Vaccination is an important disease prevention and control measure; however, vaccine adoption by livestock farmers in Tanzania is still low. This cross-sectional study examined the challenges to vaccine use faced by livestock owners and animal health professionals (AHPs) in Tanzania. A questionnaire was administered to 216 households that kept small ruminants and poultry and 19 AHPs’ data were collected electronically via the survey platform Qualtrics, and descriptive statistics were performed. Households with poultry reported vaccinating mostly against Newcastle disease (91.7%), fowl pox (48.1%) and Gumboro disease (37.0%), whilst households with small ruminants reported contagious caprine pleuropneumonia (62.2%), sheep and goat pox (17.1%), foot-and-mouth disease (7.3%) and peste des petits ruminants (7.3%). The households’ decision to vaccinate was mostly influenced by knowledge of diseases (82.4%), disease history on the farm (69.4%) and vaccine price (63.4%). Most households (54.6%) experienced challenges when purchasing vaccines, including high vaccine cost (78.0%), long distance from vaccine source (61.0%) and vaccine unavailability (21.2%). The findings suggest that improving the knowledge of livestock owners regarding the priority diseases and the benefits of vaccination, establishing more vaccine suppliers, improving vaccine distribution and access and training AHPs and households on appropriate vaccine storage and handling are necessary to improve vaccine adoption and ensure vaccine quality and effectiveness.

Arwa AL-Saeed | Manar Mohammed Hizam Hizam
Newcastle disease is a highly contagious and devastating viral disease ofpoultry that distributed worldwide causing large economic losses in the poultryindustry. Although vaccines are being used to control the disease, there is no effectiveantiviral drug used for the treatment of infections. The aim of this study is to testgarlic oil for its antiviral activity against Newcastle disease virus. Garlic oil wasincubated with the virus (LaSota strain) for 1 hr and 24 hrs and its antiviral effect wasdetermined by performing hemagglutination and RT-PCR tests to detect viral surfaceproteins and viral genome, respectively. In addition, the toxicity of garlic oil wasdetermined on the living organism by injecting it into chicken embryos with orwithout the virus. The results showed that this product played a role in the reductionof virus effectiveness through the destroying of viral surface receptors as well as thereduction of gene amplification as compared with the control group that included thetreatment of the virus with a saline solution (phosphate buffer saline), which gaveopposite results. In addition, there was no antiviral toxicity on the living organismsince the injected embryos with the oil alone or the oil with virus were healthy andclosely resemble those that have not been injected with anything. In comparison, theembryos that were injected with the virus only showed clear pathological signs thatdid not appear in the other groups containing the oil. These results suggest that garlic oil would be a good potential antiviral and probably will have a role to eliminate thedisease.

The present study aims to isolate and identify Escherichia coli from fecal samples of farmanimals and human, also, it aims to molecular detection of shigatoxin and intimin genes inisolates. A total of (264) fecal samples and swabs were collected from different parts of Basrahin the period extending from September 2018 to January 2019. These samples were composed of(85) samples from cows, (94) samples from humanand (85) samples from sheep. Differenttechniques were used in this study to detect the presence of E. coli; these techniques includedconventional microbiological assays and molecular techniques (amplification of uidA gene byusing polymerase chain reaction).The results of these techniques indicated 50 (18.9%) were E. coli from the tested samples.These isolates were subjected to PCR to detect Shiga toxins and intimin genes (stx1, stx2, andeaeA). The results of PCR confirmed all (50) isolates were harbor at least one virulence gene.Out of 50 isolates 20 (40%) carried stx2 gene alone, the percentages of the carrier were (66.7 %,41.7% and 23.5%) from human, sheep and cattle samples, respectively. The genes (stx1 andstx2) were detected together in 9/50 (18%), represent (52.9%) of cattle isolates. The intimin gene(eaeA) alone was detected in 2/50 (4%), represent (11.8%) of cattle isolates. (28%) of isolatesharbor (stx2 and eaeA) genes, the isolates belong to human and sheep isolates (33.3%) and(45.8%), respectively. Presence of the genes (stx1, stx2, and eaeA) were discovered in (10%)of isolates, (11.8%) of cattle and (12.5%) of sheep. The isolates were resistant to ampicillin, tetracycline (92%, 74%), respectively. However, theisolates were susceptible to imipenem, gentamycin, chloramphenicol, ciprofloxacin, andcefotaxime with a ratio of 100%, 92%, 78%, 68%, and 58%, respectively.

In the present study, a total of 150 mastitis milk samples were collected from sheep andgoat (75 for each one) and were analyzed for the presence of S.aureus.. The obtainedresults indicate that this bacterium observed in 20% of these samples (21.33% from sheepand 18.66% from goat) .The study of antibiotic susceptibility test to 9 different antibioticsshowed that S. aureus was 100% resistant to penicillin and 100% sensitive tovancomycin, gentamycin , clarithromycin and chloramphenicol . whereas for cefoxitin(alternative to methicillin) resistance was 47%.There were a variable sensitivitypercentage for the rest of antibiotics: Tetracycline (70%), Ciprofloxacin (80%) ,Clindamycin (83%). The biofilm-forming ability of S. aureus was evaluated viamicrotiter plates and the result revealed that, all the studied isolates were either moderatebiofilm producer or weak biofilm producer while the non-biofilm producer and strongbiofilm producer were not detected among the tested isolate.The relationship betweenbiofilm formation and resistance to methicillin showed there as no significant differences(P>0.05) in the percentage of weak and moderate biofilm producers between MRSA andMSSA isolates. PCR analysis was applied to DNA extracted from S.aureus isolates frommilk samples .The results of PCR assay revealed that all S.aureus isolates gave positiveresults for both icaA and icaD genes (100%) with Product size 151 and 211 bp,respectively.Results of this study indicate that biofilm producing S.aureus have a major role player onthe occurrence of mastitis .In addition, there was high prevalence of MRSA isolates(47%) in mastitic milk at the study area
اظهر المزيد [+] اقل [-]Histological and Biometrical Study of The Adult Local Bull Testis in Duhok Province النص الكامل
2022
The purpose of this research was to assess some histological parameters and activity between the left and right testis of ten adult local bulls that were collected from the Duhok slaughterhouse /Iraq. The left and right testis specimens were routinely processed and stained with hematoxylin and eosin. The tunica albuginea is a thick sheet of dense, fibrous connective tissue that covers testicular tissue. The mean thickness of the tunics of an adult local bull differed significantly (p≤0.05) between the left and right testis. Thin septa that extended from the tunica albuginea to the mediastinum testis separated the parenchyma into lobules. Tortuous seminiferous tubules were found in each lobule. The mean diameter of the rounded seminiferous tubule of the left testicle was substantially (P<0.05) larger than that the right testicle. Tubular differential index (TDI) and spermatogenesis index (SPI) were found substantially (P<0.05) higher in the left testicle than the right. Sertoli cells are roughly pyramidal in shape, with an oval nucleus. The spermatogonia were circular or cuboidal in shape and possessed a round, dark nuclei. The large spherical nuclei and granular chromatin aggregates were found in primary spermatocytes. The spherical spermatids were small and elongated spermatids were developed. Some seminiferous tubules contain both spermatids and spermatozoa. Either narrow strands of interstitial tissue among two seminiferous tubules or massive triangular and quadrangular interstitial spaces separate up to three tubules. It contains only blood capillaries, a few Leydig cells, and some fibroblast cells, or extensive vessels (blood and lymph), as well as many Leydig cells. Within inter tubular spaces, Leydig cells were found as singular or in clusters. It was concluded that the thickness of the tunica albuginea, the diameter of the seminiferous tubules, the tubular differential index, and the spermatogenesis index were higher in the left testis of local adult bulls than the right testis.

Thuraya Hashosh et al
The goal of the present study was to isolate and identify (CRISPR-Cas) elements in S. epidermidis (MRSE) from 300 samples collected from various sources. Culture techniques, biochemical tests and VITEK2 system were used for confirming of Staphylococcus epidermidis isolation. The partial sequencing of the 16s rRNA gene was evaluated and compared with those in the Gene Bank to find differences in the sequence using the BLAST tool (http://www.ncbi.nlm.nih.gov). On the other hand, the CRISPR-Cas system was examined in all isolates of multidrug-resistant S. epidermidis in which the SECR1 and SECR2 elements were not found. The cas6 element was found in all of the tested bacterial strains. Susceptibility tests were done using the disc diffusion method after identification. Antibiotic resistance testing on S. epidermidis isolates revealed the highest percentage of multi-resistance to ampicillin, ceftriaxone, chloramphenicol, cefalexin, vancomycin, nalidixic acid at 100%. Moreover, S. epidermidis isolates showed intermediate effect against amoxillin-clavulanic acid, tobramycin, neomycin, oxacillin, tetracycline and methicillin. However, S. epidermidis isolates were found to be the most sensitive to erythromycin, norfloxacin and rifampicin. The CRISPR-Cas system can be found in S. epidermidis isolates from a variety of local sources and that the appearance of the CRISPR system in S. epidermidis isolates plays a unique role in antibiotic suitability.
