The complete bleeding in slaughtering animals is closely related to the halalness of the meat. This study aims to describe the completeness of blood drains in discarded laying hens carcasses sold at traditional markets in Banda Aceh City. The research samples were nine chicken carcasses bought from three traditional markets, i.e., Peunayong, Ule Kareng, and Seutui (three samples from each market). The study used a cross-sectional method to test the perfect carcass bleeding with the Malachite Green (MG) test in the form of seeing changes in the color of the solution. The results showed that all samples changed color from green to dark blue. A perfectly slaughtered chicken will not find hemoglobin in the chicken carcass, causing O₂ to oxidize malachite green to a dark blue, indicating that the slaughtering and bleeding occurred completely. In conclusion, the carcasses of discarded laying hens sold in the traditional markets of Peunayong, Ule Kareng, and Seutui are halal.

This study aims to determine the histomorphometry of the small intestine of turkeys (Meleagris gallopavo) at different age levels. This study used a completely randomized design. This study used 18 male turkeys, divided into 3 groups of ages 8, 16, and 24 weeks, each group comprising 6 turkeys. The necropsied turkey's small intestine was taken into histological preparations and stained with haematoxylin-eosin (HE). The results showed that the histological picture of the small intestine layer of turkeys at different age levels consisted of four layers: tunica mucosa, tunica submucosa, tunica muscular, and tunica serosa. Histomorphometrically, there was an increase in the thickness of all layers of the small intestine from 8 and 16 weeks of age (P0.05), and the height of the intestinal villi increased in all parts of the small intestine at 8, 16 and 24 weeks of age (P0.05 ). In conclusion, with histomorphometric measurements, it can be seen that there are differences in the three age groups.

Blood is a good growth medium for bacteria by preventing the accumulation of toxic oxygen (peroxide and superoxide) and increasing the growth ability of these bacteria. The purpose of this study was to evaluate the ability of lysed sheep blood and lysed cow blood as a substitute for lysed horse blood on Campylobacter growth media, as well as evaluate the growth of Campylobacter from chicken meat samples on culture media supplemented with lysed sheep blood and lysed cow blood compared to the media cultures using lysed horse blood supplements. The concentration of lysed sheep blood, lysed cow blood, and lysed horse blood used was 5% each. The chicken meat samples used in this study were 30 samples. Based on the results, 14 samples of C. jejuni bacteria showed the ability to grow up to 107 and 16 samples up to 106. In the media added with lysed cow blood supplement only one sample was able to grow up to 106, 17 samples grew up to 105, and 12 samples grew up to 104. These results statistically used the one way analysis of variance (ANOVA) test indicating a significant difference significant (P0.05). Further tests using post hoc least significance different (LSD) showed a comparison of the average growth in lysed horse blood, lysed sheep blood, and lysed cow blood significantly different (P 0.05), while the average value of each treatment was the addition of lysed horse blood supplements, lysed sheep blood, and cow blood consecutive lysis was 8.551 ± 0.340, 7.117 ± 0.544, and 5.265 ± 0.548. The addition of lysed sheep blood and lysed cow blood to bolton broth media in this study can be used for C. jejuni isolation. However, the blood of lysed sheep had a higher effectiveness in the ability to grow C. jejuni, which was close to the ability to grow with the addition of lysed horse blood as a control, compared to the addition of lysed cow blood.

The gut microbiota has a major contribution in human physiology and influences disease pathogenesis, including in tuberculosis (TB) lung infection. Gut-lung axis has demonstrated the interplay of these two organs, mediated by metabolites produced by the gut microbes or derived from host molecules transformation. Tryptophan (Trp) is one of the essential aromatic amino acids catabolized as kynurenine, serotonin (5-hydroxytryptamine), and indole derivatives, including indole propionic acid (IPA), via 3 pathways. The latter was microbiota-derived Trp catabolism, which has known to have an immunomodulatory role, as ligands for Aryl hydrocarbon Receptor (AhR). Intriguingly, Mycobacterium tuberculosis required Trp as a nitrogen source, especially in CD4+ T cells-generated stress, to survive in the phagosome of macrophage and to cause disease. Recently, IPA is identified as a new anti-mycobacterial compound, which is specific and has broad spectrum of anti-mycobacterial activity. The structural similarity of this gut microbiota-derived metabolite and Trp allows IPA to inhibit the TrpE anthranilate synthase in Trp biosynthesis pathway in Mtb. In this review, we summarize findings from recent work by focusing on the role of Trp metabolites in host cells in TB infection.  A better understanding of this chemical signal could potentially serve as a novel strategy for managing this chronic inflammatory disease.

Fourteen female dogs diagnosed with pyometra were studied at three separate times: at diagnosis (T0) and 24 h (T1) and 10-15 days (T2) after ovariohysterectomy (OH). The means of the markers, symmetric dimethylarginine (SDMA) (17.71 to 26.54 μg/dL) and the urinary gamma-glutamyl transferase to creatinine ratio (uGGT/uCr) (1.06 to 2.62 U/mg), varied, showing an increase with time. Further, the elevation of gamma-glutamyl transferase (uGGT) (56.61 to 128.12 U/L) and the urinary protein to creatinine ratio (RPC) (0.26 to 1.24) was evident at T0 and T1. A reduction in the means of RPC, uGGT, and uGGT/uCr was observed 10-15 days after OH. Despite the elevation of these markers, the concentration of creatinine (1.11 to 1.40 mg/dL), urea (40.07 to 67.16 mg/dL), and urinary specific gravity (1.027 to 1.028) only presented slight variation. In canine pyometra, complications secondary to acute renal injury may be present that may be mild and transient in most treated animals. As elevation in SDMA and RPC preceded changes in creatinine levels for the evaluation of glomerular filtration, tubular markers could assist in the early identification of renal damage in canine pyometra.

The center of rotation of angulation (CORA)-based leveling osteotomy (CBLO) technique was developed for cranial cruciate ligament (CrCL) rupture treatment, aiming to modify the mechanical-anatomical angle (AMA), which is described as a predictive risk factor for the disease and is recommended to be taken into consideration when one is choosing a surgical procedure for tibial plateau slope alteration. Identifying a tibial distal anatomical axis (DAA) is essential in CBLO surgical planning and measuring AMA amplitude. The aim of this study was: to evaluate two methods of cranial rotation of the proximal fragment using four different tibial distal anatomical axes for digital planning on the CBLO technique, comparing its effectiveness in achieving the desired tibial plateau angle (TPAd) and closing the AMA angle. Tibial measurements were made with the vPOP pro software using 30 mediolateral radiographs of canine stifles. The DAA described by four authors was used based on the amount of Rotation completed (Rc) for each. The rotation methods evaluated were: 1) commercial CBLO table (RT) and 2) overlapping the tip of the intercondylar eminence with the corresponding DAA line (RE). The TPAd to be obtained was fixed at 10°, and the final AMA to be achieved at 0°. The mean values and standard deviations of the final TPA and final AMA with the rotation method were TPA(RT)f(%TPAd), TPA(RE)f(%TPAd), AMA(RT)f(%AMAzero), AMA(RE)f(%AMAzero). The results of each author were Hulse 10.0 ± 0.3(46.6%), 9.9 ± 0.1(60%), 0.3 ± 0.3(33.3%), 0.3 ± 0.3(13.3%), Osmond 10.1 ± 0.2(75%), 10,1 ± 0.2(83.3%), 0.4 ± 0.4(33.3%), 0.4 ± 0.3(8,3%), Miles 10.0 ± 0.1(66.6%), 10.0 ± 0.1(75%), 0.2 ± 0.1(16.6%), 0.2 ± 0.1(8.3%), Tudury 9.6 ± 0.6(31.2%), 9.5 ± 0.2(31.2%), 1.0 ± 0.7(18.7%), 1.0 ± 0.6(12.5%), respectively. The initially described RT obtained a higher percentage of AMA at zero degrees. Therefore, the RE method is discarded for use as an alternative to CBLO planning.

Both pregnancy and obesity can influence significant changes in the immune system. On this basis, the present study proposes to evaluate the humoral immune response of overweight pregnant mares in response to a commercial vaccine. Thirty pregnant Crioulo mares were separated according to body condition score (BCS) into overweight (BCS≥7/9) or lean-control (BCS= 5-6/9). In each group, the animals were subdivided into vaccinated and controls. The mares were vaccinated against EHV-1 in two doses spaced 21 days apart and had their blood collected monthly, for five months, for antibody evaluation. Both vaccinated groups had an increase in specific neutralizing antibodies after the vaccine. However, after the second dose, there was no increase in antibodies in any of the groups. Vaccinated overweight and lean-control mares did not differ at any time point. Therefore, this study demonstrated that obesity does not influence the humoral immune response in pregnant Crioulo mares.

Gallbladder mucocele is characterized by hyperplasia of the gallbladder epithelium, increased mucus production, accumulation, and densification of the bile content, which can lead to biliary obstruction, necrosis, and rupture of the gallbladder wall. Its finding may be accidental or related to symptoms. A retrospective study (2016-2019) was carried out based on abdominal ultrasound examinations in dogs, correlating aspects of the gallbladder and biliary system in the mucocele with existing comorbidities. Thirty dogs diagnosed with biliary mucocele were evaluated, of which 46.66% had the disease at an early stage, and 53.33% showed a more advanced stage. Of these, 66.66% were related to endocrinopathies and hyperadrenocorticism. Signs of extrahepatic bile duct obstruction and biliary peritonitis were observed in two animals. Due to their potential risk of complications, follow-up ultrasound assessments are indicated in cases that opt for clinical treatment, not excluding the need for surgical intervention.
