Gharban HAJ. Molecular prevalence and phylogenetic confirmation of bovine trichomoniasis in aborted cows in Iraq. Vet World 2023; 16:580-587. [PMID: 37041823 PMCID: PMC10082752 DOI: 10.14202/vetworld.2023.580-587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2022] [Accepted: 02/07/2023] [Indexed: 04/13/2023] Open
Abstract
Background and Aim Bovine trichomoniasis, caused by Tritrichomonas foetus, is a venereal disease that is distributed in many countries, including Iraq. Compared with other abortive infectious diseases, prevalence of T. foetus is expected to be relatively low in the field by veterinarians. This study aimed to estimate the prevalence of T. foetus in aborted cows by conventional polymerase chain reaction (PCR) and phylogenetic analysis of local T. foetus isolates was documented in the National Center for Biotechnology Information as the first sequenced isolates from Iraq. Materials and Methods Vaginal fluids were collected from 62 aborted cows and examined by PCR. Data were reported for the following parameters: Vital signs (body temperature and respiratory and pulse rates), age (<4, 4-8, and >8 years), reproductive health status (premature calving, embryonic death, pyometra, and healthy newborn), breed (pure or crossbred), type of breeding (natural or artificial), bull-to-cow ratio (1:<10, 1:10-20, and 1:>20), contact of cow with bull(s) from other farmers (yes or no), and contact with stray animals (dogs and cats). Results A total of 20.97% of aborted cows were positive for T. foetus. Phylogenetic analysis for 10 positive local T. foetus isolates demonstrated high identity with the Thai (MN560972.2) and Chinese (MH115435.1) isolates, with an identity range of 98.8%-99.5% and 98.6%-99.3%, respectively. Clinical data showed that the vital signs differed insignificantly between cows positive and negative for T. foetus. Prevalence and risk of infection increased significantly in <4-year-old, early calving, embryonic death, crossbred, and naturally inseminated cows that had direct contact with bulls from other farmers, and contact with stray animals. Fetal pneumonia and death of premature calves were significant among positive aborted fetuses. Conclusion Tritrichomonas foetus is highly prevalent in aborted cows in Iraq and phylogenetic analysis demonstrated an identity between the local and global isolates, that is, Thai and Chinese, of cats.

Abstract
BACKGROUND: The bacterial contaminants in the semen are a major concern for most of the semen production laboratories because they adversely affect the semen quality. During sperm cryopreservation, the inclusion of antimicrobials in extenders may help to minimize bacterial growth.
However, due to bacterial resistance to commonly used antimicrobials, they cannot fully assure microbiological safety to the frozen semen. OBJECTIVE: To estimate the microbial load and antibiogram of microorganisms isolated from the fresh and frozen bull semen. MATERIALS AND METHODS:
The bacterial load was estimated in fresh and frozen semen samples of crossbred Frieswal bulls by the pour plate method. Microorganisms were identified as Gram positive and Gram negative by Gram staining. The representative bacterial colonies were streaked onto different specific media which
were further confirmed by biochemical tests. Bacterial isolates were subjected to in vitro antibiotic sensitivity test. RESULTS: The average microbial load of fresh and frozen semen samples was found to be 8397.4±524.31 cfu/mL and 680.87±105.41cfu/mL, respectively. Microorganisms
belonging to Staphylococcus aureus, Staphylococcus epidermidis, Proteus, Klebsiella, Bacillus cereus, Bacillus subtilis, Actinomyces, E. coli, Rhodococcus, Neisseria and Micrococcus were identified in the semen samples. The antibiotic sensitivity testing of the bacterial isolates
revealed that benzyl penicillin was found to be the least effective against the isolated organisms while gentamicin and spectinomycin were found to be most effective among the antibiotics used. Lincomycin, tylosin and streptomycin showed moderate efficacy against the bacterial isolates.
CONCLUSION: Gentamicin, tylosin, lincomycin, and spectinomycin (GTLS) antibiotic combination is more effective against bacterial isolates and may be added to semen extender to better control bacterial load and semen quality. .

Comparison between chlorhexidine and povidone-iodine solutions for flushing the preputial cavity on penile mucosa and semen bacterial counts in beef bulls. Theriogenology 2022; 193:114-119. [PMID: 36156423 DOI: 10.1016/j.theriogenology.2022.09.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 09/03/2022] [Accepted: 09/10/2022] [Indexed: 10/31/2022]
Abstract
The objectives of the present study were to estimate the number of colonies forming units (CFU) from penile mucosa and semen, the effect of two antiseptic solutions used to flush the preputial cavity to reduce the bacterial counts from those sites, and compare them. Six clinically healthy bulls between 15 and 16 mo old declared satisfactory potential breeders were used. A prospective, randomized, and controlled cross-over design was performed, in which each bull was first sampled from the penile mucosa and semen without treatment (control group) and 24 h later, after antiseptic preputial flushing (treated group). In the treated group, the preputial area was cleaned, the preputial hair was cut, urination was stimulated, prepuce area was scrubbed twice, and the preputial cavity was flushed with either 1% of povidone-iodine solution (POI; 500 mL) or 0.05% chlorhexidine digluconate (CHG; 500 mL), maintained for 10 min. Then, the preputial cavity was emptied and flushed with 500 mL of sterile saline solution. Next, the accessory sexual glands were massaged per rectum. Finally, protrusion, erection, and ejaculation were obtained by electroejaculation, and samples from penile mucosa and semen were collected for microbiological culture. The number of CFU was determined for each sample by enumerate total aerobic bacteria using Standard Plate Surface Count cultured for 48 h. In the first replicate, half of the bulls were treated with CHG, and the other half were treated with POI. After 58.8 ± 5.3 days (x ± SD) of wash-out period, the treatments were reverted, and the same protocols were applied again. In the control group, the median number of CFUs from the penile mucosa was 750,000 (range from 60,000 to 1,800,000) and the median number of CFUs in semen was 8,000,000 (700,000-45,000,000). The CFU in semen was higher than the penile mucosa (P = 0.005). Both antiseptic solutions reduced the median number of CFUs on the penile mucosa to 915 (P = 0.002) and in semen to 1,680 (P = 0.002). The antiseptic effect on the penile mucosa was higher for CHG solution (490) than for POI solution (6,650; P = 0.05). The antiseptic effect on semen of CHG was also greater (200) than for the POI solution (31,000; P = 0.05). It can be concluded that the median number of CFU was higher in semen compared with penile mucosa, and flushing the preputial cavity either with 0.05% CHG or 1% POI maintained for 10 min reduced the number of CFUs from penile mucosa and semen. The level of antiseptic activity was higher for CHG than for POI.

Abstract
BACKGROUND: In the pre-seed area of healthy Aceh cattle, it is possible to be contaminated with pathogenic bacteria that can interfere with the reproductive system. This study is needed to identify these pathogenic bacteria using a molecular approach, in an effort to prevent infection.
AIM: The aim of the present study was to construct phylogenetic tree relationships of Acinetobacter soli identified in the preputial area of Aceh cattle by molecular analysis using 16S rRNA gene sequencing.
MATERIALS AND METHODS: A total of 75 preputial specimens were obtained from Indrapuri’s Breeding and Forages Center of Aceh Cattles, Indrapuri district, Banda Aceh, Indonesia. The samples were processed for culture using standard conventional methods. The extraction of genomic DNA and the amplification of the 16S rRNA gene were assayed using polymerase chain reaction. A phylogenetic tree was constructed using distance matrices using the neighbor-joining model of the molecular evolutionary genetic analysis software 6.1 software.
RESULTS: The results showed that of 75 preputial swab samples, 18 (24%) were positive for A. soli isolates. There was a 100% sequence similarity to A. soli prototype strain B1 and a 99% similarity to Acinetobacter parvus prototype strain LUH4616, Acinetobacter baylyi strain B2, A. venetianus strain ATCC 31012, as well as a 99% similarity to Acinetobacter baumannii strain DSM 30007, the strain ATCC 19606, and the strain JCM 6841, respectively. We concluded that A. soli-positive presentation in the preparation of Aceh cattle has 100% sequence similarity of 16S rRNA with A. soli strain B1.
CONCLUSIONS: The conclusion of this study is that, based on the construction of a phylogenetic tree, it shows that 24% of the bacterial isolate is related to A. soli. It is essential to conduct a regular survey for bacterial contamination and to increase worker awareness and education about hygiene standards.

Abstract
Bacterial colonization of male reproductive tissues, cells, and fluids, and the subsequent impact of bacteria on the sperm architecture, activity, and fertilizing potential, has recently gained increased attention from the medical and scientific community. Current evidence strongly emphasizes the fact that the presence of bacteria in semen may have dire consequences on the resulting male fertility. Nevertheless, the molecular basis underlying bacteriospermia-associated suboptimal semen quality is sophisticated, multifactorial, and still needs further understanding. Bacterial adhesion and subsequent sperm agglutination and immobilization represent the most direct pathway of sperm-bacterial interactions. Furthermore, the release of bacterial toxins and leukocytic infiltration, associated with a massive outburst of reactive oxygen species, have been repeatedly associated with sperm dysfunction in bacteria-infested semen. This review serves as a summary of the present knowledge on bacteriospermia-associated male subfertility. Furthermore, we strived to outline the currently available methods for assessing bacterial profiles in semen and to outline the most promising strategies for the prevention and/or management of bacteriospermia in practice.

Abstract
Marine and estuarine environments are often affected by microbiological contamination that adversely affects their use and severely impacts human health. To examine the influence of anthropogenic activities, this study used two different ecosystems in Agadir Bay, to compare fecal indicator bacteria (FIB) and bacterial pathogen profiles over two years. Vibrio target pathogens were detected at a high frequency (49.3%), while a low percentage (5.5%) was noted for Salmonella. Apart from those mentioned above, several other pathogenic bacteria were detected such as Cronobacter sakzakii, Pseudomonas fluorescens, and Aeromonas hydrophila. We also investigated the antimicrobial resistance of the pathogenic bacteria isolated. Salmonella strains were sensitive to all the antibiotics used, except ampicillin, amoxicillin + Ac clavulanic and chloramphenicol. And Vibrio strains were resistant to ampicillin, cephalothin, amikacin, and ciprofloxacin. This study highlights the limitations of FIB in assessing the microbiological quality and the importance of environmental surveys in understanding the distribution of pathogens.

Abstract
The invasion of the male urogenital tract by microorganisms, and its subsequent effects on sperm fertilising ability, has not been well discussed in bucks. The present study was conducted to assess the bacterial load in fresh semen of the 2-6 years old bucks. For conducting the experiment, semen ejaculates from 18 bucks (6 from each breed namely Jakhrana, Jamunapari and Barbari) were used. We collected 5 ejaculates from each buck in each season (Summer-April to June, Rainy-July to Sept and Winter-November to January). Semen was collected with the artificial vagina (AV) method, and separate AV was used for each buck every time. The semen collection frequency was once in a week. Immediately after initial evaluation, collected semen samples were transferred to the microbiology laboratory of the institute. Thereafter, the semen samples were subjected to bacteriological examination to assess the microbial load. The results of the current study indicate that the microbial load in the semen was significantly (p < 0.05) higher in the Jamunapari bucks and in aged bucks. Bacteriospermia in different seasons was not significantly varied; however, nonsignificant increase in microbial load during the rainy season was observed. Overall, the average bacterial load in the semen of Jamunapari, Barbari and Jakhrana bucks was found 540.50 ± 55.88 CFU/ml, 391.81 ± 46.33CFU/ml and 388.93 ± 44.71 CFU/ml respectively. No significant difference in bacterial counts in the subsequent ejaculates among bucks was observed. Moreover, correlation analysis revealed that the proportions of motility, viability, plasma membrane integrity and acrosomal integrity were negatively influenced by the increased bacterial contamination of buck semen.

Abstract
The objectives of this trial were to estimate prevalence of bacteriospermia, to determine the bacterial load, and to isolate the types of bacteria as well as to assess the association between bacterial load and sperm quality traits in cryopreserved bull semen in field conditions in the South Wollo Zone. A total of 309 cryopreserved straws of semen from the Holstein Friesian (HF)-cross bull (n = 180 straws) and pure Jersey bull (n = 129 straws) were investigated. Bacteriological assessments of the presence of aerobic bacteria, estimation of bacterial count and bacterial isolation, as well as semen quality were performed. Aerobic bacterial contamination was prevalent in 38.8% of the semen straws. No significant difference in the prevalence of bacteriospermia was observed among bulls although the HF-cross bull had a higher prevalence (40.0%). But, significant difference in prevalence of bacteriospermia was found among semen ejaculates of the same bull. The risk of bacteriospermia in the HF-cross bull was higher (Odds ratio = 1.86, 95% CI = 0.168–20.26) compared to Jersey although not significant. Overall average bacterial load of 50.38 ± 16.29 colony-forming units (CFU)/ml (from nil to 1318.20 CFU/ml) was found. No significant difference in bacterial count among bulls and their ejaculates was observed. Moreover, correlation analysis revealed that the proportions of motility, live, and normal morphology were negatively influenced by an increase in the bacterial contamination of semen. In this study, three isolates of coagualse-negative Staphylococcus species and one isolate of Corynebacterium species were found. Average percentages of sperm motility (48.35 ± 1.23), live (66.08 ± 1.0), and normal morphology (80.62 ± 1.24) were observed. It was concluded that cryopreservation does not guarantee the quality of semen from bacterial contamination. Hence, meticulous care should be adopted to prevent contamination of semen by bacteria during collection, transportation, processing, and storage times.

Abstract
The dromedary camel (DC) is a strategic animal for the exploitation of the desert and unhospitable lands (arid and semiarid areas). These animals are a genetic resource, locally adapted and more resilient to these environs, that may significantly contribute to food security and sustainable development of marginal land areas. Artificial insemination is the least invasive, least expensive technique for improving genetic selection and minimising transmission of venereal disease among animals and herds. Besides semen preservation protocols, specific approaches for the development of DC semen collection centres - biosecurity measures, screening for infectious diseases, management of animals, welfare, nutrition, control of seasonality, training, hygiene of semen collection and processing - have been considered less important aspects. The aim of this research is to describe the aspects related to the development of a DC semen collection centre, summarising the latest studies in the field of welfare, reproduction and diseases, and describing biosecurity and hygiene aspects related to semen collection and handling. Scientific gaps and requirements for maximising the production of good quality and safe-to-use semen doses with minimal risks of disease transmission are also described.

Abstract
Aim: This research aimed to identify Staphylococcus species isolated from preputial swabs of healthy Aceh cattle, based on 16S ribosomal RNA gene analysis. Materials and Methods: The bacterium was isolated from preputial swabs of healthy Aceh cattle. The total DNA from the isolated bacteria was extracted using the Genomic DNA Mini Kit followed by polymerase chain reaction (PCR) amplification of the 16S rRNA gene. The product of PCR amplification was then sequenced and aligned to the known sequences in the GenBank database by multiple alignments and was also analyzed by bioinformatics software to construct a phylogenetic tree. Results: The results revealed that the bacterial isolate 3A had genetically closed relation to Staphylococcus pasteuri with <97% maximum identity. Data derived from the phylogenetic tree revealed that the bacterial isolate 3A was also related to Staphylococcus warneri, yet, it shows a different evolutionary distance with the ancestors (S. pasteuri). Conclusion: The results of this research suggested that the bacterium 3A, isolated from preputial swabs of healthy Aceh cattle, is a Staphylococcus species.

Abstract
Aim: The aim of this study was to investigate the effect of commercial egg yolk powder as an alternative to fresh egg yolk on freezability of Murrah buffalo semen. Materials and Methods: Semen samples (12) from 3 Murrah buffaloes (4 from each bull) with mass motility (≥3+) and total motility (70% and above) were utilized in this study. Immediately after collection, each sample was divided into four groups. Groups I was diluted up to 60×106 sperm/ml with tris extender containing 10% fresh egg yolk and Groups II, III, and IV were diluted up to 60×106 sperm/ml with tris extender containing 2%, 4%, and 6% egg yolk powder, respectively. Semen samples were processed and cryopreserved followed by examination of frozen semen samples after 24 h. Semen samples from each group were evaluated for total motility, viability, acrosomal integrity, abnormality, and hypo-osmotic swelling test (HOST) response after dilution, pre-freeze, and post-thaw stage. Results: Pre-freeze total motility was significantly (p<0.05) higher in Groups III and IV as compared to Groups I and II, and post-thaw total motility was significantly (p<0.01) higher in Group III as compared to other three groups. Viability was significantly (p<0.05) higher in Groups II, III, and IV than Group I at the pre-freeze stage. Significantly (p<0.01) higher viability and acrosomal integrity were recorded in Group III as compared to other three groups at the post-thaw stage. Abnormality was significantly (p<0.05) higher in Group IV than other three groups. HOST response was significantly (p<0.05) higher in Groups II and III than Groups I and IV at the pre-freeze and post-thaw stages. Conclusion: Addition of egg yolk powder at 4% level yielded significantly better results in terms of post-thaw semen quality as compared to the fresh egg yolk and other concentrations of egg yolk powder (2% and 6%).
