml; 0.66±0.57 ng/ml; 3.00±1.00 ng/ml; 1.00±0.00 ng/ml and 3.66±1.15 ng/ml. While the average concentration of DHT on K0, KP1, KP2, KP3, and KP 4 in testis respectively; 10.00±2.64 ng/ml; 7.66±2.51 ng/ml; 10.00±6.55 ng/ml; 0.66±0.57 ng/ml; 11.66±7.37 ng/ml; caput epididymis; 5.00±1.73 ng/ml; 2.33±1.52 ng/ml; 5.00±2.64 ng/ml; 1.33±0.57 ng/ml; 5.66±1.15 ng/ml; corpus epididymis; 1.33±0.57 ng/ml; 0.66±0.57 ng/ml; 4.00±2.64 ng/ml; 0.66±0.57 ng/ml; 4.33±2.30 ng/ml; cauda epididymis: 1.00±0.00 ng/ml; 0.66±0.57 ng/ml; 1.66±0.57 ng/ml; 1.00 ± 0.00 ng/ml; 2.00±1.73 ng/ml; ductus deferens: 3.66±2.51 ng/ml; 0.66±0.57 ng/ml; 3.00±1.00 ng/ml; 1.00±0.00 ng/ml and 3.66±1.15 ng/ml. Statistical analysis showed that the administration of EE only increased testosterone concentration in testes had significant effect (P 0.05). From this study, it can be concluded that the EE has the potential to improve spermatogenesis and sperm quality through increasing the testosterone concentration in the local male goats.

Medical records from 860 pigeons and doves of 24 species housed in Bristol Zoo Gardens and Wild Place Project, United Kingdom, from 2000 to 2017 were reviewed to determine the causes of morbidity in captive columbiformes. Accounted 205 cases (51.25%), infectious disease was found as the primary cause of morbidity, followed by 133 cases of trauma (33.25%), 51 (8.9%) cases of non-infectious disease, and 8 (2%) cases of husbandry-related problem. The main cause of infectious disease was parasite infection with 35% over 31% of bacterial, 26% of undetermined etiology and 9% of fungal infection. More specific, nematodiasis was the most frequent parasitic disease found, presented in 49 (69%) cases and followed by 10 (14%) trichomoniasis of all parasite infection. Meanwhile, chlamydiosis was a leading cause of bacterial infection with 22 (35%) cases recorded of over 63 bacterial infections. These results highlight the importance of preventative medicine implementation in captivity which aims to detect the disease earlier hence reducing the worsening physical condition and minimising the risk of both zoonotic and non-zoonotic disease transmissions. In addition, these findings contribute to the limited information available regarding the captive columbiformes morbidity

This report describes a case of mammary gland tumor in a 1-year-old female cat using a mastectomy approach. The tumor was located on dexter side of mammae. Blood analysis showed good condition of the patient and ready for surgery. Mastectomy was conducted to remove the mass, and the tumor size was measured 7x5x4 cm with solid appearance. The cat was given antibiotics to prevent infection, and the wound dried in five days.

Feline chronic gingivostomatitis (FCGS) is a challenge for the veterinary practitioner since its etiology and treatments are still undefined. The present paper investigated the role of the feline immunodeficiency virus (FIV) in the severity of the FCGS. Oral mucosal biopsies obtained from 19 cats with FCGS were divided into two groups according to their FIV serology status. Later, the clinical lesion score was correlated with the histopathological grade of FCGS lesions and the degree of immunostaining in both groups. Most of the animals had significant histological changes; however, no correlation with FIV immunostaining intensity was observed. It was concluded that the presence of FIV infection or the animal’s seropositivity status does not seem to interfere with the severity of clinical signs nor the degree of histopathological changes when compared to the seronegative group.

In general, European and North American countries, as well as Australia and New Zealand, have already eradicated or reached good levels of control of brucellosis and tuberculosis in cattle. In the rest of the world, however, the epidemiological situation of these two diseases is frequently poorly understood. In this review article, quantified data on these diseases in the South American countries are presented. Initially, the aspects that led the continent to host 25% of the world cattle population are presented, in addition to the aspects that placed the continent at a prominent position in the international meat market. Subsequently the continent was divided into three country groups, considering the size of the cattle population and how well the epidemiological situation of brucellosis and tuberculosis in cattle is quantified. It is argued that countries that do not generate high-quality quantitative epidemiological data on these diseases have serious limitations in outlining and managing control or eradication strategies. Thus, for successful outcomes, at least methodologies to estimate the prevalence of infected herds should be employed.

The present study evaluated the dietary supplementation with essential oil of Lippia alba on the hemato-immunological parameters of Nile tilapia (Oreochromis niloticus) submitted to acute inflammation induced by carrageenin injection in the swim bladder. For a period of 45 days, 96 fish were divided in four treatments in triplicate, as follows: fish fed supplemented diet with essential oil of L. alba (4 mL kg-1 dry ration) injected with carrageenin; fish fed supplemented diet with cereal alcohol injected with carrageenin; fish fed unsupplemented diet with essential oil injected with carrageenin; fish fed unsupplemented diet and noninjected. Cortisol levels, erythrogram, leukogram and the inflammatory infiltrate were analyzed 6 h after inflammatory stimulus. Carrageenin-injected fish showed acute inflammatory reaction in the swim bladder characterized by higher infiltrate of neutrophils and monocytes. The circulating neutrophils number was significantly higher in fish fed L. alba when compared to other treatments. No difference in cortisol levels was found. For dose, time and administration form tested, supplementation with essential oil of L. alba did not present anti-inflammatory activity. On the other hand, influence of dietary supplementation was observed on the neutrophils number after induced aerocystitis highlighting its immunomodulatory characteristic.

vulnerability. The fact that these people share the environment with animals promotes the establishment of zoonotic parasitic infections, as well as the resultant parasitic cycles. Thus, parasites present in the environment must be identified, so that control measures can be recommended. In this context, this study’s objective was to evaluate environmental contamination by parasitic forms in a socially vulnerable community in southern Rio Grande do Sul. A total of 100 soil samples collected from the community were processed by a sodium dichromate centrifuge-flotation technique and analyzed by a compound microscope (40X objective) for the identification of parasite eggs, oocysts and cysts. All points were positive for two or more parasites, with the identification of 33.59% non-identified coccidian oocysts, Strongylida (25.4%), Ascaridida (21.31%), Trichuris spp. (8.19%), Toxocara spp. (3.27%), Amoebas (4.08%), Dioctophyma renale (2.45%), and Giardia spp. (1.63%). The presence of parasitic forms in all points analyzed surpasses other studies of environmental contamination carried out in the southern region of Brazil. In addition, the identification of several parasitic forms with zoonotic potential is concerning, since it shows the possibility of parasitic transmission to humans and other animals. In view of the results, the conclusion is that the environment analyzed is contaminated by parasitic forms, constituting a serious public health problem. Therefore, implementing educational and preventive measures in the community to control parasites is of crucial importance.

Protocols for cooling or freezing goat semen usually recommend centrifugation for seminal plasma removal. However, little is known about the effect of this process on goat sperm viability and functionality. The present study evaluated the effects of centrifugation force on the plasma membrane, acrosomes, and DNA integrity of goat semen. Four ejaculates from each of the four different Anglo Nubian male goats were used. Semen samples were obtained using artificial vagina, and immediately after collection, ejaculates were diluted using Ringer’s sodium lactate solution and split into three groups: Control (CG, without centrifugation), G1 (centrifugation 600 x g/10 min), G2 (centrifugation 1200 x g/10 min). After centrifugation, seminal plasma was removed, the sperm pellets were resuspended using Tris-egg yolk extender (80 x 106 spermatozoa/mL) and the sperm morphology was analyzed. Samples were cooled at 5°C for 5, 24, 36, and 48 h and then sperm plasma membrane and acrosome integrity (PMAI, %) and sperm DNA fragmentation index (SDF, %) were evaluated at each time-point, using a flow cytometer. Additionally, sperm movement was determined using computer semen analysis (CASA) after 5, 24, and 48 h of refrigeration period. The semen centrifugation did not induce additional sperm morphology defect or reduction in sperm kinetics in the experimental groups. Differences were not observed (p > 0.05) in PMAI and SDF among different groups, in any of each timepoint of the cooling process. In conclusion, centrifugation, even at high speeds, did not affect goat sperm integrity and functionality when submitted to refrigeration process.

It is well known that posterior capsule opacification (PCO), one of the most common late postoperative complications of cataract surgery, is mainly caused by proliferation and differentiation of remaining lens epithelial cells (LECs) on the posterior lens capsule. Many authors suggest that alterations induced by the pathophysiology of cataracts, its metabolism and the use of 0.1% trypan blue (TB) must cause some degree of cellular damage on these cells, wicht would help to prevent and/or reduce the incidence of PCO after cataract surgery in humans. Therefore, the aim of this study was to evaluate the expression of cell death markers on LECs of older dogs with diabetic and hypermature cataracts, after capsulorhexis, both using 0.1% TB. Twenty samples collected from 13 dogs of different breeds, with ages varying from 8 to 12 years-old, with diabetic and hypermature cataracts, which had been subjected to phacoemulsification surgery (Phaco) using 0.1% TB for staining were studied. Animals were classified as dogs with diabetic (DC) and hypermature cataracts (HC), and expression of molecular markers for apoptosis and autophagy (caspase-3 and beclin-1) on LECs were obtained by immunofluorescence technique. The expression of caspase-3 and beclin-1 was observed in every studied sample and did not differ between groups. In conclusion, our findings suggest that apoptosis and autophagy processes occur to LECs in older dogs presenting diabetic and hypermature cataracts after Phaco utilizing 0.1% TB. Our results may be helpful to future studies of PCO in post-phacoemulsification surgery patients.
