(2015) Phylo-typing of clinical Escherichiacoli isolates originating from bovine mastitis and canine pyometra and urinary tract infection by means of quadruplex PCR, Veterinary Quarterly, 35:4, 194-199, DOI: 10.1080/01652176.2015 Background: Escherichia coli is one of the major causative agents of bovine mastitis worldwide, and is typically associated with acute, clinical mastitis. Besides this, E. coli strains which belong to the extra-intestinal pathogenic group are also the major cause of urinary tract infections and pyometra in dogs. Objectives: In this study, it was aimed to investigate phylo-groups/subgroups in 155 E. coli isolates obtained from acute bovine mastitis, 43 from urinary tract infections of dogs and 20 from canine pyometra by a formerly described triplex PCR and recently described new quadruplex polymerase chain reaction (PCR) method. Results: Group A 1 (n D 118; 76%) and B1 (n D 71; 46%) were found to be the most prevalent groups by triplex and quadruplex PCR assays in mastitis isolates, respectively. Phylo-typing of 43 urinary tract isolates also revealed that most of the isolates belonged to A 1 (n D 23; 54%) by triplex and B2 (n D 36; 84%) by quadruplex PCR assays. The isolates assigned as group A 1 (n D 17; 85%) by triplex PCR could not be classified by quadruplex PCR in pyometra isolates. Conclusions:The results support the hypothesis that E. coli strains isolated from bovine mastitis cases are environmental. Also, groups C, E and F were identified as new phylo-groups for the first time in acute bovine mastitis cases. The comparison of triplex PCR with quadruplex PCR results revealed that most of the groups assigned in triplex PCR were altered by quadruplex PCR assay.

1. In this study, the effect of chlorogenic acid extract from Lonicera japonica Thunb. on Mycoplasma gallisepticum infections and the performance of broiler flocks was investigated. 2. A total of 360 Ross-308 broiler chicks taken from M. gallisepticum seropositive flocks were divided equally into three groups designated as control (nothing administered), antibiotic (Tylosin tartrate given for the first 3 d and d 20-22) and test group (chlorogenic acid extract given twice a day on d 16 and 22). 3. Broiler performance analysis, serological tests (slide agglutination), molecular identification (polymerase chain reaction) and histopathological examination were performed to detect M. gallisepticum. 4. The results show that chlorogenic acid not only increases live body weight but is also an alternative treatment option in M. gallisepticum-infected broiler flocks.

Here, we report a case of neonatal calf meningitis due to Streptococcus gallolyticus subsp. gallolyticus (SGG). Clinical, pathological and microbiological findings were evaluated. API Strep, 16S rRNA gene sequencing, rpoB gene sequencing and sodA gene sequencing were used for the complete identification of SGG. This is the first documented report of neonatal calf meningitis due to SGG in veterinary medicine.
