The engorged Hyalomma anatolicum anatolicum females were collected from healthy cattle of college farm as well as nearby private dairy farms and villages of Mhow to evaluate the period of oviposition and hatching of eggs of H. a. anatolicum under laboratory conditions. The present study recorded the period of oviposition and hatching of eggs (Mean ± SE) as 9.4 ± 0.54 and 21.9 ± 0.69 days, respectively.

The present investigation was undertaken to evaluate in vitro efficacy of cypermethrin against H. a.anatolicum. The engorged H. a.anatolicum females dropped on ground were collected from dairy farms of nearby villages of Mhow and were maintained in the laboratory till hatching of the eggs and larvae were used for further study. Larvae were placed in filter paper packets impregnated with 100, 200, 400, and 800 ppm concentrations of cypermethrin for 24 hours which revealed the per cent mortality 89.84, 93.70, 100 and 100%, while the corrected percent mortality and efficacy was found 89.30, 93.36, 100 and 100%

SummaryThis study determined the prevalence of theeaeA gene and its relationship to serotype and type of verotoxin produced in a collection of 432 verotoxigenicEscherichia coli(VTEC) obtained from the faeces of healthy cows and calves in a systematic random survey involving 80 dairy farms in Southwest Ontario. A PCR amplification procedure involving primer pairs which target the conserved central region of the O157:H7eaeA. gene showed that 151 (35·2%) strains were positive for the eaeA gene. All isolates (9–21 for each O group) of O groups 5, 26, 69, 84, 103, 111, 145 and 157 were positive, whereas all isolates (7–34 for each O group) of O groups 113, 132, and 153 and serotype O156:NM (38 isolates) were negative foreaeA. Seventy-three percent of 130 isolates ofeaeA-positive serotypes produced VT1 only compared with 20% of 253 isolates ofeaeA-negative serotypes. We conclude that there is a strong association between certain O groups and theeaeA gene, that serotypes ofeaeA-positive and eaeA-negative VTEC implicated in human and cattle disease are present at high frequency in the faeces of healthy cattle, that VT1 is more frequently associated witheaeA-positive than witheaeA-negative serogroups, and that the eaeA gene is more frequently found in VTEC from calves compared with VTEC from adult cattle.

An account is given of the morphological characteristics of the larvae of Hyalomma anatolicum anatolicum and H. a. excavatum. Emphasis is placed on the importance of chaetotaxy in the identification of the larvae.I am most grateful to Professor Don R. Arthur for reading the manuscript and for his most useful advice and encouragement. Also I wish to express my sincere thanks to Dr R. P. Chaudhuri, Dr C. M. Clifford, Dr V. Dhanda, Dr H. Hoogstraal and Profesor B. Feldman-Muhsam for supplying me with specimens.
