Prevalence and some risk factors of bovine heamotropic mycoplasma in Nineveh province - Iraq

Crimean-Congo hemorrhagic fever (CCHF) is described as a tick-borne viral zoonosis highly prevalent in Africa, Asia, Russia and the Balkans within the distribution range of ticks that belong to the genus Hyalomma. This research aimed to verify the seroprevalence of CCHF in cows employing Indirect enzyme-linked immunosorbent assay (I-ELISA) in Mosul city / Iraq, to examine some epidemiological risk factors related to the incidence of CCHF. From October 2019 -September 2020, one hundred eighty-four blood samples were taken from 3-8-year-old cattle of both sexes, from several management systems and origins, from various parts in Mosul city, 10 ml of blood was taken from the jugular vein in test tubes without anticoagulant to obtain the sera for I-ELISA test, while epidemiological data were obtained by interviewing the farm-owners. I-ELISA was applied to detect the antibodies of CCHF in the serum. The overall seroprevalence of CCHF in cows was 40/184 (21.7%). As for the risk factors associated with increased seroprevalence of the disease, an increase in seroprevalence rates was observed at ages 6, 7 and 8 years 30.5%, among females 26.3% and imported animals 27.5%. which showed that the serological prevalence in indoor feeding and outdoor feeding, was not significantly different (p<0.05). This study concluded that there is a higher seroprevalence of CCHF in Mosul city along with many risk factors related to its incidence.

Background and Aim: Hemotropic Mycoplasmas are small epierythrocytic bacteria that cause infectious anemia in several livestock species and in humans. Several reports have been made on hemoplasma infections in the south and north of Iraq, but there have been no studies in the middle Euphrates of Iraq. This study aimed to evaluate the presence of hemoplasma species in cattle in Al-Qadisiyah Province, Iraq. Materials and Methods: Two hundred blood samples were collected from cattle with pale mucous membrane from regions with heavy tick endemicity. The samples were analyzed for the presence of Rickettsia pathogens using thin blood smears and the Diff-Quik stains. All the samples were also examined using polymerase chain reaction (PCR) to amplify the 16S ribosomal ribonucleic acid (rRNA) gene to confirm the presence of the smear-identified microorganisms. Ten PCR positive samples were subjected to 16S rRNA partial gene sequencing to identify the species. Results: The findings uncovered positivity in 68 (34%) blood smears. PCR revealed positive confirmation in 18 (9%) of the 200 blood samples. Mycoplasma wenyonii and Candidatus mycoplasma hemobos were identified from 10 PCR positive samples. The nucleotide sequences of the isolates were closely related to isolates from cattle, buffalo, and dogs in Vietnam, Cuba, India, and Germany. Conclusion: Bovine hemoplasma infections are prevalent in cattle in the Al-Qadisiyah Province in Iraq. Our results may have significance for the development of control programs.

The study was performed to isolate and detect Mycoplasma as a causative agent of the upper respiratory tract and conjunctival infections in household dogs in Mosul city. One hundred household dogs of different ages, sex, and breed were subjected to the study, including 60 dogs suffering from moderate to severe respiratory infections and 40 healthy dogs in Mosul city from 1/2/2022 to 15/6/2022. Three hundred swabs were collected, including nasal swabs 100, oropharyngeal swabs 100, and conjunctival swabs 100. The swabs were cultured in Mycoplasma media and incubated at 37ºC with 5% CO2 in a candle jar for 4-14 days. Light and the dissecting microscope examined the growing colonies microscopically under low magnification. The colonies were also stained with modified Dienes stain. The results of the current study indicated that respiratory infections were predominant in young male household dogs compared with conjunctival infections in all examined dogs. The conjunctival infections were obvious only in Husky and Belgium dogs. The high isolation rate of Mycoplasma was from upper respiratory tract infections in diseased female dogs more than one-year age 100%. In contrast, the conjunctival infections were more dominant and had a higher isolation rate in less than one-year males. The current study revealed a high Mycoplasma isolation rate in respiratory swabs of Terrier and German dogs, while the conjunctival swabs were positive for mycoplasmal culture in Husky and Belgium dogs 100%. In conclusion, mycoplasmal infections were more dominant in upper respiratory infections in female German and Terrier dogs.
