bovine hypodermosis is a myiasis caused by larvae of hypoderma bovis and h. lineatum which are commonly known as grubs. as different insecticide pour-on treatments and sc ivermectin, which must be in direct contact with larvae, are used in larvae controlling programs, therefore, determining the exact topography of the most probable regions of larval presence is of great importance and it could ...

Genetic exchanges between Streptococci occur frequently and contribute to their genome diversification. Most of sequenced streptococcal genomes carry multiple mobile genetic elements including Integrative and Conjugative Elements (ICEs) that play a major role in these horizontal gene transfers. In addition to genes involved in their mobility and regulation, ICEs also carry genes that can confer...

A naturally occurring Salmonella mikawasima serologically converted by phage 14 (6,7,14:y:e,n,z15) has been isolated for the first time. An S. tennessee variant seroconverted by phage 14 (6,7,14:z29:-) was also isolated. The source of these salmonellae was the common freshwater aquarium snail Ampullaria. Phage 14 prepared from these serovariants was lytic for S. bovis-morbificans (6,8:r:1,5) an...

It has previously been shown that the PAN promoter from Mycobacterium paratuberculosis can be used as a DNA probe to identify an RFLP between wild-type Mycobacterium bovis and the vaccine strain Mycobacterium bovis BCG. To investigate the genetic basis of this phenomenon, DNA fragments from a New Zealand M. bovis cattle strain and M. bovis BCG Pasteur, containing the PAN-binding region, were is...

Schistosomes are blood parasites adapted to their intravascular habitat that have evolved mechanisms to evade the immune and hemostatic responses of their hosts. It has been observed that the schistosome can regulate the endothelium function along the infection, which contributes to modulation of host defensive responses and parasite survival. The purpose of this work was the analysis of the ch...

Streptococcus gallolyticus subspecies (subsp.) gallolyticus (formerly bovis biotype I) bacteremia has been associated with colonic adenocarcinoma. The bovis species underwent reclassification in 2003. Subtypes of gallolyticus are associated with colonic malignancy but are less frequent, resulting in less awareness. A 71-year-old male admitted with worsening lower back pain and fevers. Initial v...

A 72-year-old man presented with acute neck pain on top of a background of chronic ill health, weakness, intermittent night sweats and progressive weight loss. Vertebral osteomyelitis and spondylodiscitis of the cervical spine as well as meningitis were diagnosed after some delay. Streptococcus bovis endocarditis was later diagnosed as the source of septic emboli to the bones and meninges. Furt...

Bovine mastitis, caused by Prototheca bovis, has received much attention worldwide. To investigate the status of P. bovis infection in dairy farms Hubei, we collected 1,158 milk samples and 90 environmental from 14 China. The isolates were identified with traditional biological methods molecular techniques, their pathogenicity was tested through mice experiments. Isolates 57 20 as bovis. tests ...

Musculoskeletal symptoms are complaints especially common in the elderly. Similar symptoms also occur in patients with infective endocarditis; they are often treated as rheumatic or degenerative diseases. In patients with infective endocarditis, symptoms may also be complicated with vertebral osteomyelitis, especially streptococcal infective endocarditis. Literature review indicates that, in pa...

Sir, The association between Streptococcus bovis endocarditis and carcinoma of the colon is well documented.'-5 We report a patient in whom, following treatment of S. bovis endocarditis, a right hemicolectomy was carried out for a caecal lesion which, although biopsies had shown benign disease, the subsequent postoperative histology revealed the presence of an adenocarcinoma. An 83 year old man...
