A herd level analysis of urinary tract infection in dairy cattle.

Cystitis, urethritis and pyelonephritis in cattle most commonly result from ascending urinary tract infection with Corynebacterium renale, Corynebacterium cystidis, Corynebacterium pilosum or Escherichia coli. We describe the clinical, bacteriological, clinical-pathological and epidemiological findings in a dairy cattle herd with urinary tract infection (UTI). Blood and urine samples from 17 calves and 19 cows were submitted to laboratory examinations. Depression, muscle wasting, weakness and frequent urine dribbling were the main characteristics of UTI in calves. Affected cows showed weight loss and an abrupt reduction in feed intake and milk production. Enlargement of the left kidney and loss of normal lobulation were evident on rectal examination. E. coli was the most frequent cause of UTI but C. renale, alpha-haemolytic Streptococcus spp., Proteus spp. Pseudomonas aeruginosa, Klebsiella spp. and Oligella urethralis were isolated as well. Differences in total protein and several protein fractions were found between affected and healthy animals.

Retrospective epidemiological investigation of an outbreak of bovine ephemeral fever in 1991 affecting dairy cattle herds on the Mediterranean coastal plain.

From August to October 1991 bovine ephemeral fever (BEF) occurred sporadically in two localities in Israel. The morbidity and mortality rates reached 2.6% and 0.1%, respectively. Only 12/50 dairy cattle herds were clinically infected with BEF in the dairy community. The total morbidity rate reached 0.8%. The lowest morbidity rate was recorded in young heifers (5.5%) and the highest in adult cows (75%). Only heifers over the age of three months were clinically affected. The spread of the disease apparently followed the local prevailing night winds, which blow from east to west, i.e., from the land toward the sea. The morbidity period lasted 61 days. The low incidence and morbidity rates were possibly due to the low virulence of the virus strain involved in the 1991 epidemic. Retrospective analysis indicates that vectors - apparently mosquitoes - infected with BEF virus could have been overwintering.

Dermatitis in a dairy herd caused by Pelodera strongyloides (Nematoda: Rhabditidae).

A high rate (25%) of infestation of heifers in a dairy cattle herd caused by the saprophytic nematode Pelodera strongyloides is described. Management (crowded) and environmental conditions (moist and filthy) as well as the climate (temperature) apparently favoured the existence and continuation of the nematodes. These infested a large number of heifers by causing dermatitis in skin areas, which were in contact with the contaminated environment. The dermatitis is characterized by a marked thickening of the skin, which became wrinkled and scurfy with alopecia. Pruritus was not observed.

Four-year survey of urinary tract infections in calves in Israel.

The prevalence of urinary tract infections in calves aged seven days to three months in three dairy cattle herds ranged from 0.5 to 1.6 per cent, with an average of 1.1 per cent. The mortality rate reached 16.1 per cent. The morbidity rate of the female calves was 1.4 per cent and that of the male calves 0.8 per cent. The bacteria isolated from urine, and from vaginal and preputial swabs were Escherichia coli (35 per cent), Corynebacterium renale (14 per cent), plasma coagulase-negative Staphylococcus species (12 per cent), Pseudomonas aeruginosa (12 per cent), Proteus species (12 per cent) and Arcanobacterium pyogenes (5 per cent). The affected calves had a significantly lower serum concentration of inorganic phosphorus (P < 0.01).

Necrotizing stomatitis associated with Fusobacterium necrophorum in two goats.

Necrotizing stomatitis associated with Fusobacterium necrophorum in two goats is described. Arcanobacterium pyrogenes was the dominant component of the microbial flora cultured under aerobic condition. Treatment with penicillin, at a dose of 50 000 IU/kg for 6 days was used successfully in the cure of the disease.

Seasonal allergic dermatitis in sheep associated with Ctenocephalides and Culicoides bites.

The clinical, epidemiological and histopathological findings of two pruritic dermatites in sheep in Israel are described. The first type of dermatitis affected mainly young animals with lesions predominantly on the legs. It occurred from March to November, with a peak in June. The second type affected animals of all ages and was mainly on the ventrum. It was sporadic but occurred throughout the year with a peak in October. The morbidity rate of this syndrome reached 4.3% in one flock. The histopathology of both conditions was consistent with an allergic dermatitis. Fleas and midges were collected and identified as Ctenocephalides felis felis and various species of Culicoides. The population density, seasonal activity, geographical distribution and feeding behaviour preferences of the insects and the incidence of the two types of dermatitis suggest that fleas and midges were the causal agents. Flea and midge bite pruritic dermatoses should be considered in the differential diagnosis of sarcoptic and psoroptic mange.

Poisonous plants in the eastern Mediterranean basin.

Plants found in the eastern Mediterranean are discussed by their toxic principles and poisonous effects. Nitrate- and oxalate-containing plants, those with alkaloids and glycosides, plants inducing photosensitization and carrying tannins, and selected miscellaneous species of toxic plants are reviewed and their poisonous properties described.
