melitensis clone can cross species barriers and can establish a permanent reservoir in cattle and buffaloes. Presence of culture-positive animals at householders represent a high-risk factor for human infection. This knowledge is of significant importance in the control of brucellosis in bovines.his study was carried out to detect and characterize Coxiella burnetii in ruminant milk samples and in different tick species from seropositive farms in four Lebanese regions. Milk and tick samples were screened for C. burnetii presence by quantitative real-time PCR (qPCR) targeting IS1111 region followed by multispacer sequence typing (MST). The overall positive percentages of 9.6% (27/282) and 95.45% (84/88) for C. burnetii were recorded in ruminant milk and tick samples, respectively. In detail, the C. this website burnetii DNA was recorded in 52/54 (96.3%) of Rhipicephalus annulatus, 20/21 (95.24%) of Rhipicephalus turanicus, 6/6 (100%) of Hyalomma anatolicum, 5/6 (83.3%) of Rhipicephalus sanguineus and 1/1 of Rhipicephalus bursa. After genotyping of some IS1111-positive samples (17/111), different MST genotypes were identified. Out of 15 positive ticks, 10 were infected with MST2 genotype, 4 were infected with MST7 genotype and 1 was infected with MST57. Moreover, genotypes MST20 and MST58 were found in one cow and one goat milk samples, respectively. The present study confirmed the high genetic diversity of C. burnetii in Lebanon.Four ferns Blechnum orientale Linn. (BO), Dicranopteris linearis (Burm.f ) Underw. (DL), Marattia fraxinea Sm. (MF), and Microlepia speluncae (L.) Moore (MS) were extracted in varied combination of organic solvents followed by the preparation of eluates and isolation of secondary metabolites using chromatography on a glass column with silica gel as the fixed phase. The chemical components were identified using HPTLC and GC-MS analysis. The in vitro anti-trematodal activities of these eluates and compounds were evaluated against the sheep trematode worm Gastrothylax crumenifer (Plagiorrchiida Gastrothylacidae) at increasing concentrations (1 to 5 mg/mL), to find the relative motility (RM) values for 0 to 60 min of incubation as reflection of paralysis and death of the worms. Hedon-Fleig salt solution was used as negative control and Oxyclozanide® 1% as standard control. In vitro incubation study showed DL and MS extracts had strong trematodicidal activity. BO extract (5 mg/mL) produced moderate trematodicidal activity and MF (5 mg/mL) showed the least trematodicidal activity. Phytochemicals analysis revealed that the ferns are a potential source of trematodicidal compounds such as phytol isomers fern-8-ene and fern-9(11)-ene (terpenoid derivative), quercetin 7,3 ́,4 ́-trimethoxy (flavonoid derivative), etc., which offer scope for a more elaborate study for exploitation of ferns for human welfare.Staphylococcus pseudintermedius represents one of the most frequently bacteria isolated on dog's skin and it was recently recognized as a zoonotic pathogen responsible for severe diseases also in humans. This study aimed to define the occurrence of canine methicillin-resistant and methicillin-susceptible S. pseudintermedius (MRSP and MSSP) strains and to compare their antimicrobial profiles. The study was carried out at veterinary microbiology laboratories of two different Italian veterinary teaching hospitals, Milan and Naples, from 2015 to 2017. The statistical comparison of the results revealed significant differences in MRSP occurrence (p-value = 0.0435) and MRSP and MSSP antibiotic resistance profiles. In Milan, MRSP strains displayed significantly higher antibiotic resistance percentages (p less then 0.001) for some antibiotics, such as ceftriaxone and tobramycin, compared to those of Naples. Conversely, MSSP strains of Naples presented significantly higher rates (p less then 0.001) of resistance to amoxicillin/clavulanic acid, kanamycin, erythromycin, and tetracycline than to Milan isolates.
