Abstract Purpose of Review In this review, we report on the state of knowledge about human Q fever in Brazil and on the Guiana Shield, an Amazonian region located in northeastern South America. There is a contrast between French Guiana, where the incidence of this disease is the highest in the world, and other countries where this disease is practically non-existent. Recent Findings Recent findings are essentially in French Guiana where a unique strain MST17 has been identified; it is probably more virulent than those usually found with a particularly marked pulmonary tropism, a mysterious animal reservoir, a geographical distribution that raises questions. Summary Q fever is a bacterial zoonosis due to Coxiella burnetii that has been reported worldwide. On the Guiana Shield, a region mostly covered by Amazonian forest, which encompasses the Venezuelan State of Bolivar, Guyana, Suriname, French Guiana, and the Brazilian State of Amapá, the situation is very heterogeneous. While French Guiana is the region reporting the highest incidence of this disease in the world, with a single infecting clone (MST 117) and a unique epidemiological cycle, it has hardly ever been reported in other countries in the region. This absence of cases raises many questions and is probably due to massive under-diagnosis. Studies should estimate comprehensively the true burden of this disease in the region.

Abstract A description is provided for Isthmiella faullii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Apparently confined to Abies balsamea. DISEASE: Causes a needle blight of Abies balsamea. According to Darker (1932), it 'is the commonest and most destructive of the Hypodermataceae on Abies balsamea in eastern North America'. It is particularly damaging to seedlings and juvenile plants. In northern Ontario, from where the disease was originally identified, infection occurs during the summer, but signs of the disease do not appear until the following spring, when needles become brown and conidiomata develop, conidia being discharged in July, and shortly after this ascomata begin to form, maturing in July of the following year. GEOGRAPHICAL DISTRIBUTION: Reported from Canada: Nova Scotia, Ontario, Quebec and USA: Michigan and New Hampshire. TRANSMISSION: Through air dispersal of ascospores, which directly infect the leaves (Darker, 1932).

Abstract A description is provided for Mycosphaerella iridis, a terrestrial fungus, parasitic and causing brownish spots on the distal parts of older leaves. Some information on its habitats, economic impacts, dispersal and transmission and conservation status is given, along with details of its geographical distribution (Africa (Zambia, Zimbabwe), North America (Canada (British Columbia, Nova Scotia, Ontario, Saskachewan, Quebec), USA (California, Colorado, Idaho, Indiana, New jersey, New Mexico, North Carolina, Utah, Wyoming), South America (Venezuela), Asia (Armenia, China, Cyprus, Georgia, India (Himachal Pradesh, Jammu & Kashmir), Iran, Kazakhstan (Alma-Atinskaya oblast, Chimkentskaya oblast), Kyrgyzstan, Turkey, Turkmenistan), Australasia (New Zealand), Caribbean (St. Vincent), Europe (Austria, Belgium, former Czechoslovakia, Denmark, Estonia, France, Germany, Greece, Hungary, Ireland, Italy, Netherlands, Norway, Poland, Portugal, Romania, Russia (Leningradskaya oblast, Novgorodskaya oblast, Pskovskaya oblast, Yaroslavskaya oblast), Slovakia, Spain, Sweden, Switzerland, Ukraine, UK))) and hosts.

Abstract A description is provided for Pucciniastrum americanum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pycnia and aecia on Picea glauca (=P. canadensis), uredia and telia on Rubus idaeus (incl. R. strigosus) and R. leucodermis (raspberries). DISEASE: Needle rust of white spruce. Late leaf rust or late yellow rust of raspberry, infecting canes, leaves, petioles, calyces and fruits. GEOGRAPHICAL DISTRIBUTION: Canada and U.S.A. (widely distributed, recorded from British Columbia, Connecticut, Idaho, Illinois, Iowa, Mass., Md, Me, Montana, North Dakota, New Hamp., New Jersey, Nova Scotia, New York, Ohio, Ontario, Quebec, Vermont, Wisconsin, West Virginia). TRANSMISSION: Although the basidiospores infect Picea glauca (white spruce) (Darker, 1929) in some areas they probably play little part in the life cycle on raspberry since this rust is found on the latter host year after year in regions remote from any spruce trees (Anderson, 1956).

Abstract Two species of black widow spider (BWS—Latrodectus hesperus Chamberlin & Ivie and Latrodectus variolus Walckenaer) naturally occur in Canada and are capable of causing deleterious envenomation to humans. No Canadian literature exists on the frequency of envenomations by these species or the use of antivenom in the treatment of those patients. A review of primary Canadian arachnology data was undertaken to identify BWS populations. A retrospective review of the Health Canada Special Access Program records generated epidemiology and the utilization of antivenom for BWS envenomations in Canada. The geographical distribution of BWS species is limited to along the southern Canadian border. From January 2009 to December 2015, there were five BWS envenomations that required treatment with antivenom and all cases occurred in British Columbia. An average patient age of 41 yr ± 21 SD (range 7–59) was observed, along with three of the five patients being female. The average number of vials used for treatment was 2 ± 1 SD (range 1–3). BWS Antivenin was also obtained by facilities in Alberta, Ontario, and Nova Scotia, but not used in any of these jurisdictions. Further investigation is necessary to determine the annual incidence of BWS envenomations and if treatment with BWS antivenin is required.

The following communication is introductory to a few remarks on the Nova Scotian and Canadian Insects which I have received through the kindness of J.M. Jones, Esq., W. Saunders, Esq., and Prof. Croft.The study of the geographical distribution of Insects has become more interesting by the differnece of opinion as to the origin and diffusion of species. The insects of seperate arctic regions have a great muttual resemblance, and the difference between them increases in the successive concentric circles from the above regions towards the equator.

Annotated List

During the past four years Mr. Douglas C. Ferguson has collected dragonflies in Nova Scotia thereby greatly increasing our knowledge of the geographical distribution of these insects within the province. He very generously presented to the writer his entire collections comprising 327 specimens of 51 species, four of these being new records for the Maritime Provinces and two others being new for Nova Scotia. In the annotated list of species below these new records are indicated as follows: New records for the Maritime Provinces are indicated by a double asterisk (**). Records which are new for Nova Scotia only, are indicated by a single asterisk (*). A better representation of the widely distributed northern genus Somatochlora whould have been expected in a collection of this size made from the territory covered, in view of the fact that at least eight species are known to occur in thls territory. The reasons for their escaping capture is doubtless due, in part, to the restricted habitat occupied by many of the species, and in part to the difficulty of collecting specimens.
