Background: Ascites or pulmonary hypertension syndrome (PHS) is one of the significant problems in the poultry industry. Therefore, various studies have been conducted on its contributing factors. Objectives: This study aimed to investigate the role of vitamin E in reducing the mRNA levels of caspase-1 (CASP1), caspase-2 (CASP2), and caspase-3 (CASP3) genes involved in the apoptosis pathway. Methods: Ninety fast-growing 1-day-old chickens (Ross 308) were randomly assigned to three equal groups, including sham (basal diet), control (basal diet+1.5 mg/kg of triiodothyronine [T3]), and treatment group (basal diet+400 mg/kg of vitamin E+1.5 mg/kg of T3). To induce ascites, 1.5 mg/kg of T3 was added to basal diet from the seventh day to the end of the experiment. On the 21st and 49th days after rearing, 15 chicks from each group were randomly selected. The right ventricle/total ventricle weight ratio (RV/TV) and the expression levels of CASP1, CASP2, and CASP3 genes in the lung and right ventricle of all three groups of broiler chickens were measured and compared. Results: Although there was no significant difference between the three groups in terms of the RV/TV ratio on day 21 post-reared (P≥0.05), a significant decrease was detected in the vitamin E-receiving group compared to the control group with respect to the RV/TV ratio on day 49 post-reared (P<0.05). Also, vitamin E reduced the relative expression of CASP1, CASP2, and CASP3 at 49 days of age in the lung and heart tissues of broiler chickens with ascites (P<0.05). Conclusion: Based on the results of this study, it seems that vitamin E can reduce some apoptosis genes (CASP1, CASP2, and CASP3) associated with pulmonary hypertension in broilers.

Congenital malformations are structural defects that occur in all species during fetal development. Pygomelia is a type of polymelia in which the redundant legs are joined to the pelvis. This abnormality is observed in both human beings and animals. A mixed female (Shih Tzu) puppy with a rigid mass resembling two pelvic hindlimbs was referred to a pet clinic in Mashhad City, Iran. In radiographic assessments, two extra hindlimbs stemmed from malformed pelvic bones and were shorter than normal limbs. Both extra acetabula were detected on the hemipelvis, with two extra coxofemoral joints perpendicular to the regular hip joints in the caudal direction. Also, two vulvas and two anuses were seen, but only one vulva and anus were functional. The additional limbs were amputated by surgery. This case is the first report of a dog with incomplete caudal duplication and successful correction of pygomelia in Iran.

Background: The dromedary spleen plays a crucial role in the immune system and maintaining homeostasis. However, there is limited research on the developmental changes in the spleen during the first few years of a dromedary’s life. Objectives: The objective of this study was to comprehensively investigate the developmental changes in the dromedary spleen during the crucial first three years of life. This aim was achieved through a multi-faceted approach involving macroscopic examination, which entailed measuring the absolute and relative mass of the spleen and morphometric analysis. Additionally, histological and histomorphometric analyses were employed to study the cellular composition of the spleen at different ages. Methods: Five groups of dromedaries were examined in Southeastern Algeria. Their spleens were analyzed using both gross anatomy and histological examination. The cellular composition of their spleens was studied on histological slides of different ages, stained with hematoxylin and eosin. Results: The results showed that the spleen’s size, weight, and volume significantly increased as the animals grew. The splenic mass of the animal of the first group showed an average absolute mass of 251±14.19 g, whereas in the fourth group, they showed an average mass of 318±23.91 g. Also, the length, width, and thickness showed average values of 43.78±1.95 cm, 19.44±1.52 cm, and 1.88±0.16 cm, respectively, at 8 months. However, they showed average values of 49.6±1.86 cm, 24.32±1.69 cm, and 3.18±0.34 cm, respectively, at the age of 3 years. The cellular composition of the spleen changed over time, with a higher percentage of lymphoid tissue at 8 months, more red pulp at 1 year, and a higher percentage of white pulp at 2 years. Finally, the spleen had a mature mixture of red and white pulp and fully developed immune function by 3 years. Conclusion: This study provides new insights into the development and maturation of the dromedary spleen. The findings have important implications for understanding the health and well-being of these animals. The results could potentially contribute to the development of better strategies for the management and care of dromedaries.

Background: In cats, hypertrophic cardiomyopathy (HCM) stands out as a prevailing heart disease. The mutations in the gene that encodes cardiac myosin-binding protein C (MYBPC3) have been detected in the Ragdoll and Maine Coon breeds. Objectives: HCM is believed to be hereditary in other breeds, too. Methods: Blood samples were collected for DNA extraction from 2 unaffected and 7 affected Persian breed cats with HCM. Besides accomplishing conventional polymerase chain reaction, DNA sequencing was performed. The sequence changes were utilized to detect single nucleotide polymorphisms in the MYBPC3 gene and predict amino acid substitutions based on the Acc. No. XM_019812396.1 and comparisons with the literature on identified breed variants and control samples. Results: Although many single nucleotide polymorphisms were found in the affected and unaffected Persian cats, no causative mutation for HCM was observed. Conclusion: In this breed, HCM does not seem to be caused solely by mutations in this cardiac gene. Potential cardiac genes should be investigated to uncover other genetic reasons for this cardiac disease in the Persian cat breed.

Background: Respiratory viral diseases, including the bovine parainfluenza 3 virus, cause significant economic losses in ruminants. There is no available data regarding the epidemiological situation of this virus in Algeria. Objectives: The present study aims to determine the seroprevalence and the associated risk factors of bovine parainfluenza 3 virus (BPI3V) in sheep in two different climatic regions of Algeria. Methods: A total of 108 serum samples were collected from sheep at different ages and tested for antibodies against BPI3V using an indirect enzyme-linked immunosorbent assay (ELISA). A real-time polymerase chain reaction (PCR) test was also performed on nasal swabs to detect the viral genome. Results: At the animal level, out of 108 sera tested, 82 (75.93%, 95% CI, 66.75%, 83.63%) showed antibodies against BPI3V. At the herd level, all 23 herds tested (100%) had at least one animal with BPI3V antibodies. Our results showed no association between the presence of BPI3V antibodies and the region (P=0.72). However, at the herd level, risk factors such as flock size and predisposing factors like climate change, feed deficit, postpartum stress, and dust were identified. At the animal level, a highly significant association was found between BPI3V seroprevalence and the age of the animals (P<0.0001). Notably, the sheep group over 3 years was more susceptible than other age groups. Furthermore, a significant difference in BPI3V seroprevalence based on sex was observed (P<0.003). All collected nasal swabs were negative for BPI3V genome detection using real-time PCR. Conclusion: This study is the first serological survey on BPI3V in Algeria, confirming its presence in sheep from two regions. The high serum prevalence of BPI3V observed in the study population highlights addressing this viral disease to mitigate economic losses in ruminants.

Background: Aflatoxins are harmful mycotoxins that can contaminate animal and human food products. To prevent toxigenic fungi growth and aflatoxin production, researchers have long investigated plant compounds as potential inhibitory agents. Objectives: This study aimed to evaluate the in vitro effect of berberine sulfate and berberine chloride on the growth and aflatoxin production of Aspergillus flavus and Aspergillus parasiticus. Methods: The antifungal activity of berberine salts was determined according to the Clinical and Laboratory Standards Institute (CLSI) document M38-A3. The aflatoxin levels were measured using high-performance liquid chromatography (HPLC) method. Results: The berberine sulfate and berberine chloride showed inhibitory effects against both Aspergillus species, with minimum inhibitory concentration (MIC) ranging from 125 to 500 µg/mL. Berberine sulfate at 2000 μg/mL and berberine chloride at 1000 μg/mL completely inhibited the mycelial growth of A. flavus, while berberine chloride at 1000 μg/mL also completely inhibited the mycelial growth of A. parasiticus. Berberine sulfate at 2000 µg/mL reduced the mycelial growth of A. parasiticus by 96.7%. Conclusion: Berberine salts significantly decreased the total aflatoxin production of Aspergillus species at MIC/2 and MIC/4 concentrations (P˂0.05). The results suggest that berberine salts could be used as potential antifungal and anti-aflatoxigenic agents against toxigenic Aspergillus isolates.

Background: The Rembi sheep breed is renowned for its exceptional meat quality and significant economic profit. Nevertheless, there is a gap in research on the hepatic parameters of this breed in Algeria despite the considerable value of the liver in the Algerian population’s diet. Objectives: The research aimed to determine the impact of physiological factors (age, physiological stage, and body condition score) on biochemical sheep liver parameters. Methods: Sixty clinically healthy female Rembi breed sheep, aged between 3 months and 7 years, raised at the Technical Institute of Livestock (ITELV) Ksar Chellala Farm in Tiaret Province, Algeria, were selected for biochemical analysis and assessing aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), total bilirubin (TBIL), direct bilirubin (DBIL), albumin (ALB), and total protein (TP). Results: The concentrations of AST, ALP, and GGT increased significantly (P≤0.001) in young sheep, while ALT and TP levels decreased (P≤0.05). However, a high level of GGT (P<0.001) was also observed in lactating ewes, and during pregnancy, females have a low level of ALP (P<0.001). Furthermore, the body condition score does not affect any of the measurements. Conclusion: Considering the animal’s age and physiological stage is critical before interpreting the results.

Background: Due to the multifactorial etiology, tumor manifestation in any vertebrate species may become a critical issue. This topic requires more consideration for species in aquatic ecosystems as an enclosed habitat. In addition, knowledge about oncogenesis in the aquaculture industry enhances the quality of products and its earned benefits. Objectives: This study investigated the tumor lesions, their characteristics, and probable causes, in the most commercially important fish in the southern Caspian Sea: Caspian white fish (Rutilus kutum). Methods: To accomplish this goal, after gross pathology of more than 20 cases, histopathological examinations and electron microscopic assays were employed. Results: The findings confirmed squamous cell carcinoma and squamous cell papilloma in the examined cases. Furthermore, the virus-like particles were clearly observed in the transmission electron microscopy results, indicating the probable viral etiology for these neoplastic lesions in Caspian Kutum.

Background: Canine distemper (CD) is the dogs’ most contagious and lethal viral disease. Despite the widespread use of vaccines to control CD, the prevalence of the CD virus (CDV) has increased at an alarming rate in recent years. Objectives: To identify the genotypes responsible for the neurological and non-neurological clinical forms of CD and to investigate the presence of the virus in the neurological and non-neurological forms of the disease. Methods: In this descriptive-analytical study, the samples were collected from 70 CD suspected unvaccinated dogs with clinical signs of distemper. All cases were tested with rapid tests and separated into 3 groups based on clinical signs and symptoms. Cerebral spinal fluid (CSF), respiratory secretion, and fecal samples of allall 70 cases were examined for reverse transcription polymerase chain reaction (RT-PCR). After sequencing the hemagglutinin gene (H gene), phylogenetic analysis of the gene isolated from CDVs was carried out using MEGA software, version 7. Results: The RT-PCR results showed that the respiratory secretion sample in the non-neurological CDV group (85%) and the neurological CDV group (80%) had the highest level of virus contamination. However, in the non-neurological CDV group, the CSF sample (40%) had a high level of infection. In neurotic groups, cases older than 12 months showed the highest percentage of distemper contamination, and in the non-neurologic CDV group, those between 3 and 6 months were more involved. Sequencing and phylogenetic analysis of the H gene revealed the CDV as a member of the endemic Arctic-like genetic lineage. Conclusion: The genotypic examination of the hemagglutinin gene of the distemper virus reveals that the recent isolates of neurologic and non-neurologic clinical forms of CDV in Iran are similar. In positive rapid test cases, the PCR test of respiratory secretions for virus detection ranks with the highest sensitivity. In neurologic cases with negative rapid test results, PCR of CSF had the highest sensitivity, so it may serve as a diagnostic criterion.
背景：犬瘟热（CD）是犬最具传染性和致命性的病毒性疾病。尽管已广泛使用疫苗来控制犬瘟热，但近年来犬瘟热病毒（CDV）的流行率仍以惊人的速度增长。研究目的确定导致 CD 的神经性和非神经性临床形式的基因型，并调查该病毒在神经性和非神经性疾病中的存在情况。研究方法在这项描述性-分析性研究中，从 70 只疑似 CD 且未接种疫苗、有犬瘟热临床症状的狗身上采集了样本。所有病例均经过快速检测，并根据临床症状和体征分为三组。对所有 70 个病例的脑脊液（CSF）、呼吸道分泌物和粪便样本进行了反转录聚合酶链反应（RT-PCR）检测。在对血凝素基因（H 基因）进行测序后，使用 MEGA 软件 7 版对从 CDV 病毒中分离出的该基因进行了系统进化分析。结果显示RT-PCR 结果显示，非神经系统 CDV 组（85%）和神经系统 CDV 组（80%）呼吸道分泌物样本的病毒污染程度最高。然而，在非神经系统 CDV 组中，脑脊液样本（40%）的感染率较高。在神经系统组中，12 个月以上的病例感染犬瘟热的比例最高，而在非神经系统 CDV 组中，3 至 6 个月的病例感染率较高。对 H 基因的测序和系统发育分析表明，CDV 属于流行的北极类基因系。结论通过对犬瘟热病毒血凝素基因的基因型检测发现，伊朗最近分离出的神经系统临床型和非神经系统临床型 CDV 相似。在快速检测呈阳性的病例中，呼吸道分泌物的 PCR 病毒检测灵敏度最高。在快速检测结果为阴性的神经系统病例中，CSF 的 PCR 检测灵敏度最高，因此可作为诊断标准。

Background: Fertility in male animals is an important issue in veterinary medicine. Exposure to severe crowding and fattening may affect the fertility of these animals. Objectives: This study compares the effect of oxidative stress caused by overcrowding or obesity on testicular tissue in male albino mice. Methods: A total of 30 male mice were divided into 3 groups. The first was a control group. The second group was subjected to crowding by cramming 20 mice in a small cage. The third group was fattened by eating a high-fat diet. Morphometric cells and histological measurements of the seminiferous tubule diameter, epithelium thickness, and Sertoli and Leydig cell counts were taken. Results: The crowding group testes showed the presence of necrosis and degeneration of spermatocytes, Sertoli, and Leydig cells. The obese group’s spermatocytes, Sertoli, and Leydig cells had shown severe necrosis, degeneration, and giant cell invasion. Histomorphometric measurements of seminiferous tubule diameter, epithelium-thickness, and Sertoli and Leydig cell counts revealed a considerable reduction in the obese group compared to the other groups. Furthermore, in the crowding and fattening groups, measurements of oxidative stress indicators revealed a decrease in glutathione value in the obese group compared to the control, whereas malondialdehyde rose in the overcrowded and obese groups compared to the control. The results of the immunohistochemical expressions for tumor necrosis factor-α (TNF-α) in the testes of mice revealed weak TNF-α positive expression in the control group, moderate expression in the crowding group, and strong expression in the obesity group. Conclusion: The study suggests that both obesity and crowding can impair testicular function, with obesity having the most significant impact. More research into the mechanisms underlying these effects, as well as potential interventions to improve testicular function in obese or overcrowded animals, is required.
