African swine fever (ASF) is a contagious haemorrhagic disease associated with causing heavy economic losses to the swine industry in many African countries. In 2017, Zambia experienced ASF outbreaks in Mbala District (Northern province) and for the first time in Isoka and Chinsali districts (Muchinga province). Meanwhile, another outbreak was observed in Chipata District (Eastern province). Genetic analysis of part of the B646L gene, E183L gene, CP204L gene and the central variable region of the B602L gene of ASF virus (ASFV) associated with the outbreaks in Mbala and Chipata districts was conducted. The results revealed that the ASFV detected in Mbala District was highly similar to that of the Georgia 2007/1 isolate across all the genome regions analysed. In contrast, while showing close relationship with the Georgia 2007/1 virus in the B646L gene, the ASFV detected in Chipata District showed remarkable genetic variation in the rest of the genes analysed. These results suggest that the Georgia 2007/1-like virus could be more diverse than what was previously thought, underscoring the need of continued surveillance and monitoring of ASFVs within the south-eastern African region to better understand their epidemiology and the relationships between outbreaks and their possible origin.

Shiga toxin-producing Escherichia coli (STEC) O157 and non-O157 are food-borne pathogens and contaminants of foods of animal origin. This study was conducted to investigate the presence of virulence and integrase genes in STEC isolates from diarrhoeic calves in Fars Province, Iran. Five hundred and forty diarrheic neonatal calves were randomly selected for sampling. Rectal swabs were collected and cultured for isolation and identification of E. coli following standard methods. The isolates were analysed for the presence of class 1 integrons and bacterial virulence factors using polymerase chain reaction (PCR). Antimicrobial susceptibility testing was performed using the Kirby–Bauer disc diffusion method. Out of 540 diarrhoeic faecal samples, 312 (57.7%) harboured E. coli and 71 (22.7%) of them were identified as STEC: 41(69.5%) carried the stx2 gene, 21 (35.6%) carried the stx1 gene and 3 (5%) carried both. Twenty-six (44%) of the isolates showed the eaegene. Among the STEC isolates examined for susceptibility to eight antimicrobial agents, erythromycin and penicillin (96.8%) resistance were most commonly observed, followed by resistances to ampicillin (71.8%), tetracycline (62.5%) and trimethoprim/sulfamethoxazole (39%). Integrons were detected by PCR in 36% of the STEC tested isolates, 57 (89%) of which showed resistance to at least three antimicrobial agents. Our findings should raise awareness about antibiotic resistance in diarrhoeic calves in Fars Province, Iran. Class 1 integrons facilitate the emergence and dissemination of multidrug-resistance (MDR) among STEC strains recovered from food animals.

Artemeva E.A
The objective of the present work was to investigate the anatomical and histological structures of haemolymph nodes in the adult water deer (Hydropotes inermis argyropus). Methodology: the morphology of haemolymph nodes from 5 adult water deer was studied by gross inspection and by histological methods. Results: the haemolymph nodes were determined for the first time in water deer (Hydropotes inermis argyropus). The nodes located in the neck on the trachea, thoracic and abdominal cavities in water deer. Dark red in color and oval- or round shaped haemolymph nodes in water deer were observed particularly along the abdominal aorta and caudal vena cava; as well as on the trachea along the jugular vein, on the internal carotid artery and internal jugular vein and on the aortic arch. These nodes had a hilus with hilar vessels, which entered the haemolymph nodes through the trabeculae as trabecular artery. The parenchyma was organized in the form of cortex and medulla. Lymphoid rim was located between subcapsular sinus and cortex. The cortex was composed of a many secondary lymphoid follicles and diffuses interfollicular lymphoid tissue, and medulla contained medullary cords and medullary sinuses. A reticular meshwork extended throughout the haemolymph nodes formed the structure backbone. The interstices of the reticular meshwork were filled with free blood cells, many macrophages, lymphocytes, and plasma cells. Conclusion: the dark red haemolymph nodes of water deer examined were seen along the course of large blood vessels in the neck on the trachea, thoracic and abdominal cavities. This is first study has demonstrated the presence of haemolymph nodes in water deer (Hydropotes inermis argyropus) and provided essential information on their anatomical and histological structures. The data obtained in the present study may be used for further research in this field

The oral use of pregabalin was evaluated in this study to reveal its effects on some hematological and biochemical parameters of laboratory mice. The animals of this study were divided into three groups (twelve mice each). The control group was fed on a standard ration. The first treated group (Pregabalin 1) were dosed orally with one ml of distilled water containing Pregabalin (20 mg/ml/mice/ day). The second treated group (Pregabalin 2) were dosed orally with one ml of distilled water containing pregabalin (40mg/ml/mice/ day). The experiment continued for two successive months. The results showed that the use of pregabalin caused a significant declination in R.B.C., HGB, HCT, W.B.C., M.C.V., MCH, and MCHC of both treated groups compared them with control group and the declination was more significant in (pregabalin 2) group compared with (pregabalin 1) group. The RDWCV, RDW-SD, and PLT increased significantly in both treated groups as compared with those of the control group. However, PCT, PDW and MPV were not affected by the use of pregabalin except the MPV of (Pregabalin 2) group was significantly less than that of (Pregabalin 1) but without a significant difference compared with that of control. The Fe++, and GLU decreased significantly in both treated groups compared with the control and they declined more significantly in (Pregabalin 2) compared with (Pregabalin 1). Both the TP and Ca++ did not affected by the use of pregabalin compared with the control group (P≤0.05)

Brucellosis an intracellular pathogen capable of infecting animals and humans. The aim of this study was to identify Brucella spp in apparently healthy cow and goat raw milk samples by a polymerase chain reaction (PCR)-based method. A total of 75 cow milk samples(55 direct and 20 indirect) and 50 goat milk samples were examined by PCR. To establish a PCR protocol for diagnosis of brucellosis, DNA was extracted from the milk samples by using a commercial kit. PCR amplification was done for detection of Brucella DNA using BCSP31 target gene and IS711 locus. The PCR assay showed that an amplicon of 223 bp was obtained in 28% (21/75) and 8% (4/50) samples of cow and goat tested milk using primers (B4/B5) derived from aBCSP31gene encoding the 31-kDa Brucella abortus antigen. In another PCR, an amplicon of 498 bp was obtained in 100% (21/21) of the brucella genus BCSP31-PCR positive cow milk samples using Brucella abortus-specific primers derived from a locus adjacent to the 3’-end of IS711, and also an amplicon of 731 bp was produced in 100% (8/8) of the BCSP31-PCR positive goat milk samples using Brucella melitensis-specific primers.PCR positive results for brucella genus and brucella abortus species were observed in all (100%) cow,s milk samples(n=11) with clinical history of abortion.As a single PCR product, no B. abortus was detected in goat milk samples alsoB. Melitensis was not detected in cow milk samples

Muna H. AL-Saeed | Ikbal A.H.AL-Rufaei
This study was designed to evaluate the ameliorative effect of selenium on reproductive efficiency of adult male rats with thyroid disturbance. Hypothyroidism state was induced by administration of antithyroid drug propylthiouracil (PTU) (50mg/kg.B.W.) and hyperthyroid state was induced by administration of LThyroxine(L-T4) (50μg/kg.B.W.). Selenium (Se) treated rat group was given sodium selenite (10 μg/kg.B.W.). Sixty adult male rats of (180-200 gm) body weight were used in this study and divided into six main groups. Control group, PTU treated group, L-T4 treated group, Se treated group, Se+PTU treated group and Se+L-T4 treated group. All these groups were drenched orally by gavage tube for two months. The obtained results revealed that hypothyroidism is accompanied by significant (P<0.05) decrease in serum T3, T4 concentrations compared with control and another treated groups and significant increase (P<0.05) in hyperthyroidism group a compared with control. On the other hand, TSH concentration showed a significant (P<0.05) increase in hypothyroidism group and significant decrease (P<0.05) in hyperthyroidism group as compared with control and another treated group. A significant decrease in serum concentrations of FSH, LH and testosterone have been shown in serum of hyper- and hypothyroidism groups. Semen analysis showed a significant decrease (P≤0.05) of epididymal sperm concentration, sperm motility, and viability and a significant increase (P≤0.05) of sperm22 abnormalities were recorded in PTU and L-T4 groups compared with control and another treated group. While a significant increase (P≤ 0.05) of epididymal sperm concentration, sperm motility and viability and a significant decrease (P≤ 0.05) of sperm abnormalities were recorded in Se alone, Se+PTU group and Se+L-T4 group. Also, histological examination on the testis showed that rats treated with Se, Se+PTU and Se+L-T4 had normal architecture of seminiferous tubules with different stage of spermatogenesis. Whereas, rats treated with L-T4 alone or with PTU exhibited vacuolation of spermatogonia and suppression of spermatogenesis.
